Isekai manga are loaded with all sorts of action, adventure, and drama, yet these narratives also happen to span several long chapters and volumes. While traditional, long-hauled manga present a fleshed-out narrative, they can also be rather tedious to finish. This is where one-shot isekai manga come in, offering the same adventure-laden experience, but in one concise and continuous chapter.

18 Best Isekai Manga That Do Not Have An Anime

Though there are tons of isekai anime, fans feel the genre could still use more variety. Here are some great isekai manga that deserve adaptation.

Since most isekai narratives tend to revolve around long fantasy-like adventures, one-shot manga are usually overlooked for this specific genre. However, several mangaka have come up with enticing one-shot manga that present an equally exciting isekai experience, without compromising on the storyline or characters. While one-shots are usually created for manga serialization contests or promotions, they still serve as perfect standalone stories for a quick read.

6 Isekai de Yuusha Tuber Yattemita

AniList Rating: 5/10

Staying true to the standard isekai antics, Isekai de Yuusha Tuber Yattemita presents a novel yet absurd narrative. Eisuke Watari finds himself reincarnated in an RPG-like world, expecting to be granted some sort of overpowered cheat ability. To his dismay, the only skill he gains is being a “MeTuber,” an ability that is entirely useless for defeating the end-game Demon Lord.

Stuck with an unorthodox ability, Eisuke is forced to make do with this power, resulting in an odd isekai journey filled with streaming, garnering subscribers, and fishing for views. Isekai de Yuusha Tuber Yattemita presents a truly whacky premise, though it fits in with the usual isekai thematics, making it an intriguing one-shot isekai manga.

Fans of isekai manga with slice-of-life elements may want to give the following examples a shot if they haven't already.

Despite bearing tendencies towards arson, Homura only burns those who are evil, making this new world the perfect setting for her fiery antics. Waga Homura ni Hirefuse Sekai is a one-shot isekai manga created solely as a promotional feature for the light novel of the same title. Since the one-shot manga only serves as promotional content, readers will eventually have to switch to the original light novel for the complete story.

4 Deadline Summoner

MyAnimeList Rating: 6.76/10

Deadline Summoner follows the standard isekai premise of being reincarnated in a fantasy-like RPG world. However, unlike other isekai manga, the protagonist has no interest in going on dangerous adventures. Instead, Onodera Mamoru wishes to find a safe, well-paying job in this mystical world, which is scarce and impossible to find.

To make matters even more amusing, Onodera finds a few monster girl companions along the way, though every single one of them wants to be more than just companions. Deadline Summoner served as a one-shot pilot for 12 Beast, a manga based on the very same premise. The plot and characters of this one-shot might also feel similar to the hit manga and anime Monster Musume, though this is largely due to both works belonging to the same author, Okayado.

3 Amefuru Aruhi no Isekai de

AniList Rating: 6.9/10

Amefuru Aruhi no Isekai de is a short yet wholesome story about a high school girl being teleported to a parallel world through a rain puddle. The puddle leads to a world similar to Feudal Japan, albeit with the slight alteration of the world’s inhabitants being fox-humans. Izumi becomes embroiled in the conflicts of this world, later becoming key to quelling the discord in this parallel universe.

Being a one-shot isekai manga, Amefuru Aruhi no Isekai de’s narrative feels a bit rushed, though this fact certainly doesn’t take away from the well-written story. Instead, the adorable characters and intriguing storyline leave readers wanting a sequel to the one-shot.

The ending of the game is rather simple, though it relies entirely on completing one of the love interest routes. Being a guy, the protagonist is forced to find a way other than ending up with one of the male love interests, turning this otome narrative into a novel and amusing read. The one-shot was eventually serialized as an entire manga with the same title, though readers can still indulge in this one-shot isekai manga for a quick read.

1 Tensei Oji-san, Heroine ni Naru

Anime-Planet Rating: 3.78/5

Tensei Oji-san, Heroine ni Naru presents an amusing narrative where a 37-year-old salaryman finds himself transmigrated into the body of a high school girl in a shoujo manga. Unlike other isekai protagonists, Wakigata Ittetsu wants nothing to do with this new world, leading to attempts to find a way back.

Tensei Oji-san, Heroine ni Naru’s narrative is quite novel and amusing, though some might have a few reservations about the age difference between the characters and the protagonist. However, the manga keeps the storyline rather wholesome and comedic, without trudging into any of the controversial tropes often found in such a premise.
