As a child, Riki Naoe shut himself from the world, thanks to a diagnosis of narcolepsy following the tragic deaths of his parents. However, Riki is saved when, one fateful day, a boy named Kyousuke recruits him into a team who call themselves the Little Busters. Accompanied by Masato, Kengo, and Rin, these misfits spend their childhood fighting evil and enjoying their youth. Years pass, and even in high school, the well-knit teammates remain together. Kyousuke decides to re-ignite the Little Busters by forming a baseball team as it will be his last school year with them. They have a problem though: there aren't enough members! The tables have turned, for it is now Riki's turn to reach out and recruit new friends into the Little Busters, just like Kyousuke had once done for him. Then, an omen surfaces—Rin finds a strange letter attached to her cat, assigning them the duty of uncovering the secret of this world by completing specific tasks. Just what is this secret, and why is it being hidden? It's up to the Little Busters to find out!

In the blink of an eye, thirty thousand bewildered Japanese gamers are whisked from their everyday lives into the world of the popular MMORPG, Elder Tale, after the game's latest update—unable to log out. Among them is the socially awkward college student Shiroe, whose confusion and shock lasts only a moment as, a veteran of the game, he immediately sets out to explore the limits of his new reality. Shiroe must learn to live in this new world, leading others and negotiating with the NPC natives in order to bring stability to the virtual city of Akihabara. He is joined by his unfortunate friend Naotsugu, having logged in for the first time in years only to find himself trapped, and Akatsuki, a petite but fierce assassin who labels Shiroe as her master. A tale of fantasy, adventure, and politics, Log Horizon explores the elements of gaming through the eyes of a master strategist who attempts to make the best of a puzzling situation.

After being trapped in the world of Elder Tale for six months, Shiroe and the other Adventurers have begun to get the hang of things in their new environment. The Adventurers are starting to gain the trust of the People of the Land, and Akiba has flourished thanks to the law and order established by Shiroe's Round Table Alliance, regaining its everyday liveliness. Despite this success, however, the Alliance faces a new crisis: they are running out of funds to govern Akiba, and spies from the Minami district have infiltrated the city. As formidable forces rise in other districts, there is also a need to discover more about the vast new world they are trapped in—leading Shiroe to decide that the time has come to venture outside the city. Accompanied by his friend Naotsugu and the Sage of Mirror Lake Regan, the calculative Shiroe makes his move, hoping to unravel new possibilities and eventually find a way home.
