Yamada-kun to 7-nin no Majo Episode 8

Yamada and the club try to gather the seven witch girls in order to conduct the ritual that will grant them a wish. At first, only half of the girls agree to do it, but the others eventually join. During the actual ritual, Saionji feels chilly and wishes for panties, but that becomes the final wish, and that they won't have another chance until the next year. They come up with an idea: Yamada can get the witch killing power by kissing the president, and cancel all the powers. However when he kisses Saionji, he will forget everything concerning the witches. He decides to do it anyway. Shiraishi feels sad that he does not remember but realizes she loves him so she confesses to him. He ignores her but she follows him and they fall down the stairs. Yamada begins to remember and finds Shiraishi and they kiss.
