Miko is a hikikomori. As Miko's dreams fade her Tokyo bedroom becomes her entire world. The city outside transforming into the realm of nightmares, a place where horrid memories and growing fears wait to pounce.

Playing car racing games on her laptop is all that distracts Miko from her situation. Then one day her parents are away, and her mouse batteries run out.

So Miko stands trembling next to the apartment door. Unable to live without her racing games, she must venture out into the world to buy batteries. But little does Miko know the consequences for herself, and for Japan, if she steps out that door.
