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 in Japan on October 5, 2009. It was followed by an OVA in September 2010, a 2nd TV anime series from October 2010, an anime film in June 2011, and a third TV anime series in 2012.
