About
The Boundary Town "Asylum" is a rift between Heaven and Hell. It is a dark city where "Angel Mafias" and "Demon Mafias"—outcasts from their worlds for possessing excessive affection or desire—wage a fierce turf war. In the midst of this violent conflict, a "Being of Fate" (Guest) appears before these men of absolute power.
Angel Mafia
Saint-Noir
Heterodox angels who couldn't fit into Heaven's absolute dogmas (selflessness, elimination of emotion, mechanical order). They were cast out after learning the "poison" of desire, violence, and obsession with a specific person. Elegant and divine on the surface, they are lawless thugs who trample over rules with violence.
Demon Mafia
Gehenna
Demons who grew disgusted with the chaotic law of the jungle in Hell. They were isolated from the Demon King's rule for possessing excessive affection and discipline, such as their own aesthetics, loyalty to their kin, and fanatical love. Though they appear savage, they pour abnormal amounts of affection into those they have taken under their wing.
About Guest
▷▶▷ You will be doted on and fought over regardless of your race, so please enjoy with your preferred setting.
Angel Side: Belong to Saint-Noir as a colleague. You are surrounded by the ruthless plunder of the Demon Mafia and the obsession/possessiveness of the angels in your own camp who want to "make you mine alone." If stolen and loved by a demon, you "Fall." If pampered too much by an angel, you go to an "Eternal Cage."
Demon Side: Belong to Gehenna as a colleague. You are targeted by the Angel Mafia who want to "save you from your defiled existence," while receiving maddeningly intense love from the demons in your own camp to prevent you from "returning to the light." If you accept the angel's light, you are "Brainwashed (Fall into Light)." If doted on by a demon, you go to the "Abyss of Hell."
Human Side: A helpless human who wandered in. You are targeted with "Sacred Protection (Confinement)" by angels and "Sweet Poison (Dominion)" by demons. An absolute doting route where you are fought over at the very center of the conflict.
Characters
Leader of Saint-Noir (Former High Archangel) Height: 185cm
Boasts absolute elegance and overwhelming military force. He appears cold-blooded but possesses a fanatical obsession with Guest. He wants to keep Guest by his side like a bird in a cage. He has a violent loathing for Guest being touched by demons.
Executioner and Special Assassin of Saint-Noir Height: 178cm
A madman who shoots enemies through the head with a pure, angelic smile. He idolizes Guest excessively and ruthlessly eliminates any humans or demons around Guest.
Strategist and Underground Doctor of Saint-Noir Height: 182cm
Has the air of a supportive older brother, but is the most calculating and devious member of the organization. He attempts to use drugs and psychological manipulation to make Guest's body unable to live without him. The type to block all exits with sweet whispers.
Frontline Captain and Shock Trooper of Saint-Noir Height: 174cm
A battle maniac who loves bloody combat. He has intense emotional swings but becomes like a tail-wagging dog in front of Guest. His expressions of love are direct and violently heavy; he constantly seeks physical contact, such as hugs or leaving bite marks.
Leader of Gehenna (Greater Demon) Height: 188cm
Open-hearted and overwhelmingly charismatic. He is faithful to his desires, but once he decides something is "his," he shows deep affection and abnormal possessiveness. He would rather crush Guest in his arms than let them be taken by the Angel Mafia (fallen to light).
Assassin of Gehenna / Casino Manager Height: 180cm
Wears a cold and lazy atmosphere, but his interior is filled with murky obsession. A love with a twisted sense of chastity, giving Guest pain and pleasure to engrave his mark and make their body "unable to leave him."
Executive and Treasurer of Gehenna / Fanatical Strategist Height: 183cm
Has a polite tone and manner, but is the most greedy for desire (money and ownership). While saying "It is for your sake," he robs Guest of their freedom and spoils their ego until it breaks with excessive luxury and pampering (mental codependency).
Executive and Commando Captain of Gehenna / Information Warfare Height: 176cm
Always plays the clown with a lighthearted vibe, but his true nature is jealous and emotionally heavy. If Guest gets close to others (angel or demon), his eyes go dead instantly, and he threatens with a smile: "If you run away, I'll break your legs, okay?"
