Story
A few years after the final battle between Gaitoshin Wing and Baroqugun, a new threat arises. The moon suddenly becomes red and the previously inactive D-Dolls reactivate and attack the Kingdom of Lacroa. Along with their sudden reactivation comes Divine Knight Wing, currently half of the Guardian God Sunborn, and Selenis Knight Neo Gundam, pilot of Elgaia and Shuffle Knight, who arrives to explain that Saddrac is being targeted.

Chapters
The knight, known as Knight Gundam Barbatos, attacks Neo Gundam so he could "die for his sins", which confuses the latter. During their fight, he happens to see an aristocrat named Kudelia, becomes distracted, and is defeated by the mysterious Masked Knight. Masked Knight had been brought back earlier by Warrior Trowa and Fencer Wu Fei. Barbatos is captured and imprisoned. During a visit from Kudelia and Neo, he explains that Kudelia is actually a descendent of those who escaped the moon during the war with the Gjallarhorn Empire and calls Neo a traitor for deserting the people. Suddenly, Lacroa Castle is attacked by Gjallarhorn's forces and Neo heads out in Elgaia.
