Anime That Promised A Sequel But Never Came Back

Avid members of an anime commentary forum have gathered in a heated discussion about those anime that, at the end of their latest episode, promise a sequel with the dreaded "To be continued" closing screen, but sadly no such continuation ever materializes.

The debate has gained momentum among fans, who express frustration and disappointment over these broken promises. Some argue that these series left plots unresolved and characters in uncertain situations, leading to a sense of dissatisfaction among the audience. Others point out that these strategies could have simply been marketing tactics to increase anticipation and sales for the series.

Amid the controversy, various opinions emerged about possible reasons behind these sequel cancellations. Some speculate that financial problems or internal disputes at animation studios could have hindered the production of new seasons. Others suggest that the show's lack of interest or poor performance in terms of viewership and critics may have led to the decision not to continue the story.

However, despite speculations and theories, uncertainty persists about the fate of these promised series. While some fans remain hopeful that a sequel will one day come to fruition, others resign their expectations and simply lament the fate of these unfinished stories.

"A very good example I can think of is Aku no Hana, the last episode of which spent a considerable amount of time showing a bunch of small clips of scenes that would have been in a hypothetical season 2, however, the series ended up getting very mixed reviews and bombarded in terms of Blu-Ray sales, so it never got a second season."
"Rokka no Yuusha, although I'm aware of the situation of the light novel."
"Obviously I have to mention Noragami, that open ending was to do a third season."
"Hoshiai no Sora, heavens, not having a continuation really continues to hurt to this day."
"The fact that Hoshiai no Sora was going to be a two-part anime that was reduced to one at the last second, with most of the first chapter already released, and that they told the studio to finish it where it was out of time to try and give it a new ending is insane. The director said he'd make sure it had its ending and it never did, which I can't blame them for."
"Deadman Wonderland, what the fuck happened to the rest of the story?"
"Wonder Egg Priority tried to promise a second season, but anyone who has paid attention to the story knows that will never be possible."
"Maybe Drifters?"
"Land of the Lustrous pretty much ended with a cliffhanger, and knowing what happens after you've gone to read a manga, I really need that second season."
"I don't know if this counts, but the second season of Youjo Senki was confirmed years ago, after the film was released. Since then it has disappeared without any new information being given about its cancellation or not."
"Tonari no Kaibutsu-kun really promised a sequel. A shame that will never come given that a second season would actually cover the rest of the manga."
"Btooom! It's a great example of that. Not only did they end the series with a sequel finale and bombardment in the home market, but the mangaka attempted to use milestones for a mobile game in order to entice fans to participate. The game never reached its lofty goals, forcing the servers to shut down within months of the big reveal."
"Chivalry of a Failed Knight".
"Akatsuki no Yona".
"Gekkan Shoujo Nozaki-kun, I miss this series every day."
"No Game No Life is probably the perfect example that the promised sequel isn't there."
"The Zombieland Saga movie, there hasn't been any news in years."
"Gangsta, that anime was too good."
"Watamote. Even in the OVA there are things mentioned about a second season that never came."
"Cautious Hero, you could see the promise of a second season in the final episode, but it never came."
"Sankarea, I think."
"Yuri!! ICE is the perfect example."
"Sewayaki Kitsune no Senko-san. If I remember correctly, they showed stuff from a second season in the final episode, but it was never really done."
"Medaka Box introduced a new villa in the final episode, but a third season never arrived."
"The Legend of the Legendary Heroes, it literally ended with a cliffhanger and a sequel never came about."
"Ouran Highschool Host Club".
"I'm absolutely sure to mention Tomodachi Game. After the first season ended, it started getting good reviews and people really enjoyed it. But I don't know why there was no continuation."
"Aesthetica of a Rogue Hero. That ending promised a sequel, but it never came."
"Kaze no Stigma, unfortunately the author died, so the project will never be continued."
"I weep at the promise of Hai to Gensou no Grimgar."
