Keisuke

Akira's childhood friend and hard-working factory employee. He and Akira grew up together in the same orphanage. Because he is a bit weak, he has always admired Akira's strength. Though he is a bit quiet and shy, if Akira is involved, he suddenly becomes bold. Upon hearing Akira's situation, Keisuke chases after Akira and also joins Igura, despite his weakness and lack of fighting experience.
