Ewen is a young boy with light skin and an elongated head. His hair is light and combed back. When his hair is down, it reaches about chin-lenth.
Like all other male students, he wears Eden Academy's uniform—a black button-up shirt with black shorts. He wears long white crew socks with black shoes.
During their mornings on their way to Eden Academy, he typically holds another bag in his arms along with the schoolbag on his back, likely to be Damian's bag.
He often suggests Damian needs to work on his vocabulary or grammar.
Ewen quickly become friends with Damian Desmond and Emile Elman, praising Damian and commenting that he will become Imperial Scholar in no time. Learning that Anya is nobody, he and Emile quickly push her away to not spread germs on Damian. As Damian picks on Anya and she punches him, Emile and Ewen tell the teacher, but Anya denies it, saying that Damian walked into her hand.
