Kaiou Jaku 寂海王

Jaku is an eccentric but kind-hearted individual. His offers to his opponents of working alongside him as a martial arts instructors can be seen as either a genuine request or a misdirection to confuse his opponents, exploiting that oppurtunity to attack, or possibly a mix of both.

He seems to be near solely motivated by aiding and instructing the youth of Japan to be strong people and fighters, routinely asking competitors to aid in this endeavour as martial arts instructors.
