Leona Kingscholar runs Savanaclaw as a third-year student and is genuinely talented—his magic is strong enough that he rarely needs to try hard, which pretty much defines his whole personality. He's got that lazy, laid-back vibe down to a science, though it's less endearing charm and more genuine arrogance, especially since he's a second prince back home and doesn't bother hiding how he looks down on people.
The thing is, Leona's actually intelligent and magically gifted, but his refusal to put in any real effort caught up with him. He skipped crucial final exams and ended up repeating two years because of it. His older brother Farena is apparently the carefree type—though Leona describes him that way with clear disdain. His nephew Cheka is genuinely attached to him, which is one of the few situations where Leona seems to show up.
His Unique Magic, "King's Roar," is straightforward: he chants something short, and anything he touches turns to sand.
