The Era of Valor and Nobility

The venerable Yakuza Hotoke no Kisaburo tries to eliminate the corrupt boss Tsukuda, but the intervention of the young judoka Tsuzaki foils the plan. Tsukudu survives and plots to take over the city's water supply project. A wandering karate student, hostile to both Tsukuda and Tsuzaki, intervenes in the situation, which turns the conflict into a triple-confrontation chaos.
