Musha Gundam
The actual story is a revival of the very first Musha Gundam storyline focusing on Ark's "Seven of Light" defenders, seven brave Musha Gundams who defend the land of Ark by order of the Shogundam. This basic story was presented in Musha Retsuden Zero, whilst Musha Retsuden was set a few years later. Just about all of the legendary defenders have fathered sons and are training them to one day assume their father's roles.
