As far as I know, Bleach have several productions like light novels, manga, anime, animated movies and even a Live Action. Different franchises treat differently different productions, so in some franchises for example, animated movies are canon and in others are not, and even in some like Dragon Ball some movies are canon and others are not, and some series are canon and others are not. How does this work in Bleach?
Which Bleach productions are canon and needed to understand Bleach: Thousand-Year Blood War?
