Tsuyoshi Seino (Japanese: 清野毅) is member of the Mad Angels gang that operates in the New Yokosuka Harbour District. Originally he used to work in a factory, but found the job too boring to put up with, so quit and lived off gambling for a while. But soon he found himself with deep debts so, feeling he could no longer lead a normal life, offered his services to the gang.
