Kujibiki Unbalance (くじびきアンバランス) is a three-episode original video animation spin-off of the Genshiken manga and anime series, as well as a series of three light novels by Genshiken anime collaborator Michiko Yokote.

Genshiken characters who are fans of Kujibiki Unbalance tend to refer to it by the shorthand name of Kuji-Un (くじアン).

Kujibiki Unbalance is meant to be a very stereotypical anime series, serving as both an homage to and a parody of the kinds of series that the otaku of Genshiken would enjoy.
The series was originally shown both as short "excerpts" within the Genshiken manga, as well as three full OVA episodes (labeled as episodes 1, 21, and 25 of an assumed 26-episode TV series) released to DVD with Genshiken in Japan. At Comiket 69, Media Factory announced the release of the second season of Genshiken, which was later clarified as being a 12-episode season of
