Azusa Hamaoka

She is a third-year at Oumi University and is a part of the intercollegiate diving club with Izu University. Known for her very outgoing and exhibitionist personality, she displays particular friendship/comradeship to Iori.

She mistakenly believes that Iori is bisexual, and admits to him that she "goes both ways" as well.

She offers to have sex with Iori in order to get him over his awkwardness of sleeping next to Nanaka and herself during the Okinawa trip.
