Yuu Kurumeno (久留米野優) is the president of the theater club at Zashono Academy.
Like Kirika Misono she has a habit of forcing people to join her club. Due to forcing them to signing an iron clad contract they are forbidden from leaving until they can surpass Yuu in acting talent. She was forced to let Densuke Mifune out of her club after she made him join when he received a standing ovation when he was forced to act like a girl, which he can do disturbingly well.
After releasing him from the club she told him she was in awe of his ability, and naturally develops feelings for him.
