Gentlu's Trap! Yui and Ran Stuck with a Test?!

Synopsis

Out of the blue, by student council president Amane's initiative, an aptitude test is held. With the condition that anyone scoring below 40 will go to a make-up session, Amane herself hands out the answer sheets, but the questions are so hard that Yui and Ran end up with failing scores. After school, Gentlu appears in town. Kokone and Rosemary rush to the scene, but Yui and Ran are stuck in make-up classes with a mountain of tasks they must finish, unable to leave school. With help from Takumi, who comes by, Ran and then Yui finish the make-up work, but talking with Takumi, Yui realizes that, up to now, the Ubauzo have never attacked the townsfolk. Precious, together with Spicy, purifies the Ubauzo and joins Yum-Yum, who had been pursuing Gentlu. Pointed out for trying not to hurt the townsfolk, and asked by Precious "you don't really want to do this, do you…?", Gentlu's heart wavers and she suffers. The mask cracks, and the face revealed beneath is Amane's.
