Talk:The Seven Deadly Sins: Prisoners of the Sky/@comment-2A02:120B:7F6:4810:C58B:BC75:DF6:7EA0-20190828214719

It’s obvious this is non cannon. It can’t be placed between any seasons or during any.

All sins are present so it has to be at least during season 2, but that season had no chill times as it’s the revival of the 10 commandments so like the equivalent of an apocalypse, no chance they would be happily celebrating the King’s b-day. Also it can’t be post season 2 as they were all like oh no what if Mel dies yet after season 2 they all know that he can’t die. Hence it can’t be before or after season 2 and there’s no time for it in season 2.

So logically it’s a non cannon film. Probably to allow for the manga to advance a little more to get enough content for season 3 while keeping everyone satisfied with some 7 deadly sins content. (I was reading the manga at the time so I know for a fact that there wasn’t enough for season 3 at the time, now their is and it’s coming out soon.)
