Two animated shorts each featuring the characters and mecha of the Astray R and Astray B manga/novel series, as well as mobile suits from the Gundam SEED MSV (Mobile Suit Variations) model kit series.

In the first short, Lowe Guele and the Junk Guild make a stop at an mobile suit parts auction on Earth where Lowe purchases a head taken from a modified BuCUE suit which, when attached to the arm of his Astray Red Frame, acts as a dual beam saber. Lowe tries to decrypt some combat data contained in the head, but is shortly engaged by, and goes into combat with several ZAFT suits including a CGUE D.E.E.P. Arms.

In the second short, Blue Frame pilot Murakumo Gai engages and, with the help of his fellow Serpent Tail mercenaries, traps a GINN High Maneuver Type. He then faces off with the legendary Edward Harrelson, who pilots a Sword Calamity Gundam and has just finished destroying a fleet of ZAFT ships.
