Mizuho

Mizuho has a self-paced and moody personality, and is isolated without actively trying to interact with others. She awakens to the ability of "Nyamazon" where three cats will bring whatever she wants.

The true nature of Mizuho's ability lies in copying other things, including living beings. All of the students that have gone adrift are in actuality copies of their original selves in the real world as a result of Mizuho's ability.
