✐ W𝚘𝚛𝚕𝚍 O𝚟𝚎𝚛𝚟𝚒𝚎𝚠 𓍝

✐ Core Source of Power: F.E.A.R 𓍝
Concept Embodiment: Every Devil is born in Hell and embodies a specific abstract or physical concept (e.g., the Darkness Devil, the Gun Devil, or a hypothetical Coffee Devil).
The Scaling Rule:The more a concept is feared by humanity (or other living things), the stronger the corresponding Devil becomes. For example, the Gun Devil is massively powerful because global gun violence and terror spike its fear metrics. When a Devil dies in the human world, it reincarnates in Hell, and vice versa, losing memories of its previous life. [1]

✐ The Hierarchy of Entities: 𓍝
Power manifests through different types of beings and physiological states: [1]
Primal Fears:At the absolute peak of the natural Devil hierarchy are the Primal Devils (representing universal fears like the dark, falling, or death). They have never experienced death in Hell and possess incomprehensible, god-like might that far exceeds normal Earth-bound devils.
Special/Horsemen Devils:High-ranking entities like Control, the War Devil, or Famine represent fundamental, large-scale societal or psychological concepts. They wield immense authority and unique control mechanics.
Standard Devils:Pure supernatural creatures native to Hell or Earth whose power correlates strictly to human perception and fear of their names.
Fiends:Devils that have taken over a dead human corpse. They retain the Devil's personality (mostly) and unique physical traits (like horns) but possess weaker versions of their original abilities and are semi-mortal.
Hybrids [Weapon Humans]:Extremely rare individuals whose heart has been replaced by a Devil (typically a Weapon Devil like Chainsaw, Bomb, or Katana). They retain complete human consciousness, transform into a human-devil hybrid by activating a physical trigger (eg, pulling a chest cord or pin), and are functionally immortal as long as they consume blood. [1]

✐ Human Contracts and Sacrifices: 𓍝
The Cost of Deals:Regular humans possess no inherent magic. To fight or use powers, they must form binding contracts with Devils, trading something of personal value-such as lifespan, body parts, blood, or sensory organs-in exchange for borrowing the Devil's abilities. [1]

✐ The PSDH [Public Safety Devil Hunters]: 𓍝
The Public Safety Devil Hunters are a specialized, government-sanctioned organization in Japan tasked with protecting civilians from Devil attacks. Operating under the jurisdiction of the Ministry of Internal Affairs, they function like a militarized police force or national security agency, but exclusively for supernatural threats.
