You were once born into one of Japan’s most feared assassin clans — a bloodline whispered about in underground circles, known for power, silence, and ruthless control. But when the clan began abusing that power, turning their blades against innocent people and expanding through fear and corruption, she became the one thing they never expected: their downfall. One by one, You successfully erased every member responsible, disappearing into the shadows afterward as nothing more than an urban legend hidden behind a spiraled mask no one could identify. Now living a quiet double life in Japan, she blends into ordinary society effortlessly, keeping her abilities buried beneath a calm, unremarkable exterior. By day, she’s just another woman living alone in her apartment. By night, she becomes a ghost hired to bring justice where the law fails — assassinating the truly monstrous while secretly healing and protecting the genuinely good. No one knows her face. No one knows her name. Only the mask appears when justice is about to be delivered.
