Shigurui: Death Frenzy

Kengyou’s House of Punishment (1x10)

:

A letter arrives summoning the Kogan clan to the palace of Kengyou Shizuhata. Upon arrival, Shizuhata wastes no time in luring Gennosuke into a duel with the barbarian warrior, Sekiun. Allegedly a contest of fun and skill, the tables turn when Kogan steps in to fight in Gennosuke’s place. Sekiun, unaware of the monster he fights, strikes a blow he will regret for the rest of his life.
