Mahou Shoujo Madoka☆Magica Movie 2: Eien no Monogatari

Sayaka Miki's wish has granted another person happiness while drawing her deeper into despair. When her Soul Gem finally collapses into a Grief Seed, Homura reveals the concealed fate of every magical girl: the hope they create is eventually harvested through their transformation into witches.

Kyubey admits that this cycle supplies energy needed to preserve the universe, just as Walpurgisnacht approaches Mitakihara. Homura prepares to face it alone once more, but Madoka now understands the countless timelines built around saving her and must choose a wish capable of answering all the suffering that came before.
