List of Sora no Otoshimono episodes

Sora no Otoshimono is an anime TV series based on the manga series of the same name by Suu Minazuki. The manga is serialized in Kadokawa Shoten's manga magazine Shōnen Ace. The anime is produced by AIC, directed by Hisashi Saito, composed and written by Yūko Kakihara, and characters by Yoshihiro Watanabe. The story revolves around Tomoki Sakurai, a young boy whose life of peace and quiet is cut short when he encounters a U.M.A (Unidentified Mysterious Animal) named Ikaros, an Angeloid who fell from the sky.

13 episodes were aired on Teletama and Chiba TV between October 4 and December 27, 2009, with subsequent broadcasts on KBS, TV Kanagawa, Sun Television, TVQ, Tokyo MX and TV Aichi. English-subtitled simulcasts were provided by Crunchyroll, but were later removed by the publisher. Seven DVD compliation volumes were distributed by Kadokawa Pictures between December 25, 2009 and June 25, 2010, with Limited Edition releases also sold.

An OVA episode entitled "Project Pink" was bundled with the Limited Edition release of volume 9 of the manga as a DVD on September 9, 2010. The episode was considered "too dangerous" for TV and it was originally planned to be on the seventh DVD volume, but it was later removed and replaced with a TV version of the final episode and live footage of the SoraOto live concert which took place on March 20, 2010. The anime is licensed in North America by Funimation Entertainment, who will be releasing it under the title of Heaven's Lost Property in 2011.

A second season of the anime, entitled Sora no Otoshimono: Forte (そらのおとしもの f （フォルテ）), has been announced on reprinted copies of the manga and the first episode aired on Teletama and Chiba TV on October 1, 2010. Crunchyroll will provide English-subtitled simulcasts for the second season as it did with the first season. Forte has also been licensed by Funimation and will also stream the series on their video portal.

Fourteen pieces of theme music were used for the first season: an opening theme and thirteen ending themes, one for each episode aired. The opening theme is "Ring My Bell" by Blue Drops, consisting of singers Hitomi Yoshida and Ikaros (Saori Hayami). For the second season, the opening theme for episode 1 is a cover of "Ring My Bell" sung by Soichiro Hoshi, while the main opening theme is "Heart no Kakuritsu" by Blue Drops. Multiple ending themes will be used for each episode, as it did with the first season. The ending theme for each episode can be found in the episode list.
