Love triangles, quirky situations, and the art of juggling several romantic interests are nothing new in harem anime, and several ones perfectly depict them. Here are some of the best harem anime to watch if you love 100 Girlfriends.

10 Is This A Zombie

Is This A Zombie is an unconventional harem anime filled with magic, zombies, and a cross-dressing protagonist. Ayumu Aikawa was a high schooler killed by a serial killer at the start of the anime and resurrected as a zombie by Eucliwood Hellscythe, a necromancer who prides herself as his number one waifu.

After his resurrection, Ayumu attempts to find his killer and uncover the mystery behind why he was killed with the aid of Eucliwood, a vampire ninja named Seraphim, and a magical girl named Haruna while battling demons known as Megalos.

9 Rosario + Vampire

Like the last entry, this anime also features supernatural elements, although it is a romantic comedy. Rosario + Vampire revolves around Tsukune Aono, a teenage boy who enrolls in a particular boarding school due to his inability to get admitted, except the school was initially established for monsters only.

A vampire girl, Moka Akashiya, befriends him and becomes obsessed with his blood, kickstarting a relationship with him. Several other monster girls are also thrown into the mix as they develop feelings for him, creating a pretty complex situation.

As expected, they all start developing romantic feelings toward him, making his task a little more complicated than it should be. The girls must also confront their feelings as they work with Nariyuki to achieve academic excellence.

6 Oresuki: Are You The Only One Who Loves Me

Oresuki tells the story of one of the best and most complicated love triangles in harem anime. Amatsuyu Kisaragi, also known as Joro, crafts a plan that involves setting up his best friend Sun-chan with either one of Cosmos or Himawari while he tries to date whoever is rejected.

However, the situation gets very complicated when Sumireko Sanshokuin confesses to Joro, and she happens to be the girl Sun-chan is in love with. Her introduction into the fray complicates Joro’s plans and creates many comedic situations between all the characters involved.

5 Girlfriend, Girlfriend

Also featuring a love triangle, Girlfriend, Girlfriend tells the story of Naoya Mukai, who is put in a tight spot shortly after he begins his relationship with his childhood friend, Saki Saki. Nagisa Minase, a classmate of his, confessed her feelings to her out of the blue, and after a few minutes of consideration, he agreed to date her.

Naoya lives alone, so his two new girlfriends decide to move in with him. Balancing two separate relationships takes work, and Naoya found out the hard way.

4 Rent A Girlfriend

Getting a girlfriend can be just as easy as renting one, which is the route young Kazuya Kinoshita takes when his ex-girlfriend, Mami Nanami, breaks up with him. The situation with his rented girlfriend, Chzuru, becomes more complicated when he discovers they are next-door neighbors attending the same college.

3 World’s End Harem

World’s End Harem features a more futuristic setting where society has been altered drastically by the effects of a virus that resulted in the deaths of nearly all the men on Earth. Reito Mizuhara wakes up from his cryostasis after five years to find the world different than he left, with only one million men surviving the catastrophe.

Reito and four other men in Japan are expected to participate in a breeding program where they procreate with several other women to repopulate the country gradually. At the same time, he searches for a close childhood friend with whom he had romantic inclinations before his cryostasis.

2 Monster Musume: Everyday Life With Monster Girls

Life with monster girls is not as fearful as it sounds, and Kimito Kurusu is living proof after accidentally getting into the Interspecies Cultural Exchange program, which pairs liminals (the monsters) and human hosts together. However, some rules come with the program, mainly to prevent procreation or violence between both species.

However, Kimito somehow ends up accommodating only female liminals, which starts developing romantic feelings toward him and puts him in numerous comedic and wacky situations. Things get even more complicated when a rule change sees him expected to marry at least one of the girls.

1 The Quintessential Quintuplets

The Quintessential Quintuplets features a similar premise to the series We Never Learn: Bokuben. Futaro Uesugi, a genius, has to tutor quintuplets sisters of the wealthy Nakano family to make ends meet due to his humble background.

Although they start on the wrong foot and have no passion for studying, he slowly but surely worms his way into their hearts and convinces them to put effort into their studies. They all fall in love with him as the story progresses, and it is later shown in a flash forward that he ends up marrying one of the sisters, but her identity is still hidden…for now.
