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.
After the war against Yamikoutei (闇皇帝), Ark is ruled by evil forces. Desecendents 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. One day, when Retsumaru's family was threatened, a sword from the armour set appeared in front of Retsumaru, and so the story began.
- Volume 1:Years ago, the forces of good and evil met in a climactic battle. Now, Ark is ruled by various tyrannical warriors. Retsumaru, son of the legendary hero Rekka Musha Gundam, sets out to form a new band of heroes and restore Ark's former glory.
- Volume 2: Uniting with their fathers, the new generation of defenders prepare to strike the final blow against the demonic warlord Capiturn.
- Volume 3:With the defeat of Capiturn, the young defenders have gone their separate ways. However, Retsumaru soon becomes aware of an even greater danger. Matured by his adventures, Retsumaru must launch a covert mission into the heart of enemy territory.
