Aika Kiryuu/Relationships

Issei Hyoudou
Issei thinks that she is one bad influence for the Church Trio giving them pervert advices.

She appears to be a fan of the rumor between Issei and Kiba as she is shown to be encouraging it when she took a misleading photo of them together and spreading copies around school, as well as buying the Prince×Beast ‘doujinshi’ manga based off them.
