Easygoing Luxray.
In the games, Galar does things differently by having Gym Leaders compete for the title of Champion to reflect soccer tournaments, whereas other regions make vague mentions that Gym Leaders can face off against the Elite Four and the Champion. Alola had no league to speak of, but Kukui was slowly preparing it and connected it to the Grand Trials as to make their tradition reflect with the league so it'd look homely. He also recruited other people to act as the Elite Four members; some were connected to the Grand Trials, while some others had the strength to prove their worth (Kahili).Galar doesn't have E4 either so does that mean Leon isn't champion of Galar region?
...It's just that the anime really made a mess of the Alola League by making the Grand Trials completely optional attractions without enough quirky mini games. Then it took things to a stranger degree with the PWC where Galarian Gym Leaders are now shiny rivals that are pretty much the cream of the crop inducing the Worf Effect on everyone else (Ash included).
