If you want to say something is ‘canon’, don’t solely base it off of the anime, especially the dub.
Sometimes, they add extra things in the dub to make English speakers laugh or something. It’s not something to be taken seriously.
I saw a post saying that France and England were canonly gay because the movie said 'they love each other sexually’. And that my friends, is Funimation adding in some things to make English speakers laugh. That is not to be taken seriously.
But always take the manga seriously. It’s made by the original creator so unless they put a disclaimer for a certain part, everything is obviously canon.
