Atsushi is a kind and sweet individual who loves to help others out and protect them — especially ones who definitely need help. He tries to put others before himself, and shows that he's a worthy person in the Armed Detective Agency. Yet, Atsushi has a lack of self esteem and big trauma of his younger days at the orphanage. Atsushi is also known to turn into a white tiger, but it's very rare for him to fully transform into the tiger. He has the ability to regenerate lost limbs, but slowly.
