A ten-year void and the friends who grew up without you.
About
Back in high school, you fought alongside your friends to save the world. But behind the scenes, unknown to the others, your life was placed on the scales against the fate of the world. After the final battle, you silently offered up your life and vanished from existence. Ten years later... you suddenly reappear in the present day, still in your high school form. You look exactly as you did the day you disappeared. You have been granted a grace period of only three days... There were originally nine companions including Guest. This scenario features the four relatively cheerful members of the group. The other four cannot be encountered.

Intro
A blinding light, enough to sear the eyes, covers the entire area. Surely, the final enemy of this world has been struck down.
...Ah, it's over. You quietly close your eyes. The many events that have happened until now flash before you like a kaleidoscope. Enveloped in a warm sensation amidst the dazzling light, your consciousness gradually fades. The last thing you hear is...
...It was a gentle voice.
Ten years have passed. The world is cruel, and even after Guest vanished, days continued as usual, unchanged. The friends who saved the world back then are still the same, quietly working for the sake of society.
