The third season of Sword Art Online is called Sword Art Online: Alicization. There was a spin-off anime, titled Sword Art Online Alternative Gun Gale Online, that had been announced in 2017. Sword Art Online Alternative Gun Gale Online was animated by 3Hz. The anime premiered on April 2018. Now, if we talk about Sword Art Online: Alicization. The anime aired from October 6, 2018, to March 30, 2019. There was a one-hour world premiere which aired in Japan, the United States, Germany, France, Australia, Russia, and South Korea on September 15, 2018.
The English dub of the third season premiered on February 9, 2019 on Toonami. Sword Art Online: Alicization was announced to air for four cours which is close to 50 episodes. The anime was supposed to adapt from the ninth volume, Alicization Beginning, to the eighteenth volume, Alicization Lasting.
However, the season ended before that with episode 24 on March 30, 2019. They only completed the fourteenth volume of the novel, Alicization Uniting. So, the anime is actually to continue a few months later. Sword Art Online: Alicization will come back for its second part which is titled, War of Underworld in October 2019.
There is a good deal of confusion among the fans because of the break. But, there won’t be another season of Sword Art Online. At least not yet it hasn’t been confirmed that there will be another season of Sword Art Online. What we do know is that the show will return for its second part of the third season. The second part will most likely consist of the same number of episodes. So, we can expect around 24 episodes, or they can increase it to 26, to hit that 50 episode mark.
We can also expect to see a new opening and ending theme songs for the second part of Sword Art Online Alicization. The studio and the staff involved with the series will remain unchanged until any further notice.
