Ren is an avid gamer who suddenly finds himself transported inside the VR game L.O.L., but this isn't the kind of game world where knowing the mechanics guarantees an easy life. Years after its release, not a single player has ever managed to clear the game. Its difficulty is so notoriously unforgiving that players consider it practically impossible, and Ren doesn't even have time to process what's happened before he's thrown into a tutorial with a completion rate of less than forty percent. Now the mistakes that once meant nothing more than a game over can cost him his life. With no room for error, Ren must put everything he remembers about the game to use, exploiting his knowledge of its mechanics, skills, characters, and deadly events to survive. Trapped in a world designed to defeat even the most dedicated players, Ren sets out to accomplish what no one ever could: conquer the impossible game and become the hero who saves its world.
