Elder Tales is an online fantasy RPG that has become popular worldwide. But when its twelfth expansion package, "Cultivate the Noosphere," is installed, thirty thousand players in Japan are trapped inside.
Among them is grad student Shiroe, who isn't very good at interacting with others. But to survive in a world full of monsters, he forms a guild called "Log Horizon" with an eclectic group of other players.
After having the vast majority of their lands captured by the other races and being driven to the brink of extinction, Sora and Shiro challenge these one\-of\-a\-kind battles of the intellectual powers in order to save Humanity.
