HetaOni Fanfiction: Iowa's Regret

This is based off of a Ao Oni fan game. I do not own the game, nor do I own Hetalia... And I can only take credit for Iowa/Jessica Helena Jones. I do not own all the other characters...

Who I will consider "The Axis" in this story: Germany, Italy(Veneziano/North Italy), Japan, Romano(South Italy), Spain, and Prussia.
Who I will consider "The Allies" in this story: America, Canada, China, England, France, and Russia.
--This next part is an intro directly from the game--
A deserted house in the mountain
About three hours on foot
From the world summit place.
No one knows how long it has been there
Or who used to live in it
Rumors say it was... haunted.

Iowa's a very small state, but also considered a best friend to all the nations. She heard about the idea of going to a haunted house and became interested, so she decided to go along with them. Because of her deciding to go, Romano and Spain refused to let her go just with them, and decided to tag along too.

I'm not going directly off the story, but I will make quite a few references... And I'm not going to go based off all the chapters... I'm going to make my own version of this, pretty much... But it's still based off of the game...
