Galaxy Angel II: Zettai Ryōiki no Tobira is the first game of the Galaxy Angel II series that is set 4 years after the end of the previous game, Galaxy Angel Eternal Lovers. It features a brand new cast of Angels, the Rune Angel Troupe, and primarily takes place in a parallel universe called NEUE. The new Rune Angel Troupe features Emblem Frames from NEUE and act as the successor unit to the now disbanded Moon Angel Troupe. As for the parallel universe NEUE, it is linked to EDEN through a space called ABSOLUTE, which is the central hub to which all parallel universes are linked. This is connected to the title which roughly translates to Galaxy Angel II: The Door to Absolute. The story begins with Kazuya Shiranami's arrival to the Luxiole as the newest and first male member of the newly formed Rune Angel Wing. When contact with Milfie inside ABSOLUTE is cut off and when previous Moon Angel Wing member Forte Stollen announces a coup d'etat on the NEUE capital planet of Seldar, Tact, Kazuya, and the Rune Angel Wing respond and are called into action.
