Osamu Kurihama

Osamu Kurihara is the boyfriend of Nanako Yamazaki. Osamu is an average teenager with an afro and a thin build. He is mostly seen in his school uniform. Osamu is a kind-hearted, emotional and excitable person who is loyal to his friends but dense when it comes to matters of the heart. Nonetheless, he is hard working and treasures those close to him particularly Nanako Yamazaki (Osamu's girlfriend). He is somewhat of a coward when it comes to violence, but is willing to put himself in danger to further his relationship with Nanako.
