Sora no Otoshimono (Lost Property of the Sky) is a TV anime series based on a "heartful" comedy manga about a fallen - and rather hot looking - angel, erroneously classified as an "unidentified mysterious animal" (UMA) at first. The anime adaptation was produced by studio AIC A.S.T.A., and began airing on October 5, 2009. This particular trailer promotes the anime's first DVD volume that's coming out in Japan on December 25, 2009.
