Yggdrasil is a popular virtual reality game that enthralled players for ten years -- but now it’s going offline. Protagonist Momonga is the powerful skeleton-based wizard that headed one of the strongest guilds, Ainz Ooal Gown, and he’s not ready to say goodbye to the game.
He decides to remain online until the servers go down -- but at the stroke of midnight, he’s still in the game! Suddenly he can’t access the real world, and the previously silent NPCs are now quite animated! With nothing waiting for him in real life and armed with powerful magic, Momonga decides to explore his new not-so-virtual reality -- and take it over.
