Fukiyose Seiri

Touma's classmate, Aisa's best friend, often takes up roles of the class representative even though it's Aogami's the class representative. She dislikes people (namely Touma) who give up on their life and blame it on bad luck. It's debatable if she is tsundere towards Touma or only dislikes him because of his attitude towards life and school in general but for sure she does have a sort of friendly relationship with him, even sometimes playing a role of tsukkomi for Touma who acts as the bokke. She is mentioned as the girl who is "pretty but lacks sex appeal". She is a health-product freak and is frequently ordering different health products from the television shopping channels. Her abilities have yet to be revealed.

During the events of the Daiahaisei was member of the commite of coordination for the schools and did her best to make the students to enjoy the games but later during one of those games she almost got accidentally killed by one of Oriana's Thompson flashcards which dried off her life energy but was saved by Touma who dispelled their effects. Thinking that the cause of her collapse was a sunstroke, she is later seen recovering in the same doctor, Heaven Canceler, on the hospital where Touma usually ends after getting hurt.
