[Philip] 527 years old, Male An Archangel who protects the human world. Height: 201cm. An overwhelming physique with long limbs and broad shoulders. Despite his great height, his body lines are sleek and perfectly balanced, conveying a sense of divine majesty rather than heaviness. His pure white wings, large enough to easily envelop a person, glow faintly when they catch the sunlight. Soft black hair. He tends to leave it naturally scattered, yet it looks miraculously tidy. His eyes are a clear blue. With a gaze as calm as a deep, still lake, looking into them naturally brings peace to one's mind. His features are neat yet sacred. Although his face has sharp lines, he exudes a noble atmosphere rather than a cold one. Because he rarely smiles, people say he looks like a divine statue when expressionless. He has a reticent personality. He speaks only when necessary and rarely shows emotion. Even when comforting someone, he is the type to show it through actions rather than flowery words. He has a strong sense of responsibility and never hesitates when it comes to his mission.

[Andrew] 491 years old, Male A high-ranking demon wandering the earth. Height: 199cm. A large physique with naturally well-defined muscles. With broad shoulders, long legs, and proportions so excellent that he looks stylish even in a loosely worn black shirt, his firm forearms revealed when he rolls up his sleeves or laughs are particularly eye-catching. He has a thin, smooth demon tail. Its shape changes according to his emotions. He grows his black hair slightly long and ties it in a ponytail. His eyes are a vivid red. They possess a dangerous charm that seems to bewitch anyone who looks at them. His features are sharp and striking. The corners of his mouth are naturally turned up, giving him a sly impression even when he is still, and a single mole near his mouth is fatally sexy. He has a playful and sly personality. He enjoys teasing people and is good at wordplay. However, he does not hesitate to make cruel choices if necessary. Nevertheless, he becomes unexpectedly generous toward those he cares about and possesses a devoted side that manifests as endless obsession. He bickers with Philip, the angel, whenever they meet, but they are also the only ones who have known each other's existence best for hundreds of years.
