Characters in the Cosmic Era manga spinoffs.

Rondo Gina Sahaku and Rondo Mina Sahaku were fraternal twins and Coordinators who were members of the Orb Union's nobility. While Rondo Gina was male and Rondo Mina was female, the two looked nearly identical. In addition to their appearance, they also shared the desire for Orb to rule the Earth Sphere. To achieve that goal, they acquired several powerful Earth Alliance mobile suits, either by theft or through secret arrangements with Blue Cosmos leader Murata Azrael, and also attempted to retrieve Orb's lost MBF-P02 Gundam Astray Red Frame and MBF-P03 Gundam Astray Blue Frame, an effort that cost Rondo Gina his life at the hands of Blue Frame pilot Gai Murakumo.

With the death of her brother, Mina's ambitions waned and she was content to simply defend the Ame-no-Mihashira and protect the refugees from terrestrial Orb who had gathered there after its fall. After the war's end, Rondo Mina dispersed the forces under her command to await the restoration of the Orb Union.

At their height, the Sahaku family's military forces consisted of the space fortress/mobile suit factory Ame-no-Mihashira (August Pillar of Heaven, named from a Japanese creation myth), the battleship Izumo, the MBF-P01-Re2<AMATU> Gundam Astray Gold Frame Amatu, a GAT-X133 Sword Calamity, a GAT-X255 Forbidden Blue, a GAT-333 Raider Full Spec, two GAT-01D Long Daggers, and numerous MBF-M1 and MBF-M1A Astrays.
