The Beginning of Nazarick’s Dark Fantasy Reign

Overlord: The Undead King is the first recap film in the Overlord anime franchise, retelling the opening half of Season 1 while refining several scenes with updated visuals and theatrical presentation.

Released in 2017 by Studio Madhouse, the movie condenses the early events of the anime into a faster-paced cinematic format focused on Ainz Ooal Gown’s arrival in the new world and the awakening of Nazarick.

Although the film does not introduce a completely new storyline, it serves as a streamlined retelling of the franchise’s beginning while preserving the dark fantasy atmosphere and psychological themes that made Overlord popular.

The movie primarily focuses on:

• The shutdown of Yggdrasil
• Nazarick’s transformation
• Ainz adapting to the new world
• The introduction of the Floor Guardians
• The creation of the warrior identity “Momon”

At its core, The Undead King explores the moment where an ordinary player slowly begins becoming something far more terrifying.

Story Summary

The story begins inside the popular virtual reality MMORPG Yggdrasil, moments before the game’s official shutdown.

Momonga, the guild master of Ainz Ooal Gown, chooses to remain logged in inside the Great Tomb of Nazarick until the final seconds.

However, after the shutdown time passes, the game world does not disappear.

Instead, Momonga discovers that:

• The NPC guardians have become sentient
• The world now functions like reality
• He can no longer log out
• His avatar body has become truly undead

Taking the name Ainz Ooal Gown, he begins investigating the mysterious new world while maintaining the image of a supreme ruler before Nazarick’s guardians.

The movie introduces major characters including:

• Albedo
• Demiurge
• Shalltear Bloodfallen
• Cocytus
• Aura
• Mare
• Sebas Tian

As Nazarick awakens, Ainz begins testing the rules of the world while searching for signs of other former players.

At the same time, the Floor Guardians display absolute loyalty toward him, treating even his smallest actions as divine strategy.

The film also follows Ainz creating the armored adventurer identity “Momon” to gather information about nearby kingdoms and human civilization without revealing Nazarick’s existence.

Through these adventures, the movie establishes the massive gap between Nazarick’s overwhelming power and the ordinary inhabitants of the world.

While humans fear monsters and struggle for survival, Nazarick possesses magical abilities capable of changing the balance of entire nations.

One of the strongest aspects of the film is the contrast between Ainz’s internal uncertainty and the terrifying image he projects outwardly.

Although he often feels confused and improvises decisions, everyone around him interprets his actions as flawless genius.

This misunderstanding becomes one of the defining elements of the Overlord franchise.
