The twelve protectors of the Orbs, built by the Mukashi to guard their knowledge of their species' development, the Shinwa are known as the "Legendary Gundams" in the FCC era. Built early in the CC era by the Mukashi's best scientists, they carefully studied the history of the Mukashi in order to better understand what they were protecting. However, they soon came to the conclusion that the Mukashi had forgotten or abandoned their past, and decided that they needed to be reminded. Their decision soon sparked their untamed, destructive power, resulting in a surface-wide genocide of the Mukashi population. Two of their number were unable to withstand against the desperate counter attack, and thus died, but it only served to spur on the rest of the Shinwa until they could find no more on the surface, and eight of them retreated to their comrades' resting place, falling into stasis until they were reactivated thousands of years later by foreign scientists. Eventually, this sparked into the famous Seitoso War, in which they fought against each other until the end of the CC calendar. However, unlike the rest of the population's belief, they separated themselves and went their different ways to try to avoid conflict, faking their deaths several times to avoid being sought out for combat. The Shinwa are composed of Aijounetsu, Okubasho, Sagasurei, Itteihimeirei, Jiyounamaru, Kyouufushi, Tsuretekuru, Inochishoshu-gu, Shukumeisai, and Likimas; the other two Shinwa's names are not recorded.
Generally in the comic, when one says "Shinwa", it is in reference to a particular Legendary Gundam, usually their own ancestor. Some of the Shinwa's descendents, depending on the formatting of their programming data, develop a frighteningly large amount of skills similar to their related, oldest heritage, and are thus considered a reincarnate, or Shujinko. The Shinwa are also called "Sei" or "Seizen" by their respective clan members.
