Dochinpira (1992)

"Minami of the West, Thug of the East!"

Kaito Jin is a lone wolf who rules the streets of Roppongi without allegiance to any gang. Known for his charm and defiance, he often clashes with the Haozakura-kai yakuza gang. Things take a turn when he meets Masami, the niece of the gang’s boss, and finds himself caught in their world. As tensions escalate, Jin grows close to Suzuhata, one of the yakuza members persuing him, who reminds him of his dead young brother and becomes his unexpected ally. But then Masami is now dangerously obsessed with Jin, and the consequences of his entanglements come to a head.
