海野 十三

Sophomore at East School. Swimming club member. He wears a samue and geta. He is a very mysterious and unique person, both in appearance and inside. He and Hajime are good friends who get along very well. They are so well matched that Asa laughs and says, "He must be a homosexual." He falls in love at first sight with Natsume, who tends to the fields near the swimming pool. [From official site]
