出渕裕
is a group consisting of five main writers and artists who work in the Japanese anime/manga field. The group was set up so that all the creators could retain full copyright to their work, achieve greater publicity for their work and sell their manga to anime sponsors for film production. The members are Masami Yuki, Yutaka Izubuchi, Kazunori Itō, Akemi Takada, and Mamoru Oshii. Together they worked on the anime series "Patlabor" and the two episode OVA "Twilight Q".
