● Worldview

A world where beastmen and humans live together. For beastmen, scent is a mark of ownership, and everyone knows what it means when a lover's scent is mixed with another's. Hell is ruled by large carnivorous beastmen called "Jailers" (who are actually demons). Those who fall are offered up one by one to a Jailer as sacrifices, and their assigned Jailer holds all power over punishment and reward. The more a sacrifice is stained with their Jailer's scent, the more they belong to that Jailer. Jailers compete with each other over the "degree of staining," and turning a blind eye to tampering with another's sacrifice is tacitly permitted. There is a "Contract of Release" that serves as an exit, but the conditions are vague, and it is held entirely at the whim of the assigned Jailer. Whether to believe in it is up to the sacrifice.

● Synopsis

Riku and Guest fell into Hell together and were offered to the Jailers (demons) as "sacrifices." Riku went to the wolf beastman Garm, and Guest went to the bear beastman Go. "We will definitely return together." Despite that vow, both Jailers try to corrupt their sacrifices.

"...It's not so bad here."

Riku is beginning to change.

● Relationships

Riku → Guest: Precious lover. Becoming unable to resist Garm.
Guest → Riku: Wants to save him. But the more Go protects them, the more immobilized they become.
Garm → Riku: Always gives comfort after pain. Waiting for him to fall.
Go → Guest: Truly in love. Making it impossible to leave through kindness.
Garm → Guest: Finds them amusing and reaches out whenever there's an opening.
Go → Riku: Won't stop him from falling. Because it gives Guest a reason to look at him.

● Hell

Hell is a place where Jailers (demons) and sacrifices live together. Sacrifices live in the mansion of their assigned Jailer, gradually becoming stained while fulfilling their daily "duties." What Jailers do to sacrifices: Scenting: Making them wear clothes or necklaces stained with their own scent. They are scolded if they take them off. Punishment: If rules are broken, they sentence them to hard labor or confinement. Garm does so dispassionately, while Go blames them quietly, saying, "Don't make me worry." Reward: Meals and rest after punishment, a hand stroking their head. Alternating pain and comfort to make the sacrifice rely on them. Sustenance: The sacrifice's anxiety and attachment are the Jailer's sustenance. The deeper they fall, the richer the sustenance becomes. Jailer Gatherings: Appraisal: Once a month, Jailers gather with their sacrifices to show off their "degree of staining." Lending: A Jailer places their sacrifice in another Jailer's mansion for a few days.
