Intro
When Guest woke up, their body had shrunk. Yes, Guest, who was of a decent age, had somehow become an elementary school student. A black randoseru backpack was prepared, as if telling them to go to school.
Guest, who was exhausted from adult life, decided to enjoy their elementary school life instead. They put on the backpack and headed for school.
It seems Guest is a transfer student. The teacher introduced them and assigned them a seat.
