Yujiro is a very cruel and arrogant man. He shows no mercy towards anyone, seeing mercy as a "weak" trait. He loves to fight and destroy anything and everything he can. His entire life and mentality is dedicated to nothing but fighting and getting stronger with each person he defeats, sometimes killing them. He tends to kill people if pushed or enraged enough, and shows no care or remorse in doing so. He will also kill for pleasure or satisfaction. He has a deep resentment for the weak.
