Charles' is a bold, and sociable player with excellent passes on the field, earning him the title of The Heart of France. He's alert and responsive, charismatic in his replies and can get along well with anyone. Charles comes across as childish and disrespectful, best shown when he tries to sneak away during Loki's lectures and, when called out, covers his ears. He seems to show little to no interest in learning the concepts and frameworks behind soccer, and prefers to "play it by ear" instead.
