In fact, Devilman Crybaby is another reboot of the eponymous franchise, which started yet in 1972. Therefore, the good news is that there is enough source material for other television adaptations of the original Japanese manga series by Go Nagai. Moreover, Devilman, in turn, is a prequel to Nagai's previous manga series, Demon Lord Dante. As a result, we might conclude that Devilman Crybaby has been just another attempt to revive the recently successful franchise. Of course, this factor plays in favor of renewal.
Another significant detail is that Devilman Crybaby has received the incredibly high score among the viewers. The anime has a rating of 8.16/10 on MyAnimeList based on ~ 33,500 votes. On IMDb, the adaptation has a score of 7.8/10 > 1500 votes. Many critics have positively evaluated this anime as well. Thus, in general, both critics and viewers were satisfied with the new product by Netflix.
Finally, Devilman Crybaby is apparently the flagship of the current winter anime season, excepting maybe only Overlord. But we should note that Overlord is an experienced competitor, its second installment has a rating of 8.35/10 on MAL. By the way, the previous incarnation of Devilman titled Cyborg 009 VS Devilman is still successful in the BD/DVD sales. As a result, we foresee the success of the new adaptation as well.
The appearance of Devilman Crybaby most likely points out the beginning of competition between Netflix and Crunchyroll and Funimation since the global content provider has invaded their territory. It's unclear so far how they would divide the market. But it's evident that Netflix isn't going to give up. So, it seems that we would observe the global changing in the Western world of anime soon. Netflix has become the standard of quality. Therefore, all these changes will play in favor of the viewers (consumers for Netflix). Also worth noting that according to Bloomberg, Netflix is going to spend $8 billion, to extend their programming slate. Noteworthy that anime stands in the second place in the row of their primary tasks.
Devilman Crybaby premiered on January 5, 2018, globally on Netflix as an original series. The Science Saru studio served as a developer of the television adaptation. The first season of the anime consists of ten episodes, 25 minutes each. As of now, there have been no official announcements of Season 2.
Summing up, we conclude that Devilman Crybaby has all the chances to return for a second season on Netflix. All indicators play in favor of renewal. All we need is just waiting for the confirmation of this assumption from Netflix. However, in our opinion, the decision will be following soon.
