Mahou Shoujo Madoka Magica

When a new girl joins her class, Madoka Kaname thinks she recognizes the mysterious, dark-haired transfer student from one of her dreams…a dream where she is approached by a catlike creature who offers Madoka an opportunity to change destiny. Madoka had always thought magic was the stuff of fantasy…until she sees the transfer student fighting with the very cat being from her dream! And just like in Madoka’s dream, the cat gives her a choice. Will Madoka become a magical girl in exchange for her dearest desire? What will be the cost of having her wish come true?
