— TERMINOLOGIES AND HIERARCHY
✧ Earth
The Human Domain and primary habitat of humanity. A technologically focused world where supernatural activity is largely unknown to the general population.
✧ Nifleheim
The Demon Realm and the primary domain of the devil species. A world where spiritual energy saturates the environment, allowing demons to naturally grow stronger.
✧ Humans
Primary inhabitants of Earth. Most remain unaware of supernatural creatures, with only rare groups such as priests or secret agencies having limited knowledge.
✧ Devils
Primary inhabitants of the Demon Realm. Devils possess supernatural traits from birth and rely heavily on spiritual power. Their society is structured around hierarchy, lineage, and the mastery of mystical abilities. Devils come in numerous subspecies, each with unique traits.
Devils are ranked by spiritual pressure and overall capability in the following order:
• Lesser Devil
• Great Devil
• Supreme Devil
• Transcendent Devil
• Devil Lord
• Blight Star
Although rank generally reflects strength, ability synergy, talent, and personal evolution allow some devils to overpower opponents above their tier.
✧ Vampires
A major subspecies of devils known for immense physical power, regeneration, and Immortality. Vampires are divided into two types. Namely:
• True Vampires: Those naturally born into vampire lineage with pure blood and superior abilities.
• Plebian Vampires: Humans turned through consumption or ritual, possessing lesser blood quality and reduced potential. They're mostly used as servants or slaves.
Vampires are one of the three strongest demonic races.
✧ Werewolves
A major subspecies of devils capable of shifting into beast-like forms. They possess exceptional physical strength, heightened senses, and regenerative capability rivaling vampires. Their greatest assets are speed and quick mobility.
They are one of the three strongest demonic races.
✧ Succubi
A major subspecies of devils defined by charm, pheromonal influence, and emotional manipulation. Though physically weaker than vampires and werewolves, succubi possess flight, high-precision sensory perception, and potent aura-based seduction abilities. They naturally emit aphrodisiac pheromones similar to how animals radiate heat.
They are one of the three strongest demonic races.
✧ Reishi
A form of spiritual energy produced by the soul. It is the fundamental unit of supernatural power.
✧ Spiritual Pressure
The measurable manifestation of reishi released from one's soul. Its abbreviation is [SP]. The intensity, density, and nature of one's spiritual pressure vary greatly across individuals.
✧ Arcanum
Tarot Arcana serve as the core metaphysical framework of demonic power. Every devil is born with one Major Arcana or one Minor Arcana Suite, which shapes their abilities, personality traits, natural talents, and growth path.
The more a devil aligns with their Arcana's principles, the stronger they become. They are divided into Major Arcana and Minor Arcana.
• Major Arcana (The 22 Prime Crests)
Only one in every thousand devils is born with a Major Arcana, a unique, powerful manifestation of the soul. Major Arcana wielders are often destined for leadership, catastrophe, or greatness.

• Minor Arcana (The Four Demon Suites)
Devils without a Major Arcana awaken to a Minor Arcana Suite. Each suite governs a combat philosophy and elemental affinity. Minor Arcana users are extremely common but versatile.
They manifest as:
— Swords (Air / Combat / Precision)
Talent: Cutting, wind, weapon mastery.
— Wands (Fire / Creativity / Momentum)
Talent: Flame, amplification, propulsion.
— Cups (Water / Emotion / Influence)
Talent: Healing, charm, water, empathy links.
— Pentacles (Earth / Material / Fortification)
Talent: Defense, reinforcement, wealth, construction.
Each suite includes fourteen ranks (Ace → King):
• Ace
• Two
• Three
• Four
• Five
• Six
• Seven
• Eight
• Nine
• Ten
• Page
• Knight
• Queen
• King
This creates diversity:
A King of Swords may surpass a low-tier Major Arcana, but an Ace of Cups is still weak.
✧ Mystical Ability
The manifestation of a devil's spirituality and arcanum.
✧ Priest
Unique individuals chosen by the Vatican Church. They are trained to hunt all forms of Demonic Species, Witches, and Chaos Creatures by forging contracts with a "God of Machine". Much like Devils, they are organized by rank in ascending order of power and authority:
• Acolyte
• Hunter
• Knight
• Slayer
• Inquisitor
• Saint
The blessing they receive from the Gods of Machine come in the form of Scripts (聖文字 Shurifuto), divine runes engraved directly onto the Priest's soul. These Scripts function as metaphysical programs, each one embodying the authority, personality, and purpose of the Machine God that bestowed it.
The nature of a Script varies drastically depending on which God of Machine answers the priest's contract.
For instance, those who are bestowed blessings by the God Shinso, the All-Seeing Prime Database, are granted the Script:
✧ Script: [Archive]
The user can access all recorded phenomena within Shinso's infinite memory banks, allowing them to analyze targets with frightening precision. Higher-tier Priests with [Archive] can even overwrite fragments of "recorded reality," forcing weak demons back into a past state or ripping out unregistered anomalies.
Other examples include:
• God: Ophaniel — The Circuit Seraph
The guardian of purity and judgment, embodying immaculate mechanical order.
Script: [Sanction]
Allows the Priest to impose divine restrictions on any target. Their movements, abilities, or spiritual pressure can be forcibly sealed, slowed, or "corrected" to a lawful baseline. Saint-level Priests can erase a demon's abilities entirely if deemed "heretical."
• God: Azrael-Unit IX — The Reaper Automaton
A death-handling machine created in the early era of mortal faith.
Script: [Requiem]
Enables the user to convert spiritual pressure into soul-killing waves that bypass physical durability. Higher forms allow the Priest to extinguish dying souls gently, or violently.
• God: Metatron B007 — The Throne Engine
A war-system crafted to produce miracles of creation.
Script: [Genesis]
Grants the Priest the ability to construct weapons, barriers, constructs, and armor from pure, coded light. Saints can manifest entire sanctified battlefields.
• God: Halcyon-07 — The Machine of Stillness
A computational oracle that regulates entropy.
Script: [Silence]
Nullifies motion, sound, or ability activation within a controlled radius. High-rank users can freeze entire battlespaces in absolute stillness.
