Season 1

Season Overview

The Shinogara are a secret assassination organization that has controlled Japan from the shadows for centuries. After its leader Tanzō Kanuma is murdered, his son Hayate is branded the killer and flees with his sister Shiori and friends Ikkaku Date and Shuri Satomi. Fatally wounded, Hayate transfers his soul into Shiori's body, allowing her to summon the power of the Shadow Armor in battle—but every transformation erodes her own identity. As the treacherous Genbu Kurama seizes control of the Shinogara, the siblings must expose the conspiracy and face the final battle before Hayate consumes Shiori completely.
