ONA
Description
Luke is an angel from the Celestial Realm who participates in an exchange program between the three realms, arriving in the Devildom alongside the angel Simeon. Despite his youthful appearance, which resembles that of a ten-year-old child, he is actually over one thousand years old. He has light blond hair, a fair complexion, and blue eyes with a yellow gradient, and is notably short in stature. His birthday is July 15.

Luke’s personality is boisterous, opinionated, and highly outspoken. He holds very strong views and does not hesitate to express them, especially his distrust of demons. When he first meets the main character, he warns them never to trust a demon, and he frequently clashed with the demon brothers. He is often described as chatty and quick to exasperation, which makes him a source of comedic relief in the story. However, beneath his prickly exterior, Luke is genuinely caring and has a big heart. Simeon describes him as honest and genuine, and he values his friendships deeply. His motivations are rooted in his angelic upbringing, which emphasizes righteousness and order, but he also struggles to reconcile his strict views with the reality of the Devildom.

Luke’s role in the story is that of an exchange student and a side character who provides both worldbuilding and lighthearted moments. He is also a central character in the game Obey Me! One Master to Rule Them All, where players can interact with him through an intimacy system. His presence highlights the tensions between angels and demons, but over time he becomes more integrated into the Devildom society.

Key relationships include Simeon, who acts as his strict but caring supervisor; Barbatos, who teaches him how to cook and with whom he shares a close bond; and Beelzebub, toward whom he shows unexpected friendliness. His relationship with Lucifer is particularly prickly: Luke used to admire Lucifer when he was still an angel, but now strongly dislikes him, especially because Lucifer teases him constantly by calling him nicknames like Chihuahua, Fido, or Dog. Luke also interacts with Mammon and other brothers in ways that often frustrate him but also lead to amusing exchanges. Over the course of the story, Luke undergoes noticeable character development, becoming more open and less rigid in his views, and he eventually forms genuine friendships despite his initial hostility.

One of Luke’s notable abilities is his skill in baking and cooking, which he has practiced for about two hundred years. He enjoys making sweets and has a particular fondness for Simeon’s pancakes and Barbatos’s signature cake. As an angel, he also possesses inherent celestial abilities, though the full extent of his powers is not elaborated upon in the main narrative.
