Descendants of the Seven of Light defenders scattered across the land, in search of the Bukabuka (武化舞可) armour that can bring peace to the world.

This form of the storyline was backed up by a model kit line which featured all of the fathers and sons, as well as their Mobile Musha secret weapon.

Each of the kits had elements of interchangeable armour, with a story point being that one certain combination gave the central father and son pair a Dai-Shogun form.

In contrast to the earlier Musha Maruden series, a fair number of Gundams in the story did not receive model kits.

Also scrapped were more gimmicks for Kirimaru (including a pet dragon, a bird-like mask similar to Barzam Shogun's and a Base Jabber sled) and more armour for Retsumaru which seemed to imply he would grow up to be the First Gundam Dai-Shogun seen in Musha Senki.

The series will reuse molds from this line with additional parts to make the Gundams resemble actual historical samurai such as Takeda Shingen.

The line instead opted to reuse two unrelated Dai-Shogun kits from previous BB Senshi Musha Gundam series.
