Fan Casting Naga in Beelzebub (Live Action J-Drama/Web Series)

Naga is first introduced with Graphel when the latter attacks Izuma and Tojo, but maintains a detached attitude that contrasts with Graffel's violence. He rushes with Graphel to Hecadoth's aid against Saotome, only to be dispatched to the demon world by the teacher. It is later revealed that he is known as the Water Dragon King and his power is way above Hecadoth's and Graphel's. His black aura often takes the shape of a dragon. He is probably named after the Hindu deity.
