1. Kono Subarashii Sekai ni Shukufuku wo! (KonoSuba: God’s Blessing on this Wonderful World!)
Kazuma Satou is a NEET, meaning he spends his days playing video games at home, rarely venturing out. It all starts with his untimely death and a decision from a goddess named Aqua in Kono Subarashii Sekai no Shukufuku wo! Either he goes to heaven or he begins a new life in a make-believe universe. It’s doubtful that Kazuma’s decision to go with option two will prove to be the best one. When he is given the option to select one item to help him with his future questions, he opts for Aqua instead. It’s a shame she’s powerless to stop it! What hope do the two have of defeating the demon king, or will they be stuck in a never-ending struggle just to afford food and rent?
The relationship between the main characters is the most striking similarity between Kono Subarashii Sekai no Shukufuku wo! and Monster Musume no Iru Nichijou. Like Kimihito and his harem of girls, Kazuma and Aqua are members of different species. In the same way that Kimihito learns about his girls one by one as his partnership develops into a romance, Kazuma must also adapt to the differences between him and the goddess, even though he only has to deal with one rather than many different kinds of monsters.
While Kimihito’s world is technically Japan, it’s not the Japan we know today and it’s also full of monster girls! Kazuma also lives in a fantasy world full of so many different species of beautiful girls now. If you enjoyed Monster Musume no Iru Nichijou’s growing dynamic between a human and an alien species, you’ll love Kono Subarashii Sekai no Shukufuku wo!
2. Rokujouma no Shinryakusha!? (Invaders of the Rokujyoma!?)
Koutarou, a high school student in Rokujouma no Shinryakusha!?, must find housing on his own after his father is transferred for work. To him, the perfect room and a beautiful landlady are just around the corner, but it turns out to be a scam! Shortly after moving in, a slew of female visitors, including a ghost, an alien princess, and a magical girl, begin to appear unexpected!
All of these enigmatic women want Koutarou’s apartment, but he’s not about to part with it. It’s anyone’s guess at this point. What are the chances it’ll be Koutarou?
Are you sure you want to continue reading this? Both Monster Musume no Iru Nichijou and have a great deal in common. In the first place, the story revolves around a young human boy who is forcibly placed in the company of non-human girls. And to top it all off, the scenarios are strikingly similar! While Kimihito is alone because his parents have relocated for work, Koutarou is separated from his family. When the girls move in, both boys are left alone and vulnerable to the girls’ various manipulations. The reasons for a harem of supernatural “monster girls” moving in with a human boy may differ in the two anime, but the underlying premise is the same in both. For a similar supernatural harem experience, try Rokujouma no Shinryakusha!
3. Shinmai Maou no Testament (The Testament of Sister New Devil)
In Shinmai Maou no Testament, Toujou Basara’s father is a psychotic jerk. In the past, Basara was an only child, and his father was always a lone parent. However, things are about to change for Basara and his father. It’s as if his father suddenly announces his engagement to an overseas woman who already has two daughters. What’s the problem? Basara’s daughters will be moving in soon! And do you want to know the really bad news? We learn that one is a future demon Lord, and the other is a succubus in disguise. Basara may have always wished for a younger sister, but he never expected to get one like this…
Shinmai Maou no Testament’s protagonist, like Monster Musume no Iru Nichijou’s, is abandoned by his parents and must fend for himself. The monster girls are, of course, with him! Even if Kimihito has an entire harem of them living with him, Basara already has his hands full with the two he has to deal with. Shinmai Maou no Testament features two dark supernatural girls, one of whom is a demon Lord and the other a succubus.
Ecchi sequences with supernatural girls and a human boy are featured in both anime. Shinmai Maou no Testament is an excellent follow-up to Monster Musume no Iru Nichijou for fans of the brother/step-sister trope in anime. Even though this is a darker and more intense story, the ecchi harem concept still has a strong resemblance to the original.
4. Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka (Is It Wrong to Try to Pick Up Girls in a Dungeon?)
DANMACHI, also known as “DanMachi,” is a fantasy anime series set in the town of Orario in the fictional world of Dungeon ni Deai. There’s a strange dungeon in the middle of town full of monsters of all levels, as well as tons of loot and experience waiting to be found! It is for this reason that Orario is full of brave souls who are accompanied by a diverse group of friends, including traders, helpers, and the gods and goddesses who help fund and encourage their brave warriors. Unaffiliated with a guild and supported only by the small goddess Hestia, who has no other adventurer but him, Bell Cranel is one such adventurer. A young boy who wants nothing more than to become an honorable warrior and become known for himself.
DanMachi is based on an otome game where the main character can take many different paths, making it the ideal setting for a harem anime. And it makes the most of it. You’ve got DanMachi when you combine it with a fantasy world filled with girls of countless species, from elves to goddesses to girls with fox ears, and everything else in between.
Bell, like Kimihito, is a younger boy who finds himself in a situation where he’s surrounded by women and doesn’t know what to do. Crushes, repulsion, and squabbles with their diverse group of fantasy women are all part of life for them both, and they learn a lot about friendship and other kinds of relationships along the way. But in both anime, where Kimihito lives with a large group of girls and Bell is isolated from the others, the good times and fanservice follow our main characters wherever they go.
As entertaining and light-hearted as they are, DanMachi and Monster Musume no Iru Nichijou are great examples of fantasy harem stories. They work well together without resembling the same anime over and over.
5. Valkyrie Drive: Mermaid
A young woman named Mermaid is taken from her gym class and taken to an exotic and scandalous island called Mermaid. This is how Mamori Tokonome begins Valkyrie Drive: Despite its idyllic setting, Mermaid is anything but idyllic – it’s teeming with danger and predators! But Mirei Shikishima finds Mamori quickly, and she learns from him how to unleash special transformative powers with a passionate kiss to defeat these foes. If they are going to survive their time on Mermaid, they will have to band together and work together as a team.
Mermaid is a shoujo-ai, which means the romance is between two girls rather than a boy and a girl. Because of this, the story’s harem of girls will deal with a heroine rather than a hero in the story. In the end, it’s just another harem of fantasy girls following the lead of a human (mostly normal). Valkyrie Drive: Mermaid’s romance revolves primarily around Mamori and Mirei, but they also meet a slew of other women while exploring Mermaid Island. The romance scenes themselves serve to highlight Mamori’s newly discovered magical abilities throughout the story. Because she can’t activate them unless she feels passionately about something, romance is critical to the plot.
The fantasy element of Monster Musume no Iru Nichijou’s romance stories is always emphasized by all the unique supernatural quirks and features of the different kinds of girls. When it comes to romance, Valkyrie Drive: Mermaid keeps that fantasy and magic element at the forefront of the story.
6. Jitsu wa Watashi wa (Actually, I am)
Asahi Kuromine, the protagonist of Jitsu wa Watashi wa, is a typical high school student with a crush on a female classmate. Except for Youko Shiragami, the girl of his dreams, who is a vampire! When Youko’s father learns of Asahi’s secret, he advises his daughter to drop out of school in order to keep the information about her and her family safe. Asahi, on the other hand, does not want his crush to leave because of him, so he makes a promise to keep quiet. In addition to Youko, Asahi discovers a growing number of otherworldly creatures and must keep them all a secret! Getting him to stop being so easy to read and so bad at lying would be much easier…Will he be able to pull it off?
Only one of the Six Anime like Monster Musume no Iru Nichijou on our updated list is also on our original list: Jitsu wa Watashi wa. Because of the striking resemblances between the two shows and the fact that this one just came out, we decided to keep it! A human boy who finds himself in various romantic situations with one of his harem of supernatural girls is at the center of both anime. For Asahi and Kimihito, it’s Youko, and for Kimihito, it’s Miia. Both have a central character who starts everything off and remains crucial.
Finally, both shows are comedies, so if you liked Monster Musume no Iru Nichijou, you’ll probably enjoy Jitsu wa Watashi wa as well.
