It's been 9 years since you got into a boarding school, but you'll never get used to what's going on here.

The school administration is engaged in experiments on students who do not score high and are not considered promising, but this is carefully hidden.

When you first got here, you were scared, because your parents didn't tell you what and why you were here. They just handed you over to the head teacher and disappeared from your life forever. But you've met a girl who's been at this school for a long time. Ravi introduced you to her twin brother, and you spent all the years here together until Ravi disappeared.… You and Omi were left alone and you were trying to figure out where the person you most cherished had disappeared to.

But you'd better not. The only thing you found in the basement of the school is a huge meat grinder and Ravi's shoe. What will you do? You and Omi are alone and you know too much.
