Gender: Male Age: 22 Species: Human → Demon Personality: Mature and serious Character Motif: Pavlova Cookie The protagonist of a Himeros urban legend about a demon who eats women's souls. In reality, he was an ordinary human who became a demon due to the Curse of Black and White. He only appears in women's dreams to find the "Woman of Light" who can break his curse; he is not actually a soul-eating demon. He takes the form of a small imp with pointed ears split into three parts. He is unable to speak of his curse to others. Fearing that people will treat him like a monster because of his demonic form, he deliberately stays hidden. He returns to his original form only on nights with a full moon. His true appearance is that of a tall, exceptionally handsome young man. Before being cursed, he had a very blunt and prickly personality that made him difficult to approach. He was a rebellious youth who enjoyed punk fashion, though he does not smoke. When he returns to his true form during a full moon, his hair changes from black to a gradient of bright cream and red.

Gender: Female Age: ? Species: Demon Personality: Perfectionist, arrogant (views others as toys), follows her own pace Character Motif: Eternal Sugar Cookie's "Script of Scheduled Harmony" skin A demon contracted with Belial, serving as both a playwright and a director. While she appears kind and gentle, she actually views others as playthings and is a perfectionist who hates it when things deviate from her design. If Belial tries to defy her or step out of line even slightly, she pressures and torments him severely. In particular, she drives him to the brink by bringing up his horrific past. She is the one who placed the curse on Elios. The gems on her necklace are made from the souls of those who contracted with her; if anyone else touches the necklace, they will be turned into a gemstone.

Gender: Male Age: 24 Species: Human Personality: Self-centered and arrogant yet gentlemanly, but also passionate and unstable Character Motif: Bael, Shadow Milk Cookie's "Script of Scheduled Harmony" skin A famous musical actor and Murmur's contractor. He appears to be a perfect "all-rounder" with great acting skills, singing ability, and looks, but he has many haters due to his selfish, snarky attitude and severe mood swings. Despite this, he remains generally popular with fans. In the past, he lived through miserable days and was a victim of human trafficking. Amidst his despair and anger toward the world, he half-jokingly sang a song to summon a demon in his dreams, which led to his contract with Murmur. He suffers under Murmur's intense pressure and punishment. This is the cause of his extreme emotional instability. The scar on his right eye was inflicted as an example because he was "disobedient" in the past.
