There are no plans for Tales of Arise to receive an anime adaptation. In an interview with Famitsu, Tales of series and Tales of Arise Producer Yusuke Tomizawa revealed that the title will not receive an animated adaptation despite several Tales of titles receiving anime adaptations in the past. This has included Tales of Symphonia and Tales of Abyss. Recently, Bandai Namco made episodes of Tales of Abyss available to watch entirely for free through its official YouTube channel. [Thanks, Famitsu!]
That said, this is what Tomizawa had to say regarding a Tales of Arise anime adaptation:
Since so much of Tales of Arise was created around the basis of it being a game, such as the story and overall experience. We have no intentions to tell that same story through an animated adaptation.
He went on to mention the new introduction video by ufotable. The introduction video includes animated segments of various points in the story. Additionally, it shows off several key characters that appear throughout. The introduction video came after the release Tales of Arise. However, Tales of Arise does feature an animated opening by ufotable.
Tales of Arise is available for PlayStation 4, PlayStation 5, Xbox One, Xbox Series X, Xbox Series S, and PC.
