   Summary

   Muichiro doesn’t remember it— not that he remembers much of anything about his past— but when he was a child, he crossed paths with his ancestor, Kokushibo. The very demon who cursed their bloodline and ruined the lives of everyone who carried it.

   Now, after years of silence, Kokushibo has returned with a single intention: to reclaim his descendant.

   The Hashira refuse to let that happen, especially Obanai, who knows all too well what it means to be used and claimed by a demon.
