Zeru

是流

Zeru is the "Captain" of Jolly Devil Six. His power revolves around fire (火炎術), and his only attacks are Fire Aura and a fire blast. He seemingly punches Hiei through the stomach, then shoots a fire blast at him, again seemingly killing him. Then Hiei appears behind Zeru, stunning him because he does not realize that a fire-based attack will not work on other fire demons. Thus, he is killed by the infamous Black Dragon Hell Fire (Jao Ensatsu Koku Ryu Ha) (referred to as Dragon of the Darkness Flame in the English version). Upper C class demon.
