Log Horizon (Japanese: ログ・ホライズン Hepburn: Rogu Horaizun?) is a Japanese Anime television series adaptation of the novel series written by Mamare Touno and published by Enterbrain in Japan since 2011.
Even as Shiroe slowly learns the secrets behind the creation of the World Fraction spell, the origin of the Demi-humans, and how his own actions in the Real World have affected the world in which he now dwells, the seeds of thought he's planted in the minds of others begin to bear fruit. In the midst of this MMORPG turned real, an unassuming princess may prove to be the key to ultimate victory.
