if i had to describe "Kore wa Zombie desu ka?" in one word i would simply say cringe: a "plot" that doesn't exist combined with terrible characters, but let's go in order.
Aikawa Ayumu is a normal high school boy who one day is murdered by a serial killer, he will be resurrected by a magician who will turn him into a zombie.
and here begin the first problems: our protagonist, already uninteresting because of his flat and not very charismatic character, will join a necromancer who can not speak, the only good thing about the series is her backstory, but all it is ruined by a knight costume for the necromancer that ruins a character that could also make sense in this series without sense. but that's not all, in fact our protagonist steals powers from a mahou shoujo (WHY?) who will be forced to train him as a future mahou shoujo to fight the Megalo agency instead of her, this will create a series of embarrassing situations that are not funny, and that will make you wonder why you watched this anime. And yet it's not over (it's a nightmare) because the vampire nija Seraph appears and through a series of predictable and nonsense jokes she will make us regret to be born, but he has big boobs, to attract an audience of people who are only interested in butts and boobs, but that’s not the end: in fact the cats present Yuki Yokishida , she too is a vampire ninja but opposite to Seraph, needless to say that she is only able to make useless and incomprehensible jokes that seem invented on the spot. There is also mythology in this terrible show, in support we can find Cerberus: a three-headed dog dressed in a suit and tie who works as a detective (WHY?). basically this series doesn't only suck, it's also scary for how useless and meaningless it is, useful only to those who want to regret the good shows. so, don't watch it if you want to preserve your mental health. but if you are interested in boobs and asses watch it, they are great, but if you want to watch a good anime please ignore it, I don’t know why this show has a such good score but that’s not real: if you want to preserve your mental sanity drop this anime. And if you want to ignore the plot, the character design, and the music, that’s ok: I will not judge you for watching anime just for boobs but, instead of this garbage watch a good hentai.
