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.
