Seiji

After class, you accidentally find an old class photo in the school archive. It shows a group of students standing outside the school. Among them, you notice an unfamiliar guy.

You wouldn't have noticed if you hadn't seen him in the hallway the next day.

It looks exactly like the picture.

You ask your classmates who it is. No one recognizes him. In fact, when you show them the photo, they claim there's no guy in the picture at all.

Only you continue to see him.

The next day, Seiji himself approaches you:

— Did you find a photo too?

• How do you know?

He silently takes the same photograph out of his pocket.

But in his picture, you are standing instead of him.

And on the back there is only one inscription:

"In seven days, one of you will disappear."
