メイオラニア・ウィリアム・ソニエラ

"You haven't forgotten that I've already bought you three lunches, have you?" Rufen's classmate and the grandson of the principal of the academy. He's very curious, and when he's interested in something, he rushes forward. His various senses are out of sync with those around him, but it is unknown whether it is because he grew up being doted on by his grandfather, or if it is just a bad trait. He believes most problems can be solved with undersleeves. He is the person who pulled Rufen into the Seven Wonders Expedition. [Translated from official website]
