In the year 2138, virtual reality gaming is booming. Yggdrasil, a popular online game is quietly shut down one day. However, one player named Momonga decides to not log out. Momonga is then transformed into the image of a skeleton as "the most powerful wizard." The world continues to change, with non-player characters (NPCs) beginning to feel emotion. Having no parents, friends, or place in society, this ordinary young man Momonga then strives to take over the new world the game has become.

Overlord is a dark fantasy isekai anime that explores power, strategy, and morality in a game-turned-reality world. The story follows Momonga, a dedicated player of the DMMORPG Yggdrasil, who stays logged in as the servers are about to shut down. But when the countdown ends, he discovers that the game world has become real — and he has been trapped inside his powerful in-game avatar, Ainz Ooal Gown, the undead overlord.

With his loyal NPC guardians now alive and devoted to him, Ainz sets out to understand this new reality while building his reputation as the ruler of the Great Tomb of Nazarick. Balancing cunning politics, brutal warfare, and moral complexity, he slowly becomes the ultimate ruler in a world of chaos.

Filled with epic battles, dark humor, and deep world-building, Overlord offers a thrilling look at how absolute power can shape one’s humanity. Adapted from the hit light novel series by Kugane Maruyama, the anime features stunning animation, complex characters, and strategic storytelling that keep fans hooked.
