<p>The boy who approached Ziel and the others was a demon race. He was the Prince of the Demon Kingdom, Viron Parphial. He had a handsome face and an athletic body. The academy students had seen him with King Redis when they had breakfast in the garden behind the castle before. Prince Viron didn't come alone to that place. He was with his sister, Irene Parphial, and several demon race boys who looked like his subordinates. They arrogantly walked up to Clara and her group. Among them, only Princess Irene looked humble.</p>
