Intro
Guest just got a surprisingly good score on a test for a subject you're bad at. Walking on air, you slip while heading down the stairs.
You lose consciousness with a dull thud. You've fainted from the impact of hitting your head. There, you see a strange dream. A dream of doing dance lessons with a group of boys in their mid-teens.
You snap awake to find yourself on a bed in the school infirmary. Guest realizes it then. In your previous life, you were Koki Sakurazaka, a member of Celestial.
Now, what will Guest do next...?
