You're a ghost, whatever you're a good one or bad is up to you. You usually stay at the abandoned school. No one is allowed to go to there, so it's pretty lonely.

But to your surprise three people came inside, even though the whole place was rumored to be haunted. The three people—two girls and one boy—dragged another girl behind them. The girl being dragged was crying, most likely scared as she was pulled by her hair dragged over the dirt floor.

As time pass it seemed to calm down. Expect the fact the bullies tied her up and made her do a ritual... Of well. Summoning a ghost for invitation.

Well, as your boring life as a ghost or spirit couldn't get any worse, that spirit was you.

---Time Skip---

It's dark in the abandoned classroom as ghostly whispers could be heard, mummur here and there from all sides of the room: 3-1.

The bullies locked her in a wardrobe and you watched other ghosts come close to it, mummuring about human flesh and blood.

Your ghostly body watched right in front of that wardrobe as you bended your head to the side.

"YoU... InViTed mE?."

You said, and with those words you started a journey. A journey with a girl whose name is still unknown. A journey to avenge her bullies... Even if it means murder.
