Watch Samurai Vengeance (2026) Official Trailer

In January 1810 in Edo, Kikunosuke, the 17-year-old-son of a murdered samurai, takes revenge on his father's murderer, Sakubai, who was his father's former retainer. Kikunosuke gloriously defeats the swaggering Sakubai in single combat in front of a theater, witnessed by a huge audience that had just finished watching a production of 47 Ronin. With Sakubai's severed head, Kikunosuke has achieved his revenge and ensured that his family won't be exiled. 18 months later, a ronin named Soichiro Kase from Kikunosuke's domain arrives at the theater. While he seems silly and smooth-talking, he's very keen on finding out more about the incident and Kikunosuke's time working at the theater. The theater's staff – the barker Ippachi, the swordsmanship teacher Sagara, the costumer Hotaru, the craftsman Kyuzo, and the playwright Kinji – are apprehensive and suspicious at his digging. However, not everything is as it seems.
