We a Group of anime community requests all the animation studios to make a reboot of Zatchbell (Gash bell) as it was one of the legendary and best Anime. There's is still a high response from the anime community about zatchbell and people are even still watching it and the manga which was 12 years ago ,we still find our hearts in zatchbell and no other anime have took place .

Zatchbell was a popular franchise in Japan when it was around. It was as, but honestly more, popular than Fullmetal Alchemist and HunterXHunter were before those both got remakes (in Japan - things are different in the US). Look at what kind of video games and movies ZB got while it was going on, and then look at what those two franchises got during their original anime adaptations. Not as much, and that's not even counting the hugely successful card game (once again, in Japan).

So it used to be popular, that's already good. But the franchise is also well-remembered and stuff is actually happening with it. The manga was rereleased as ebooks on Amazon.jp starting last year (with new extra chapters!) and some of them hit the #1 spot for manga ebooks. Raiku initially said these ebooks would not receive a physical printing, but they are now getting one presumably because the ebooks sold so well. It will be the manga's fourth complete rerelease.

The original Zatch Bell! (Konjiki no Gash Bell!! in Japan) anime stopped before the manga version was ever finished, and so the original anime was never finished as a result.

The original anime stopped at episode 150 (season 3) during the "Faudo Arc", and so the "King's Festival arc" never got to see the light of day in anime form (which was a real shame).

Unfortunately because of the Faudo Arc being very different in the anime from the manga version, the anime most likely would have to be made from start again, so a remake or reboot would have to happen instead of just continuing from where the anime series left off.

I'm pretty sure the series creator (Makoto Raiku) was extremely disappointed that the anime was never finished and that the Faudo Arc was very different in the anime compared to the manga. And I'm pretty that he wishes that he could someday see a anime version of his creation that directly follows it from start to finish.
