Since there has been no official news on the subject, we must rely upon the authority of Crunchyroll. Scott Green refers to Yaraon Blog where we can find the confirmation of this announcement. Indeed, they point towards iQIYI, the leading Chinese streaming service. However, already in his next article, Scott notes that, in fact, there has been no official confirmation on this matter. In any case, we consider this announcement as good news.
The worst thing that might happen is that it will be the second cour of Season 1. As a rule, one cour consists of 10 to 14 episodes that usually run during a three-month period. The first season of Saga of Tanya the Evil consisted of 12 episodes. Perhaps, NUT has released just the first half of the season. Thus, we will have to wait a bit until the announcement of the second cour or second season.
We tend to think that the Chinese source tells us about the remained fourteen episodes of the first season. But we would be happy as well as you if they're talking about Saga of Tanya the Evil Season 2 (if the source is reliable). However, we'd prefer to trust the Japanese sources instead.
The military anime started off in January 2017 in Japan. The series adapts the eponymous light novel by Carlo Zen. Season 1 of the anime was a success, given the statistics by MyAnimeList, 8.16/10 ~ 88,000 votes. The viewers of Crunchyroll gave a score of 4.5/5 stars to this series. The first season (cour) has come to an end on March 31, 2017. By the way, the wiki page of the anime also claims that the anime has got the second season. But you should take into account that they didn't provide a link to the source.
What's The Series About?One guy refuses to believe in the existence of God. He rejects the afterlife as well. However, he must come to terms with this fact when he dies. The mysterious Being X, calling himself God, decides to punish this man for his skepticism. Even standing in front of God, the man is continuing to doubt the concept of the immortality of the soul and reincarnation. As a result, he found himself reborn in the body of a girl, Tanya Degurechaff.
Later, the story continues in the world similar to WWI Europe. According to the prescription, Tanya must die a natural death. Otherwise, she will rot in hell, while atoning the sins of her past. In an attempt to avoid the punishment, Tanya enlists the military service into the Empire's Mages Division. Her primary goal is to escape the possible death on the battlefield. To achieve that purpose she will have to climb in the military table of ranks as high as possible. Thus, Tanya turns into a ruthless soldier, who is going to wipe out any obstacle on the way. She dominates upon the inferior soldiers and severely punishes those who dared to disobey. Because of this, Tanya has a nickname, the "Devil of the Rhine."
