Prince Aaron is the Prince of the Spirit Kingdom. He has a crush on Ranze.

He is the son of the Demon King and maybe have another sibling lurking among the cast.

He is able to duplicate something he touches, such as when a burger girl asks him for money. He doesn't know what it is, but touches a piece she shows him and pulls a giant pile of it out of thin air from his back pocket.

He is incredibly strong, able to deadlift Tamasaburo Kamiya's car with 1 arm (with him still in it) though when he boxes Shun (who is slightly taller than Aaron) in episode 18 they appear to be an equal match because Aaron refrains from using his magical powers.
