These are a series of 13 omake episodes of Gun x Sword, tied in very loosely to the plot, with the characters as chibi puppets. The main characters are Wendy and her turtle, Kameo, who is the size of a human in this series and is able to talk. All the episodes seem to center around analyzing various events in Gun x Sword and mocking the themes displayed. They are included on the DVDs.

Nine regular humans from different parts of the world are abducted and transformed into cyborgs with astounding powers for the purpose of being used as weapons. The nine cyborgs rebel and start to fight against their creators in the name of justice and world peace. Decades later, the nine cyborgs seem to be untouched by time, but they live in a world where "justice" has as many nuances as the number of people living on the planet. What is their place in the world now? "In the beginning was the Voice, and the word was Him; and all obeyed His word in great awe. But those who dwelt upon the land, through vanity, cunning and greed, attempted to build a multitude of towers whose tops reached unto heaven, and accumulated great wealth on earth. Scattering across the land and laying it to waste, man turned a deaf ear to His Voice. So He gave unto man an opportunity to atone for his misdeeds; and flame and smoke and the roar of a lion descended upon earth; and shattered the many towers to dust...."
