A boy keeps a promise to a dead girl by becoming a monk, knowing it's the only way to stay beside her as she fights to stay human. The Shichisei aren't just enemies, they're a mirror of what Makina could become if she stops caring whether she lives or dies. Grief doesn't end here; it transforms into something harder to name.

Six months after the Shichisei killed Tagami Keisei, Ouri is training to become a proper monk. His reason is simple: Keisei asked him before dying to take on a temporary contract with Makina, a Shikabane Hime, so she would not decay into a Shikabane, and becoming a monk lets him keep that bond. The Shichisei, known as the Seven Stars, are a group of elite Shikabane driven by more than lingering regret. They are responsible for Makina's own death, the slaughter of the Hoshimura family, and Keisei's murder, and Ouri means to help Makina fight them. The danger does not come only from outside. Shishidou Akasha, a monk turned traitor, has joined the Shichisei, aiming to wipe out every Shikabane Hime along with the Kougon Sect that commands them. A direct sequel to Shikabane Hime: Aka, this supernatural horror series mixes action and drama across twelve episodes.
