Two skilled soul hunters cross paths with Death City, unaware their quiet precision is about to pull them into the world of meisters, madness, and fate.
At Rasetsu Academy, where Oni are trained to master their blood and survive a world that fears them, a new teacher quietly joins the faculty. Known only as Y/N, she is calm, unreadable, and vastly more dangerous than she lets on. Assigned to Mudano Naitō’s class, her presence begins to shift the balance—challenging the students not just to grow stronger, but to confront what it truly means to be Oni in a world built to destroy them.
A century after her capture, Y/N—a legendary assassin believed dead—awakens from forced hibernation inside a corrupt scientific regime. The world outside has evolved into a cold, futuristic age, where assassins exist only as a secretive convent and Y/N’s name survives as myth, scripture, and warning. As the scientists scramble to contain what they never truly killed, the convent realizes the truth: the past’s most powerful weapon has returned—not by chance, but because the world has finally reached the moment she was meant for.
In a forgotten Section 8 complex known as The Heights, cut off from the city and watched too closely by the wrong eyes, an aging woman becomes the quiet center of a community shaped by poverty, discrimination, and violence—holding together eight lives that survive not because the world is kind, but because they are.
Long believed to be nothing more than myth, the Veilbound Covenant has protected the balance of the world from the shadows for centuries. They erase threats—and themselves—before history can notice.
