In battle, Roland is a serious, capable and deadly opponent, willing to use many means to defeat a threat. His self-awareness is revealed when he is confronted by Olivier about the consequences of his changing beliefs towards vampires, and he is slightly apologetic, although only for a brief moment. Despite this, he is actually quite intelligent and casually manipulates situations to his will, as seen when he omits information from reports and when he traps Noé and Vanitas during their first meeting. Roland often acts in a manner that emphasizes a fanaticism with his beliefs and seems oblivious to his surroundings and how his actions and words are regarded by others. This seems to have started accidentally, but has become a bit of a running gag. Roland is sometimes drawn with no eyebrows. His hands are protected by white armored gloves. He usually wears the standard chasseur's uniform, including black pants, a cassock, a pale harness, a dark holster for Durandal, a ribbon-like belt, dark leather boots, and a rosary. Jun Mochizuki has joked that every time she draws him, his physique gets better and his hair gets fluffier. His hair is blond and short, only going just beyond his ears, his bangs cut very close to his hairline.

His face is round with pronounced cheeks and a gently sloping chin large, round, green eyes with long eyelashes and thick, dark eyebrows. Exceptionally well built, he has broader shoulders and a more pronounced chest than nearly all of Mochizuki's male characters. Roland is a fair skinned young man of average height.
