Mobile Suit Gundam SEED X Astray

A Gundam suddenly appears before Lowe Guele of the Junk Guild and his companions. Canard Pars, a young man who says he is searching for Kira Yamato, attacks Lowe and the others without warning and then leaves. After that, Lowe and the others take on a new job, but the client's ship is attacked by Serpent Tail, and the head of the Gundam they are supposed to deliver is stolen. Prayer Reverie, the young representative aboard the ship, asks Lowe and the others to recover the stolen head.
