Originally one of Rokudou's many bullies, Tsubaki is Iinuma's girlfriend. After she falls under the spell of Rokudou's powers, she becomes remorseful for the way she treats him, and apologizes to him while in the bathroom. Her attention to him draws the initial ire of Iinuma, though after the two become friends, Tsubaki regularly hangs out with Rokudou and his friends. She does not react to Rokudou's power anymore.
