On the night his favorite MMORPG is scheduled to be shut down, veteran player Momonga stays logged in until the clock hits zero. The screen goes dark for only a few moments before he finds himself completely immersed in the online world of Yggdrasil. Left with all of his character’s devastating powers, total dominion over his loyal NPCs, and nothing better to do…Momonga decides to try his hand at taking over the world.

All the hours he’s spent grinding and dungeon crawling have certainly paid off, and as he tests his strength on local rogues and legendary beasts he comes to realize that not one opponent can stand against his might. Embracing his new identity as the fearsome mage Ainz Ooal Gown, Momonga continues his search for bigger, badder adversaries. Leaving the people of Yggdrasil to wonder—who exactly is trapped with who?

A theater manners short bundled with the recap movie's BD/DVD releases. Each film had its own short with slight differences (eg. Fushisha no Ou had a smiling Shalltear but the Shikoku no Eiyuu one showed her sneering). Due to the minimal changes between the two, resulting in only a few seconds of alternative footage, MAL will reflect it as a single episode as the blunt majority was identical.
