Majestic Prince (マジェスティックプリンス, Majesutikku Purinsu) is a Japanese manga written by Rando Ayamine and illustrated by Hikaru Niijima about a team of eccentric, genetically enhanced youngsters selected to pilot some experimental mecha to defend Earth against an alien, hostile race. An anime adaptation was announced in the November 2012 issue of Weekly Hero's magazine under the expanded title of Galactic Armored Fleet Majestic Prince (銀河機攻隊 マジェスティックプリンス, Ginga Kikōtai Majesutikku Purinsu). The anime has been licensed by Sentai Filmworks. It began airing on TV on April 4, 2013, and is being streamed with English subtitles by Crunchyroll and the Anime Network. In July 2016 the episodes were rebroadcast, with a new "25th episode" on September 29, 2016, with events leading to a feature film to be released in November.
Ginga Kikoutai: Majestic Prince takes place in the latter half of 21st century when humans leave the Earth and begin to live in space. In order to adapt to the environment in space and deal with the hostile aliens in Jupiter, scientists have created genetically engineered children called "Princes." These children are artificially raised, and they are all trained to be pilots of armed robots called "AHSMB" (Advanced High Standard Multipurpose Battle Device).
