Ban Yozakura

He is the grandfather of the Yozakura family and the father of Reo Yozakura. A legendary "infiltrator" who can enter and escape from anywhere. He usually stays in jail for missions of gathering information from the underworld, but he is known as a "Walking Data Leak" who will spill information about the underworld to attract women. His skill is enough to easily slip through Kyoichiro's Steel Spider. Until he met his wife, Keiko, he was like Taiyo, with no relatives, not opening his heart to anyone. But after meeting Keiko, he started to change his way of thinking.
