>>23517669Most things that aren't necessary to explain/explore in these games are implied, largely due to the constrains of the game and the tone of the games. It's pretty much safe to assume if something is heavily implied, that it's true. That's why the manga and anime are effective though, as it lets them explore concepts like Clefairy's origin which would otherwise bog down the games.
