Kyoko Iwashita

She's a tough-as-nails, and landed the managerial job because the principal of the school hoped it would be a way to keep her out of trouble. She barely tolerates the antics of the room of adolescent boys trying constantly to get in her panties. In the episode "the Burning Spirit," she proves to have incredible motivational skills for the boys when she offers a "sex pass" to the best player on the team: "The holder of this pass can do anything they want with my body for a month!" The offer powers the below mediocre team into the city finals.
