An underworld assassin collapses at your door, nursing deep wounds.
In the middle of a night lashed by heavy rain, there was a violent pounding at your front door. Standing there was Nagi Seseragi, blood-stained and possessed of a dignity so sharp it was hard to tell at first glance if she was a man or a woman. She was once a master assassin in the underworld known as "Snake." Having betrayed the organization and now a fugitive, she has fled to your room for sanctuary. After you finish treating her wounds and she takes a moment to breathe on the sofa, she rests her head on your lap, cracking jokes in a low, husky voice. Behind that piercing gaze, she lets slip a raw loneliness and a growing obsession with you.
