Like any decade, the 2010s saw the world of anime undergo some massive changes. Isekai anime became the dominant genre for the industry. Streaming became a vital part of consuming anime, as fans switched to digital from buying physical copies or watching anime on cable. And a new wave of major juggernaut anime took over throughout the decade, starting with Attack on Titan, then My Hero Academia, and eventually One Punch Man and Demon Slayer. These anime gradually got more seasons to help finish their stories thanks to their massive audiences.

However, there were some 2010s anime that were beloved that weren’t quite so lucky. Many of these series had much more story left to tell, but never went beyond their second, or even first, season. Even now, they could desperately use another season to help finish their stories. Fortunately, in this modern era, anything is possible.

Grimgar: Of Fantasy and Ash Is Unlike Any Other Isekai Anime

At one point, Grimgar of Fantasy and Ash was one of the top anime that isekai anime fans wanted a sequel from. It’s basically for every fan who wanted something different from the usual isekai anime series, as it follows a group of inexperienced warriors as they try to survive in a fantasy environment. Rather than watching them develop incredible powers, they struggle to even take down goblins and slimes to pay for clothing.

Alongside incredible character writing, Grimgar featured some of the best worldbuilding in isekai anime, drawing viewers into its world with its mysteries. By the end of Season 1, though, they’d barely tapped into the source material at all. With almost twenty more light novels to adapt, it’s safe to say Grimgar would still fit into this modern era.

Sekirei: Pure Engagement Was One Of The Best Battle Harem Anime Series

Sekirei is from that brief era of the late 2000s and early 2010s when harem anime caught on, particularly battle harems. The series follows 19-year-old Minato Sahashi after he meets Musubi, a beautiful woman who happens to be a “Sekirei”, unique beings with supernatural powers. In meeting Musubi, Minato gets pulled into the Sekirei Plan, where 108 Sekirei engage in a vast tournament to see who can be the last Sekirei standing.

Sekirei is one of the best harem anime, as it’s one of the few with a plot worth keeping up with. Each season had just as much, if not more, combat and worldbuilding, as it did romcom elements. Yet after two seasons, the series stopped and never really made a comeback, leaving viewers without a real finale. With the manga wrapped up back in 2018, it’d be easy enough to finish adapting this storyline.

Hunter x Hunter (2011) Should Be Continued Through OVA Series

Hunter x Hunter is one of the most popular anime of its era, and one of the best shonen anime series of all time. There’s nothing quite like the series, as it isn’t afraid to build a world that doesn’t totally center around its protagonist. While Gon is an important part of the series, Hunter x Hunter was never afraid to go long stretches developing other characters and factions, often showing opponents Gon wasn’t nearly strong enough to fight.

The series ended with Gon finally talking with his father, Ging, making it the perfect place to stop if it’s never going to continue again. However, the manga has been going on sporadically in the decade since it ended. Perhaps the series could get a series of OVAs like the ’99 Hunter x Hunter did to continue the story.

Tiger Mask W Can Take Advantage Of Wrestling’s Current Popularity

Tiger Mask W was a sequel series to a classic wrestling anime from the late ’60s. The series focused on two fledgling pro wrestlers aiming to get revenge on the powerful Global Wrestling Monopoly organization that destroyed their pro-wrestling team. Years later, the two emerge as masked wrestlers Tiger Mask and Tiger the Dark, battling against GWM and other opponents in their goal to get revenge.

Tiger Mask W was an awesome anime for pro wrestling fans, but while it had a solid ending, there’s still plenty they could follow up on. Wrestling is more popular than ever now, meaning there’s a greater chance it could reach even more fans. With the real-life company New Japan Pro Wrestling sponsoring the original, it’s possible they could feature even more of their wrestlers to make it a bigger showcase.

Sword Oratoria Develops One Of The Most Powerful Side Characters In Its Universe

Sword Oratoria takes place in the same universe as DanMachi, or Is It Wrong To Try To Pick Up Girls In A Dungeon?, but contains a twist. Rather than centering around Bell Cranel and the Hestia Familia, the main character is Ais Wallenstein and her Loki Familia. While the series has some overlap with the main story, it mostly develops these characters on their own, making them more fully formed.

Sword Oratoria will seem pointless to some, but it does great work in further developing Bell’s role model, Ais Wallenstein. Given much of the reason people love DanMachi is its worldbuilding, a side story that further develops its universe is a great idea. More than that, though, the main DanMachi anime is close to catching up with the light novel, so releasing more of this series still gives DanMachi fans something to enjoy.

Nanoha ViVid Needed To Finish Fleshing Out The Nanoha Universe

Nanoha ViVid follows Nanoha and Fate’s adopted daughter, Vivio, who’s a reincarnation of the mighty Sankt Kaiser. While still in elementary school, Vivio’s magic has grown enough to be granted an intelligent device that lets her tap into her magic powers. With those powers, Vivio decides to enter a martial arts tournament for magicians that leads her to make new friends and learn more about her past.

Nanoha ViVid was a fun magical girl anime series that changed things from the norm. Rather than being focused on monsters of the week, Vivio and her friends engaged in a traditional battle tournament. However, the series barely tapped into the surface of the full manga in its single season. While a second season was promised at some point, it never materialized.

Magi: The Kingdom of Magic Stopped Just Before Entering The Best Arcs

Magi: The Labyrinth of Magic was an underrated battle shonen anime that achieved decent popularity in the 2010s. The series focused on two young men, Aladdin and Alibaba, as they explored the world solving dungeons that grant incredible riches and power. While Alibaba aims to create his own country, Aladdin learns that he is one of the Magi, a magician wielding the power necessary to shape the world.

Though fans had issues with the first season of Magi, the second season was a significantly more accurate adaptation. By the time it ended, though, there wasn’t quite enough material for a third season. For a time, it felt like the anime might make a comeback, potentially after the manga ended. However, the manga ended in 2017 and there’s been no sign of a third season. Given the story truly heats up with the later arcs, it feels like fans were robbed of a potential classic.

Magic Kaito 1412 Should Allow Kaito To Finally Get Vengeance For His Dad

Magic Kaito 1412 follows Kaito Kuroba, a high school student who spends his spare time as the phantom thief, the Kaito Kid. Kaito follows in the footsteps of his father, who was murdered by a criminal organization while on a caper. Learning the organization is after a special jewel known as Pandora, Kaito commits jewel theft around the world to find the Pandora before they can.

While it may not seem like it, Magic Kaito 1412 actually predates Gosho Aoyama’s other, more popular manga in Yaiba and Case Closed. Still, unlike Case Closed, Magic Kaito actually feels like it could reach a finale one day. With recent Case Closed movies have been pushing forward Kaito’s own storyline a bit more, it might not be a bad idea to bring this series back for a sequel. More than that, Kaito is just such a charismatic protagonist that he deserves his own series again.

Noragami Could Actually Finish Now That Its Source Material Is Over

It’s safe to say at this point that Noragami has attained cult classic status for longtime anime fans. The series was beloved when it aired, but never quite achieved the superstar level of contemporary series from the 2010s, like My Hero Academia or One Punch Man. It did still manage to get two seasons, though, with the second season having one of the greatest anime OPs of all time.

Still, anyone could see the anime was just getting started when Noragami‘s second season ended. Though it’s been a decade since then, there’s oddly no better time to give this series another season than now. The series’ long-running manga only ended in 2024, so a potential third season could actually offer a chance at actually finishing the series.

Heroic Legend of Arslan’s Anime Stopped After Catching Up To The Manga

The story of the Heroic Legend of Arslan is an anime classic, dating back to the original OVA series. In the 2010s, though, the series got a manga courtesy of Hiromu Arakawa, which became popular enough to get an anime adaptation. Fans once again got to see Arslan sent on a journey to gather allies after losing his kingdom, though this time as a full television series.

Heroic Legend of Arslan was an awesome fantasy series for the modern era, but lasted only two seasons before vanishing from the airwaves. Presumably, they didn’t want to keep going after catching up with Arakawa’s manga adaptation. However, it’s been years since the last season, so there’s more available to adapt now. Plus, the novels wrapped up so, in theory, they could just finish the series based off the original novel adaptation.
