Madoka makes the decision to become a magical girl and wishes to prevent all witches from coming into existence. By doing this, Homura returns to a world where Mami and Kyōko are still alive while only Homura remembers Madoka existed. She and the other magical girls continue to fight against wraiths formed from the negative emotions of humanity, but thanks to Madoka's efforts, magical girls are purified and disappear instead of becoming witches.
