Code Geass: Lelouch of the Rebellion (コードギアス 反逆のルルーシュ Kōdo Giasu: Hangyaku no Rurūshu), often referred to as simply Code Geass, is a Japanese anime series created by Sunrise, directed by Gorō Taniguchi, and written by Ichirō Ōkouchi, with original character designs by manga authors Clamp. Set in an alternate timeline, the series focuses on how the former prince Lelouch vi Britannia obtains a power known as Geass and decides to use it to obliterate the Holy Britannian Empire, a superpower that has been conquering various countries.
Code Geass first ran in Japan on MBS from October 5, 2006, to July 28, 2007. Its sequel series, Code Geass: Lelouch of the Rebellion R2 (コードギアス 反逆のルルーシュR2 Kōdo Giasu Hangyaku no Rurūshu Āru Tsū), ran as a simulcast on JNN stations (like MBS and TBS) from April 6, 2008 to September 28, 2008. The series has also been adapted into various manga and light novels with the former showing various alternate scenarios from the TV series. Bandai Entertainment also licensed most parts from the franchise for English release in December 2007, airing the two TV series on Adult Swim. Most manga and light novels have also been published in North America by Bandai. At the Code Geass 10th anniversary event on November 27, 2016, it was announced that the series will be receiving a new anime, along with a compilation film trilogy in 2017 that will recap the events from both seasons of the anime series. The new anime, titled Code Geass: Lelouch of the Resurrection (コードギアス 復活のルルーシュ Kōdo Giasu: Fukkatsu no Rurūshu), will take place a few years after the events of the Zero Requiem.
The anime television series has been well received in Japan, selling over a million DVD and Blu-ray Disc volumes. Both seasons have won several awards at the Tokyo International Anime Fair, Animage Anime Grand Prix, and Animation Kobe event. Critics have praised the series for its large audience appeal as well as the cross conflicts shown among the main characters and the moral questions presented.
