Ayumu has no pulse and very little luck. Instead of dying (again), Ayumu became the world's first magical girl zombie.

Ayumu Aikawa is a 16-year-old high school student who is tragically murdered while investigating a suspicious house. However, he soon awakens next to a strange armored girl called Eucliwood Hellscythe. She reveals herself to be a necromancer who has revived Ayumu, consequently turning him into a zombie. Now immortal, Ayumu sets out to hunt down his killer. One day, while searching in a cemetery, he encounters a boisterous young girl named Haruna, who is fighting a bear with a chainsaw while dressed as a magical girl. After she kills the beast, Haruna attempts to erase Ayumu's memories of her, but he instead absorbs her magic for himself. Stripped of her powers, Haruna now orders Ayumu to take up her role of hunting strange creatures known as "Megalo," monsters that roam the human world and terrorize the population. Kore wa Zombie Desu ka? follows the daily antics of the human-turned-zombie Ayumu as he begins his new, ludicrous life where the supernatural becomes the norm.—MAL Rewrite

Ayumu was murdered by a serial killer and resurrected as a zombie by a cute little Necromancer. Then he got mixed up with a magical girl and a vampire ninja. With a harem like this, Ayumu could end up even deader before figuring out who killed him.—Crunchyroll

Some guys have no luck-he's got no pulse. The now unfortunately undead Ayumu was murdered by a serial killer and resurrected as a zombie by a cute necromancer. Things were going alright, even after she moved in-until a magical girl in a pink dress with matching chainsaw cut his rotting carcass in half. Now, thanks to magic, Ayumu is donning the pink getup as the world's first magical girl zombie. But between voluptuous vampire ninjas, hideous crayfish demons, and more chaos, Ayumu may never rest in peace again.—Funimation
