Hi, Today I am going to pick the anime "Kore wa Zombie Desuka?" a Harem Shounen Comedy about Aikawa Ayumu a high school boy that is resurrected as a zombie after being killed by a serial killer, a bad day right ? but It gets even worse he is forced to become a mahō shōjo.
Based on a novel by Kimura Shin'ichi.

Description:
Life—or undeath?—isn’t easy for Ayumu Aikawa. A seemingly normal high schooler, he is in fact a zombie who serves as a bodyguard to an introverted necromancer. But his already complicated existence becomes even more outlandish when he accidentally steals the powers of a magical girl, transforming into one himself—complete with frilly dress and pink chainsaw!! How’s a reanimated corpse supposed to keep his head on his shoulders with roommates like these girls around the house?
