Iroha Tamaki, a Student in Takarazaki City, has been battling Witches as a Magical Girl. However, Iroha can't seem to remember the wish she made when she became a Magical Girl. One day, she hears a rumor from another Magical Girl, Kuroe, that Magical Girls can be saved if they go to Kamihama City. During a battle with a Witch, Iroha unexpectedly finds herself in Kamihama but…

Ai decides to disappear in order to free Sana. Alina is infuriated by the destruction of Endless Solitude and goes into full attack mode against Iroha and her friends. They find out that the Magius have been using the Uwasa's territory to confine and raise Witches. Iroha and company fight an uphill battle, but Mami and Mifuyu appear on the scene to put an end to Alina’s rampage.

Yachiyo and Kuroe find Iroha inside the Labyrinth of the Uwasa of the Eternal Sakura. However, Yachiyo and Kuroe are swallowed by the Doppel of Silence that suddenly appears from Iroha’s body. When Yachiyo awakens, she finds herself at Mikazuki Villa eating breakfast with Tsuruno, Felicia, Sana, and Iroha, but Kuroe, who is not supposed to be there, is in the room with them. Yachiyo and Kuroe are baffled by the situation they are in, but they have a hunch that they are not in the real world, but in a dream world being shown to them by the Doppel of Silence. They are concerned about Iroha’s safety in the real world, so they do all they can to wake up Iroha in the dream.

Iroha grieves about the battles that have been fought so far and figures she couldn’t save anyone in the end. Kyubey thanks Iroha and says that her hope caused everyone to fall into despair. The despair of Magical Girls is what Kyubey has been seeking all along. All the while, Iroha’s Doppel continues tormenting her. As a result of Iroha’s interference with the Magius, more Witches will be born. On the brink of despair, Iroha hears a familiar voice call out to her.
