The year is 2030. Full-dive devices have become commonplace.
Maybe it's just human nature to seek entertainment, but countless games made with these devices have sprung up. Among them, a game called Old World stood out for its incredible freedom, engaging gameplay, and enormous map, roughly the size of the combined landmass of Europe and Asia. It soon became a worldwide sensation.
And the girl was a devoted player of the game.
Though, to put it that way...
Why did I end up in another world after taking a nap?!
Girl: It's not like I wanted to show off! You all made me do it!
This is the story of a max-level player beating the daylights out of a bunch of low-level residents in another world.
And maybe I'll do a little yuri on the side, too, the girl thought.
