Rei has no last name, no attachments, and no belief in monsters that aren't human.
In a quiet modern city, she lives alone in the same house where her past ended-doing jobs she never speaks about and surviving the only way she knows how.
Everything changes the night nine strangers appear in her world, armed with swords, speaking of demons, and clearly out of time. Rei takes them in out of caution, not kindness, unaware that they are the Hashira-pillars of a world that should not exist.
As the Hashira struggle to understand a demonless era of guns, concrete, and shadows, they begin to notice things about their host: the way she moves, the silence she carries, and the secrets she never explains. To them, she is just a guarded woman with no surname.
Until the night they follow her.
What they witness forces both sides to confront a terrifying truth-some monsters wear human faces, and some weapons were never given a choice.
