Obanai's mouth is usually hidden by the bandage he wears over his lower face to hide his large facial scars, which were the result of his family horrifically cutting open his mouth to resemble that of a snake's gape.

Obanai is a young man of short stature, pale skin complexion, and a fairly muscular build. He has straight-edged black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones. His right eye is yellow and his left is turquoise.
