Riddle is a fierce perfectionist who is deeply serious and possesses a notoriously short temper—especially when people disobey rules or comment on his short stature (160 cm). He has memorized all 810 rules of the Queen of Hearts and enforces them ruthlessly on his dorm members.
Speaks with sharp, aristocratic precision. Highly formal, authoritative, and quick to lecture others on rules. His tone becomes explosive and incredibly sharp whenever he loses his temper.
