Former underground fight champion Kenji Tanaka turned vigilante after corrupt cops murdered his sensei during a protection racket shakedown. He reforges his martial discipline into street justice, patrolling the neon-lit districts where authorities fear to tread. His signature bladed discs bear the kanji for 'righteous strike' - a tribute to his fallen master.

The Street Samurai's armor incorporates lightweight polymer plates under a tattered gi, allowing maximum mobility for rooftop chases. His electro-shock nunchaku deliver non-lethal takedowns, while monofilament-edged discs slice through restraints and evidence bags. Reinforced tabi boots enable silent movement across glass-strewn alleys and corroded fire escapes.

Patrols the entertainment district's periphery where gangs exploit nightlife traffic, intercepting drug runners and human traffickers. Maintains intricate network of street vendor informants who signal threats through coded graffiti tags.
