10 Anime Series That Desperately Need a Sequel

Updated on February 2, 2020

Ria is an avid anime and sci-fi fan who loves gushing about her latest favorite shows.

Though anime studios are cranking out more sequels than ever, sometimes amazing series are left without a continuation. This can be due to lack of source material to draw from, lack of fan interest, or even conflicts with the original creator.

Fans will often be patient and wait years for continuations to be announced. However, once enough years have passed, fan interest typically wanes and series with high potential are often left with weak endings.

Here are ten TV series that desperately need sequels.

Library Wars


Toshokan Sensou, or Library Wars, received a 12-episode anime adaptation in 2008 and a sequel movie in 2012. The story's premise had great potential, especially since it explored questions of censorship and creative freedom.

However, the anime adaptation was too short to explore any of these issues in depth. It also didn't allow the main characters' romantic relationship to fully develop. While they finally got to go on a date in the movie, even this is cut short by the rest of the movie's plot.

Even a 12-episode sequel series could continue the novels' plot and character development adequately. Unfortunately, fan interest seems to have waned after the 2012 movie.

Fullmetal Alchemist: Brotherhood


Some would argue that Fullmetal Alchemist: Brotherhood wrapped up its plot nicely and doesn't need a continuation. However, let's face it: how likely is it that Ed and Al's world would remain peaceful for long? In a world as complex as theirs, the power of alchemy would surely be abused by new villains soon enough.

It would be amazing to see a new generation of alchemists follow in Ed and Al's footsteps, and see how Roy and the rest of the military members continue to lead and inspire. Since it's been 10 years since the Brotherhood remake, maybe it would be appropriate to make a sequel set 12-14 years after, so that fans could relate to the grown-up versions of their favorite characters and new teen characters could be introduced.



Like Library Wars, Baccano! has a wealth of unexplored plot and worldbuilding in its source novels. The TV series included a total of 16 episodes, but the light novel series spans a whopping 22 volumes! In other words, the TV series barely scratched the surface of what the massive cast of characters has to offer.

Though the TV series wraps up one major plot arc, there are still nefarious forces moving around Manhattan. Luckily, the novels are being translated into English and are available in North America, but that's no substitute for the slickly-animated action and hilarious voice acting of the anime. Hopefully someone will at adapt another arc or two into a TV series or movie.



Blood+ was blessed with a plot line that wrapped up fairly well at the end of its 51-episode run. The romantic relationship between Saya and Haji, however, was seriously underdeveloped. Since the premise revolves around Saya basically being immortal, it's only natural that the series should get a proper sequel, even if it's set far in the future.

While the 2011 series Blood-C is arguably a sequel, it basically only reuses the mythos of the original series. Saya is no longer the same, and Haji doesn't even appear. There are no references to the characters or plot of the original Blood+, which is disappointing. Blood-C also relies far too heavily on shock value and a disturbing plot twist in the last few episodes.



NANA ended somewhat abruptly after just 47 episodes, and the characters' romantic entanglements ended up feeling somewhat rushed. The series was excellent overall, though, and there's massive potential for a sequel to pick up right where the original left off. Main characters Nana Osaki and Nana Komatsu still have years of their lives left ahead of them, and the drama between them and their friends is truly gripping.

The manga has been on indefinite hiatus since 2009, though, and creator Ai Yazawa hasn't produced any manga that entire time! Even if the manga's hiatus ended soon, it would still be a while before an anime continuation based on the manga could be created. There are still many loyal fans of the series around, though, so anything could happen.

The Irregular at Magic High School


Like many great fantasy light novel series, The Irregular at Magic High School has excellent worldbuilding with heavy background politics in play. Unfortunately, the first season of the anime only touches briefly on all of this - which is only natural, considering the writers have to move the plot and character development along as well.

Since the first season was a full 26 episodes, the plot didn't feel horribly rushed, but it's hard to feel satisfied knowing that there's so much else to be explored. Hopefully fan demand causes the series to be brought back soon, before it gets overshadowed by newer light novel adaptation. The remaining scenarios explored in the light novels would be excellent in animated form.

Highschool of the Dead


The smash hit series Highschool of the Dead combines zombies, violence, and fanservice in an apocalyptic fantasy geared at teenage boys. It had a lot of fans outside of that demographic, though, in part because of how well it depicted the drama of a zombie apocalypse. The characters didn't just just have to fight zombies - they had to deal with the darker side of human nature as well! The finale of the anime adaptation was controversial because of how it handled one of the central romances, but it could easily be undone by a sequel.

Highschool of the Dead's manga underwent multiple hiatuses before the writer's death in March 2017. The illustrator is still alive, but a continuation of the manga seems unlikely at this point. At the very least, though, there's enough material for an anime studio to adapt the rest of the manga and then create a better anime-only ending.

Yuri!!! On Ice


Yuri!!! on Ice is getting a movie prequel, but that barely scratches the surface of everything this series has to offer. Friendship, romance, and the thrill of competition can barely be conveyed in a 12-episode series, especially with the number of characters YOI has. At times, fan-favorite supporting characters like Phichit don't get all the screentime they deserve.

A sequel or spinoff would definitely be warranted. It could even focus on Yurio, Phichit and other characters as they continue their journeys, while still giving us glimpses and updates on Yuri and Viktor as their relationship continues. Hopefully, the series' popularity causes anime studios to green-light future installments in the story.



The critically-acclaimed Claymore manga has 17 volumes, but the 2007 anime adaptation only has 26 episodes! Raki and Claire's epic journey doesn't deserve to be cut that short. While the TV series does an excellent job adapting a few key story arcs, it ends up feeling seriously unfinished.

Plus, some of the best battles in the entire series are left out of the adaptation. With all of the advances in animation technology since then, a sequel is definitely justified. Since the manga ended in December 2014, fan interest has likely waned some, but it could probably make a significant comeback. Claymore's particular style of dark fantasy is a rare gem in the anime world, especially in the swamp of cookie-cutter moe and isekai anime that airs every season.

Akatsuki no Yona


Akatsuki no Yona is an epic coming-of-age story set in a fantasy kingdom rife with betrayals and rich worldbuilding. Despite the mature tone, the manga's story struck a chord with a wide range of viewers. Its characters were exceptionally well-rounded, a rarity among shoujo fantasy anime.

Unfortunately, with only 24 episodes, the anime adaptation doesn't even begin to cover the plot. Yona's journey basically gets reduced to a reverse harem fantasy, leaving out some of the best parts of her journey.
