Aiko Kudou 工藤愛子

She is an A class student and is especially good in health. In episode 2, she fights against Kouta and loses. She also likes to pick on Kouta's ability to handle girls by talking about her underwear and bra. She does this in episode 19 when the summoners avatars are saying their secrets. She also abused this in episode 16, which was easy for her to do because she was swimming at the beach with the rest of the main characters.
