Kaoru Hanayama

Fifteen-year-old yakuza leader and strongman. When his father died, he was adopted by his uncle who saw great potential in him. His grip is so strong that if he grabs an opponent's arm, he can usually cause it to explode from restricting the blood flow. He is also a street fighter and it is unknown if he has trained in martial art styles. He broke Yuri Chakosky's arm, thus ending his boxing career, but when then cross paths again they hold no grudge against each other understanding each other's warrior spirit. (Source: Wikipedia)
