No matter how unsure everything looks, we really cannot come to any concrete conclusion as it's been only two years before fans heard anything related to the anime series.
One of the best things about anime television series is that we get to see the extremes scenarios with full power intensity that is rare, especially if we want to see futuristic effects of disastrous wars that include complex setup of war where heavy use of futuristic technology along with some badass CGI gets portrayed. One of such animes is 'Aldnoah. Zero' that contains all these elements. However, the anime series, of course, shows some cliches including most typical characters that anime lovers find in such mecha genre. Such anime also has its own interesting factors and beauty.
The anime series is produced by A-1 Pictures and animation of ‘Aldnoah.Zero’ is also quite impressive. The action scenes in the anime are very well coordinated and the battle scenes are perfectly shown that makes it even more interesting to watch. The music in the anime is given by Hiroyuki Sawano, who brings some amazing techno beats in the anime that makes it OST different from others. ‘Aldnoah.Zero’ eventually became a controversial anime because of the endless debates on the subject of its future, on MAL and Reddit. However, fans who have been loyal to this show are desperately waiting for the next season of the series. It has been two years since fans saw the conclusion of the last season. They want to know whether there will be another season or not, and even though chances are really thin, let's try to find out the possibilities that will give an idea about what to expect next.
Frankly, not really, as the anime series is not based on any light novel or manga that could help in serving a source for the next television adaptation. In short, if there has to be any renewal, it will all depend on the creator in general and on Katsuhiko Takayama, in particular. Another factor we cannot miss to analyze is the ratings and response both the seasons got from the targeted audience. Looking at the date and figures, it does look that the show performed well by scoring 7.61/10 > 167,000 votes, while the second one has a rating of 7.13/10 ~ 110,500 votes, according to MyAnimeList.
However, fans were not really impressed with the second season as they were with the first season, which makes the entire renewing situation dicey. No matter how unsure everything looks, we really cannot come to any concrete conclusion as it's been only two years before fans heard anything related to the anime series. Two years is not long enough when we are talking about animes as there is plenty of series for which fans have waited for decades and got surprised by the renewal.
Even though the chances are very less for the renewal to happen for the third time if look at the points mentioned above, however, if at all the third installment takes place then we might see it happening sometime in 2021 or 2022. Season 1 released on July 6, 2014, and ended on September 21, 2014, with total 12 episodes. The second season was soon released on January 11, 2015 and continued till March 29, 2015.
Some want it, and some continue to stay disappointed.
