At one point, she met Tamao Oguro, daughter of Knuckleduster, and possessed her body, becoming her new host.[1]

Since then, Kuin lived as a simple high school student, while doing assignments and jobs for the leader of the Villain Factory: In general, her job was to distribute Trigger through the streets, collect data from those that had been transformed into Instant Villains for the drug, and look for suitable candidates among these consumers to kidnap and transform into Next-Level Villains.[2]

To survive, Kuin looked for a house and murdered his owners, using their corpses as food and hives for her bees, while she used the money from their credit cards to live, until the money ran out, at which point she left the place and looked for another family.[3]

The Instant Villains are quickly subdued by the Heroes. Kuin met up with Teruo Unagisawa while the attack was taking place and suddenly starts bleeding out of her eye because someone squashed one of her bees. Teruo and Kuin then continue to walk into a back alley.[4]

Later as Kuin is shopping, her Trigger supplier calls and tells that she should pick her targets more carefully, focusing on those with strong wills and potential. That night, she offers Trigger to a drug addict and encourages him to use his enhanced power, which he does by trying to smash her, but she dodges the strike and continues encouraging him before leaping away.

The next day, Kuin is sitting in a cafe and on the phone with her supplier. She questions if they should take care of the three vigilantes that keep interfering, but the supplier points out that they receive real battle data without involving Heroes or the Police Force. After the call, Kuin is approached by a man, who asks if she is "Honey." Complimenting his appearance, she takes him by the hand and leads him outside.[5]
