Kuin's personality was a fusion of Tamao Oguro's and the swarm of parasitic bees that had infiltrated her brain. Kuin appeared to be a cheerful girl who was described as strange by her own friends. This cheerful attitude was, however, nothing more than a façade. In reality, she was a ruthless villain who did not seem to care about the destruction caused by the victims of her bees. She was also extremely manipulative and enjoyed toying with the emotions of her potential victims. She seemed to be very fond of her bees, which she called her "babies."

By utilizing Trigger, she sacrificed some control over her host body in order to achieve more strength, giving Tamao Oguro back some control.

Getting the role of Kuin means that you'll get a good amount of lines as you will be the main villain for the first arc in the series!
