Jukai

Jukai is the oldest member and presumably an old man with a very raspy voice, although his face is never seen and little is known about him. He is wrapped from the neck down in a straitjacket with a spiked back, and wears a mask with a stylized number six on it. His specialty appears to be manipulation of hydrogen/oxygen particles in the air around him, as seen when he teleports Hazanko to the Leyline's gate. He attacks by turning into a giant whirlwind, appearing to be made of water, and ramming into his opponents. When defeated by Aisha at the Leyline, he deflates like a popped water-balloon, streams of liquid spurting from his many wounds. Though his arms and body are pretty much restrained in the jacket he can still cast spells by shaking his body from side to side. He appears to be Hazanko's right hand man and the strongest spellcaster other than Hazanko himself.
