The last time she closed her eyes, Glass Heart prayed that she'd be set free from the torment she'd wrought as an assassin. A year later, she awakes from a coma to discover a deep scar on her chest and memories that aren't hers. These vivid flash-backs lead the young assassin to Shinjuku and the doorstep of Ryo Saeba, the legendary City Hunter. However, it quickly becomes apparent that Ryo isn't the sweeper he once was.
