Galaxy Angel (, Gyarakushī Enjeru?) is a bishōjo sci-fi/comedy anime, manga and dating sim series by BROCCOLI. It was created in July 2000, when Broccoli launched the multi-platformed project called Project G.A. The anime and Galaxy Angel Party manga comprise a comedy story in an alternate universe, while the games and the regular manga have a serious and involved romance/action plot.
A sequel to the game trilogy was released in June 2006, entitled "Galaxy Angel II: Zettai Ryouiki no Tobira", and stars an entirely new cast, the "Rune Angel Troupe", and a new feature that combines the new Brave Heart frame with any of the Angels. Each of the Rune Angels has a connection to one of the Galaxy Angels, such as Apricot Sakuraba, the younger sister of Milfeulle Sakuraba. Just like the original Galaxy Angel, the Galaxy Angel II series will have multiple games and already has a manga adaptation and comedic anime spinoff, both of which are currently running. The second Galaxy Angel II game was released in October 2007 entitled Galaxy Angel II Mugen Kairou no Kagi.
The success of the video game and anime series influenced the creation of a manga series based on the video game universe.
In Japan, the series became so popular that a musical based on the series was made. Entitled "GALAXY ANGEL ~The Musical, it debuted in March and December 2005, and featured cast members who also worked on Galaxy Angel II.
