The year is TCY 412, and a long age of peace is broken when mysterious and powerful fleets of starships suddenly orchestrate a coup d'état against the Transbaal Empire. The Transbaal homeworld is surrounded almost immediately, after which they begin an orbital bombardment of the capital. The orbiting space station (which seems to be the one used as the Moon Angel Troupe's base in the anime) is destroyed along with the Imperial palace, resulting in the death of King Gerald. The White Moon suffers significant damage, although it is later revealed that Lady Shatoyan was able to secure the White Moon in an impenetrable shield. Unable to defend Transbaal, the Elle Ciel along with the Moon Angel Troupe and their Emblem Frames escape in order to get help.
