Unfortunately, we probably won’t see any of these getting more anime.
Weekly Shounen Jump is the magazine that published most of the manga from which famous battle shounen series were adapted. Not all the adaptations were great, though: some were just not that well-made, and some were left unfinished.
During the 00s and the 10s, Katekyou Hitman Reborn! was one of the biggest shounen series out there — arguably as big as One Piece, Naruto and Bleach. Later, however, its popularity started to wane as it ended in 2010 without adapting the entirety of the manga.
While fans definitely have issues with the adaptation — slice-of-life moments are shuffled around, and fillers ruin the pacing — the anime isn’t bad. It is unfinished, however: roughly a third of the manga still needs to be adapted.
Nisekoi
MyAnimeList score: 7.72 for manga, 7.56 for anime
Nisekoi is often seen as a predecessor for harem romcoms like The Quintessential Quintuplets (5-toubun no Hanayome). Essentially, the entire point of the manga is “which girl would win?”. However, while the formula can be tiring now, it was fresh back in the early 2010s, and the visuals by studio Shaft certainly helped the adaptation.
Unfortunately, the same studio released a very poor second season. It skipped a lot of content and made many manga fans disappointed. As such, the anime needs a full remake — or at least a continuation from where S1 left off.
MyAnimeList score: 8.16 for manga, 8.50 for anime, 5.28 for S2
This topic is akin to beating a dead horse, but yes, the second season of The Promised Neverland (Yakusoku no Neverland) is actually just that bad. The production values went down significantly, the pacing was way too fast, and too many events were cut out to cram the remainder of the manga in one cour.
While apparently, these changes were approved by the mangaka, fans were still disappointed with S2. It’s considered one of the worst sequels in all of anime, and a remake of what S2 covered is very much needed.
Sumo isn’t a sport that attracts many otaku outside Japan, but the anime adaptation of Hinomaru Sumo (Hinomaruzumou) made some waves in the English-speaking circles when it aired back in 2018–2019.
It makes the sport actually interesting without making it confusing for the viewers, and attracts many with its amazing opening songs. The story itself is good, too, but the series still didn’t sell well. As such, it is remaining unfinished in the anime form.
Naruto
MyAnimeList score: 8.08 for manga, 8.00 for anime
Does Naruto need a remake? Fans never agree about that, and there are many arguments over the question. On one hand, it never needed a sequel, yet Boruto still exists. The anime is finished, and, if you skip fillers, is a perfectly serviceable series.
Others, however, want it to be remade with better animation and without fillers. One Piece is getting a remake, so why can’t Naruto get one, too?
Hunter x Hunter was first adapted in 1999 and then got a remake in 2011. Now, some fans believe a sequel for that remake is needed.
While the anime ended at a decent stopping point, there’s quite a few unadapted chapters in the manga — enough for at least two more cours. Togashi can’t draw very often due to his health issues, but Hunter x Hunter fans crave for more content of their favorite.
Medaka Box
MyAnimeList score: 7.79 for manga, 7.02 for anime
Nisio Isin is known for anime like Bakemonogatari and Katanagatari, but he also was the writer of the story for Medaka Box — one of the weirdest shounen manga ever created. Simultaneously a parody and a tribute to Weekly Shounen Jump, it has some dedicated fans.
And they tend to agree on one thing: the anime isn’t bad as an adaptation, but the first two arcs of the manga are the worst ones, and the anime only adapts them. The third arc is the best one, and the anime ended on a cliffhanger just before it, too. Because of that, they are begging for a sequel.
Eyeshield 21
MyAnimeList score: 8.48 for manga, 7.92 for anime
Eyeshield 21 was very popular with sports fans in the 00s. The anime is one of the few series out there about football (not soccer), and it’s just an entertaining story altogether.
While it was decently received, sometimes, the animation wasn’t the best. It also stopped halfway through, and fans would be content with both a remake and a sequel.
Undead Unluck just finished recently, but fans are already asking for a sequel. It’s understandable, why: the anime seems to be generic at first, but that impression is deceiving.
The worldbuilding and the abilities in the series are incredibly complex, and are impossible to explain without any context. As such, fans want it to be continued.
Houshin Engi
MyAnimeList score: 7.47 for manga, 7.07 and 5.39 for anime
Never heard of Houshin Engi? We can’t blame you. The manga is fairly old — it ran from 1996 to 2000 — and has a lot of content. It had quite a huge fandom in the 00s, too, and fans desperately wanted to see a proper adaptation.
The first adaptation of Houshin Engi, Soul Hunter (Senkaiden Houshin Engi) was poorly received. Fans didn’t like that it was essentially just a teaser for the manga, which failed to adapt all the content.
The existing remake, Hakyuu Houshin Engi, which aired in 2018, was worse. It cut the content down so much that it adapted 200+ chapters in just two cours. Perhaps another remake is needed.
