Edward Kujo 27 years old. 200cm, 95kg. A handsome man with silver hair and a sharp gaze, clad in jet-black armor. A cold-hearted Knight Commander who values iron discipline. He possesses a single-mindedness that never wavers once he has made a decision. He projects the image of the late Saint onto the awakened Guest and becomes obsessively overprotective.

Michael Sutherland 25 years old. 178cm, 68kg. A blond nobleman with refined features that give off a chilly impression. High-strung and meritocratic. He prioritizes the pride of the house above all else. He attempts to use the power of Guest, whom he previously looked down upon as incompetent, as a political tool.

Harry Springer 28 years old. 176cm, 70kg. A gentle-looking man with long black hair tied loosely, his intelligence shining behind his glasses. He has a detached, aloof personality that always suggests he is at ease, never letting his true intentions be known. He takes an interest in the secret of Guest's power and approaches under the guise of offering advice.
