Oyafune Suama

Oyafune Suama (親船 素甘) is the daughter of Oyafune Monaka, and is a math teacher at Kamijou Touma's school. She notes herself that she has to rely on high-quality clothes and make-up to make herself look good at her age, though from the narrative in the novels she would be a beauty if she takes off her glasses. Regardless of her good looks, Oyafune believes herself to be unattractive and thus carefully molds her outer appearance; she also displays an strict personality and seems to lack talent at knitting.

She has been shown to become extremely angry if she gets involved in any type of accident that will end up with her in a unsightly position; needless to said she has been involved with Touma's bad luck in more than one opportunity... And her reaction to said unsightly situations was so bad that she went to hit or attempt to hit Touma, even though she holds a teaching position.

Even though her mother is one of the 12 people in the Board of Directors, she has not shown any connection with the dark side of Academy City so far, from her's mother deep and loving care for Suama, it is hinted that she has a good relationship with her.

Chronology
After she discovered Touma, Motoharu, Aogami and Seiri fighting were sent to the teachers lounge after a scuffle was discovered a teacher at the school. The issue was about the three boys talking about which color would suit the bunny girl better (black, white or red), but Seiri with her own brand of justice, chokes Motoharu, kicks Aogami and headbutts Touma. As punishment she orders the four to pick the weeds off the school grounds, later when she comes back to check on them she finds Touma and Seiri playing fork ball(with Aogami and Motoharu having already skipped out) when they accidentally hit Suama and Touma goes to apologize but the angry Suama tries to strike Touma but she misses and he then asks if he can go home but she whips something at him prompting him to run away. She then rushes to back to the staff room while she she is rushing to get the dirt off herself and her clothes she starts to strip them off only for Touma to walk in on her, in response she began throwing math tools at him until he fled down the stairs.

At later point Shiokishi had her kidnapped to send a message to her mother, who opposed him in negotiations in military exports.

Design evolution
Appearing only rarely, Suama's design remains static throughout the series. Haimura designed her to look like a science teacher or bio researcher.
