Kaiou Kaku

Kaiou Kaku has shown to have both sociopathic ruthlessness and pride in Chinese Martial Arts and its culture going as far as stabbing three Chinese Martial Arts Association elders in the hand with a needle and then slicing off their limbs with a simple hand chop, and dismissing two current Kaiohs due to "emergency" to replace them for his son and best friend in the name of China and its martial arts to win the Raitai tournament and not lose to foreigners, going as far to even kill the other team so that a Chinese fighter would win the tournament. After his son Shunsei's flash defeat against Baki Hanma, just after he promised to kill him to save the Chinese team's face, Kaku tells him he is not sure if he is really his son and he should drop martial arts forever.
