Roen is a good friend of Rassius Luine, but they have always shared a certain rivalry, primarily because of Roen. The two were also good friends with the Princess of Inferia, Arende, but at some point, Roen developed romantic feelings for her and even courted her. However, Arende fell in love with Ras, who did not return her feelings but enjoyed her company as a friend and talked with her about his problems, worries, and plans. Roen therefore often felt neglected by Arende but nonetheless looked out for her well-being. Over time, Roen became a recruit in the Royal Army, then soon rose to Captain of the Royal Guard. As such, he spends most of his time in Inferia City, while Ras travels the world.
