Toriyama commented on the film:
This Dragon Ball Super film is the next story after the currently airing television anime. The story takes place after the climax of the Tournament of Power, where the fate of the universe was at stake, and the short rest that follows. It will give a few previously unwritten details about the Saiyans and Frieza, as well as a long-awaited strong opponent to overcome, and I think it will be an enjoyable story!Last edited by UltimateGamer1982 - on 19 May 2018
From 2013's Battle of Gods and the last film Resurrection 'F' to the current film, I've been carefully writing, and I've had the pleasure of drawing lots of designs and the like. I'm actually as busy as ever, but while I don't have to serialize anything I have time to think about the anime, which used to be out of my hands. (laughs) So please look forward to it!
By the way, the television anime is over for now, but Toyotarō's popular manga (five volumes out now!) is continuing. I think it will have different developments from the television anime and film, so please look forward to it. I certainly will!
