レオン・ウィステリア

Prince of the Kingdom of Wisteria and Alice's younger brother. Originally he was the only one who had the first right to the throne. His body is weak, but he is intelligent, so he's been assisting his father, the king, at a young age. Perhaps because of this, he has a calm and quiet personality for his age, but he has a tough attitude towards Alice. [Translated from official website]
