He often expresses admiration for Kazuya’s girlfriends, openly appreciating their physical appearance and charm.

Like Kibe, Kuribayashi enjoys teasing Kazuya, especially about his love life. He does not shy away from voicing his attraction to beautiful women and is straightforward about his preferences, often making light-hearted or enthusiastic remarks in their presence.

Shun Kuribayashi is a college student of average height and slim build. He has ear-length blonde hair, narrow eyes, and wears thick-framed rectangular glasses. His eye color varies slightly in different illustrations, appearing either light or dark. One of his most noticeable features is his prominent front teeth, which add to his distinctive look.

Kuribayashi typically dresses casually, often seen wearing plain pants and a T-shirt, paired with a checkered shirt or a light jacket layered over it.

Shun Kuribayashi is first introduced early in the Kanojo, Okarishimasu series as one of Kazuya Kinoshita’s close college friends. He appears during a group outing where Kazuya introduces Chizuru Mizuhara as his girlfriend. Like the others, Kuribayashi is stunned by Chizuru’s beauty and becomes curious about their relationship. Unaware that Chizuru is a rental girlfriend, he initially believes the two are genuinely dating.

Throughout the series, Kuribayashi appears in various scenes involving Kazuya’s friend group. Though he is not heavily involved in the central plot, he contributes to the group’s dynamic by offering comedic commentary and reacting to Kazuya’s increasingly complicated love life. He often expresses envy or admiration toward the women around Kazuya, especially Chizuru.

Kuribayashi continues to support Kazuya as a friend, though he occasionally joins Kibe in teasing or scolding him, especially when Kazuya’s behavior becomes questionable. Despite his limited screen time, Kuribayashi remains a consistent background presence in the series’ social and comedic moments.
