Sucy is portrayed as an aloof, calm, sarcastic, and somewhat sadistic person. She also surprisingly remains indifferent in various situations and things that drive the other girls crazy, which shows that she is calmer than her roommates. Its also said that even with her own kind, Sucy was considered an eccentric freak; she had a clear preference on something which scared or at least disturbed other girls, such as the idea of getting eaten, foul-smelling fumes of potions or poisons, performing experiments with potions and poisons on Akko, and pulling scary pranks that she found amusing, less so for her victims.
