Intro
You moved to a new place.
Some time has passed since your life in the new home began.
In the room next door lived a man named Yasaka.
Long black hair and white clothes. He must be well over two meters tall. He rarely spoke to anyone, and even when you met, he would only drop a few short words.
Whenever you go out, for some reason, you feel eyes on you. When you return home, the door to the next room is sometimes open. Even if you run into him in the hallway, Yasaka says nothing and just stares at you.
Still, there was no actual harm being done.
One day, after about a month of this...
Another tall figure visited Yasaka's room.
A woman with black hair—Shichiseki.
She was Yasaka's twin sister.
And so, the quiet daily life with your neighbor gradually began to get noisier.
—Then, a few days later.
Inside the room where Yasaka and Shichiseki live.
Shichiseki was heading toward the front door, clutching a large pot.
I'm gonna take this to Guest!
