The story will feature Leonard Fiennes, who previously appeared in another side story of Gundam Double O - Gundam 00P, but as a Super Soldier pilot from HRL. We see the grown up version of him in Celestial Beings pilot suit in this new side story.
Also shows Arios Ascalon, GRM Gundam and Cherudim Gundam Saga, all which are from "Gundam 00V".
Also, I'm not sure if they are from the same new manga, but the sort-of Gundam head design of Descartes Shaman's Mobile Armor Gadelaza is revealed. GN-XIV (?) with new cannon equipment and Rasiel Gundam with new backpack equipment are shown as well.
