When mythical creatures are found to be real, the “Cultural Exchange Between Species” act is put into place to assimilate them into society. Kurusu Kimihito is “volunteered” into the exchange program and must take care of Miia a sexy, snake-bodied lamia who is really into him. Oh, and then a centaur girl, and a harpy, and a slime girl…. The catch is, there is a law against interspecies breeding, so even though Kimihito lives with these gorgeous monsters and they all want him, he can’t touch them! Now what…?

MonMusu is definitely not an Adventure anime, but it most certainly has the Fantasy element since there are mythical creatures all over the place. It also matches KonoSuba in regards to ridiculous situations, clumsy girls, and of course, Harem.

MonMusu is a silly Comedy show, with the typical awkward situations of a slightly Ecchi anime filled with fantasy-world girls with good intentions that can’t seem to get anything right, kind of like our girls in KonoSuba. While it’s not set in an RPG world, it definitely gives you a similar feel.

Louise is a magician who isn’t very good at using magic, which has earned her the nickname of “Zero Louise”. She attends Tristen Academy and in her next test she must summon a familiar. Not surprisingly, she is unable to summon anything powerful and instead summons Saito Hiraga, an average Japanese boy. Unable to break that link, they reluctantly set off on an adventure together as master and familiar.

Though not in an RPG world necessarily, Zero no Tsukaima is set in a world of Fantasy and magic. Louise’s inability to do anything right is very much like our main girls in KonoSuba. And we have a regular Japanese boy being pulled into this crazy situation by a less-than-capable girl who is supposed to be his superior. Saito is also able to manipulate Louise by using her weaknesses against her much like Kazuma does with Aqua.

In Zero no Tsukaima we also have a Harem situation though Saito enjoys it much more than Kazuma does as he is naturally a bit on the horny side. The Familiar of Zero is a fun, Adventure Comedy anime with some Ecchi and Romance mixed in.

A mysterious gate opened in the middle of Ginza in Tokyo and from it came all sorts of fantasy creatures and began to wreak havoc in the city. Luckily, Youji Itami, an otaku and officer of the Japanese Ground Self-Defense Force was there on his day off and was able to take action and get things under control.

After that, Japan sent the Third Reconnaissance Team with Itami as their lead to investigate the “Special Region” on the other side of the gate. There, they face all manner of fantastic characters and difficult situations. They also recruit an elf, a sorceress and a demigoddess who aid them through their adventures.

Fantasy, Comedy, Harem, Gate has everything that KonoSuba has, except Itami and company are completely serious about their tasks and the main characters are all badasses. While they do take their roles more seriously, Itami’s otakuness and some of the running gags in the show are pretty funny. So if you’re looking for something that isn’t a parody, is bloodier and with less painful failures to watch, Gate is where you should look.

After sorceress Lina Inverse joins forces with adventurer swordsman Gourry Gabriev in what is supposed to be a one-time thing, she accidentally liberates an artifact which is the key to resurrecting the demon lord Shabranigdo. Now together, the two must face the dark lord’s servants while gathering fantastic creatures as part of their party.

Ok, so Slayers is a bit… old. BUT, it is also set in an RPG-like world and is full of Adventure, Fantasy and Comedy and it’s set up as a light-hearted parody of the genre, much like KonoSuba.

Lina isn’t a goddess and she’s not a failure either, she’s actually very strong for a 15 year-old. Amelia, who later joins the team, can be a bit naïve and clumsy but believes in justice, which is a bit reminiscent of Raratine in KonoSuba, albeit minus the masochism. If you want to see what Comedy Fantasy Adventure anime was like in the 90s, Slayers is a good one to watch.

A group of strangers awakens in the middle of a dark medieval landscape with no memories of their past. Sometimes they catch themselves saying words they don’t even know the meaning of, though they just roll off their tongues. They are told to join the Reserve Army forces to keep the town safe from monsters and in order to make a living. Manato, Haruhiro, Ranta, Yume, Shihoru and Mogzo team up without any idea of what to do or expect and try, unsuccessfully, to defeat the monsters they come across. What will they do? Why are they there?

While Hai to Gensou no Grimgar is most definitely set in an RPG world where they must join guilds, level up, earn coins and defeat monsters like in KonoSuba, it is far from being a comedy. Based on a novel, this anime is serious and more of an Adventure Drama.

There’s Fantasy, Action and Adventure, and the group of adventurers we follow is not very successful, much like in KonoSuba, but it is also bloody and full of emotion. I’d recommend Hai to Gensou no Grimgar if you want a break from the silliness but don’t want to give up on the struggles of novice adventurers or the RPG Fantasy feel.

In the underground labyrinths of the city of Orario, also known as the “Dungeon”, many adventurers seek challenges, glory and riches along with the help of their goddesses. Bell Cranel is one such adventurer, though he is goddess-less. One day, while in the dungeon, he is attacked and nearly killed by a Minotaur, until a beautiful blonde adventurer saves his life.

Humiliated and now infatuated by the mysterious beauty, Bell continues his search for a goddess and comes across Hestia. She takes him on, and he becomes her first follower. From there on Hestia and Bell continue on adventures and searching for more followers.

DanMachi is set in a real-life RPG world like KonoSuba so it doesn’t lack in the adventure department. It also involves a boy and his less-than-helpful goddess as our main guy’s only support. Hestia is looked down upon by other gods and goddesses because she doesn’t have a big enough group of followers. The two start off living in a run-down building, kind of like Aqua and Kazuma live in the horse shed. And DanMachi most certainly delivers in the Comedy and silliness department. DanMachi isn’t a parody but it doesn’t take itself too seriously, it’s definitely a fun ride with a good balance of laughs and adventure in a game-like world. Also, boobs!
