The 14 Worst Anime Sequels of All Time, Ranked

There's nothing like the joy of finding out that your favorite anime is getting a sequel - and there's nothing like the despair of finding out that that sequel was nothing like what you hoped it would be. For this article, we'll be commiserating about some of the worst anime sequels ever created. 

One of the most disappointing examples from 2021 is The Promised Neverland. The first season was stunning, but the second season was so clownish it may as well have slipped on a banana peel and fell face-first into a banana cream pie. But while the lackluster conclusion of Emma's post-escape life is upsetting, it's far from the only example. Remember how absolutely awful The Seven Deadly Sins looked after getting transferred to Studio Deen? 

Vote up the terrible sequels that caused you the most pain. If there are any sequels that you feel are being unfairly maligned, vote those down.

    The Promised Neverland Season 2

    The first season of The Promised Neverland was outrageously popular, and for good reason: it was a tightly paced, mysterious, suspenseful series with great characters and an intriguing premise.

    All of that went right out the window for Season 2. CloverWorks elected to remove multiple arcs, characters, and concepts that appeared in the manga, essentially creating a streamlined version of the story that made little sense to anime-only viewers who were missing a ton of context. 

    The last two episodes were especially egregious. Emma manages to solve basically every problem through random luck or shonen pluckiness, totally casting aside the strategic thinking that defined the previous season. Years of the story are hand waved with a montage - one which made it clear that this was truly the series' finale. No wonder fans of the series are so disappointed!

    The Seven Deadly Sins Season 3

    The first two seasons of The Seven Deadly Sins were produced by A-1 Pictures, an established and well-regarded studio with series like Sword Art Online, Fairy Tail, and Your Lie in April under its belt. A-1 Pictures worked with Aniplex to produce the first two seasons, as well as The Seven Deadly Sins the Movie: Prisoners of the Sky. The movie flopped and Aniplex dropped out. This forced A-1 Pictures to scramble for a new studio to take care of the animation for Season 3. 

    The only studio available to do the job was Studio Deen. While they do have some great titles to their name, Studio Deen doesn't exactly have a stellar track record. And this time around, they were so busy that they had to outsource most of the animation to another studio called March Jack.

    The end results were grim: highly anticipated fights like Meliodas vs Escanor were not only stilted and emotionless, but ugly. Season 3 was a major disappointment.

    Berserk (2016)

    In 2016, Berserk fans got to see the anime continue for the first time since the 90s. But despite being propped up by a solid story, the actual anime was a huge disappointment. CGI animation can be effective when done well, but can look absolutely absurd when done poorly. In Berserk's case, 'done poorly' is too kind of a phrase.

    Some of the more egregious scenes were cleaned up for the Blu-Ray release, but by then it was kind of too late.

    Tokyo Ghoul √A

    Unless there's a truly compelling reason to do so, it's rarely a good idea for anime adaptations to change the plot of the manga.

    That's why so many people found Tokyo Ghoul √A to be so frustrating. While the first season was loyal to the manga, the second season veered in the exact opposite direction by having Ken Kaneki join Aogiri Tree, a terrorist organization that seeks Ghoul Liberation through violent means.

    While this isn't an uninteresting idea, it wasn't anywhere close to a faithful adaptation - and faithful adaptations are what most fans expect and hope for.

     One of the biggest questions on fans' minds, while Black Butler was airing, was whether or not Sebastian was actually going to chow down on Ciel's soul. In Season 2, another demon, Claude, suddenly appears to take Ciel's soul for himself. Whether you wanted to see Ciel escape this grisly fate or wanted Sebastian to do his demon butler thing, this wasn't exactly a satisfying end to a narrative.

    What's more, the other human character, Alois Trancy, is wildly annoying, even once you learn about his tragic backstory. His dynamic with Claude feels like a weird rehash of Ciel's with Sebastian, and the plot doesn't advance at all. Why was it like this? Well, this is yet another case of the anime refusing to follow the manga. At least there are sequel OVAs like Book of Circus that are actually good.

    Kemono Friends II

    Kemono Friends was a smash hit anime that was never really expected to do well in the first place. Most fans attribute its success to the director, Tatsuki. He used a defunct game as a springboard to create a warm and inviting atmosphere and genuine character development.

    But Tatsuki was abruptly fired from Kadokawa, and the second season was spearheaded by Ryuichi Kimura. It's not clear why this happened, but some speculate that Tatsuki was only given creative control because Kadokawa assumed the series would fail - and when it succeeded, they wanted to squeeze as much profit out of the series as possible. 

    This didn't work. Kimura was unable to create the same vibe that so captivated the series' fans. Instead, Season 2 felt like a tired rehash of the same concepts without any of what made the first season special.
