Guugaku is a tall man with long arms and legs. He has no hair and carries a large sword.
Guugaku acts as the point-man of the group and as such, he's usually the first to volunteer to fight the Kei Pirates' enemies.
Guugaku uses Tao magic to deal with his enemies. As the point man of the group, he specializes in Tao spells that are offensive in nature. He is able to fuse his minions together into a makeshift platform to ride on and pursue a car at an undetermined speed, and generate large and powerful energy blasts. For protection, he can also produce defensive barriers rendering most conventional weapons useless on him. As a result, it was only through using a No.3 caster shell that Gene was able to kill him.
Aside from Tao magic, Guugaku's weapon of choice is a large sword which he wields skillfully. He also acts as the controller for the Soi Len's pirate ship.
