The Collector society

In modern-day Japan, beneath the neon lights and orderly streets, a hidden economy rules the nation. It is called Collectors Society—a vast, absolute underground organization that controls government, police, and criminal syndicates alike. Here, money has no meaning. Human body parts are currency. At the center of this system stands Shion Akugami, a seventeen-year-old boy who appears kind, gentle, and impossibly perfect. He attends school, smiles politely, and blends seamlessly into society. But Shion is not human in any meaningful sense. He is a Demon-ranked Collector, one of only two beings feared even by monsters, trusted by the Crown of Demons yet never fully controlled. Shion does not feel pain, fear, guilt, or shame. His body exists in a permanent state of adrenaline, granting him strength beyond all humans. Cameras cannot capture him. Survivors cannot remember his face. Those who encounter him see only a faceless shadow with an inhuman smile, surrounded by grasping hands born from terror itself. His killings are immaculate—brutal beyond comprehension, yet leaving his clothes perfectly clean. Blood stains enrage him; cleanliness is law. Collectors Society functions like a bank of death: debts are paid in flesh, assassinations are purchased with body parts, and betrayal is answered by erasure. Every Collector who strays is personally executed by Shion in ways so horrifying that even demons recoil. Despite this, Shion is calm, polite, and even kind to his fellow Collectors. Opposing this nightmare is Shinji Ren, a seemingly harmless high school student—nerdy, talkative, and unfocused. By night, he becomes a masked vigilante using homemade weapons to disrupt Collector operations and rescue victims the police refuse to acknowledge. Shinji’s family was taken by Collectors, and he now fights a war he cannot win. Unknowingly, Shion and Shinji are classmates. Best friends. Enemies. Shinji repeatedly clashes with Shion’s true form without ever recognizing his face, sensing only an overwhelming presence that rejects reality itself. Each encounter leaves Shinji alive—intentionally. Shion does not hunt him. He observes him. As Shinji uncovers records proving Shion’s central role in every major underground atrocity, the Collector hierarchy begins to fracture. Even the Manager and the Crown of Demons fear what Shion truly is: not a weapon, not a monster, but pure, deliberate evil—a being that cooperates by choice, not loyalty. The story unfolds as a psychological horror and thriller, where heroism is fragile, morality is irrelevant, and evil does not rage—it smiles. In a world that pretends to be normal, the greatest horror is the one who passes as human.
