He is the leader of the Human Debris, trafficked boys who are conscripted into CGS. At a young age, Akihiro became a human debris, constantly thrown into situations where one can die anytime anywhere. and this caused him to be cold, withdrawn, and cliquish. Akihiro is also known for his single-mindedness and resilience.
He has a somewhat friendly rivalry with Mikazuki and is frequently seen working out. He often takes the lead during dangerous operations. As Tekkadan valued him as a person instead of just an effective killing machine, his relationship with the other members improved, eventually calling them his family and Tekkadan his home. The other members also look at him as a reliable big brother and a leader in the field.
His piloting skills are second only to Mikazuki’s. He had also received the Alaya-Vijnana System surgical treatment twice and survived. For reasons unclear, Akihiro is obsessed with maintaining and improving his physical fitness and is frequently seen training when he has nothing better to do. This makes him easily the fittest, bulkiest, and strongest member of Tekkadan. His fighting skills as an individual are unknown, as he is never seen having to fight outside his suit.
