In contrast to the central conflict featuring the Earth Alliance, ZAFT, and Orb Union in Mobile Suit Gundam SEED, the Astray series centers around the three MBF-P0x mobile suit prototypes, with a particular emphasis on their individual pilots and groups. These characters primarily exist on the periphery of the main SEED narrative. Lowe Guele of the Junk Guild pilots the MBF-P02 Astray Red Frame, while Gai Murakumo of the mercenary group Serpent Tail operates the MBF-P03 Astray Blue Frame. Orb nobleman Rondo Ghina Sahaku, the primary antagonist of the Astray tale, uses the third mobile suit, the MBF-P01 Astray Gold Frame, before his twin sister Rondo Mina Sahaku takes over control.
