According to Rikudou, Victor Entertainment solicited Shonen Gahosha about adapting Excel Saga into an anime, and the two companies approached him. He agreed, but asked that the anime have a different storyline from the manga, which was and remains on-going. Rikudou says he is very pleased with the adaptation and that he sees "much appeal in the anime world." Shinichi Watanabe, the director, was for his part surprised to learn that he was specifically requested by Yousuke Kuroda, one of the show's writers. He adds that his first thought on looking at Rikudou's material was, "Wow, there's so much here that can't be broadcast on TV."
