("Demon King From Today [Onward]") is a Japanese series of light novels written by Tomo Takabayashi, which have been adapted into an anime series released domestically by Geneon USA, a manga and a series of audio dramas. As announced on March 10, 2007, there will also be an OVA released based on the novels. The anime series was produced by Studio Deen and aired across Japan on NHK and the anime television network, Animax, which also aired the series across its respective networks worldwide, including Hong Kong, Southeast Asia, and other regions including India, where the series goes by the name God(?) Save Our King!. The series has been licensed for North American distribution by Geneon under the name Kyo Kara Maoh! - God(?) Save Our King!(sic). Geneon ceased production of all titles in late 2007, leaving three volumes of the second season unreleased on DVD in North America. On July 3, 2008, Geneon Entertainment and Funimation Entertainment announced an agreement to distribute select titles in North America. While Geneon Entertainment will still retain the license, Funimation Entertainment will assume exclusive rights to the manufacturing, marketing, sales and distribution of select titles. Kyo Kara Maoh! was one of several titles involved in the deal. The story follows the adventures of 15-year old Yuri Shibuya (渋谷　有利, Shibuya Yūri), an average high school student whose passion in life is baseball, as he discovers his future in a world where demons and humans are fighting against one another.
