From JShoujo Scans:

Little Rin Fujiwara hated her own face a lot. It was not until her 6th birthday that a make up box she got as a present changes her perspective completely. In front of the mirror, Rin would play with the make up, which becomes like a magic that makes her stronger. Rin believes make up can change both appearance and heart, because it gives the confidence a girl needs.
Years later, Rin attends her first high school year. She decides to help other girls there to become pretty as well, using her make up box. Rin, hidden under the identity of Ageha, a legendary make up stylist, with a help from her classmate Kisaragi, who has to hide his real identity by crossdressing as a woman, is willing to do magic in front of the mirror and change girls “just like when a caterpillar transforms into a butterfly”. How to meet Ageha and have her make you more beautiful? Easy, just write your name and class on the butterfly card and put it on the bullentin board on the 3rd floor. Ageha will come for sure, so what are you waiting for?

Ageha Shiraishi has been sentenced to death, suspected of murdering her four roommates. In her prison cell as she awaits her execution, she tells her warden, Kyousuke, that she is innocent and that she did not commit murder. Kyousuke does some research, but finds that she is still guilty. Upon his return, he finds his superior tied up and stripped. After setting her free, he finds out that he has been tricked, and it was Ageha in disguise.
Ageha can impersonate anyone to the finest detail, whether it be hair color, habits, or even voice. She becomes the first fugitive of the Talsis Prison and she declares that she will find the real culprit. Kyousuke now only has one clue, which is "the Ageha" (swallowtail butterfly) tattoo on Ageha's back. The chase between the characters involved begins as they move to grasp the truth!
