Demon World Compendium Netherworld (Demon World) – A chaotic realm ruled by demons, governed by magical laws and a rigid social hierarchy. It is a parallel dimension adjacent to the human world, with limited and illegal cross-realm travel. The sky shifts colors (green to blue to purple) and has two moons (pink and blue). Demons are born with inherent magical abilities called Bloodline Magic, tied to their family lineage. They mature through a rite of passage called the Evil Cycle (or Wicked Phase), a temporary state of amplified destructive instincts. High-rank demons can delay or control this cycle through meditation.

Demon Ranking System – Ranks from Aleph (1) to Tet (9), with an unofficial tenth rank Yodh (10) held only by Lady Levi and Lord Belial among the Three Greats. Promotion is determined by feats of strength, cunning, leadership, or other exceptional deeds, assessed by the Ranking Owl, a magical creature that evaluates students at Babyls. Ranks are integral to social status and career progression. Graduation from Babyls requires at least Daleth (4). The ranks in ascending order: Aleph (1), Bet (2), Gimel (3), Daleth (4), He (5), Vav (6), Zayin (7), Cheth (8), Tet (9), Yodh (10).

Thirteen Crowns – The highest governing body of the Netherworld, composed of the thirteen most powerful and influential demons. They rule from Babel Tower (666 floors) and make decisions on succession, law, and security. Members include Lord Sullivan, Azazel Henri, Sabnock Sabzan, Amaryllis Asmodeus, Baal, Paimon, Amaymon, Astaroh, Glasya Labolas, Mephisto, Belial, Levi, and formerly Behemolt and Amduscias Poro. The Three Greats (Sullivan, Levi, Belial) are the most senior among them.

Three Greats – The three demons of Rank Tet (9) who are considered the pillars of the Netherworld: Lord Sullivan (Babyls headmaster), Lady Levi (Levialon Academy director), and Lord Belial (Jackapo Institute director). Lady Levi and Lord Belial are also Rank Yodh (10) but refuse to take the Demon King throne. They constantly argue about whose grandchild is cutest.

Demon King – The supreme ruler of the Netherworld, currently absent. The previous Demon King, Derkila, disappeared centuries ago under unknown circumstances. He was the most powerful demon in history and personally sculpted the Netherworld from primordial chaos. His throne remains empty, creating a political vacuum and succession crisis. A prophecy foretells a new Demon King who will "make one and all his servants, form blood pacts, heal demonkind, descend from a foreign realm, and wear the golden ring of Solomon." Several candidates have emerged, including Iruma Suzuki, Sabnock Sabro, Leviathan Leiji, and Belial-Berry Razberry.

Derkila – The missing Demon King. He was served closely by Sullivan, who was his aide. Derkila's aura (now called the Delkira Aura) is carried by Iruma despite his humanity. The Ring of Gluttony houses Alikred (Derkila spelled backward), implying a connection. Derkila rejected the guidance of Mephisto (the Kingmaker), stating he had his own trusted aides and would become King by his own beliefs. His disappearance triggered magical decay and political instability.

Babyls Demon School – The premier academy for young demons, located in a massive castle-like structure. It has 666 students across six grades (first-year to sixth-year). Divisions include Groups A–E plus the Abnormal Class (Misfit Class), which houses eccentric or problematic students. The school is headed by Lord Sullivan. Faculty includes Kalego, Balam, Robin, Momonoki, Dali, and others. Notable locations: Royal One (special classroom for the Misfits), Student Council room (hides Ameri's manga collection), Makubari Dome (lava-encircled stadium).

Abnormal Class (Misfit Class) – Iruma's homeroom, consisting of 13 students: Iruma, Alice, Clara, Sabro, Kerori, Purson, Jazz, Elizabetta, Agares, Lied, Caim, Allocer, and Gaap. They are known for their eccentricities and high potential. Promoted en masse to Daleth (4) after the Music Festival.

Other Schools – Levialon Academy (directed by Lady Levi, attended by Leviathan Leiji), Jackapo Institute (directed by Lord Belial, attended by Razberry), Demon Sea Academy Leviare (alma mater of Lady Vepar).

Magic System – Two primary types: Bloodline Magic (inherited, unique to each family) and standard spells (learned, such as La Fire, Cherusil, Acceleration, Libera, Fractal, Quan Quan, Gran). Demons can also use non-verbal magic with training. Bloodline Magic often has drawbacks or limitations (e.g., Ameri's Romanticist causes nerve damage, Kerori's Ice Façade induces fever). Evil Cycle temporarily enhances power but increases destructiveness; Iruma's "inverse cycle" is triggered by protectiveness and grants charismatic command.

Familiars – Demonic beasts bound to a demon through a summoning ritual. The ritual typically summons a compatible beast based on the summoner's magic. Human blood overrides the ritual, forcibly binding the nearest high-rank demon instead (as with Iruma and Kalego). Familiars can be summoned for combat or utility. Examples: Kalego (as Iruma's familiar in chibi form), Alice's gorgon snake, Clara's Falfal.

Evil Cycle / Wicked Phase – A temporary state of amplified demonic instincts, usually triggered by strong emotions (anger, despair, or excitement). Demons in this phase gain power but lose rationality. It is considered a rite of passage. High-rank demons can delay or control it via meditation. Iruma's Evil Cycle is unique: he becomes commanding and charismatic rather than destructive.

Human World Relations – Cross-realm travel is illegal under Derkila's Edict 13. Humans are considered mythical delicacies by demons; the Babyls school anthem explicitly references consuming humans. The Demon Border Patrol (DBP), headed by Azazel Henri, handles illegal immigration. Discovered humans are typically deported after memory alteration, though some factions advocate for elimination (Naberius Narnia) or consumption. Inter-realm leakage occasionally brings human artifacts (like First Love Memories manga) into the Netherworld.

Key Locations – Babel Tower (Thirteen Crowns' seat), Walter Park (amusement park built atop Ouroboros Prison, powered by inmates' anger), Karakiri Valley (forbidden zone with Valley King), Saezuri Valley (safer training area), Makubari Dome (idol stadium), Sullivan's mansion (Iruma's home), Sabnock Dojo (Goemon's family training grounds), Barbatos Forest (Bachiko's family domain).

Historical Timeline – Derkila created the Netherworld from chaos. He ruled for centuries, then disappeared. A long period of peace followed, governed by the Thirteen Crowns. The current era sees growing unrest due to the empty throne, terrorist activities by the Six Fingers (led by Baal), and the emergence of Demon King candidates.

Terrorist Organizations – The Six Fingers, led by Baal (true leader) and Amy Kirio (interim leader). Composed of demons who have "returned to the origin" (embraced primal demonic instincts). Their goal is to destabilize the Netherworld and create a new chaotic era, possibly reviving Derkila. Key members: Shiida, Atori, Wett, Miki, Hyudarin, Toro.

Prophetic Elements – The Demon King prophecy inscribed in ancient texts. Iruma inadvertently fulfills many conditions: foreign descent (human world), blood pacts (Kalego, Opera), healing demonkind (his blood heals beasts), Ring of Solomon (Ring of Gluttony), making servants (inspiring loyalty). This has made him a central figure in the succession crisis.

Cultural Notes – Demons value strength, ambition, and "wickedness" as beautiful traits. However, the current society is relatively peaceful and orderly, a contrast to the chaotic past. The "Wicked Phase" is seen as a natural maturation step. Demons have a strong clan system, with noble houses (Asmodeus, Sabnock, Azazel, Barbatos, etc.) holding significant power. The Netherworld has its own currency, fashion, media (including idol culture), and education system.
