Many popular manga are adapted into anime while chapters are being published. Demon Slayer famously additional manga sales right as the shonen title reached its final stretch. Some manga border so close to their anime's release schedule window that the anime needs to produce filler arcs to permit the manga time to run alee. For many anime fans, finishing an anime flavour leaves the door open to catch up with the manga.

However, some anime adaptations come up years -- even decades -- following the completion of their manga. Parasyte, Banana Fish, Vinland Saga, JoJo's Bizarre Chance, and many others were adapted into anime long later their initial runs. I of Netflix'south virtually pop anime, Devilman Crybaby, is an adaptation of a title from the 70s. Phoenix, the famously unfinished manga from Osama Tezuka that ran between the 60s and 80s, was adapted in 2004. Why did it have so long for these titles to get anime adaptations?

Genuine Dubiety

The reality is that information technology'southward incommunicable to determine a single reason why every anime that takes a while to be given an anime is properly adjusted. Often, in that location are troubles and difficulties behind the scenes that delay projects and adaptations. JoJo's Bizarre Run a risk famously had an anime movie that was almost released, but which was shelved and never distributed due to it being absolutely horrible.

Therefore, the following reasons are theories equally to why some anime have never had farther adaptations rather than being all-encompassing descriptions. These are simply the 2 biggest reasons why some manga just have problem making it to the big screen.

The Popularity Problem

Many anime are adapted in social club to either capitalize on the manga'south recent success or advertise the ongoing manga. Demon Slayer very famously popularized its manga to the point where it briefly overtook Ane Slice as Shonen Jump's acknowledged championship. Even so, for many manga -- peculiarly ones with mature themes -- there's fiddling point in marketing to a broader viewership because the audition is incredibly niche.

Devilman is an odd inverse of this. The original manga received multiple anime adaptations but for many years, its almost pop iteration in Nihon was a child-friendly series from the 70s. Western audiences might have been introduced to the title via the 90s' gory OVAs, but these adaptations capitalized on nostalgia established by the original serial and original manga, not equally a means to promote the manga, as is more often the case. Even then, Devilman Crybaby helped bring the Devilman manga into a new phase of popularity, particularly amid Western audiences.

Compare that to Assistant Fish, an adult serial about crime, violence and homosexuality. While the manga sold 12 million volumes, many telly stations likely didn't want to take a take chances on such a mature belongings. Banana Fish was only adapted as a part of manga creator Akimi Yoshida's fortieth anniversary as a manga creator. Many manga are adapted as a consequence of legacy adaptations but aren't adapted until the mainstream culture of television set stations and audiences are more receptive to the more controversial elements -- in this instance, overt homosexuality and sexual assail on mainstream tv set.

Censorship at the Time of Release

Many of these anime that received later adaptations had two cadre bug: either the animation would be too difficult to recreate without an appropriate budget or television standards at the time of release would have kept it from being a mainstream hit. Shows like Interspecies Reviewers encountered heavy censorship upon release. How, then, would the censors react to seeing the violence in Devilman adjusted to television?

The OVA nail helped mitigate this by providing anime that were spared going through the censorship system. This is why some anime, like Devilman and JoJo'south Baroque Hazard, saw brief OVA adaptations in the 90s. All the same, these oftentimes received lower budgets and usually just adjusted a small clamper of a larger story. Past this logic,Assistant Fish, which depicted far more taboo subjects, would have been cheaply adapted as an OVA that could not tell the whole story. A show like Parasyte, which would require a higher budget to breathing all that torso horror and a long length to tell the full story, would not work as a brief OVA in the aforementioned manner it does equally a total-length series.

Information technology is for this very elementary reason that plenty of successful manga received anime adaptations many years later; they had a niche audition that could not be marketed to via mainstream anime television. However, as time passed and college budgets have been issued to more than mature works, this problem has been mitigated to at least some caste.
