10 Must-Watch Anime That Left Us Wanting More Seasons

Ever finished an incredible anime, only to be left with an ache for more? You’re not alone! Some series capture our hearts, build fascinating worlds, and introduce unforgettable characters, yet conclude far too soon or take an unexpected turn. Get ready to revisit some truly amazing anime that deserve another season to continue their captivating stories. Now, let’s get started!

10. Ranking of Kings: A Beautiful Narrative Begging to Continue

Ranking of Kings stands out as one of the most compelling battle anime in recent memory. Its protagonist, Bojji, is far from typical; despite his small stature, he might be one of anime’s greatest sword-fighters, having learned to exploit the weaknesses of any opponent or object through his training with Despa.

Bojji prefers diplomacy, using his best friend Kage to relay his intentions, but the anime also delivers some of the most inventive duels in the genre. Sadly, the second “season” was an anthology, offering short stories set in the popular universe instead of a direct continuation of its incredible narrative. Fans are eager for the main story to pick back up!

9. Deadman Wonderland: Canceled Too Soon, Deserving a Revival

Upon its initial release, Deadman Wonderland faced poor reviews and ratings, leading the studio to alter its ending and cancel the series. Surprisingly, the anime has since garnered a dedicated modern following, now that it’s being discovered by a broader audience. These new fans are clamoring for an adaptation that truly follows the beloved manga.

Ganta Igarashi’s anime journey lasted less than a year, leaving many interesting and intricate plot lines unexplored. While hope for a rework seemed lost, the recent revival of Blue Exorcist offers a glimmer of possibility. Unfortunately, for now, Ganta’s quest remains with a less-than-satisfying conclusion.

8. Delicious in Dungeon: The Main Quest Remains Unresolved

Delicious in Dungeon elevates the dungeon-crawling genre to new, delightfully quirky heights. While many series feature dungeons, none focus so heavily and beautifully on food. The unorthodox meals look incredibly delicious, making every bite a visual feast.

The anime’s first season wraps up nicely, but the overarching narrative is far from over. The party’s main quest remains unresolved, and there’s plenty more manga content for the showrunners to adapt. A new season is in production, and while the release date isn’t set, fans can likely expect to see Laios, Senshi, and the rest of the gang before the year is out.

7. The Promised Neverland: Season Two Needs a Complete Do-Over

The Promised Neverland Season 1 is hailed as one of the best horror anime of all time. It initially presents a seemingly happy orphanage, but quickly unveils a much darker truth. The anime masterfully builds a sense of unease and tension as the audience realizes the terrifying stakes for the children.

The series excels at portraying the children in constant, imminent danger, with every escape attempt met by an equally effective deterrent. However, the second season completely missed the mark, crafting its own narrative that led to a premature and utterly unsatisfying ending. A potential The Promised Neverland Season 3 could completely retcon the previous season and return to the beloved source material.

6. Claymore: A Dark Fantasy Gem Deserving a Full Reboot

Claymore is one of the most underrated dark fantasy series from the early 2000s. While many modern anime fans might not be familiar with this captivating title, it enthralled audiences during its original run. Unfortunately, the anime quickly caught up to the manga and, instead of going on hiatus, created its own conclusive ending.

While the original ending isn’t objectively bad, it deviates significantly from the source material. A reboot of the series would undoubtedly find massive success today. With similar titles like Clevatess set to be major hits in Summer 2025, there would certainly be a hungry audience for a faithful Claymore continuation.

5. Wistoria: Wand and Sword: A Promised Return That’s Overdue

Wistoria: Wand and Sword explores the intriguing question of how someone without magic would survive in a magic-dominated world. Despite his lack of magical abilities, Will Serfort is one of the strongest fighters at his elite magic school. His dream is to reach the pinnacle of wizardry through sheer physical prowess alone.

The first season of the anime concluded in an interesting and unexpected way. Although a second season was teased, its return date remains unconfirmed. Official word points to a 2026 release, but this is subject to change. Nevertheless, fans are eagerly awaiting their magicless hero to wield his sword once more.

4. Hell’s Paradise Season 2: The Dark Shonen Saga Needs Its Conclusion

Hell’s Paradise (Jigokuraku) features one of the deadliest locations in anime: Kotaku, a place theoretically on par with Hunter x Hunter’s Dark Continent. It’s teeming with dangerous flora and fauna, posing a risk even to Gabimaru the Hollow, the protagonist and most powerful assassin in the series.

Gabimaru might seem heartless, but his reason for fighting is one of the most heartwarming in shonen: if he can return from Kotaku with the Elixir of Immortality, his crimes will be forgiven, allowing him to reunite with his wife. A second season has been announced for January 2026, and it truly can’t come fast enough for eager fans.

3. Mashle: Magic and Muscle: Left Hanging, Despite Its Overpowered Hero

Mash Burnedead from Mashle: Magic and Muscles is arguably one of the strongest characters in anime. Like several other similar characters, he cannot use magic in a world where it’s the social norm. However, in Mash’s case, those without magic are mercilessly slaughtered. While Mash is incredibly strong, even he can’t completely avoid the entire magical government.

To avoid a tragic fate for himself and his adoptive father, Mash uses his comically impressive strength to masquerade as a wizard. At first, no one notices the difference between his “muscle magic” and real wizardry. Yet, cracks begin to form as Mash aims to achieve one of the highest ranks in his school, leaving us wanting to see how his facade continues.

2. Btooom!: Ready to Capitalize on the Death-Game Craze

Btooom! centers around a gamer forced to play a real-life version of his favorite video game. Given the immense popularity of death-game series like Squid Game today, this anime is perfectly poised for a reboot. Although the series did receive a video game tie-in, a second anime season was never announced.

The anime originally ended because it caught up to the manga and didn’t have a large following. However, the modern market is ideal for Btooom!’s huge potential. While similar series have graced the genre, none possess the same untapped potential. The existence of the game, at the very least, proves continued interest in the franchise even after the anime and manga concluded.

1. Soul Eater: A Deserved Reboot to Follow the Manga Faithfully

Soul Eater is undoubtedly one of the most underrated shonen series. While it didn’t initially release in a seasonal format, it is absolutely crying out for a reboot. Such a reboot would likely conform to modern release practices, making it even more accessible. All this is to say, Soul Eater desperately deserves a second season that actually follows the manga.

The original series begins to diverge significantly from the manga around Episode 36. From that point on, the anime follows its own, much less popular narrative. Either a retcon or a complete reboot would do the series a world of good. Soul Eater has countless potential, but ultimately failed to deliver an ending worthy of this popular shonen.
