Ichiro Hanazono

Ranmaru's best friend and partner. They graduate together and are assigned to the same commander. They can be some troublemakers when together. Ichiro often calls Ranmaru a pervert and says that he has something for his younger sister. In actuality Hanazono has a crush on Saya and often gets mad at Ranmaru for always being around attractive women, stating that he used to think Ranmaru was loser.
