The anime short Xi Avant was created and directed by Kenji Kamiyama at studio Production I.G, and was first screened in Japanese theaters with the stereoscopic 3D conversion of the Ghost in the Shell: Stand Alone Complex - Solid State Society anime film. The story of Xi Avant is set in Spain and other locales in the near future, and is tied to the NTT Docomo mobile phone network's next-generation Xi data service.
