In 24th place is that guy in his childhood, the ideal king Kid Gil-kyun. Don't call him "kyun."
Blond hair and red cat eyes... which recalls a certain True Ancestor princess. Honestly, he seems like he'd get along well with Neco-Arc. (because her thought pattern is "rich people = total supremacy")
His magical energy is somewhat low in his child form, so he cannot summon large numbers of Noble Phantasms, but in exchange he wields them skillfully. In other words, he lacks the Skill: Arrogance. ...Wait, doesn't that make the child version stronger!?
