Uchida Makoto calls out a girl who he fell in love with, Kittaka Ayame, to the school rooftop and confesses his feelings to her. However, she bluntly rejects him and quickly walks away. As he’s lamenting his timidness and inability to convey his love properly to her, another girl shows up and says that she is a witch who will help him by using magic.
Actually, she is his senpai Tomomori Yuumi. She brings him to the gym storage room and gives him a bag. Inside are a wig, ribbons and girl’s seifuku and underwear. She gets him to reluctantly dress up as a girl and brings him to the light music club which Ayame and her are a part of. She introduces him as Mishiba Kotono, the new keyboardist for the club. Will this little bit of ‘magic’ help him get closer to Ayame? What happens if his cover is blown?
