Abunai Sisters: Koko & Mika (found CGI anime shorts; 2009)

Abunai Sisters: Koko & Mika was a series of CGI shorts created in Japan to promote tabloid celebrities Kyoko and Mika Kano, starring the two sisters as secret agents. Despite the series being created by acclaimed studio Production I.G (who also did work on Eden Of The East, Ghost In The Shell, and FLCL, among many other shows and movies), reception of the shorts was universally negative due to the poor quality of its CGI and writing, which consisted mostly of jokes about the lead characters' large breasts. The shorts ran on Japanese satellite network AT-X, but only the first two were ever shown, and they were pulled after a month on the air. It had no Japanese audio track, and was instead originally aired in English with Japanese subtitles.

The first episode is still available on official platforms such as Nico Nico Douga and Crunchyroll, and rips of the second episode exist elsewhere, but the rest of the shorts are now lost. A single DVD of the full show exists, but it is hard to find and expensive due to poor sales. (Despite offering bonuses such as figurines, discounts and shout-outs in the credits to the first 500 people to preorder the DVD, reports say that it only ever sold 265 copies.)

The full DVD is currently available at this Japanese online store: http://www.netprice.co.jp/netprice/library/goods/295372/ Be warned, it's pricey - 36,270 Yen is nearly $300 US.
