A ronin movie directed by Irie Yū 入江 悠.

Kyoto, 1461. On the eve of the Onin War, the capital is a city in collapse. Famine and plague have claimed tens of thousands, with the dead lining the Kamo River, while human trafficking and forced labor thrive under the noses of a ruling class more interested in decadence than duty. Amid this backdrop, a lone ronin named Hasuda Hyoe moves through the chaos. An outlaw by choice, Hyoe relies on his skill and cunning to navigate a broken society—burning down checkpoints, killing corrupt officials, and gradually attracting a ragtag band of drifters and misfits. Among them is Saizo, nicknamed Frog, a starving youth with raw talent in staff combat, whom Hyoe trains into a formidable fighter.
Together with a sword master, a giant with an iron club, and a Korean archer, they plot an uprising against the shogunate.
