In short, we doubt that Absolute Duo Season 2 ever happen, yet we don't rule out the renewal, completely. We know that you are frustrated. Nonetheless, you should confess that it's better to know the truth rather being in delusion.
First, it's worth noting that Absolute Duo is a kind of mediocre anime. On MyAnimeList, an overall score of Season 1 is 6.73/10 based on about 170,000 votes. Yet this is not a reason to cancel the series. The more vital indicator is all about source material. As you know, Absolute Duo is based on a Japanese light novel of the same name, which consists of eleven volumes. The latter was issued in 2016, and this is a very bad signal.
The reason of such a long hiatus is that there is nothing actually to adapt. The 1st season of Absolute Duo has covered the entire light novel series. As a result, there is no source for Season 2. Finally, let's take a look at the BD/DVD sales of the Absolute Duo franchise. Looks like the figures were weak, or even the worst. Only 818 BD disks were sold between June 1st and 7th of 2015, as well as 278 DVD items. We thereby can't regard Absolute Duo as a commercially successful anime.
After all, 8bit is the studio, which is not the one that might boast renewals. As a rule, 8bit releases the one-cour anime series that later have no Season 2. Summing up, we doubt that we might ever see Absolute Duo Season 2, unfortunately. Of course, you as a fan may doubt and argue on the subject, besides, there are a lot of media outlets that promise Season 2 and even "know" the exact release date for the "upcoming premiere." Yet sadly all these reports are nothing but fake news. Therefore, we suggest you to come to terms with the fact that you'll never see Absolute Duo Season 2.
Nevertheless, there still remains a chance for renewal if Netflix or any animation studio pays attention to Absolute Duo. In such a case, we might keep hoping. Yet we honestly doubt in such a positive scenario. In any case, we are tracking down the official sources. If the 8bit studio announces Absolute Duo Season 2 someday, we will update this page. Stay tuned for updates. We'll keep you informed.
