Rokesh

ロケシュ

Rokesh is the ruler of the Naga Raja Tribes of the Abelion Hills and one of the demi-human tribal leaders that participated in the invasion of the Roble Holy Kingdom commanded by Jaldabaoth. He was a demihuman that looked like a snake that had grown arms. The scales on Rokesh's body gleamed wetly, throwing off a bizarre riot of colors that did justice to its nickname of "Rainbow Scales".
