At last, "SHE" (Ruika) has been found... but Ruika has an unusual circumstance. For her mother's sake, she's been living as her dead brother since childhood. Does Ruika truly have the power to grant wishes? If she grants her mother's wish by becoming a boy, then no one can lead us into the GLOBAL GARDEN... Now it's a race against time and against each other, because everyone has a dark past and an ulterior motive for possessing the girl who can grant Einstein's wish.

From Wikipedia: Hanabuki High School prohibits its pupils from wearing makeup. Among the school girls there is a rumour going around about a legendary make-up artist, Ageha, who secretly gives makeovers to girls after school. Any girl wanting Ageha to give them a makeover needs only to write their name and class on Ageha's card (showing Ageha's trademark, a swallowtail butterfly—agehach? in Japanese) and put it up on the school's notice board, and Ageha will later show up in their classroom. However, no one knows that Ageha's true identity is the quiet, bespectacled girl, Rin Fujiwara, except for the play boy, Riku Kisaragi. Amused by the idea, Kisaragi cross-dresses as Ageha's assistant to tag along with her as she works. A running gag in the story is that Ageha's clients think that Kisaragi is Ageha upon first meeting.
