ازیوسا هاماوکا

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.

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

[Spoiler: 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.]
