Ayumu has had bad luck in his life -- and after. Murdered by a serial killer, the high school student was later resurrected as a zombie by cute necromancer Eucliwood, who subsequently moved in with him. His corpse was later chopped in half by a magical girl with a pink chainsaw. Because her powers are trumped by Eucliwood's, Ayumu doesn't die again; however, he is transformed into the world's first magical girl zombie. As if that's not bad enough, there's also a hideous demon on the prowl who wants to devour Ayumu.
