Warning: Spoilers for Black Clover: Sword Of The Wizard KingNetflix's Black Clover: Sword Of The Wizard King movie features many tie-ins to Yuki Tabata's ongoing manga. Although Netflix announced that the film isn't canon, this is contradicted by the fact that there are events from the manga that clearly influenced its overall storyline, which is set before Asta and the Black Bulls' journey into the Heart Kingdom. It would be more correct to say that Sword of the Wizard King is a standalone story that doesn't affect future events in the manga, but that does not mean that there are no tie-ins.
