10 Worst Anime Endings That Left Fans Furious

Anime endings can make or break a series, wrapping up epic stories with emotional payoffs or leaving fans feeling cheated. When a finale fumbles, it can spark outrage, especially after seasons of investment in characters and plots.

These anime, despite strong starts or loyal followings, ended in ways that left viewers frustrated, confused, or betrayed. Here’s my list of the 10 worst anime endings that infuriated fans, counting down from the least upsetting to the absolute most rage-inducing.

10. Kubo Won’t Let Me Be Invisible (2023)

This rom-com follows a shy boy whose invisibility quirks spark cute moments with his crush, Kubo. The anime cuts off abruptly mid-story, with no resolution or confession, due to production issues.

Fans were annoyed by the non-ending, as the manga offers closure. It’s a light letdown but a waste of a charming setup.

9. Soul Eater (2008-2009)

Maka and her weapon partner battle evil in a quirky, gothic world. The anime diverges from the manga, ending with a rushed, nonsensical fight where courage magically saves the day.

The abrupt resolution and loose threads frustrated fans, especially since the manga continued. It’s a fun show with a finale that feels like a cop-out.

8. Gantz (2004)

This gritty sci-fi follows Kei Kurono’s brutal survival in a deadly game. The anime ends mid-arc, with no resolution for the cast or explanation of the game’s purpose.

Fans were left hanging, as the manga goes much further. The open-ended finish feels like a slap after such intense buildup.

7. Bleach (2004-2012)

Ichigo Kurosaki’s Soul Reaper journey captivated fans, but the anime’s original run ends during the Fullbring arc, with a rushed, unsatisfying wrap-up before cancellation.

The lack of closure for major plots, like Aizen’s schemes, enraged viewers, though later seasons adapted more. It’s a sour note for a beloved series.

6. Deadman Wonderland (2011)

Shiro and Ganta fight to survive in a twisted prison with deadly powers. The anime stops after one season, leaving huge mysteries—like the Red Man’s identity—unanswered.

Fans were livid at the cliffhanger, as the manga dives deeper. It’s a gripping show abandoned with no payoff.

5. Berserk (1997-1998)

Guts’ dark fantasy saga ends with the gut-punching Eclipse, where Griffith betrays the Band of the Hawk. The anime cuts off right after, leaving fans with no resolution or hope.

The manga’s continuation made the abrupt stop worse, as viewers craved answers. It’s a masterpiece with a cruelly unfinished ending.

4. The Promised Neverland (2019-2021)

Emma and her orphan friends uncover dark secrets in their idyllic home. Season two crams the manga’s complex arcs into a rushed mess, with a slideshow epilogue skipping key battles.

Fans hated the butchered story and flat character arcs. It’s a stellar first season ruined by a catastrophic finale.

3. Tokyo Ghoul: re (2018)

Kaneki’s ghoul saga wraps up in a chaotic rush, cramming major manga arcs into a single season. The ending feels hollow, with rushed fights and unresolved character fates.

Fans of the manga were outraged by the skipped depth and weak animation. It’s a beloved series with a finale that feels like a betrayal.

2. Erased (2016)

Satoru rewinds time to save a murdered classmate in this gripping thriller. The finale reveals the killer too abruptly, and the rushed resolution skips emotional weight from the manga.

Fans felt cheated by the flat climax and sidelined characters. It’s a near-perfect series let down by a sloppy end.

1. Attack on Titan (2013-2023)

Eren Yeager’s battle against Titans evolves into a complex moral tale. The final season’s ending, while faithful to the manga, splits fans with Eren’s controversial choices and a rushed epilogue that muddies the themes.

The divisive conclusion, with some calling it a character assassination, sparked heated debates. It’s a titan of anime with an ending that left many furious.
