Yoshiaki Kibe

Kazuya's friend and childhood friend since elementary school. Former captain of the karate club. He also has a close relationship with Kazuya. He has been observing Kazuya, who has had no luck with women, since the past, and when he saw Kazuya walking with Mizuhara, he suspected it was either a scam or a religious solicitation. When Kazuya declared he was breaking up with Mizuhara, he spoke about Kazuya's character and advised Mizuhara to reconsider her thoughts about Kazuya. He also gave them ferry tickets as a celebration for Kazuya getting a girlfriend. He often makes philosophical remarks, but they mostly contain dirty jokes.
