A prince who became Catarina's fiancé after he inadvertently caused her to trip and injure herself, forcing him to take responsibility. In the game, Catarina uses this to her advantage to monopolize him for herself. In the good ending he exiles Catarina and marries the protagonist, whilst the bad ending has him kill Catarina and abandoning the heroine due to guilt. Due to Catarina's continued efforts to better herself and avoid the bad endings, he now has developed genuine feelings for her and continuously tries to demonstrate his affection by confirming their engagement, however, it is overlooked by Catarina's dense persona much to his chagrin.
