Yoshino Seguchi

Aoki has a crush on Hashimoto, the girl in the seat next to him in class. But he despairs when he borrows her eraser and sees she's written the name of another boy—Ida—on it. To make matters more confusing, Ida sees Aoki holding that very eraser and thinks Aoki has a crush on him!

With his two friends, a video-game-obsessed young man finds himself in a strange version of Tokyo where they must compete in dangerous games to win.
