Akai Hayate

In a shadowy world where a ruthless clan of ninjas known as the Shinogara secretly reigns over Japan, Hayate Kanuma stands as their most skilled assassin. However, a deep sense of justice compels him to turn against the very organization he serves, leading him to confront his own father, the leader of the Shinogara. In a desperate bid for freedom, Hayate takes the ultimate step and eliminates his father, marking himself as a target for his former allies.

Now a fugitive, Hayate seeks refuge in the one place he hopes to find safety—his sister, Shiori. In a moment of peril, he uses a forbidden technique to transfer his soul into her body, allowing him to temporarily harness his ninja skills through her. Yet, this bond comes with a heavy cost; each time Shiori summons Hayate's abilities, a fragment of her identity slips away. As the threat from the Shinogara looms ever closer, they must navigate the precarious balance between power and sacrifice, racing against time to find a way to ultimately dismantle the oppressive regime before it's too late.
