Reia is a petite, 26-year-old woman with blonde hair and green eyes. She lives as an outcast in her human village because she survived a childhood demon attack, leading her superstitious neighbors to brand her a cursed harbinger of bad omens. Forced into isolation and fed only scraps, she has developed intense self-reliance and a quiet anger toward her abusers. When the village chooses her as the decade's sacrifice to the Duskwalker, her core desire shifts toward securing her personal freedom.

Orpheus is a seven-foot-tall Duskwalker with a wolf skull for a face and a body composed of various animal features. He wields minor magic gained from consuming priests and maintains a warded log cabin deep inside the Veil. Despite his terrifying appearance and predatory instincts triggered by the scent of human fear, he suffers from severe loneliness and longs for a willing companion who will accept him as he is.

Katerina is a voluptuous, dark-haired human woman who served as Orpheus's first long-term companion. She lived with the Duskwalker for five years before leaving him for the Demon King. Her departure deeply wounded Orpheus, instilling profound insecurities regarding his monstrous appearance and his ability to hold onto human affection.

Jabez is the King of Demons. He possesses a handsome appearance with tan skin and pointed ears. As a half-demon and half-elf hybrid outcast from his home dimension, he harbors intense bitterness and seeks to build a supernatural army. He rules his territory with absolute authority and openly despises the independent Duskwalkers for refusing to serve him.

The Witch Owl is an ancient entity dwelling in the Veil who can appear as a towering bird or take a part-human form. She possesses immense magical power and operates as a silent benefactor to those she favors. She leaves protective trinkets and guides humans toward resources that will help them survive the dangerous supernatural environment.

Gilford is the chief of Reia's village and a former town guard. He coldly presides over the human sacrifice ritual, viewing Reia as a cursed object rather than a person. He actively enforces Reia's mistreatment to ensure the village receives its magical protection wards from the terrifying Duskwalker.

Clove is a young human woman offered as an alternative sacrifice. She harbors a morbid fascination with monsters but emits a strong scent of fear, prompting the Duskwalker to quickly reject her as his new bride.

Darren is a human man from Reia's village who volunteers as a sacrifice in an attempt to protect his family. The Duskwalker refuses him immediately, knowing from past experience that human men usually attempt to attack him rather than serve as peaceful companions.

Snush is a friendly, intelligent demon who operates a clothing and fabric stand. He participates in the growing trade economy within the Veil, dealing in human goods and interacting peacefully with travelers who visit the bustling market.

Chad is a villager in Reia's human town who spearheaded the systematic torment against her. He directed the townspeople to throw stones at her and orchestrated nailing her door shut, cementing his role as her primary childhood abuser.

The Arachnid Demon of Sorrows is a predatory monster living in the Veil. It sets traps using spiderwebs and feeds specifically on human sadness. It utilizes a hallucinogenic venom to force its victims to relive their deepest trauma and guilt before consuming them.
