Aika Kiryuu

Aika Kiryuu is a third-year student who is in the same class as Asia, Issei and all their friends in the same year. She wears spectacles, has gold-colored eyes and lightly messy brunette hair tied into braids on each side. She wears the Kuoh Academy girls' school uniform. She has a very perverted and somewhat mocking personality. She tends to give the Church Trio lewd advice about attempting to attract Issei. After Tosca joined, she received some advice from her too. She doesn't hesitate to also poke fun at the Perverted Trio about their lack of popularity with girls, more often now she specifically teases Issei on all the girls that like him while encouraging Matsuda and Motohama's jealousy over him. She appears to be a fan of the rumor between Issei and Kiba, buying the Prince×Beast ‘doujinshi’ manga based off them showing it to the Church Trio and Tosca. After learning about the Devils' existence - she felt ignorant of Issei and his friends, and wanted to help Asia and the others by attempting to find someone to learn magic from. She has enough confidence with the Occult Research Club and Hyoudou Residence members that she even asked some of them if she could learn magic from one of them. She shows admiration for Lavinia Reni after being accepted as her apprentice.
