Madoka makes the decision to become a magical girl, wishing to prevent all witches from the past, present and future from coming into existence in the first place, a wish made possible by the massive power inside her. As she makes the transformation, her consciousness is greeted by Mami and Ky?ko. Becoming a god-like entity and defeating Walpurgisnacht, Madoka spreads herself across space and time, preventing fallen magical girls from becoming witches by absorbing their despair and having them disappear peacefully. Homura is taken to a place outside of time where she witnesses Madoka exterminating the witch born from her own comet-sized Soul Gem. In doing this, Madoka starts to fade into a higher plane of existence, present at all points in all spacetimes but absent from human memory and perception. Madoka leaves Homura with a ribbon so that she will not forget her. Madoka then leaves and joins Sayaka, who ultimately had to succumb to a magical girl's fate as Madoka had chosen to respect the wish she made to heal Kyosuke. Homura returns to a world where Madoka does not exist, Mami and Ky?ko are still alive, but only Homura retains memories of Madoka. She and other magical girls continue to fight against wraithes formed from the negative emotions of humanity, but thanks to Madoka's efforts, magical girls disappear instead of becoming witches after exhausting their hope. Despite being alone and facing these new enemies, Homura remains firm in protecting the city that Madoka loved.
