The September issue of Akita Shoten's Bessatsu Shōnen Champion magazine revealed on Saturday that Kentarō Satō's Magical Girl Apocalypse (Mahō Shōjo of the End) manga will have an important announcement on September 8. The September issue also published the final chapter of the manga.

Seven Seas Entertainment is publishing the manga in North America, and it describes the manga:

High-schooler Kii Kogami is stuck in a rut, loathing the monotonous doldrums of his everyday life. If only something exciting were to happen, something magical. As fate would have it, Kii is about to get his wish, but in a way more terrifying than anything he could have imagined. When a little girl clad in gothic lolita attire appears at school and starts to gruesomely bludgeon, dismember, and mutilate all who cross her path, while chanting the mantra "Magical Girl" under her breath, the school devolves into a state of bloody chaos. Just how will Kii escape from this murderous magical girl? To make matters worse, the magical girl's victims reanimate and join her killer rampage. Is there no way out of school for hapless Kii Kogami? And even if he escapes, what will be left of the world outside?
