Three years have passed since Casval, Artesia and Jimba fled to Earth and sought refuge in the castle of Don Teabolo Mass, an aristocrat and trusted friend of the Deikuns, in Andalusia, Spain; Teabolo adopts the children and renames them Édouard and Sayla, respectively. After Jimba is killed in an assassination attack by mercenaries hired by Kycilia Zabi, the Yashima Group, whose president is a good friend of Teabolo, offers to relocate an injured Teabolo and the children to Texas Colony at Side 5: Loum. Upon their arrival, the children meet Char Aznable, who bears a striking resemblance to Édouard. Tragedy strikes the children when they receive word that their mother Astraia has died. After Lucifer dies, Édouard bids farewell to Sayla before heading to the Loum military academy. Meanwhile, Dozle Zabi invites Ramba Ral to participate in a top secret development project that will change the face of Zeon's military forever.
