The original Hell's Paradise manga was first published in Shōnen Jump+ in Japan starting in late January 2018. It was written by Yuji Kaku, who previously worked with Chainsaw Man author Tatsuki Fujimoto on a manga called Fire Punch.

As with most anime series, they are typically adapted from an existing manga, whether or not the source material is over. It's all too common for an anime to adapt an ongoing manga, though whether or not it will adapt the whole story is a separate issue entirely.

However, there are some exceptions where the anime adapts a manga that has already finished. Hell's Paradise finds itself firmly in that camp.

The Hell's Paradise manga ended on Jan. 25, 2021 after 127 chapters. At this point, the manga has already been collected into 13 volumes, all of which were officially released with English translations by March 2022. Not only is the manga finished, but you can head down to your local bookstore and catch up on the series already!
