Ukyo was raised as a ninja in a village. One day he stumbled upon an unconscious Eduard, and took him back. They were raised together as ninjas, along with their fellow villager Natsume. Ukyo and Eduard moved to Nagasaki, where Ukyo works as the commissioner. At some point he joined the Nagasaki Vigilante.
Ukyo has long, bright red hair which he wears in a ponytail. He has sky blue eyes and fair skin. He carries two swords worn on his left hip.
Ukyo is a laid back and free spirited individual, however he does take his work seriously. He is friendly, with most people in Nagasaki knowing him. He is always willing to help those in need or stop for a chat.
