From CMX:

High school student Yukari Fujimaru knows a potential star when she sees one…because she sees the special "aura" they give off, in the form of angelic wings. Yukari's fellow student, the beautiful Ryoko Katsuragi, has a small pair of wings herself, and is one of these aspiring talents. She's so talented, in fact, that no one even knows that "she" is actually a boy in disguise. Now, to make her own down-to-earth dream come true, Yukari must help her new friend become a star.
