Who Are the Nazarick's Floor Guardians in Overlord? Explained

The Floor Guardians are among the most powerful and recognizable characters in Overlord. Created by the guild members of Ainz Ooal Gown during their time in the virtual world of YGGDRASIL, these NPCs become living beings after the Great Tomb of Nazarick is transported to the New World. Each Guardian is responsible for protecting a specific floor of Nazarick while serving Ainz with absolute loyalty. Their immense strength, unique personalities, and unwavering devotion make them central to nearly every major event in the series.

Although they all answer directly to Ainz, the Floor Guardians differ greatly in appearance, abilities, and leadership styles. Some specialize in overwhelming magical power, while others excel in physical combat, strategy, or battlefield command. Together, they form Nazarick’s greatest line of defense and represent the military backbone of the Sorcerer Kingdom. Here’s everything you need to know about the Floor Guardians and why they are so important in Overlord.

Meet the Floor Guardians

The Floor Guardians are elite NPCs assigned to defend each level of the Great Tomb of Nazarick. They were individually designed by members of the guild Ainz Ooal Gown, giving every Guardian a distinct personality, combat style, and backstory. After arriving in the New World, they retain their memories and programming while developing genuine emotions, particularly their absolute respect and admiration for Ainz.

Albedo serves as the Overseer of the Floor Guardians, coordinating Nazarick’s military operations even though she is technically the Guardian of the Guardians rather than a specific floor. Exceptionally intelligent and fiercely loyal, she manages many of Nazarick’s political affairs while remaining deeply devoted to Ainz. Her strategic thinking makes her one of the organization’s most valuable leaders.

Shalltear Bloodfallen, the Guardian of the first through third floors, is considered one of Nazarick’s strongest combatants. As a true vampire, she possesses extraordinary physical strength, regeneration, and powerful divine-class equipment. Her confrontation with Ainz remains one of the most memorable battles in the series after she falls under mind control.

Cocytus guards the fifth floor and specializes in honorable melee combat. Wielding multiple legendary weapons, he values discipline, courage, and worthy opponents above all else. Despite his intimidating appearance, Cocytus frequently demonstrates compassion and respect toward those who prove themselves in battle.

Aura Bella Fiora and Mare Bello Fiore, the twin Dark Elf Guardians of the sixth floor, complement one another perfectly. Aura excels at commanding magical beasts and tracking enemies, while Mare is one of Nazarick’s strongest magic casters, capable of reshaping entire battlefields with devastating earth magic. Together, they form one of the tomb’s most versatile defensive teams.

Demiurge, the Guardian of the seventh floor, is widely regarded as Nazarick’s greatest strategist. His intelligence allows him to orchestrate complex military campaigns and political schemes while interpreting Ainz’s every action as part of an elaborate master plan. Much of Nazarick’s expansion throughout the New World is guided by Demiurge’s careful planning.

Finally, Victim, the Guardian of the eighth floor, appears physically weak but possesses abilities designed to support Nazarick’s ultimate defenses. Although rarely involved in direct combat, Victim’s unique sacrificial powers make him a critical component of the tomb’s security system during emergencies.

Together, the Floor Guardians embody the overwhelming power of Nazarick. Each one is capable of defeating armies on their own, yet their greatest strength comes from their complete loyalty to Ainz Ooal Gown and their willingness to work together. Their combination of immense power, distinct personalities, and strategic brilliance makes them some of the most memorable characters in Overlord and one of the strongest organizations in modern fantasy anime.
