Unsurprising to see. Jigokuraku is a solid anime based on a solid, if not amazing, manga. If you're interested in a supernatural shonen battle anime, this one is one of the better ones. It's better than Jujutsu Kaisen (not that the bar for that is very high since JJK is not very good), is reasonably well paced, has a self-contained story, and ends after a reasonable amount of time. The one thing I don't care for in regards to the anime is pacing. The anime is fairly slow, with each chapter being one episode thereabouts. You could easily fit two full chapters into a given episode, though. Maybe cut out some parts of the manga from the anime, and then have the full series done with over the course of around 4 cours. It seems like every anime today tries to be a shot for shot adaptation of the source material. Which I know the fans generally like, but not everything necessarily translates that cleanly between mediums and the adaptation suffers because of it.
