Kirikaze, a steadfast ninja of the Fuma Clan, engages in covert wars against rival factions. When the Fuma Rebellion erupts, he confronts the insurgent New Fuma Clan—traitors aiming to dismantle their ancestral leadership. Teaming with allies Shoryu and Ryuho, he battles to quell the uprising but falters in unmasking its elusive mastermind.

During investigations, Kirikaze trails Raien, a Shinsei Fuma operative, into the clan’s sacred temple. There, he unearths a pivotal secret exposing the rebellion’s architect, triggering a clash that exacts a steep personal toll.

The insurgent leader, Shimon, manipulates allies through mental enslavement, fracturing the clan from within. Kirikaze’s resolve aids the resurgence of exiled leaders Kojirou and Ryoma, who reenter the fray to dismantle Shimon’s schemes. The conflict crescendos in a brutal final confrontation against the New Fuma forces, leaving many fallen but securing the clan’s fractured unity.
