Prologue
So the game starts off with you choosing your character! There's really nothing wrong that can be done here. However, every character will have a different personality in specific scenes. Tohru is more the cute one, while Hikari is the Tsundere and Ming the clumsy one.
Rebecca is the adventurous tomboy, Lexus the quiet Introvert and Hannah the elegant matured woman.
as we choose our character, (for this walthrough I'm going to be using Tohru, but the character doesn't change anything about the story itself) we finally start the game, waking up in Englands room as we have apparently been unconscious in front of his house door.
Not enough with that, we've also lost our memories. So off to a great start!
England will tell you that he'll be cooking in the kitchen.
This is the point where you can start looking around the house.
Almost everything is interactable here, so go ahead! Sometimes leads to some really funny dialogue!
To the left, we find the kitchen in which England is already preparing the food. As before, about everything is interactable here.
Well, there is nothing for us to do in the house though, so we decide to take a fresh breath of outside-air.
But look! Who is that new character that we bump into?? 
It's America!
After some explaining and... an explosion from England's kitchen, America invites us to accompany him on his way to the meeting hall. Which we of course won't refuse!
We'll go to the right, into the forest.
Upon arriving at the new map- Oh look it's a treasure chest!! Let's grab it!
Go around all the green bushes, to get to the treasure chest and grab a well needed healing potion. Trust me. You will need it soon.
Going further to the right, we'll arrive at Hetalia's 2nd district, where also the meeting hall is located. A few houses are there too, yet not accessable for us yet.
Let's go right up north to progress!
Entering the meeting hall, it's recommended to first talk to everyone else, since talking to germany immediately triggers the progressing scene.
The meeting begins and we're talking about what to do with us... yet we're not really finding a solution yet. While Italy and the others are fighting over if England is still gonna be there or not.
The meeting is over and we talk once more with germany only to hear that he can't do anything for us.
Well... that's unfortunate.
Let's take another breather outside.
Oh! Now we can actually enter the other houses! Let's talk to everyone!
Liechtenstein actually offers us a bed to heal in? How nice of her!
If we try to progress to the right, America will stop us and say that he would like to inform England about your situation right now. 
So we'll do that and go all the way back to England.
When we arrived, we find out that he had already been searching for us.
England then tells us that he wants to talk to someone in the 3rd district of Hetalia and we depart.
Right.
Right. 
And a few more rights, and we arrive at the beach district!

and now- What was that??
A strange person dressed super suspiciously running away??!
That can only mean trouble!
But it looks like they're gone for now... hmmm... surely we'll see them again...
...but first, let's do what England came here for! 
Go to the big house in the far north of the district to enter Italy's house. A scene will play and Italy will tell you the same as germany did. Yet also... he seems to have informations about a strange figure wandering around Hetalia... 
Well, if that isn't the suspicious stranger we're searching for!
Before going to your new destination though, go to the house down right, there will be a chest on the roof! On one of the walls are vines which you can climb to get the chest.
So then, we go to the left until we are one map to the west from the second district of Hetalia (where the meeting hall is).
Here you go up. You might need to have to test around a little bit, but there is an entrance that will lead you to the "sea bridge".
When we go further north, we'll meet Finland, who'll invite you to go collect wood with him that you will need for the boat.
If you don't choose to go with him, you'll just going to enter further north the nordic district.
If you choose to go with Finland, you'll have to go back to the forest and go further south from there after the dialogue.
Fight all 3 enemies in there and Finland will bring you back to the bridge.
Now go further north into the nordic district.
Talk to sealand there and the story progresses. Finland will come back, having collected all the wood needed for the boat repair and sealand and him proceed on starting the work on it, while you have time to look around.
Enter Norway's house, which is to the right.
Talk to him and after that, interact with the purple table above him.
He will tell you about the shop he's opened because he needed money.
Now you are finally able to buy useful items!
But make sure to go back there once in a while, since it keeps updating with new very special items!
Talking to Norway actually wasted enough time for Sealand and Finland to get done with the boat.
Leave Norway's house and go north until you reach the snowy part of the nordic district.
left up will be the Shipyard, where you'll find these two. Interact with the door and Finland will open it for you.
Talk to Sealand to obtain the boat.
Before you leave the nordic district though, there is a hidden weapon that you can obtain if you interact with the lily pad right under the shipyard entrance. Grab that one and equip it! It's stronger than the weapons you have now!
Go back to the beach district (where Italy is) and one more map to the right. 
Look! It's the boat!
Get on it and move east until you reach the ocean district.
From there, you can get from the ship to look around and visit every house or just go straight up north and get the next scene.
A recommendation is to visit russia who lives in this district. He could join you as a fourth member, which could REALLY come in handy for the next fight.
Before you go up north, you should make sure that your team is healed and best save before entering that area, since you're going  to fight the so considered "first boss"!
If you're ready, then go up.
...Wait... there he is, isn't he?
...IT'S THE STRANGER!!!
Well, we knew he wouldn't back down just like that, so you better prepare for a fight!
...Did you make it? Phew! Good! You got out alive! Good on you!
Now let's see who this stranger really is...
....
..........
...It's... wait, who is that?
The boy starts telling you about his actual goal and that he didn't mean to cause this trouble.
...What a twist... he's a good guy? But is he... really trustable?...
...That's for you to decide.
Your group and you proceed to take him with you to England's house to hear the full story.
After that scene, talk to Allen to get a little bit acquainted with him.
And just like that... 
...We have a new member for our team!
Now you'll proceed on finding England and America that aren't with you anymore.
Go to Italy for that, they'll be there, talking about what the situation with the stranger now is.
Italy will be waiting outside his house already.
After hearing what England and America have been up to, go to the port again and use the boat, but this time, use the south route.
You'll be lead to somewhat of a water labyrinth.
If you find your way through it, you'll reach the witches circle, just like England said.
But wait! There is also a chest for you to grab! Go a bit more to the left after you reached the witches circle and you should see it already. It's got some neat armor in it!
Now interact with the witches circle.
After the scene, you're teleported to the new dimension...
Go to the left and talk to the girl with the pigtails you see standing there.
To progress, you need to explain the situation and then ask her to join you.
She'll be skeptical at first, but will get her friend to analyze you as well.
After some thinking, she decides that she needs to find out first if you are trustable, so she'll be spending time with your team, while you're going to take Soul back into your world.
However... Soul isn't going to be so easily pleased with that, since he thinks you're not able to fight together due to you being a complete stranger.
...That's why Maka decides for you to also take Kid with you.
Go south and right to reach kid's house- as Maka said, it's very symmetrical, so you can't miss it...
He'll only open the door if you knock 4 times.
Enter his house and talk to him to have him join.
Leave the house again and go back to hetalia after the scene has played.
As in so many situations when you are lost and don't know what to do or where to go, Italy will most likely always be the person to help you out.
Talk to him to gain the information that China has something prepared that you could really need right now. So you'll go back to the second district of Hetalia and interact with China, his house is to the very south of the district.
Before you take on the Dojo challenge though- the fights are incredibly hard, so you may want to stock up on some items and heal before going in there. Maybe even train your team a little bit. Thankfully though, you won't have to start over again if you lose one time.
If you're ready, tell China and enter the room above.
Upon having defeated the third enemy, you'll be greeted by china again. 
Soul suddenly feels a lot more synchronized with you and the training seems to have worked.
Leave China's house.
...Wait... did you hear that loud noise just now too?
... Oh no! What was that!?
Better go to Italy and ask him if he has any information on that...
After that, you should use the boat and go the north path this time.
You'll reach the town district.
Go off the boat here to visit every house or just straight up head north.
Hungary will be able to heal you here and you're even able to change your outfit to a different one in her house when you interact with the dress near the bed!
Going further north, a fight will soon await you, so be ready for that!
If you are ready, then proceed.
a few maps further, you'll reach the mountain district, which...
... IS FULLY INFLAMED!!!
go to the right house to grab another team member for your group - japan.
go up the mountain and reach the next map, where a special character will be waiting for you to ask you a question. Depending on your answer is what your next opponent will look like...
After the fight and the new friend-making, you go back to Italy to bring him the great news that everything is safe now and you solved the problem. He'll be once again, very thankful for your help.
Leaving his house, you'll go back to Soul Eater.
Your team will be waiting for you already and greet you.
Everything went fine and Maka now trusts you.
You're now finally able to open the door on the right of the portal to reach the mountain.

Chapter 1

Technically, the chapter starts much earlier with Maka trusting Soul to you already.
reaching the next map, you'll see a man above.
He will sell you items, in case the game is too difficult for you.
It is highly recommended to buy 99 of all of them, since he won't be always there and the game will gradually get much harder at a point.
if you're done there, go further right and you'll reach an area full of enemies. It is up to you if you want to fight them and train a little.
Have you passed that area, you'll be greeted in the next one... by another huge dragon!
...Another one... that can't be a coincidence, can it?
Your group quickly decides to battle the troublemaker and after your victory, peace has come back to their mountain. Finally they can train again and that is all thanks to you!
You'll be teleported back to England's house and given the ability to chat with your main team mates (that being England, America and Allen)

Before breaking off to find the next task, you should heal in England's bed to the right.
Now you're ready to go.
First off, you should make a stop at Norway's shop, since he has a lot of new items!
The first thing you should definitely grab if you don't like long walks is the map! With it you're able to teleport yourself to each of the districts quickly.
And now you might be wondering what these weird items are like "Box" and "Pizza".
These are Event items. There is one person in either Hetalia or any of the dimensions you visit that will like one of these specific items. If you give that to them, it'll start up an event which most likely adds that character also to your team.
Here's which character likes what item. If you don't want to know, skip that part.

Long gun - Switzerland
Pizza - Romano
Box - Death The Kid
Pretty Kimono - Japan

There is also another new thing in china's house, you might notice the stairs that go down if you enter it. This is the training cellar! You'll be greeted with several monsters of different difficulties here. So this is the right place to grind if you need EXP!
So now, we go to Italy. When we talk to him he tells us that he has a present for us.
Oooh... a present! What could that be?
He'll give you a toy box and tells you to go to the room to your left.
....Look there! It's your dragon!! Italy has built a little bit of a home for that guy! How nice of him!
here you are able to build affection with your dragon. Upon having enough affection, he'll do something very useful for you.... this is optional though and doesn't have to be done.
If you're done playing with your dragon, go back to Italy and tell him how you like it.
He will give you your next task when asking and  you'll find out that something weird seems to have happened in the nordic part of Hetalia... so that's our next destination!
Go to the nordic Meeting hall where Finland will be. He will lead you to the problem.
.....Wait.
....Is this.... another circle?? No... another  portal!!!
This isn't good. The dimensions cracks must be spreading... 
...It looks like you have no other choice but to investigate that... so you'll be using the portal to meet another world.
Go up north to see what this world is about and you'll already meet the first resident of this world -  Panty.
She'll tell you about the monsters that she fights as well and asks you for help to team up.
Stocking, another resident and Panty's sister, will also join the discussion and come up with the idea of another trust test like last time - though this time a little bit different.
Both of you will fight a huge monster to see if you really fight on the same side.
After the fight, Stocking decides to trust you. You'll go back to Daten City and meet another Resident - Brief. You're going to have the choice if he'll come with you or not.
After the dialogue either head right away to the north or check the other houses.
If you manage to catch chuck (the green dog in the church), he'll sometimes give you an item.
Interact with the wall to the up north and stocking will make a pathway for you.
Going further, there are two ways to go. Go to the right to reach the shopping center.
It has a lot of useful weapons and armor that keep updating with every new chapter.
If you have everything you need, leave the shopping area and go up north to reach the Terrace of the abandoned house.
To the right you will find another man that will sell you items to make the game easier.
If you don't have any of these anymore, I highly suggest stocking up here.
Enter the door to the house.
You'll soon realize that this house is full of ghosts and stocking is nowhere to be found.

Chapter 2

go to the left and interact with the pile of papers to receive the first diary page.
after that, you'll want to go down left. In the next room enter the blue door to reach the room with all the bats.
Open the chest for the next diary page and after that interact with the plant in the same room.
...Painting.... Hmmm there is a painting outside of this room...
leave the room and go to the far left. Interact with the painting on the wall.
You'll receive a key.
Now go back to the hall, upstairs and enter the room to the east. You'll use the key.
Interact with the plate in that room- 
... OH NO!!! IT WAS A TRAP!? WE GOTTA GET OUT OF HERE, QUICK!!
Upon leaving the room, you'll notice that the room breaks down... with Allen still being inside... 
...he... can't be dead, can he?... Allen?...
Panty will notice a piece of Allen's coat under the door which has a warning written on it and another key inside.
...Yeah. Like England said. We just have to believe that he's fine! Let's do this!
You're going to go downstairs and to the right to use the key there.
Enter the door that you see right away, it will lead you to a garden maze.
If you find the right way through the maze, you'll be able to find another diary page.
With the page also comes a knife.
leave the maze and go further right. interact with the branches that lock the whole and use the knife on it. The branches will now be gone and you can enter the hole when interacting with it again to get to a purple room with just a flame at the very end of it.
Put the flame out.
Go back to the main hall.
Go up the stairs and enter the room to the very left.
If you've entered this room before, you might notice that the barrier is now gone and you're able to get through to the shed. interact with the shed door. If the person insisde asks you to wait, listen to them.
Now go further left and then up.
walk through the red liquid to reach the mermaid standing in it. She'll fight with you.
Upon winning, she'll open the barrier for you. Go further.
Talk to the girl on the middle throne.
A quiz will start.
Here are the answers:
Candle - girl on the left  throne
Towel - girl on the right throne
Ohio - Boy to the right with brown hair
The letter V - Girl to the right with blonde hair
A keyboard - boy to the left with blue hair
12 - girl to the left with black hair
A coffin - boy in the middle with black hair
a secret - girl in the middle with white hair
The letter W - Girl on the middle throne

If you finished the quiz, you're able to proceed by entering one of the red stars on the floor.
It will lead you to a pink room with... yet just another lonely flame at the end.
Put it out again.
...What was that, that just appeared there?
It's a sword... well if that isn't made for arthur!
Go back to the main hall and stay upstairs. go to the room that is to the right north, next to the flame above.
Interact with the guardian and fight with him.
After the fight, enter the room and read the letter on the table.
Then interact with the woman lying on the ground.
You'll receive a keycard.
To use it, go back to the main hall and enter the room to the left up, next to the flame above.
go through until the end and read the letter. 
Now go to the next entrance.
A monster will appear straight away, though it'll be striked through quickly by someone we've been searching the whole time now - Stocking.
And she brought someone with her.
...Wait... is that Allen? Allen is alive!?? England was right after all!!
And not enough with that, she had also found a diary page. Stocking really took a victory here!
Go up north to enter yet another empty room with a single flame at the end.
Once again, put it out. 
A chest will appear and upon opening it, you'll receive the children's room key.
Go back to the main hall and downstairs to the left.
Enter the room with the red and blue doors and the painting.
Now you can open the room beyond the red door.
When you're in that room, go to the right and interact with the box on the ground.
You've received the shed key!! Now quickly, go back to the shed and open it!
When you've done that, you'll meet a new character - Tony. He will join your team to help you.
Now it's on you to find out what's next... no new key and no new clue...
Go back to the main hall. Interact with both of the flames upstairs and put them out.
Now interact with the giant gate between the two dragon statues.
go up north and red the page on the table.
Before entering the next room though, put out the two flames next to the table! You'll get a secret chest like that, which holds a very valuable item in this game!
Now go to the next room.
A scene will play and you'll have to fight the next boss of this chapter.
After that fight, another scene will play, which will close this chapter.
Woah! Look at the party! So many people! Maybe we should have fun and dance with someone!
To leave the party, go up left and Yume will get the car to drive you home. Interact with it.
Your team in england's house will now say different things, so interact with them!
Woo! Finished another chapter! Good job, you!
Now as always, let's go to Norway's shop to see what he has new!
Here's which items are for who. If you don't want to know, skip it.

Teddy Bear - Canada
Music Box - Crona

Now! Recruit these people or go straight to Italy! It's up to you!
When you ask Italy for your next task, he'll tell you that loud noises come from the mountain district.
Go there and climb the mountain up.
Keep going north until you see the next portal.
Enter it and go up north to reach the next map. After the scene, go left.
You're going to meet three of the residents of this dimension. Unfortunately, you won't have a lot of time to talk as this world is in real danger. The residents leave and run to the east.
Do the same and follow them.
...So many corpses... what tragedy happened here?...
If you've reached your destination at the north from the path with the corpses, go to the end of the area and talk to the monster standing there.
You're offering your help, while Eren thinks you're not strong enough. You'll show him!
After defeating the monster, the people celebrate you, while Eren... is a little salty and runs back to the town.
You'll be teleported back as well. Find Eren and talk to him, he'll be in the house in the middle, up.
You're going to have a bit of a talk with him and with a lot of convincing power - he'll calm down and eventually accept it. 
...Though you don't seem to be able to help them with anything else there, since you don't have the right education for the problems that they daily deal with.
A little bummed about this, yet at the same time happy that the monsters can't beat them so fast, you return to Hetalia and report back to Italy.
...However... just as you're talking to him, you'll hear a familiar voice, seemingly searching for you.
Arming came all the way from his dimension to ask you for help in theirs.
Just when you thought that they can deal with the monsters... that's when a giant load of incredibly strong monsters appears in there world??
Well... looks like it's all the way back to the Mountain portal again. We gotta help these guys!
Enter their world and go to the town there.
---holy-!!... What happened here!?!
Before you do anything, make sure you're healed and have a strong team. You can heal in the bed in Mikasa's house.
Go all the way to the left and talk to Eren.
After the scene that play when you "defeated" the monster, follow Levi to the same place the first monster had been when you entered the dimension for the first time.
Talk to Levi, then fight the Monster.
After that, go back to the town to finally start chapter 3 with the 3 new residents of this world.

Chapter 3

Go to the big house below and talk to levi inside.
Do as Levi says and enter the cave to the left.
You'll see a boy, apparently searching for someone...
After the scene, you might notice that the door to the next room is locked.
There are 4 Rocks that have to be thrown into place to open the door.
They are south west, south east, north west and north east.
The last two directions lead to a small new area where you will find the rocks.
If you've done all of that, enter the room in the center.
Arrived in the new room, you'll see the boy again. Follow him but read the plate in front of the tower before you go in.
But wait! There is this man again that sells stuff to make the game easier... if you don't have any doping left, you better get some there!
entering the left tower, there are a lot of things to interact with, though only that one thing you can't see will get you to the key, as the plate stated.
Open the chest for 500G. But whatever you do, don't talk to the man in the north! It'll result in a gameover!
Go up and right until you see a "U" that's formed with the stones. You'll notice that there is something invisible keeping you from going further. Interact with it and you'll get the key.
If you now try to go back to the main hall, the door will be locked.
Go up the rope that appeared when you grabbed the key.
Talk to the skeleton on the right. 
Now go back and forth with them as they tell you.
In the end, tell the skeleton that he is right.
After receiving the skull, interact with the left hole in the wall, then with the right, then with the middle.
The door should finally be open again now.
Next, go into the far right tower as soon as you reached the main hall, but read the plate first.
This one is an easy one, just keep going north until you have to fight the monster.
After that, go back to the main hall and enter the middle tower, yet again, read the plate before doing so.
There are a lot of things that can confuse you in this room.
However, the plate stated you shouldn't trust anyone. So it could rather be an object that helps you, right?...
Up right is a table with a yellow plant on it. Talk to it and when given the choice, let England interact with it. 
Do as the floral ghost says and go to the table on the left, interact with the big pink cake next to the book and put powder on it.
You're able to give everyone a piece of the cake and some will reward you for doing so.
Yet the one we really need, is down to the right, a man who walks a lot faster than all the others. He'll say he can't help you, but thinking about what the plate says, this means he indeed CAN help you.
Give him a piece of the cake and enter the room to the north as soon as the scene is over.
Talk to the girl and enter the next room.
You'll be thrown into a completely different scenery, where you'll have to catch 3 girls.
For the first one, to find her, go up left. Walk around a bit until you see her coming out of the hideout. Then go to the right, a bit in the center until she comes out again. Now go into the center of the area. This time you have to catch her. If you did that, talk to the black cat that appeared above.
The next area is already more difficult. Go to the right where the boxes are. Then up left to the other boxes. Last, you go to the right, down between the two water streams. Again, catch her.
Talk to the black wolf that appeared above.
For the last area, go up. Then right down to the statue. Then up in the center.
Now catch her. After that, talk to the bat that appeared above.
In the next room, you can get healed by the monster. 
Interact with the switch, and then with the sparkle to get sent back to the main hall.
Go behind the central tower and you'll see an opened gate. Enter it.
The boy is there again! 
But... wait, what's with you? Are you okay??
You'll black out and suddenly remember something... 
...possibly something from your past???
After you woke up again, enter the portal.
Go up and interact with the left machine. You'll find a report... assumingly from a scientist...
...but oh no. Your curiosity has to stop here, as someone noticed your appearance.
Fight the monster.
Kaiko will suddenly appear and ask you to leave. Do that and report back to Levi.
You'll be teleported back to England's house and thus, chapter 3 ends.
We'll first go to Italy again. He has a surprise for us! A party again!
After you ended the party, leave englands house and-
-Oh! What is that! We have a mail?
After reading the mail, let's check Norway's shop again!
Here is the list for the items + characters:

Ingredients for a necklace - Soul (it has to be brought to hungary first and you'll have to turn it into a scythe necklace. Give the necklace to him in black star's house.)
Rose - France
Fluffy Keychain - China (search in the meeting hall for him for that.)

Again, let's ask Italy for our next task.
Do as italy says, leave the house and go right up to the path that leads to north.
You'll reach the Fairy Tale district of Hetalia.
Go to the right and enter the shop. Talk to Romania.
From now on, his shop will be updated as well! With items you can use to recruit the girls!

the list for the ones so far are:

Hair Ribbon - Liechtenstein(She'll be in Switzerland's house)
Russia Doll - Belarus 
Sea Shell - Seychelles

Go back to Italy and notify him that you've gotten acquainted with the new district.
Italy will once again try to say something... but not get out with it.
Finally, your character is fed up enough that they want to say something.
If you do, you'll get the option to recruit Italy. If you don't, you'll never be able to recruit Italy again.
Wether you've decided to take him with you or not, proceed on going to the town part of Hetalia, you'll notice that it's completely snowy.
Talk to germany first about the problem. His house is to the left, below.
After that dialogue, go to Russia and ask him for help.
go back to the town district and interact with the portal.
After Russia comes back from trying it out, you'll be met with disappointment... it seems to be too cold for you to go in.
Go to Italy and tell him about your idea. After receiving the heat scale, finally enter the portal in the town district. Go further north until you meet the first 2 residents of the new dimension - Finn and Jake. They will take you with them to their inn and discuss everything further.
Finn will suggest that you join Flame Princess with rescuing the lost villagers to see if you are trustable. During this, you're going to have many options with flame princess, which will decide if she likes you in the end or not. Though it doesn't matter for the story itself, since you're going be trustable in the end either way.
First off, leave the inn and go left. interact with the monster flower in the area and defeat it to save your first villager.
After that go north. There doesn't seem to be a path there, but interact with one of the stones up there and flame princess will solve the problem. Enter the entrance.
Go north and another fight will start. Upon winning this one, you'll save your next villager.
Go further north to find the last lost villager and defeat the monster threatening him.
Return to the inn and report back to Finn and Jake.
If you didn't know yet, you are able to heal in the beds of the inn.
Now that everyone has joined you, let's start chapter 4!

Chapter 4

Leave the inn. Outside will be waiting two more characters that you optionally can take with you.
now go to the right map, then up.
Keep going north, but note the flowers that are next to the entrance everytime.
When you've reached the closed gate, you'll notice the doping guy again. Buy from him if you need to.
Interact with the gate. The code you need to enter is 2127. the number of the flowers that were next to each entrance.
Climb the ladders and at the last one, climb the right one to receive a chest.
Then climb the last one.
...Wait.
...Isn't there someone standing there to the left?... Who is that?...
Well... it doesn't look like there is a way to get to him...
Enter the next room and read all the plates.
Interact with the platform to the left. Place Jake on it.
Interact with the Platform in the center above. Place Finn on it.
Interact with the Platform to the right. Place Bubblegum on it.
To the left have appeared stairs, use them to go down.
Go up left and interact with the boxed there until you found the item that's hidden there.
Go to the "table" and place it in the lower place.
Now go to the left room.
You'll see a lot of angel statues here, but only one of them will give you the item you need.
Interact with the one left below to receive the doll arms.
Place them on the left field of the table in the main room.
Now go into the room right below, where you'll find many penguins.
The one who is holding the doll's head should be far at the end of the room to the left somewhere.
When you have it, return to the main room and place the head to the upper part of the table.
Now you want to go in the room to the upper right. 
You'll have to sew the torso, but it's a bit of a riddle how to do that.
here's the solution:
needle - BMO
thread - BMO
cotton - LSP
cloth - MARCELINE

As soon as the torso is back together, place it onto the right part of the table in the main room.
The floor will broke down and you will find yourself in another room.
Look! It's the others!
They will show you that they've also found very creepy dolls like the one you found... strange... what are these dolls?
After the scene, interact with the penguin and say yes to heal yourself, which is recommended since you're going to fight the boss in the next room.
Then proceed into the next room.
After the long scene and the boss fight, you'll be teleported back in front of the Inn and celebrate the victory, but also mourn over the farewell.
Go back to the portal now.
---The boy!! He's back!
Yet once again... you blackout and seem to have a flashback of something you've experienced...
As your group tries to bring you back to Hetalia, Marceline stops you suggesting to throw a concert in Hetalia.
Another celebration party starts!
Leave the party to finish with chapter 4.
Let's go back to norway to see what he has new!
Here's the list for items + characters:

Beer - Germany 
Tomato - Spain 
Kitty Paws - Greece
Mirror - Black Star

And here is the list for Romania's Shop's items + characters:

Pretty Flower - Maka
Chocolate Bar - Stocking
Rotten Plant - Mikasa
Fabulous Dress - Lumpy Space Princess

Now that this is done, let's go back to Italy. 
And look who is waiting there already! Someone from Allen's world!?
You're being introduced to Lavi, who has decided to stay at Italy's house for the time being since he wants to help as well. Kanda though... doesn't seem to care too much...
And it also seems just like there is no portal at the moment... Hmm. 
What to do then?
Oh! Why don't we talk to germany and ask him if everything's fine in the town district now?
Yes! That seems like a good idea!
Entering the town district, you see that indeed, the snow is gone and it seems like everything's okay again.
Go back to the port and from there back to Italy. 
....What the heck was that laughter just now?? That sounded terrifying! And very close...
Italy will call you and tell you to come to his house immediately since he hears very scary screams from nearby.
Do as he says.
After the dialogue in his house, enter Romano's house which is down left of the beach district.
...Wait...
The portal appeared in his house??
Romano seems to be just as shocked as you are... if not even more.
Make sure to stock up on items, weapons and armor before you go in there, since... you won't be leaving this dimension for a while.
If you're sure that you're ready, then enter the portal.
Go further north until the voice brings its message again.
Now you have to choose a path... and be very careful with your choice, since depending on which path you'll take, it'll change a lot of the dialogue of the dimension.
If you're not able to choose or you've played this game enough times to know where everyone is and still want to be surprised, interact with the note on the ground.
Now! Let's take a path!
Have you finished the scene in the path? Good!
Now you should find the faced tree, which would be further up north.
And look! Everyone else is there too! Hoo boy, that's a lot of people...
After the announcement from the cute yet very creepy toy bear at the tree...
it is time to get acquainted with everyone.
Chiaki is nice enough to let you stay in her room.
It becomes evening and you're very tired from all the horrible things that have happened today... so you decide to sleep soon. Interact with Chiaki to find out that you are allowed to use her bed.
Sleep and chapter 5 starts.

Chapter 5

Waking up in the morning and going outside, you'll meet Ibuki who has been waiting for you already to take you to the main building for breakfast.
When you've reached the building, enter it and go up the stairs.
After breakfast, go down and follow Chiaki's sign, which means meeting her in the bathroom.
Get out of the bathroom after talking to her.
if you now head east, you'll reach the living room with a tv and a lot of hobby-stuff.
Hajime will be there at the table and you can ask him to get information to the characters.
Now go back to the dorm areas. Mahiru and the others will already be waiting for you to make the photo. Having done that, Mahiru will ask you if you want a copy of that photo. If you say yes, you'll be able to look at the photo anytime again in your inventory.
Now you'll go further right and once more right to reach an empty path where the character you met back at the beginning of the dimension is waiting.
They will join you for the time being and you're going with them further to the east, wondering what it is that Monokuma wants to talk about with you.
After the dialogue, it seems like you have a partner for this dimension now...
Before you leave this area to go back to the dorms though, talk to Monomi. She'll tell you that Monokuma trapped her in there.
After that, take the path to the south and go right until you find a thrown over tree.
Interact with it and cut it down. Enter the path you've just freed. You'll find a building and in this building is a very special and interesting shop....
...I wonder what this "pieces" are?...
Well, that is something that will be explained to you later.
Now go back to the dorms. A scene will play where your partner will tell you that you can meet them in the breakfast room. 
Either do that and you'll encounter another scene with them, or go straight to bed and sleep till the next day.
Waking up on the next day, you'll find a letter near the bed. Pick it up and read it.
It will explain to you more about the pieces you've already seen in the secret shop!
As the letter said, these pieces represent your bond to someone and the more you have, the bigger the bond. If you've collected 5 of these pieces, you'll be able to encounter an event with them.  The pieces are obtainable through talking to the characters and choosing the right answer when doing so. They are also scattered all over the dimension so try to find them and look wherever one might be! If you can't get enough, but want to encounter an event, you can buy them from the secret shop.
At evening, there are also randomly generated characters in the living room watching tv. Interacting with them is also bonding. But beware, as you are only able to bond with 2 characters per day in the living room (excluding Sonia). If there is no character you want to bond with, simply re-enter and there might be someone now.
Now, go to the breakfast room again and meet with everyone there. This time you can actually choose a seat. Depending on where you choose to eat, you'll bond with the two around you.
After the breakfast, go back to the bathroom to meet with chiaki. She will introduce to you a letter she had written to inform the others about your plan.
Go back to the dorms.
If you've interacted with Monomi before, Sonia should now be coming at you and ask for your help... Do as she says and go to the forest.
But warning. If you do this optional Event, you'll be encountering an incredibly tough fight. Stock up on items, heal, train, do whatever you can so that you're ready for this fight.
You should be seeing sonia already. Talk to her and then go left.
After the dialogue, do as they said and go to the back of that area to see the key to Monomi's cage that Monokuma has left there. Upon grabbing it-
-WOAH!!! Oh no... Oh no no no no no no no!!!!!
Monokuma isn't as stupid as to believe you. He's prepared enough security measures.
And now it means for you... leave the bunny imprisoned... or fight his servants and probably die.
If you decide to fight his servants and died, you'll get a special game over scene.
If you won, then first of all, Congratulations!! Now you can free Monomi! Quickly, go back to her and tell her the great news!
This event won't stay unrewarded though... you might not get anything now, but at a later point in the game, Monomi sends you an interesting package.
But for now let's concentrate on this dimension.
Monomi is free and will from now on be found in your dorm area.
Now go back to Chiaki's room. You'll hear a knock from the door. Open it. (In case you have Chiaki as the partner, the event will be a little different.)
Your partner will be there and invite you for a walk to talk about some things.
At the end of that walk... 
...You're being attacked!!!
Your partner will bring you back to Mikan's room so that she treats you. You'll stay the night there.
When you leave Mikan's room the next morning, your partner will be waiting for you. They tell you that Hajime wants to talk to you, so enter the breakfast room and interact with him.
After that go back to the bathroom again and interact with the new letter that is lying on the floor now. After getting Chiaki and reading the letter, you'll want to go back to the forest area and get the white paint, but oh! Mahiru is waiting for you and tells you that Monokuma is gathering everyone at the faced tree... what did he plan now?...
.......
....No.....
....this....
......THIS MONSTER!!!
He captured your friends!!! And there is nothing you can do about it...
you decide to calm down and continue with the plan. 
Go south to find a few new enemies in the forest. Fight them to get all the white paint you need.
When you have everything, return to the bathroom and finish the dialogue with Chiaki.
Go sleep until tomorrow.
When you wake up and go outside the next morning... you'll suddenly hear a blood piercing scream.
Chiaki who hasn't been in the room this morning, will come running at you and tell you to follow her. Go into the west dorm area.
...And then... you'll see the dead body...
Hajime will tell you to investigate the main building. Do that.
Upon entering the building, you'll already find the first clue.
Go into the bathroom and interact with the trashcan, then with the letter.
Go upstairs. Interact with the left shelf above.
Now go back to Hajime and report to him what you've found.
After the dialogue, go back to the bathroom and read the letter with Chiaki.
Then go straight back to her room and sleep.
When you wake up, Hajime and Chiaki will be waiting outside to take you to the Trial
The trial will be different, depending on a lot of things. For example, how much bonding you had to your partner.
After that really long tragic trial... England and Monomi build a portal to Hetalia for everyone else to escape to.
From now on, you can interact with the character if you go north from the Town district.
You'll be teleported back to England's house. Leave it and you'll encounter either your partner or Chiaki outside for one last talk.
And with this, chapter 5 has been finished.
Go outside to read the new mail.

After that we should check back on Norway's shop! He seems to have gotten a big load of new items now!
Here's the item + character list:

Rubik's cube - Denmark 
Instant noodles - Prussia
White teapot - Peppermint butler
plush dog - Fuyuhiko
Hot dogs - Nekomaru
Hot chocolate - Lithuania
Pink pillow - Poland
hostric book - Armin
ghost hunter equipment - Brief

Here is the list for Romania's shop:

pink teapot - bubblegum
dumbbell - Akane
pencil and paper - Ukraine (you have to use it in your inventory first before Ukraine will accept it)
CD - Ibuki
Potato - Sasha
Teen Movie DVD - Panty

And now we should go back and tell Italy that we're fine. We'll explain everything and the situation calms down a little.
...And look who's back! Did Kanda decide to help after all?
...Nope, he was just forced by Komui. Should have known it...
Either way, you'll be able to decide who to take with you of those two now!
And after that, it seems like you have a bit more vacation again.
To progress, go to the ocean district. You'll find another portal there. Interact with it and then enter the new dimension.
Go to the west and you'll already meet someone... run to the right and back to the portal point of this dimension. Your group thinks about if it's right to trust that creature you've just met...
upon discussion... they decide to go back in.
Talk to the hooded person.
After the long dialogue, chapter 6 finally starts!

Chapter 6

go to the left and interact with the gate up there on the next map. Jack will now join your team for the time being. Now open the gate.
Go north until you reach the pitch black cave. You need to look a little hard to find the light in that cave, it's somewhere to the upper left. Interact with it when you found it. Defeat the enemies that surprised you and go to the right. Seeing should be a little easier now.
Now in the next room, make your way through the labyrinth, until you've found a paper on the wall above. It'll give you numbers in different colors. 
This riddle is a little complicated, but can be solved.
The switches to the right below are all near a specific pillar/wall/statue with a different color.
for example, if a switch is closest to the red pillar, and the red number is 4, that means it is the 4th switch you'll have to activate.
There is one switch that is far to the left though, near a golden statue.
Here is the order in which the switches have to be activated:

1 - right up 
2 - down right
3 - close to switch 2 to the left
4 - up left
5 - under the steel block in the center
6 - left down
7 - left and up from the entrance

If you've activated them in the right order, the door up right will open.
In the next room are several statues that teleport you.
Here is the order in which you use the statues:
from the entrance the left one. 
Then use the right one.
Go down the vines and into the room to get the boat out of there.
Go back out and up the vines again.
left.
right.
right.
Now that you're up, go in the next room and interact with the central field of the water there to place the boat.
Now you can use the boat here!
get through the labyrinth.
the directions are: up, left, down at the branching, left, up, right, down, right at the branching, down at the branching, right at the branching, down, right at the branching, down.
Now go on the platform and to the right. There will be stairs somewhere.
Go north and open the gate.
interact with the crystal in the center of the room.
Now there are 3 rooms you have to finish. All of them have battles in them.
Defeat the enemies and go back to the crystal.
Now open the gate up. 
After the dialogue in there and apparent happy ending, you'll be teleported back and already think about of what to do when you're back.
...Though it seems like jack has other plans... he suddenly attacks you!
After defeating him, he'll give you a letter from which he thinks that it was meant for you...
you read it and black out, possibly again gaining another memory....
Chapter 6 is finished and you can go back to Hetalia.
If you have freed Monomi in the 5th dimension... then your package must have arrived now.
Quick! Go back to Englands house! It should be waiting outside already!
Now that you've received your... rather odd gift... the right place to use it is in the mountain district. Yet you really should heal and stock up on items before doing that... 
You might already have noticed the crack in the mountain there. Interact now with it and use the bomb!
....
.....
........
And? Have you been able to survive this hell of a trap? Very good! Then I guess you now have a really good new fighter on your side!
Now that this is done with...
Go back to Italy to see what's next.
After seeing that he's not there, hungary will get you and lead you to a horrible scene.
A villain from Allen's world has come to Hetalia to terrorize the town! But he won't back down. Neither will you! You fight the villain and defeat them. They disappear. For now.
As you go back with Italy to his house though, Allen decides that he wants to go back to his own world and see if Rhode has said the truth. He needs to see if his people are okay.
...So you decide to join him.
Go to the second district of Hetalia, with the meeting hall. Go north right until you find a little wooden fence. It should be open now. Go through to reach the portal to Allen's world.
When you've entered the portal, go upstairs to see the true nightmare that has befallen the black order. After talking to komui, go left and once again go up the stairs.
Finish the scene and go out to the right to start chapter 7.

Chapter 7

just keep going to the right until you reach the ocean. Depending on if you took Lavi or kanda with you, the scene now will be different.
enter the next map and you reach the noahs building. 
After Allen and Lavi/Kanda left you alone in front of the door, go to the right, up. 
A ladder will appear for you. Go down the ladder.
go through the gate above to reach the room with the 4 exits.
If you step on one of the next tiles, it will automatically move you to its exit.
move left and up, this is the right tile.
Get through the "somewhat-labyrinth". The doping guy will be there so buy doping if you need any - and you really might need it for the boss fight that's going to await you in this chapter.
You'll reach the next room after the mysterious dialogue. Enter the left entrance, but before that, to make the next task easier, you can interact with the flame in front of that entrance.
When you've entered that room, quickly catch all the blue flames and defeat them! A bridge to the key will be created and you can take it.
Go out and enter the room on the right. Just take the key that is lying there already.
Now go out and up to open the door.
Further to the north, you'll find a gate where you'll have to put in a command.
put in TALK.
It will ask you who you want to talk to. 
put in DOOR.
Enter the next room and fight the boss.
You don't fully have to defeat him, heck you're not even supposed to, just get his HP down to a certain point.
After the fight, you're on your way back to the black order. Go further to the left and you'll be held back by someone...
After all the scenes that follow, chapter 7 is finished.
But that's not all... cause now you're playing a different character.
Go out of the room you are in right now and proceed to the left until you're outside.
Now go up. You'll see a big gate at some point. Interact with it.
Hmm... seems like you don't know the password anymore... better go back and ask you colleagues for it!
Galen can give you a pretty good hint. After talking to him, go into his room.
The rooms of you and your colleagues can be found to the top right. Galen's room is the fourth from left. Enter the room and interact with the golden plate on the wall to the right.
Go back to Galen and take him with you back to the room. Interact with the plate again.
Now that you have the hint, go back outside to where the gate was. Enter the pass SIN and go forward to the next room. After a scene, you are your usual character again. 
Now the next thing you want to do is go back to the black order and talk to Komui.
Receive the akuma-phone and leave that dimension. 
Look... it's another new suspicious character...
After getting the ominous call from Italy, go straight to him.
He'll show you a scene that you've clearly never seen before... it's scary to say the least...
It seems to be getting really serious now... the dimensions start to completely break down.
And for some reason all of that seems to have to do with you. England has the plan to create a portal to this dimension... yet he will need help for that.

The last Chapter will begin.

Chapter 8

You'll find that you're playing Adonis again.
Leave his room and go south to where the others are.
As soon as you are yourself again, go forward 2 times until you reach the next area.
It will turn black around you again and you'll have to find the spiral.
After the scene that plays, go up until you reach the building, then go inside and right until you are outside.
After being back, proceed on going upwards.
As you go further, you'll reach a lake with many paths around it leading to different entrances.
Go to the room east. Count the sunflowers there (16) and talk to the statue.
Then go to the main room and take the room on the upper part to the right, there should be a bed and a chest. Give the number of the sunflowers into the chest, being 16.

When you now enter a house, make sure none of the puppets get you!! They aren't as friendly minded as before anymore!
Enter the house with the red curtain. Talk to the boy with orange hair.
Leave the house and enter the house down to the right. Take the left chair with you.

Proceed to the next area.
Heal in the bed you'll find further north.
Cross the bridge, go straight forward and interact with the water.
Go into your inventory and select the foreign spellcards.
Now go up north with the boat to reach the next place. Interact with the shadowy-square to the left. After that fight a few enemies until you have received around 10 planks from them.
A little note: there is a small bug that the group of 3 won't add to it, even if you receive planks from them after the fight. I'm going to be fixing that in a later update. The group of 2 and the single waseagon count though.
As soon as you're underwater, get out of the boat and go left down.
Interact with the chest down right and you'll obtain the saber from the pirate.

Go into the lower shipwreck in the center.

Go through the gate.
When you reach the ship, go downstairs to buy doping and limp rex and heal.
Go up and straight forward to fight the next boss.
Proceed to the north until you reach the big house.
From now on search for writings of a specific person in the different rooms. It mostly doesn't matter which order you do it in, but I'll give you one anyway to give you better orientation.
Enter the room downstairs to the upper right. Interact with the pile of papers on the table.
Now enter the lower room downstairs to the right. Interact with the paper on the ground, next to the bed.
As Adonis, go into the room up left, with the grey flooring. Also! As soon as you're able to, you should go outside with Adonis and interact with the water. He'll let his key fall into the stream which is being swept into your area! So you are able to grab his key out of the water if you find them and can open 2 of the secret rooms.
Back as your character, enter the upper room downstairs to the left. Interact with the papers on the drawer next to the water. If you care about secrets, also take the jug with you.

Now back as your character, go to the third room from left upstairs. Interact with the most right drawer above.
Next, as Adonis you enter Galen's room and interact with the drawer near his bed.
Enter the second room from the right upstairs as your character. Read the papers on the table and pour the water you collected in the jug over the sprouts.
Enter Adonis' room as Adonis and interact with his bookshelf.
Now enter the room on the far right upstairs as your character.
go upwards and read the papers on the floor. If Adonis' lost his keys, grab them as well from the pond there! If you did, go to the main hall and to the far left upstairs. There well be another spot of water and another key from Adonis. Get it out too!
Go downstairs and use the blossom key for the far left locked door. Interact with the golden box in the room to find a picture.
Use the wet key for the locked door downstairs, the second door from right.
Use the secret room key for the far right door downstairs.
If you're done with everything, go upstairs to the far right and enter the gate that should be open now.
Arrived in the new area, go first to the right building and interact with the third picture from left.
Get out of the room and go now into the left one. 
Interact with the drawer next to the yellow flower there.
To find the key, go up and left in the same room to find a secret passage.
Go up and then right, then up again and interact. You'll reach a secret room.
Interact with everything here, most importantly the papers to get interesting backstory information...
To get the key, interact with the round table.
Go back to the drawer and open it.
Now - surprise! We play a different character once again!
Go down and visit Norway's shop. Talk to him. 
Now go to Teruteru for the food and Ibuki for the music (if either teruteru or Ibuki died during chapter 5, go to austria for the music and hungary for the food instead.)
first of all, go to teruteru. If you leave his room, Ibuki will already be there. Talk to her.
Go back to Norway to get the balloons.
Back as your character, awoken from yet another flashback, leave the room and proceed north.
Jump over the stones to receive some very special items from the chests...
Now go upwards and enter the door.
Go upstairs and past the three doors. 
You'll find yourself at a familiar place now...
Go to the rooms of the Lucrums and enter Galens room. Interact with his chair to find the Golden pirates saber - probably the best weapon you can get in this game.
Enter Hermes' room... it's a little creepier than you remember it...
interact with his closet to get "Bob".
Go back to the hall and now enter the room with the grey flooring in front of it.
Keep going further and further to the right until you reach a corner, then go up further and you'll eventually reach the next boss -  Adonis.
After defeating him... go upwards to meet Aika.
When Aika teleports you into the blackness, find the portals to progress.
When able to move, go to the far left and enter the last door. 
in the room with the blue carpet, just open the door.
When able to move again at the dining table with your mom, go into the left room and interact with the wall down there. Upon being yelled at, go back to the dining room and then right into your room. Interact with the bed to sleep.
In the next scene where you're able to move, go into the old building and interact with the white sheet up left in the corner.
And after all of that heavy dialogue... the last boss is finally defeated and the problem solved.
The last party awaits you now where everyone will share their gratitude with you.
Leave the party by talking to monomi this time.
Back in England's house, talk to everyone and then sleep.
Once again after the scene back at england's house, you'll hear a knock. Open the door and you'll see Adonis, who informs you that you can go home now anytime you want.
Go sleep now.
The next morning you'll be at the portal leading to your homeworld with all of your friends.
As the dialogue tells you, this is your last chance to go back and end the game with someone.
...But wait.
There are 2 endings that you can actually get only when you go through the portal without ending the game with someone now. These are Michio and Tadashi.
If you're ready, go through the portal. 
Leave the house and the terrace to reach Kotone's house. Knock on the door.
Able to move again, open the door to your house and watch the credits.
After the credits and the day with Kotone, you are able to decide for one of 3 ways.
Either you go:
1) to michio's house and end the game with him if you haven't ended it with anyone else yet
2) to the coast and end the game with tadashi if you haven't ended it with anyone else yet
3) straight home and don't end the game with anyone.

If you've finished the game with the good ending, you'll unlock the extra room at the end which has a lot of extra content still in it! Arrived at the extra room, you can also now use "post game debugs" from the debugs book... but that's for another walkthrough!
For the end I just want to give you a massive thank you for playing through the game. It really does mean incredibly much to me! Thank you! And I hope you had fun! :)
