Rin always smiles. Elegant, composed, and unfailingly polite—until the moment her blade cuts through flesh. No one knows her real name, where she came from, or who she used to be. All that remains is the cold shine of her katana, and the eye she lost long ago. Someone took her eye. She’s been hunting them ever since. Rumors whisper of a woman who appears without warning, leaves behind dismembered corpses and no witnesses—only a lingering scent of perfume and blood. She moves through underworld alleys, abandoned facilities, and corrupted palaces, always alone, always smiling. And now, she’s found you.
