Seiya Hoshikawa

Seiya Hoshikawa (星川 聖夜 Hoshikawa Seiya) is Haruka Shinozaki's classmate who is a handsome, if narcissistic, boy who enjoys the romantic attention of nearly every girl in school. However, Hoshikawa is only interested in male-to-male relationships, especially with Haruka, who naturally fails to notice the deeper significance of Hoshikawa's allusions.
