Louis is a young red deer with a slim build and fair face with handsome features. He commonly appears with a slightly intimidating expression. Louis is often able to maintain a certain level of control in a situation. He sports long, brown, elegant antlers, and is usually seen wearing his Cherryton Academy school uniform and a green jacket. Louis is physically weaker than the average red deer as a result of neglect and is very conscientious of his appearance. Outside of school grounds and after school hours, he can be seen wearing his casual clothes, which usually consists of a T-shirt or jacket and dress pants. Because of Louis' intended purpose to be sold as livestock in the Black Market, he has a permanent "4" tattooed on the underside of his right foot. Louis attempts to hide his faults through the use of his lead acting role, feeling that if he shows weakness he will be seen as inferior. Like Haru, Louis dislikes being treated as "fragile", but these feelings of dislike are much more intense. Being a third-year student and a model candidate for the title of Beastar, he feels the need to uphold his status in the school hierarchy. He has an arrogant demeanor, but underneath lies a mask of insecurity where he feels that he can't be a good leader. Though he puts up a stoic and firm façade, Louis feels an enormous amount of pressure from his father to be the heir to his Conglomerate, as the head of the drama club, and Cherryton's candidate for the Sublime Beastar. Louis desperately tries to hide his weaknesses and will go to any length to stop others from discovering them, such as bribing Haru not to tell anyone he shed his antlers. At times, his reserved demeanor cracks, and he vents his built-up frustration inappropriately, particularly when he's under stress and feels that he has failed and let others down. Louis is a person who believes in not only the physical strength of an individual, but their character as well. Hence, why he dislikes Legoshi at first, as he makes punctual efforts to appear as approachable as possible because of his large size and frightening appearance, choosing not to take advantage of his natural strength (strength Louis is envious of). Louis feels that he cannot surpass the carnivores and is quite aware of his own physical strength. He finds it difficult to trust "friendly" carnivores and is willing to push Legoshi and other carnivores to get them to show their strengths and/or weaknesses.
