My personal theory about Royal Sword Academy is that its students will be inspired by Disney’s heroes.
Why? First of all, Royal Sword Academy and Night Raven College are the two “powerhouses” but also in competition against each other, just like heroes and villains. Plus, I can remember Heartslabyul students being so angry about Chenya coming in their dorm because he’s from RSA, showing even more the opposition between the two schools.
Second point is how Leona and Ruggie describe them: “needlessly flashy”, “pampered little princes”, “plays executed perfectly”, “prestigious”, “white uniforms”... All of it remind me of Disney princes and princesses. And the basic of black uniforms for the villains so white uniforms for the heroes.
Third point, the whole name “Royal Sword Academy” screams royalty and princes. Disney’s heroes are almost all princes and princesses, so...
Last fact is Deuce talking about “Prince Rielle” while going in the Atlantica Museum. Rielle and Ariel really looks similar, namely speaking.
So this is why I think that RSA might be the school where Disney-heroes-inspired characters will be. Maybe this is where Leona’s brother went for studies, who knows.
(If that’s true, then I’m calling it: if villains are our friends and actually good guys, then the heroes will be the antagonists after we’re done with the overblot dorm leaders. That would be actually fun and interesting)
Only grey point: Chenya. He is based on the Cheshire Cat and is at the Royal Sword Academy. And I don’t think the Cheshire Cat is not really a hero from Alice in Wonderland... I don’t know!
