Kazuki, Izumiya

泉谷和樹

Izumiya Kazuki is Hirosuke's school friend. In the summer, he works at a flower shop (and wears a straw hat when delivering flowers to customers).
Kazuki is quite busy dating various girls but has had no lasting results so far. Kazuki encourages Hirosuke to confess his feelings to Yasuna, but he also persuades him to join a four-way date with two "college girls", one of whom is Suzue.
