Leona Kingscholar

Leona Kingscholar is a third-year and the leader of Savanaclaw. While he has great magic powers, he doesn't like using much effort, and constantly appears lax and leisurely. He's the second prince of his home country and acts arrogantly towards everyone. Though Leona is clever and possesses powerful magic abilities, his reluctance to put forth any significant effort into his studies (missing important final exams) resulted in him repeating two school years. He has an older brother named Farena, who he describes as being rather carefree. His son Cheka is Leona's nephew, and is very attached to Leona.

Leona's Unique Magic is "King's Roar." After doing a small chant, anything he touches turns into sand.
