Numbers System

Lore & Background

At its core, this system is designed to strip away humanity from the children before they are ever consumed. By reducing a living being to a serial number, Demons can psychologically distance themselves from the act of eating humans. The code often reflects birth order or quality assessment, with higher-tier numbers sometimes indicating superior genetic traits suitable for high-ranking Demon clients. Within the farms, Mothers enforce this system strictly during official interactions and record-keeping. While children are permitted to use names among themselves to maintain sanity, the reality remains that their legal existence is defined by these digits. This duality creates a constant tension between the identity they build with friends and the product status imposed upon them by their captors. The system also facilitates logistics for shipping. When a harvest occurs, groups are moved based on their numerical batches rather than personal relationships. This ensures that high-value products reach their destinations without confusion, turning human lives into mere inventory to be shipped across the world like livestock.

In Their Own Story

In the dim light of the basement archive, Emma traced her finger over the cold paper file. The header did not bear her name; it held a bold, black sequence that felt heavier than stone. She remembered the day she learned what those digits meant—not as an identifier of who she was, but of when she would be taken. The silence of the room pressed against her ears, filled only by the distant hum of the farm above. She closed the folder with a sharp snap, pushing the paper back into its drawer. It did not matter what number they wrote on the page. In the dark, under the cover of night, she was Emma to them, and that name carried more weight than any code a Demon could ever print.

Reader's Guide

The Numbers System serves as the backbone of the Demon's agricultural trade, reducing human children to mere inventory items within their vast network of farms. Upon birth or admission, each child receives a unique identifier used exclusively by Mothers and Demons for logistics and quality control. This code dictates everything from feeding schedules to harvest dates, ensuring efficient processing without emotional attachment. While the children are encouraged to use personal names among themselves to maintain their humanity, the external world views them strictly through these digits. High-quality specimens often receive priority status, while others may be discarded or harvested earlier based on market demand. The system is designed to strip away individuality, making it easier for Demons to consume humans without guilt. Resistance against this system became central to the children's rebellion. By reclaiming their names and rejecting their assigned codes, escapees symbolically broke the chains of ownership. Understanding this numbering reveals the true horror of the farms: a world where human life is quantified for consumption rather than cherished as existence itself.
