Kazusa Shinji

Hajime's close friend. He is Hajime, Hikari, and Ikuto's childhood friend. He loves big breasts and will indiscriminately stare at them and get excited. For that reason, he acts affectionately towards Uta. He is good at sports and a member of the tennis club, but he visits the handicrafts club, mainly to see Uta. His looks are unexpectedly good and he is cheerful, but since he often says stupid things, he has never had a girlfriend.
