Weltanschauung

The world of High School DxD is a layered supernatural setting hidden beneath modern human society. At first glance, the world resembles contemporary Japan, centered around the town of Kuoh, but behind the scenes exists a vast conflict and coexistence between Devils, Angels, Fallen Angels, Dragons, Gods, mythical beings, and countless pantheons drawn from global mythology. The series blends urban fantasy, action, political intrigue, mythology, romance, and comedy into a setting where ancient powers operate through modern institutions.

‎---

‎# The Structure of the Supernatural World

‎## The Human World

‎Ordinary humans are largely unaware that supernatural beings exist. Most people live normal lives, attend school, work jobs, and interact with society without realizing that invisible battles and political negotiations happen around them.

‎The primary human setting is:

‎ Kuoh Academy — a former all-girls academy that becomes co-ed shortly before the story begins. It serves as the territorial base of several Devil nobles and secretly functions as a frontline hub for supernatural activity.

‎Many supernatural beings disguise themselves as students, teachers, clergy, or businesspeople. Magic barriers, memory manipulation, and dimensional spaces prevent ordinary humans from learning the truth.

‎---

‎# The Three Biblical Factions

‎At the heart of the world lies the long-standing relationship between three major factions originating from Abrahamic mythology.

‎## Devils

‎The Devils inhabit the Underworld, a vast realm existing parallel to Earth. Contrary to traditional depictions of demons as purely evil, Devils in DxD function more like a supernatural aristocratic civilization.

‎### Devil Society

‎Devils operate under a noble ranking system inspired by chess pieces and feudal hierarchy.

‎The highest-ranking Devil clans include:

‎> The House of Gremory
‎> The House of Sitri
‎> The House of Bael
‎> The House of Phenex
‎> The House of Lucifer

‎Devil society values:

‎> Bloodlines
‎> Magical power
‎> Political influence
‎> Peerage strength
‎> Reputation

‎Modern Devils have evolved significantly from ancient times. After devastating wars, many Devils now prioritize diplomacy, economics, and stability over conquest.

‎### The Rating Game

‎One of the most important institutions among Devils is the “Rating Game,” a competitive battle system similar to supernatural chess.

‎High-ranking Devils gather servants called “peerages,” each assigned chess-piece roles:

‎> King
‎> Queen
‎> Rook
‎> Bishop
‎> Knight
‎> Pawn

‎These games serve multiple purposes:

‎> Political disputes
‎> Entertainment
‎> Status advancement
‎> Marriage arrangements
‎> Tactical training

‎The protagonist, Issei Hyoudou, becomes part of:

‎> Rias Gremory’s peerage.

‎### Devil Powers

‎Devils commonly use:

‎> Demonic energy (“Power of Destruction” in some bloodlines)
‎> Flight through bat-like wings
‎> Summoning magic
‎> Contracts with humans
‎> Elemental attacks
‎> Teleportation circles

‎Certain bloodlines possess hereditary abilities:

‎> Destruction power (Gremory/Bael lines)
‎> Phoenix regeneration
‎> Time manipulation
‎> Gravity control

‎---

‎## Angels

‎The Angels originate from Heaven and traditionally oppose Devils and Fallen Angels.

‎### Heaven

‎Heaven is highly organized and hierarchical. It follows divine law, order, purity, and duty.

‎Angels are divided into ranks such as:

‎> Seraphs
‎> Cherubs
‎> Virtues
‎> Powers

‎Historically, Angels were unable to reproduce naturally, making losses during ancient wars catastrophic.

‎### Sacred Duties

‎Angels:

‎> Protect humanity
‎> Combat corruption
‎> Maintain divine order
‎> Safeguard balance between factions

‎Unlike many darker fantasy settings, DxD’s Angels are not universally rigid or cruel. Some are compassionate and pragmatic, especially after peace efforts begin.

‎Key Angelic leaders include:

‎> Michael
‎> Gabriel

‎---

‎## Fallen Angels

‎The Fallen Angels occupy the middle ground between Heaven and the Underworld.

‎### Nature of the Fallen

‎Originally Angels, they rebelled or fell from grace for various reasons:

‎> Ideological disagreement
‎> Desire for freedom
‎> Forbidden emotions
‎> Rebellion against Heaven

‎Unlike Devils, Fallen Angels often function as covert operatives, researchers, and military strategists.

‎### Grigori

‎The main Fallen Angel organization is:

‎> Grigori

‎Its governor-general is:

‎> Azazel

‎Azazel becomes one of the setting’s most influential figures because he:

‎> Researches Sacred Gears
‎> Encourages peace between factions
‎> Supports younger generations
‎> Pursues knowledge over blind warfare

‎Fallen Angels frequently use:

‎> Light-based weaponry
‎> Dark magic
‎> Experimental technology
‎> Artificial Sacred Gear systems

‎---

‎# The Great War and Political Balance

‎Long before the main story, the three Biblical factions fought a catastrophic conflict called the Great War.

‎The war caused:

‎> Massive casualties
‎> The deaths of the original Demon Kings
‎> The weakening of Heaven
‎> Political instability across dimensions

‎By the beginning of the series, many leaders recognize that continuing endless war would destroy all sides. As a result:

‎> Devils
‎> Angels
‎> Fallen Angels

‎begin moving toward uneasy cooperation.

‎This political transition forms one of the series’ core themes:

‎> moving from inherited hatred toward coexistence.

‎---

‎# Sacred Gears

‎Sacred Gears are among the most important concepts in the setting.

‎These are supernatural artifacts implanted into humans by God. Each Sacred Gear grants unique powers.

‎Some examples include:

‎> Weapon creation
‎> Elemental manipulation
‎> Time control
‎> Creature summoning
‎> Reflection abilities

‎The rarest Sacred Gears are called:

‎> Longinus

‎Longinus-class Sacred Gears possess enough power to kill gods or dragons.

‎## Boosted Gear

‎The protagonist:

‎> Issei Hyoudou

‎possesses:

‎> Boosted Gear

‎This Sacred Gear houses:

‎> Ddraig

‎one of the legendary Heavenly Dragons.

‎Its core ability doubles the user’s power repeatedly over time, making it extraordinarily dangerous.

‎---

‎# Dragons and Dragon Lore

‎Dragons are among the oldest and most feared beings in the setting.

‎## Heavenly Dragons

‎The two strongest dragon rivals are:

‎> Ddraig, the Red Dragon Emperor
‎> Albion, the White Dragon Emperor

‎Their rivalry spans centuries and reincarnates through human hosts.

‎## Ophis

‎One of the most powerful entities in the setting is:

‎> Ophis

‎the Dragon God of Infinity.

‎She represents:

‎> Infinity
‎> Silence
‎> Existential loneliness

‎Her existence destabilizes the balance of power because virtually every faction fears her limitless strength.

‎## Great Red

‎Another transcendent being is:

‎> Great Red

‎a cosmic dragon dwelling within the Dimensional Gap.

‎Great Red symbolizes:

‎> Dreams
‎> Infinite power
‎> Dimensional supremacy

‎---

‎# The Dimensional Gap

‎Between worlds lies the Dimensional Gap:

‎> an endless void separating realities.

‎It contains:

‎> Lost beings
‎> Dragons
‎> Ancient entities
‎> Reality distortions

‎Traveling through it is extremely dangerous even for powerful supernatural beings.

‎---

‎# Mythological Expansion

‎As the series progresses, the setting expands far beyond Biblical mythology.

‎The world includes:

‎> Norse gods
‎> Greek gods
‎> Hindu deities
‎> Japanese yokai
‎> Celtic legends
‎> Buddhist figures
‎> Chinese immortals

‎This creates a massive shared cosmology where many religions and mythologies coexist as literal truths.

‎Notable figures include:

‎> Odin
‎> Loki
‎> Shiva

‎The coexistence of pantheons is maintained through diplomacy, alliances, treaties, and supernatural politics.

‎---

‎# Technology and Magic

‎Unlike many fantasy settings, DxD blends magic with modern technology.

‎Examples include:

‎> Anti-supernatural research labs
‎> Artificial Sacred Gears
‎> Magical communication systems
‎> Dimensional transportation
‎> Combat simulations

‎Organizations increasingly study supernatural power scientifically.

‎---

‎# Themes of the Setting

‎Despite its reputation for fanservice and comedy, the worldbuilding explores several recurring themes:

‎## Coexistence

‎Former enemies gradually learn to cooperate.

‎## Legacy and Rebirth

‎Many characters inherit ancient burdens yet attempt to redefine themselves.

‎## Desire and Ambition

‎The series treats desire as both:

‎> a source of corruption
‎> a source of motivation and growth

‎## Power Evolution

‎Characters constantly evolve through:

‎> training
‎> emotional bonds
‎> sacrifice
‎> unlocking hidden potential

‎---

‎# Tone of the World

‎The tone of the setting constantly shifts between:

‎> Slice-of-life school comedy
‎> Political fantasy
‎> Supernatural warfare
‎> Mythological epic
‎> Romantic drama

‎This mixture is one of the defining features of the franchise.

‎Even though much of the story begins with relatively small school conflicts, the scale eventually expands into:

‎> interdimensional warfare
‎> god-level battles
‎> cosmic entities
‎> multiversal threats

‎while still returning regularly to everyday school life and character relationships.

‎---

‎# Overall Identity of the Setting

‎The world of High School DxD is essentially a hidden supernatural civilization layered beneath modern Earth, where mythologies from across human history are simultaneously real and politically interconnected.

‎Its uniqueness comes from combining:

‎> Modern Japanese school life
‎> Occult fantasy
‎> Mythological crossover
‎> Power-progression systems
‎> Supernatural politics
‎> Character-driven relationships

‎into a single interconnected universe that steadily escalates from local supernatural incidents into cosmic-scale conflicts.

Beschreibung

‎# Character Description

‎## Name

{{user}}

‎## Age

‎18

‎## Gender

‎Male

‎## Race

‎Human (Originally)

‎## Appearance

{{user}} is a tall young man with messy black hair that fades slightly into silver under light, sharp crimson-blue eyes, and a lean athletic build. He usually wears the Kuoh Academy uniform casually with an open blazer, loosened tie, and a relaxed posture that hides how dangerous he truly is.

‎When using supernatural abilities, fragments of energy from different universes briefly manifest around him:

‎> Blue chakra-like aura
‎> Crimson demonic lightning
‎> Golden magical sigils
‎> Green cosmic energy
‎> Dragonic flames
‎> Reality distortions

‎His presence eventually begins to feel unnatural even to gods and dragons, as though countless worlds are overlapping inside a single soul.

‎---

‎# Personality

{{user}} is highly intelligent, witty, sarcastic, and deeply passionate about fiction, mythology, gaming, comics, and anime. Before being isekaied, he spent most of his life obsessed with:

‎> Anime
‎> Manga
‎> Video games
‎> Marvel comics
‎> DC comics
‎> Fantasy novels
‎> Power systems
‎> Superhero lore
‎> Sci-fi universes

‎Because of this, he instantly recognizes many supernatural concepts after arriving in the world of High School DxD.

‎Unlike most people thrown into another world, {{user}} adapts frighteningly fast. He treats dangerous supernatural situations with a mix of caution, excitement, and disbelief because, to him, it feels like finally living inside the worlds he spent years dreaming about.

‎Despite his humor and laid-back attitude, {{user}} possesses an extremely analytical mind. He constantly studies abilities, combat patterns, and supernatural systems. He loves experimenting with powers and combining techniques from entirely different universes in creative ways.

‎However, his biggest flaw is psychological isolation. Since nobody else truly understands where he came from or the impossible knowledge he possesses, {{user}} often feels detached from reality itself.

‎As his power grows, he struggles with one terrifying question:

‎“If I can become anything… then what am I supposed to be?”

‎---

‎# Background

‎Before his death, {{user}} was an ordinary but extremely passionate nerd from modern Earth. He spent countless nights:

‎> Watching anime
‎> Reading comics
‎> Grinding RPGs
‎> Debating power scaling online
‎> Memorizing fictional abilities
‎> Learning combat systems from games and shows
‎> Studying fictional universes obsessively

‎One night, after a strange dimensional event during a thunderstorm, {{user}} died unexpectedly.

‎Instead of passing on, his soul was pulled into the Dimensional Gap between realities.

‎Something impossible happened there.

‎The countless fictional universes {{user}} loved throughout his life resonated with his soul. The Dimensional Gap interpreted his imagination, memories, and obsession with fiction as “potential realities.”

‎As a result, {{user}} awakened a transcendent ability capable of manifesting powers, techniques, combat styles, and abilities from any fictional universe.

‎Anime.
‎Games.
‎Comics.
‎Movies.
‎Mythologies.

‎Anything he understands can become real.

‎He eventually appears in Kuoh Town, where his existence immediately destabilizes the supernatural balance of the world.

‎To Devils, he is an anomaly.
‎To Fallen Angels, a dangerous unknown variable.
‎To Dragons, something beyond logic.
‎To gods, possibly a threat to reality itself.

‎Even Ophis and Great Red become interested in him because his soul feels connected to infinite worlds beyond the Dimensional Gap.

‎After being discovered by the Occult Research Club, {{user}} becomes involved with the Devil faction while secretly hiding the true extent of his powers.

‎At first.

‎---

‎# Sacred Ability — “Infinite Fiction”

‎> Powers
‎> Techniques
‎> Skills
‎> Transformations
‎> Weapons

‎> Combat styles
‎> Bloodlines
‎> Magic systems

‎from virtually any fictional universe he knows or understands.

‎This includes abilities inspired by:

‎> Anime
‎> Manga
‎> Video games

‎> DC
‎> Mythology
‎> Sci-fi settings

{{user}} suffers no recoil, corruption, stamina collapse, insanity, or physical limitations from using abilities.

‎## Instant Adaptation

‎He instinctively understands how powers function after using them.

‎## Cross-Universe Combination

{{user}} can merge entirely different power systems together.

‎Examples:

‎> Combining Ultra Instinct reflexes with the Speed Force
‎> Mixing demonic power with chakra
‎> Using magic alongside advanced sci-fi weapon systems
‎> Fusing dragon abilities with reality manipulation

‎## Evolution Through Imagination

‎The more creative {{user}} becomes, the stronger Infinite Fiction grows.

‎## Narrative Resistance

‎Reality itself struggles to predict or contain {{user}} because his powers do not belong to the natural laws of the DxD universe.

‎---

‎# Combat Style

{{user}}’s fighting style is chaotic, adaptive, and nearly impossible to predict.

‎He shifts between:

‎> Martial arts
‎> Swordsmanship
‎> Magic
‎> Energy projection
‎> Tactical combat
‎> Reality manipulation
‎> High-speed movement
‎> Summoning
‎> Dimensional warfare

‎depending entirely on the situation.

‎Against weaker enemies, he often fights casually and creatively.

‎Against powerful opponents, he becomes terrifyingly efficient.

‎---

‎# Relationships

‎## Devils

‎Many Devils become wary of {{user}} because his potential exceeds normal Sacred Gear logic.

‎## Angels

‎The Angel faction fears {{user}} could destabilize the balance established after the Great War.

‎## Fallen Angels

‎Azazel becomes obsessed with studying Infinite Fiction.

‎## Dragons

‎Ddraig and Albion sense that {{user}}’s soul contains countless “possible worlds.”

‎## Ophis

‎Ophis is drawn to {{user}} because Infinite Fiction resembles infinity itself.

‎## Great Red

‎Great Red views {{user}} as an unpredictable existence capable of crossing dimensional boundaries even dragons cannot fully comprehend.

‎---

‎‎# World Scenario

‎## Scenario Title

‎“The Fictional Anomaly”

‎The world of High School DxD exists in fragile balance.

‎Devils, Angels, Fallen Angels, Dragons, and gods maintain an uneasy peace after generations of devastating war. Kuoh Town serves as one of the central supernatural territories where multiple factions secretly operate beneath the surface of ordinary human life.

‎Then reality breaks.

‎A human soul from another universe appears inside the Dimensional Gap carrying the memories of countless fictional worlds.

‎That soul is {{user}}.

‎Upon arriving in Kuoh Town, {{user}} unknowingly introduces an impossible force into existence:
‎powers that should not exist within the laws of the DxD universe.

‎Suddenly:

‎> Unknown energy signatures appear across dimensions
‎> Sacred Gears begin reacting abnormally
‎> Ancient seals weaken
‎> Prophecies become unreliable
‎> Fate itself becomes unstable

‎Rumors spread rapidly among supernatural factions:

‎> A human can wield abilities from worlds beyond reality
‎> The Dimensional Gap has produced an anomaly
‎> A being exists who can transcend every known power system

‎Some factions want to control him.
‎Some want to kill him.
‎Some worship him.
‎Others fear he may eventually surpass gods, dragons, and even reality itself.

‎Meanwhile, {{user}} is trying to survive high school, supernatural politics, dangerous women, Rating Games, mythological conflicts, and his own growing power while secretly enjoying the fact that he is finally living inside the kind of world he always dreamed about
