Summary

Most anime adaptations of a manga attempt to be as faithful as possible, but in the past and even now, producers would catch up to an ongoing series too quickly and run out of source material to adapt. The production of apopular manga’s anime adaptationoften starts well before the story even reaches its midway point, so producers have to compensate by adding filler, padding, ending the series at an awkward spot, or diverging from the original storyline entirely.

This is becoming less of a problem with newer anime since they’ve adopted the Western ‘seasons’ model, but it persists. This is just a sample of the shows that bypassed their ongoing source material and dealt with the issue in different ways with mixed audience reactions.

Lucy sad and hurt

Studio

ARMS

The anime for Lynn Okamoto’s incredibly edgy manga series ended before the manga finished its serialization. Due to a lack of funds, studio ARMS was forced to condense the 113-chapter series into just 13 episodes. Predictably,the anime ends very differentlythan the manga, leaving things on an ambiguous note, especially regarding the fates of Lucy and the Research Institute’s General Director Kurama.

An official English translation of the manga was released by Dark Horse in 2019, a full fifteen years after the anime, meaning international fans had to wait quite a long time to get the full story about Lucy and the Diclonii.

Ciel and Sebastian from Black Butler

A1 Pictures

The first nine episodes of the originalBlack Butleranime were directly adapted from the manga but the rest of the first season and the entirety of the second is completely original. The first season of the anime covered only the first two arcs, namely the Red Butler arc and the Indian Butler arc.

Despite some changes from the source material, namely the personalities of Elizabeth Midford, Undertaker, and Grelle Sutcliffe, season 1 was well-received and gained a dedicated fanbase.Season 2, on the other hand,had a less-than-positive reception. Luckily for the fans,Black Butler: Book of Circus,Black Butler: Book of Murder, andBlack Butler: Book of Atlanticwere a lot truer to the text.

Vash The Stampede Trigun 1998 Red Coat

Madhouse

TheTrigunanime does closely follow the manga for the most part, except the original series was canceled unexpectedly because the magazine that had been publishing it shut down. Creator Yasuhiro Nightow had to continue the series in another magazine under a different name,Trigun Maximum.

Madhouse had begun production on the anime by the time the third volume of the original manga came out, so needless to say, it quickly caught up with the source material and had a different ending.Trigun Maximumwould continue running for 9 years after the anime ended, so fans of the show may want to pick the manga up if they wantmore in-depth lore and character development.

Chrono Crusade

Gonzo

The anime and manga for Daisuke Moriyama’sChrono Crusadeended around the same time, but as Moriyama wasn’t really involved with the anime’s production, it went in avery different direction during the final arc, particularly regarding some characters' personalities, the religious symbolism, and the climax, as expected.

As a result, the anime and manga are viewed as two separate entities, approaching the same themes from two completely different perspectives. Opinions on which one is better are split, to say the least, among the fanbase.

The Cast of Tsubasa Reservoir Chronicle

Bee Train

Creators CLAMP and many fans were very disappointed with how Bee Train handled the anime adaptation ofTsubasa: Reservoir Chronicle,so much so that CLAMP ended up severing ties with the studio and handing over the rights to Production I.G to make a more faithful adaptation in OVA form.

Not only did Bee Train’s adaptation add a ton of filler arcs, but those arcs ended up breaking many rulesof the CLAMP-verse, like never bringing the dead back to life, and the final arc was all original. In addition to toning down some of the darker themes and failing to adapt a couple of important arcs, many fans agree that it’s best to skip the anime adaptation entirely and just read the manga.

Yuki and Tohru in Fruits Basket

DEEN

While the firstFruits Basketanime by Studio DEEN was undoubtedly popular and had a lot of fans, mangaka Natsuki Takaya was less than pleased with how it turned out. DEEN just barely avoided overtaking the manga, with the anime stopping neatly at around volume 6 (the manga would go on for 23 volumes total).

As the anime’s production started when the series was still ongoing, it had a different take on some characters, particularly the main villain Akito. Fortunately for fans of thebeloved shojo series, they were blessed with a truer-to-the-text remake in 2019 by TMS Entertainment that covers the entire plot of the source material.

Bones

Fans of this classic shonen anime may be surprised to know the series actuallydeviated from the source materialduring its conclusion. The final battle against the ‘Kishin Asura’ was not present in the manga, which continued serialization until 2013.

People who are curious about theSoul Eateruniverse may want to check out the anime first, as it’s a mostly faithful adaptation with next to no filler arcs. If they enjoyed the anime and want more lore, new characters, arcs, and a more satisfactory ending, the manga is worth reading too.

Fullmetal Alchemist 2003 Anime promo art

The originalFullmetal Alchemistanime, which aired in 2003, caught up to the manga’s ongoing serialization fairly early, and thus,deviated from the storyline around halfway throughand presented its own conclusion to the plot. This resulted in an adaptation that only has superficial similarities to its source material.

Several characters were also altered for the anime, for example, villains like Lust were a lot more sympathetic in the 2003 anime compared to the manga or the more faithfulBrotherhoodadaptation.

Pierrot

Long-running shonen anime are infamous for their endless filler arcs, andNarutois no exception. These filler episodes were made to allow a consistent schedule for the anime while producers waited for more material from the manga.Opinions on these breaks from canon vary- some fans liked that their favorite background characters got more screen time, while others preferred to skip the filler arcs entirely.

Unfortunately, the series soon ended up with almost 79 straight episodes worth of filler at one point, frustrating many fans. The post-time skip anime,Naruto Shippuden, has tried to avoid this for the most part, but it was definitely still there.

Dragon Ball - Buu Saga Gohan

Toei Animation

The filler arcs and ‘10-episode power-ups’ of theDragon Ballfranchise have been memed to oblivion, but it’s hardly anything anyone can blame creator Akira Toriyama for. LikeNaruto,the fillers were created to allow the production team to air the anime without interruptions.

Thefight scene pacingin theDragon BallandDragon Ball Zanime was also slowed down for the same reason, leading the anime to feel unnecessarily lengthy in comparison to the manga. This is why new fans are advised to just go straight for the manga, as it is better-paced with no filler arcs.
