An excellent harem parody that needs to be watched
"Is This a Zombie?" follows the story of Ayumu and his misadventures with the supernatural. It is categorized as a harem, but it's actually a complete parody of harem stereotypes.
Seraphim: a vampire ninja (yes hat's real) with the sharpest tongue in all anime
Eu: a necromancer from Hades and the one who turned Ayumu into a zombie
Haruna: your magical garment girl
The beauty of this anime is that it purposefully follows the tropes of your typical supernatural harem, and then just destroys it. Even to the point that the anime flat out calls it's own tropes a "light novel harem"
Even better is the reaction of the characters when one of harem tropes (magical girl, accidental marriage, etc) is revealed. It is pure skepticism.
The typical reaction someone would have if they told you that they are a magical girl
Overall, my analysis is that if you want a funny anime that makes fun o the abundance of harem tropes, then this is the anime for you.
