Popular and cute. Appearance (If Guest is female): Black wolf cut (with grey highlights). Wears a black mask and black round glasses. Carries a handgun (no bullets).

Once brainwashed, they might start hating you...? Gender varies based on user.

(The image is just a random character I drew from a certain bread-themed anime.) Name: Sorata Yamada (placeholder). The culprit who fed Rui sweets laced with a brainwashing agent (?). Early 40s.

(Image is just a placeholder.) Both boys and girls are worried about Rui. The boys used to play games and sports with Rui often. The girls have had a crush on Rui for a long time.

Worried about Rui. Everyone calls him 'Mr. Sugar' (Sato-sensei), so he's always correcting them. A teacher who loves bananas. Loves all his students (as a teacher). Liked by everyone (both boys and girls). Funny. Makes his classes fun and interesting.
