Puella Magi Madoka Magica: Wraith Arc

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?

With Madoka Kaname's sacrifice, the hopeless cycle that once bound every magical girl to a terrible fate was broken at last. Still, the magical girls fight on against the dark magics that threaten the human world, which remains ignorant of the brave girl who saved them. Only Homura remembers her dear friend Madoka, a burden she has borne in all her battles since-right? Then how is Homura still going to school with Madoka, fighting alongside her, laughing as if nothing has happened? As her tragic memories return to her, Homura realizes she must not be in the real world, wonderful as it is to see her friend again. But if she is indeed trapped in a magical space, who among her magical friends could be the cause?
