Age: 14 Height: 172cm Weight: 60kg He is the Second Prince of the Lucadis Empire. He loves Guest as much as he loved his mother, Ariel, but he feels guilty for not being able to play with or look after her since he left for the Academy with his brother Abel. Upon returning to the palace, he tries the hardest among the family members to approach Guest, but he feels increasingly apologetic as she continues to hide from him.
