Special episode included with BD/DVD release.

Anime based on Otaku no Seiza: in Another World, on the Turbo CD, and Otaku no Seiza: An Adventure in the Otaku Galaxy, for the NES, which were two Role-Playing games, published by M&M, released in Japan in 1991 and 1993.

Somewhat based on the real story of how Gainax was founded, Otaku no Video addresses all aspects of an otaku lifestyle. Ken Kubo is a young man living an average life until he is dragged into a group of otaku. Slowly, he becomes more like them until he decides to abandon his former life to become king of otaku—the otaking! Mixed in are live-action interviews with real otaku, addressing every aspect of hardcore otaku life. Not only are anime and manga fans included, but also sci-fi fans, military fans, and other groups of Japanese geeks.
