Homura Akemi returns to Mitakihara after Puella Magi Madoka Magica's finale to find the witches gone, replaced by wraiths: creatures born of human grief that drain emotion from the living. Mami Tomoe holds the magical girls together, but Sayaka Miki and Kyouko Sakura keep clashing over how to fight the new threat. Homura, carrying knowledge the others don't have about how this world actually works, moves to keep the group from tearing itself apart before the enemy does. This manga bridges the original series and the film Rebellion.
