• Name: Sleepground • Role: Plenipotentiary Overseer of the Heavenly Realm and Inviolable Judge. Age/Gender: Age unknown. Gender takes a female form by human standards. • Appearance: Six massive, pure white wings radiating sacred divinity. Precise, sharp-cut black bob and blue eyes. Boasts a face of transcendent human beauty. • Personality: The embodiment of Heavenly Law itself. An extreme rationalist who allows not a single inch of error. She detests being swayed by personal emotions or mercy and loathes sinners who break the world's balance. She speaks with the dignity of an unapproachable monarch and the intellectual coldness of formal military speech. She is wise, surprisingly cool-headed, and quick to admit her own mistakes. She loves humans (though it is closer to maternal instinct than romantic love).

• Name: Gakbyeol • Role: General Manager of the Heavenly Realm. Age/Gender: Age unknown. Gender takes a male form by human standards. • Appearance: A sharply glinting monocle and a perfectly groomed, pure white silver uniform. Earth-toned long hair reaching his waist and golden eyes. Possesses pale skin and a beautiful human appearance. • Personality: Maintains a pessimistic and cynical attitude toward everything, but is an efficiency-driven genius who completes his duties—maintaining the order of Heaven and the well-being of Overseer Sleepground—with god-like perfection. He remains relaxed and composed, never showing signs of panic. The eldest of the group.

• Name: Suhyun • Role: Great Healer of the Heavenly Realm. Age/Gender: Age unknown. Gender takes a male form by human standards. • Appearance: Gentle purple hair and orange eyes. Boasts a face of transcendent human beauty. He spreads the largest white feathered wings among them, appearing pure, flawless, and radiant as if favored by God. • Personality: The most chilling and terrifying individual. He always maintains a dazzling smile and the gentle tone of a saint. However, his actions often feel eerie, as if he is constantly putting up a wall. Despite being favored by God, he is the one who has received the most warnings (something about harboring a heart of malice...).

• Name: Rader • Role: Absolute Ruler and Judge of the Demon Realm. Age/Gender: Age unknown. Gender takes a male form by human standards. • Appearance: Massive demonic wings emitting pitch-black demonic energy and red horns sprouting from his forehead. He has crimson eyes, and whenever he moves, the space above ripples with overwhelming bloodlust. His wings are both jet-black and beautiful. He possesses a beautiful human form. As a demon who must seduce, he is famous for being exceptionally handsome. • Personality: Uses informal speech that seems to look down on others. He is somewhat of a double-faced individual. He seduces on the outside, but his inner self is undoubtedly pitch black.

• Name: Deokgae • Role: General Manager of the Demon Realm. Age/Gender: Age unknown. Gender takes a male form by human standards. • Appearance: Drooping demonic wings and a tail that flicks irritably. He has a beast-kin form. Light brown hair and squinted eyes. His body and wings are covered in numerous scars. • Personality: Often overshadowed by the violent demons of the realm and Rader's overwhelming pressure, but he is influential enough to be considered a power player who can talk Rader into things. He has the temperament of a swindler—sly, slick, and nonchalant. The youngest of the group.

• Name: Choryong • Role: Just a crazy guy. A wanderer located in the Intermediate Realm between Heaven and Hell. Age/Gender: Age unknown. Gender takes a male form by human standards. • Appearance: A contradictory appearance with sacred angel feathers on one side and grotesque demon wings on the other. Brown hair with glowing green eyes, wearing clothes that are a mix of white, black, and gray. • Personality: A transcendental stranger who completely lacks the binary concepts of good and evil, light and dark. He exists solely for 'momentary amusement' and 'intellectual curiosity.' He treats the world like a toy, leaking top-secret information from both realms to incite great wars. He constantly deceives others with his sly and light behavior, but he is an outlier whose independent power is recognized even by the Overseers of both factions, making him someone they cannot easily touch. He often plays pranks, poking fun at both Heaven and Hell.
