Some shows, on the other hand, can go on for as long as you want them to. Is there a long-term anime series worth watching?

In the world of anime, at least when it comes to most series, a second season is an elusive beast. Some series only run for a single season of 13 episodes, but others seem to go on for years and years, accumulating thousands of chapters in the process. Others

It’s important to remember that quantity does not equal excellence. It doesn’t necessarily mean that the length of these shows justifies their popularity, even if all of the episodes in the universe have been watched. With that, here are some of the best and worst long-running anime.

1. World Trigger

World Trigger

Toei Animation’s World Trigger anime can finally be watched now that season 2 has been confirmed. World Trigger is based on a manga by Daisuke Ashihara, which depicts an alternate reality in which a gate opens to a world filled with monsters known as “Neighbors.” As the National Defense Agency works to keep humanity safe while also striving to understand more about this odd world, the anime chronicles the story of the characters.

Despite its reputation for a delayed and disappointing start, World Trigger’s characters and setting are well-established by the end of the first episode. After about 20 episodes, things really take off, especially with the start of the Large-Scale Invasion Arc. World Trigger only gets better and better from then on out.

2. Fairy Tail

Fairy Tail is a calorie-laden slurpee. You can enjoy a dinner like that, but there are better options out there. While Fairy Tail is one of the best shounen series out there, it loses a lot of steam as it progresses. Although the animation is constantly present, it soon begins to focus too much on fan service, and the characters’ actions are rarely punished.

After the first hundred episodes, Fairy Tail has a few great points, but it becomes erratic after that.

3. Attack On Titan

Attack On Titan

Attack on Titan appears to be coming to an end with the announcement of a fourth and final season to be released before the end of the year. It’s been a thrilling experience that keeps getting better and better. An action-adventure tale about the struggle of a human named Eren to survive in a planet ruled by monstrous beings known as Titans, Attack On Titan started off as a pretty easy series in which Eren appeared to be the “chosen one.”

It was dissipated in following seasons, although political intrigue was also introduced. While Attack On Titan’s first season may not have lived up to expectations, it’s still worth watching for a while longer.

4.  Detective Conan

Since its 1996 anime debut, Detective Conanis has aired more than a thousand episodes, making it one of the most successful episodic series ever. Detective Conan is a well-written and entertaining show, but its underlying story is largely ignored in favor of the show’s monthly mysteries.

Many of Detective Conan’s plots are enjoyable, although a large portion of the anime’s substance is disposable. As a result, it’s the kind of show that’s perfect for when you just want something quick and to the point. Detective Conani is difficult to suggest as a long-running anime.

5. Reborn!

In spite of a bad start, Reborn! blossoms into a wonderful shonen series that makes the most of its mafia-themed premise.

One day, a baby-faced hitman named Tsuna is dispatched to Japan to train the shy youngster who has been named after the Vongola Family, one of the most powerful organized crime families in the world.

Rebornmomentum !’s lasts for the remaining 180 odd episodes once the Kokuyo Arc begins at episode 20.

6. One Piece

One Piece

There is less and less to praise One Piece’s anime version with each passing year. After Enies Lobby, One Piece advances at such a brisk pace that each new storyline after that feels like a drag. It’s a shame, given the incredible artwork of Eiichiro Oda’s manga, that One Piece’s animation is so inconsistent.

However, One Piece is still a wonderful trip up until the time skip, which occurs in episode 517. After then, it’s best to just stick with the manga or anime.

7. Gintama

A spoof of shonen anime, Gintama is an adaption of Hideaki Sorachi’s manga. When it’s at its best, Gintamahas a cast of characters who are iconic in their own right, focusing on the Odd-Jobs group and their willingness to do everything to make a fast cash.

With almost 350 episodes, Gintamais a big project, especially considering that it began with a moderate pace. It’s worth the effort, however. Even as the anime shifts its emphasis from comedy to action, Gintama manages to remain consistently entertaining.

8. A Certain Magical Index

Almost a recommendation ifA Certain Magical Index terminated after its second season. Unfortunately, the third season’s adaptation of one of the light novel’s most important plots is so bad that it devalues the entire series going forward. To keep up with the action, it’s essential that you’ve read the novels before watching Season 3, which picks up the stakes of the battle between magic and science after two seasons of build-up.

In order to understand A Certain Scientific Railgun, you should watch A Certain Magical Index’s anime.

9. Hajime no Ippo

Hajime No Ippo

In general, sports anime have a better track record when it comes to securing a second season. The best films in this genre not only have a wide audience appeal, but they also feature a compelling blend of action, comedy, and endearing characters. It doesn’t matter if you’re a boxing lover or not; Hajime no Ippore is the greatest in the category.

Because the anime is mostly an advertisement for the manga, the whole plot may not be adapted for some time.

10. Pokémon

Pokémon, which has aired more than a thousand episodes, joins the likes of One Piece and Detective Conana as anime classics. Despite the fact that it will be a strange day whenPokémon stops, this is one long-running anime that is not worth watching in full.

For the sake of your sanity, it’s best to stick with only a few seasons ofPokémon instead of trying to watch the entire series.

11. Natsume’s Book Of Friends

Natsume’s Book of Friends is a quaint slice of life anime that focuses on the titular boy’s efforts to free the spirits who are submissive to The Book of Friends. Each season is around 13 episodes long.

Natsume’s Book of Friends typically sets a calming tone and concentrates on character development rather than action, despite the fact that there are a few explosive passages. Even though the anime has never been bad, each each season becomes better and better.

12.  Bleach


There are some amazing arcs in Bleach, but the anime is plagued by filler arcs that are both excessive and of low quality, causing it to lose steam.

Ichigo is perhaps the greatest offender when it comes to the show’s characters and plot developments, both of which remain rather stagnant throughout the game. In no way am I saying that Ichigo is a weak lead character; on the contrary, Ichigo’s character evolution is mostly focused on new attacks and transformations, rather than on deeper character development.

13.  Monogatari

Those looking for a new style of anime should give theMonogatariseries, which is the definition of an acquired taste, a try. Monogatari, based on Nisio Isin’s light novel series, is a multi-season adaptation that follows high school student Koyomi Araragi as she investigates supernatural incidents affecting other young women.

Monogatari is one of those anime that stays with you long after you finish watching it, thanks to its stunning visuals and thought-provoking content. First season Bakemonogatari serves more as an introduction to the characters rather than a solo season, therefore it’s important to point that out.

14. Dragon Ball Super

Dragon Ball Super Broly (2018)

There is no need to introduce Dragon Ball. They’re widely regarded as classics, although the ensuing series are far more polarizing than the original anime and Zare. Even though the quality ofDragon Ball GT changes so frequently that it is at once fantastic and awful,Dragon Ball Superis an even bigger mixed bag.

Even the strongest arcs of the anime have serious issues, even if the show improves over time. Both the Universal Survival Saga and the “Future” Trunks Saga have a promising start, but neither has enough content to sustain its 54-episode duration. Dragon Ball Super can be laughable when it’s poor.
