Shikabane Hime: Kuro continues the story from Shikabane Hime Aka, set six months after Tagami Keisei’s death at the hands of the Shichisei (Seven Stars), an elite group of Shikabane who pursue more than mere regrets. Following Keisei’s dying wish, Kagami Ouri temporarily contracts with Makina to prevent her from turning into a Shikabane. Ouri has since trained to become a proper monk so he can maintain his contract with Makina and aid her in fighting the Shichisei, who not only killed Makina and the entire Hoshimura family but have now targeted Keisei as well. Meanwhile, the treacherous monk Shishidou Akasha aligns with the Shichisei, aiming to destroy all Shikabane Hime and the monk organization that employs them.
