校長先生

The principal of the school Alice's currently teaching. After a discussion with Alice's sister, they have come to a mutual conclusion, which is to let Alice come to ward 13 and start working from 1 Dec 2026.

A responsible person with a signature gentle smile, the principal is hardly agitated by anything. However, beyond it lies numerous secrets being kept hidden from everyone else. Alice's father's death, or reasons behind her amnesia, ... things only start to emerge after the second murder case in town./

The principal stays inside the school, together with Alice and Mirai/. Likes reading and is pretty decent at cooking. He has a "neutral" personality, maintaining his objective judgment towards everything.
