It began publication in July 2012 in the manga magazine Weekly Shōnen Champion, published by Akita Shoten, and has been compiled into sixteen tankōbon volumes as of September 2017[update].

Things turn from bad to worse when a strange-looking girl arrives and massacres almost everyone in Kogami’s class, reanimates them, and begins to take over the rest of the world alongside her minions.

Luckily for him, Kogami manages to escape the building along with his childhood friend Tsukune, and teams up with the rest of the survivors to stop the mysterious figure’s plots to end humanity, and the world.

[1] Also reviewing the series for Anime News Network, Rebecca Silverman gave the first volume a grade of B+, stating that the reader is "constantly lulled into a false sense of knowing who the survivors are and will be ... keeping everyone perpetually on edge."

She was critical, however, of the series' fan service, writing "to say that this book is gross might be understating it a little, and that gruesome quality is made somehow the worse for the inclusion of panty shots with a carefully drawn line showing us the vulvas of the girls in question...who may or may not have whole heads at the moment of fanservice."
