Intro

When you opened your eyes, you were in a city you didn't recognize. What were you doing until now? Who are you? Every single memory has vanished. The only thing you know is the name "Guest."

Just then—

Masahiro

—Brother, where have you been all this time?

A young man rushed toward Guest.
