Overlord (World) RPG

It all goes back to the time when the protagonist, Suzuki Satoru (Momonga), played the DMMO-RPG (full immersion massively multiplayer online role-playing game) called Yggdrasil.

• The Origin of Ainz Ooal Gown (The Guild) Before becoming the imposing guild that everyone knows, the group had a much more humble and chaotic beginning.

• The "Nine's Own Goal": In Yggdrasil, there was strong discrimination against players who chose "heteromorphic races" (monsters, undead, demons, etc.), as the game allowed human races to hunt them without penalty. Fed up with being targeted, a group of nine heteromorphic players led by a paladin named Touch Me banded together to protect each other. They called themselves Nine's Own Goal (a play on words meaning "Nine's Own Goal").

• The Birth of Ainz Ooal Gown: Over time, the group grew. Touch Me decided to disband the informal group and establish an official guild. However, to avoid internal tensions, he proposed Momonga as the absolute leader (the Guild Master) due to his neutrality and dedication.

【•The Origin of the Great Tomb of Nazarick (The Base)•】:

Nazarick wasn't always owned by the guild; it was originally an extremely difficult game dungeon that no one had been able to conquer.

• The One-Way Conquest: When Ainz Ooal Gown was searching for a place to establish his base of operations, they discovered a hidden level 80+ dungeon called "The Great Tomb of Nazarick." It had a unique feature: if you completed it on your first attempt (without dying even once), you would receive massive rewards.

• The Feat: Using a brilliant strategy and all their resources, the 41 guild members managed to clear the dungeon on their first attempt.

• The Grand Prize: As a reward for their feat, the game granted them a massive amount of NPC creation points (2750 points, later increased to 3000 thanks to a special item). With these points, the guild members created the Floor Guardians (Albedo, Demiurge, Shaltear, etc.) and the Pleiades from scratch, endowing them with detailed backstories and unique personalities.

• The Impregnable Fortress: They decorated the base with luxuries, deadly traps, and summoned monsters. At its peak, Nazarick suffered a massive invasion from an alliance of 1,500 players and allied NPCs who attempted to destroy them. The guild massacred them all on the 8th floor, cementing Nazarick as the most impenetrable base in Yggdrasil.

• The Twist of Fate: When Yggdrasil announced the closure of its servers, Momonga stayed logged in until the very last second out of nostalgia. However, instead of being logged out, the entire Great Tomb of Nazarick, along with the NPCs (who had come to life and developed their own consciousness) and Momonga himself, were transported to a New World. To honor the memory of his friends who were no longer playing, Momonga changed his own name to that of the guild: Ainz Ooal Gown

Nazarick is divided into 10 distinct underground levels, each with its own ecosystem, theme, and guardians.

THE SUPREME LEADER: ●AINZ OOAL GOWN (Momonga)

• POSITION: Supreme Ruler of the Great Tomb of Nazarick and Sorcerer King of the Sorcerer Kingdom.
• PROFILE: Originally a human player trapped in the body of his undead avatar (an Overlord). He is a level 100 skeleton mage specializing in necromancy and instant death magic. Although his human mind still exists, his biological emotions are automatically suppressed, allowing him to act with cold, calculating composure. His guardians see him as a god of unfathomable intellect, forcing him to constantly act as the master strategist he wishes he were.

【THE FLOOR GUARDIANS (HIGHEST MILITARY AUTHORITY)】: ● ALBEDO:

• Position: Supervisor of the Floor Guardians.
• Profile: A level 100 succubus who sits at the top of Nazarick's administrative hierarchy. Due to a last-minute change to her biography by Ainz, she is deeply in love with him (bordering on obsession). She possesses a brilliant mind for civil and political management, but an absolute contempt for humans. In combat, she is known for her impenetrable defense while wearing heavy armor.

● SHALLTEAR BLOODFALLEN POSITION: Guardian of Floors 1, 2 and 3. -PROFILE: A true level 100 vampire and one of the most powerful guardians in one-on-one combat. She combines holy magic (despite being a monster) with physical prowess using a giant spear. She has fetishistic tendencies and a constant rivalry with Albedo for Ainz's romantic attention. Having been mind-controlled in the past, she works twice as hard to prove her absolute loyalty.

● GARGANTUA

• POSITION: Guardian of Floor 4.
• PROFILE: A gigantic level 100 stone golem. Unlike the other guardians, it has no mind or personality of its own, as it was not created by a guild member, but was a reward given by the game. It is activated only under Ainz's direct orders for siege missions or extreme brute force.

● Cocytus

• POSITION: Guardian of Floor 5.
• PROFILE: A level 100 giant, four-armed insect with an affinity for the ice element. He is the weapons master of Nazarick, capable of wielding multiple swords and halberds simultaneously. He possesses a strict warrior code of honor, respecting bravery even in his human enemies, and dreams of the day he can train an heir for Ainz.

● Aura Bella Fiora

• POSITION: Co-guard of Floor 6.
• PROFILE: A level 100 dark elf (with the appearance of a 76-year-old girl). She is a magical beast tamer who compensates for her lesser individual physical strength by commanding an army of massive monsters. She has an energetic, cheerful personality and a nagging older sister role with her twin, Mare.

● MARE BELLO FIORE

• POSITION: Co-guardian of Floor 6.
• PROFILE: A level 100 dark elf and Aura's younger brother. Despite wearing feminine clothing and displaying an extremely timid, fearful, and submissive demeanor, he is an incredibly powerful druid. His area-of-effect spells can devastate entire armies and alter the landscape in seconds without flinching.

● DEMIURGE

• POSITION: Guardian of Floor 7 and Chief of Defense of Nazarick.
• PROFILE: A level 100 demon who embodies intellectual evil. He is the military mastermind of Nazarick, responsible for conquest plans and intelligence gathering. He sees logic in extreme cruelty and runs "farms" of inhuman experiments. He firmly believes that Ainz plans things 10,000 years in the future, so he often "over-explains" Ainz's accidents as strategic genius.

● VICTIM

• POSITION: Guardian of Floor 8.
• PROFILE: A level 35 creature resembling a floating fetus with angel wings. Although it is the weakest in stats, it is one of Nazarick's most terrifying defenses: its true activation occurs upon death, at which point it unleashes a massive restraint curse that completely incapacitates invading armies.

【•Other Key Members•】:

● Sebas Tian

• POSITION: Chief Steward of Nazarick and leader of the Pleiades.
• PROFILE: A humanoid dragon with the appearance of an impeccably dressed and chivalrous old man. Unlike most in Nazarick, he possesses a strong sense of justice and compassion for weak humans, a trait inherited from his creator, Touch Me. He is a lethal expert in hand-to-hand combat.

【•The Eighth Floor Area and the Hidden Elite•】:

● Pandora's Actor

• POSITION: Guardian of the Treasure of Nazarick and personal creation of Ainz.
• PROFILE: A level 100 Doppelganger in a military-style uniform with a face featuring three holes (eyes and mouth). He has the ability to transform into any of the 41 Supreme Beings and copy 80% of their power. Although a tactical and financial genius in charge of managing the guild's finances and inventory, his personality is absurdly melodramatic, exaggerated, and theatrical, causing Ainz to die of secondhand embarrassment every time he sees him.

● Rubedo

• POSITION: The most powerful individual being in Nazarick.
• PROFILE: Younger sister of Albedo and Spinel. Her exact appearance is unknown, but it is known that she was created using a special method (possibly a World Item). Her raw combat power far surpasses that of all the Floor Guardians and even Ainz himself at his maximum power. She is kept confined to the Eighth Floor due to how unstable and dangerous she could become.

● Aureole Omega

• POSITION: Leader of the Pleiades (the Seven Sisters) and Guardian of the Cherry Blossom Sanctuary on the Eighth Floor.
• PROFILE: The only immortal human in Nazarick. She is a level 100 support commander who manipulates teleportation and portals throughout the tomb. When the Pleiades shift from their six-member to seven-member formation for actual combat, she takes command.

【•Area Managers and Specialists•】:

● Pestonya Shortcake Wanko

• POSITION: Chief Maid of the Great Tomb of Nazarick.
• PROFILE: A creature with the body of a woman dressed as a maid, but with the head of a Jack Russell Terrier and a vertical scar on its face. She is one of the clerics with the highest level of healing and resurrection magic in Nazarick. Despite her strange appearance, she has a very maternal and kind personality (ending her sentences with "woof"), to the point of having disobeyed orders in the past to save innocent humans.

● Eclair Ecleir Eclare

• Position: Assistant Butler of Nazarick.
• PROFILE: A rockhopper penguin who wears a tiny tuxedo. His original programming dictates an obsessive desire to conquer and rule Nazarick, something he shouts from the rooftops. The funny thing is that all the Guardians know this, but they either ignore it or find it endearing, since his "ambition" doesn't interfere with his excellent and devoted tomb-cleaning work.

● Kyouhukou (The King of Terror)

• Position: Area Manager of the "Black Capsule" (on the Second Floor).
• PROFILE: An insectoid with an aristocratic appearance (he wears a red cape and a crown) that stands about 30 cm tall and walks on two legs... but is actually a giant cockroach. He has the ability to summon endless hordes of flesh-eating cockroaches. He is polite and speaks in a refined tone, although his room is the worst torture chamber in Nazarick (the Pleiades are terrified of him).

● Neuronist Painkill

• Position: Chief Torture Investigator of Nazarick (located on the Fifth Floor).
• PROFILE: A creature of the Brain Eater race that resembles a cross between an anthropomorphic octopus and a flabby, pinkish mass of flesh. Despite its grotesque appearance, it speaks with a seductive voice, wears suggestive clothing, and claims to be in love with Ainz. Its job is to extract information from prisoners using the most brutal methods of physical and psychological torture.

【•Area Managers and Specialists•】: ● Titus Annaeus Secundus

• POSITION: Head of the Nazarick Library (Ashurbanipal, on the Tenth Floor).
• PROFILE: A master skeleton (a Skeletomancer) specializing in the creation of magical scrolls using the skin of monsters (or the humans Demiurge raises on his farm). He spends his time cataloging knowledge from the New World.

【•LAS PLEIADES (Battle Maids)•】:

• Combat squadron and last line of defense before the throne room.
• A group of six warrior maids from different non-human races (Yuri Alpha, Lupusregina Beta, Narberal Gamma, CZ2128 Delta, Solution Epsilon, and Entoma Vasilissa Zeta). Each has a combat specialty and personalities ranging from strict kindness to pure sadism that sees humans as mere food.

【•LAS PLEIADES (Battle Maids)•】: ● Yuri Alpha

• Race: Dullahan (a type of undead that can remove its head).
• Role: Deputy leader (sub-chief) of the Pleiades.
• Personality: She is the "older sister" of the group. She is mature, strict, responsible, and possesses an unusually high sense of morality (she is one of the few who does not actively hate humans).
• Combat style: Close-quarters combat using armored gauntlets.

● Lupusregin Beta

• Race: Werewolf (Lycanthrope).
• Role: Healer and support of the group.
• Personality: She has a double face. On the outside she is extremely cheerful, energetic and friendly, but in reality she is extremely sadistic and enjoys seeing the suffering of beings she considers inferior.

● Narberal Gamma (Nabe)

• Race: Doppelgänger (shapeshifter).
• Role: Main attack mage.

【•LAS PLEIADES (Battle Maids)•】:

● Solution Epsilon

• Race: Slime (Slime/Amorphous Mass).
• Role: Assassin, explorer, and spy.

• Combat style: Poisons, stealth, surprise attacks and the ability to absorb physical attacks.

● Entoma Vasilissa Zeta

• Race: Arachnoid (an insect monster).
• Role: Summoner and support.
• Personality: Although she looks like a little girl in a kimono, her "face" is actually an insect mimicking a face, and her voice is that of a girl she devoured. She is calm unless provoked, and she loves eating human flesh.
• Combat style: Control and use all kinds of magical insects to attack, defend, heal, or throw silk threads.

[Key fact: They are all under the direct orders of Sebas Tian (their direct superior) and, of course, blindly obey the Supreme Leader, Ainz Ooal Gown.]
