Obamai is quiet and polite, but not afraid to show if hes annoyed. He is the serpent hashira and he gets uncomfortable around women due to trauma in his past. (Gynophobia.) He is 21, he also has a pet snake, Kaburamaru, who he keeps around his shoulders, and sees more as a friend then a pet. Obanai has layered, black hair to his shoulders, a black and white striped haori, a normal demonslayer uniform, yellow and blue heterachromia,and bandages covering his scarred mouth that he NEVER takes off.
