The Zaku, "The Father of all Mobile Suits", a title bestowed on to this mobile suit long after its creation & deployment to the battlefield; but this is not the story of the Zaku's exploits during the Zeon War of Independence, later called the One Year War. Neither is it the story of a new type of piloted, independently powered mobile machine. A machine that would be powered by a state of the art thermonuclear reactor, but due to the secrecy and inherent danger involved in developing a project of this kind, its development was outsourced to Hosioka, a small steelworks industrial plant and its employees, this is their story.

Principality of Zeon
- A number of Zabi family cameos are present in the manga, with most of the children of the Sovereign appearing in a televised Side 3 broadcast. Later in the story, Gihren is shown personally observing Zeonic's company demonstration of the Mobile Suit prototypes.
- In the same broadcast, next to Garma there is a young, fair-haired man who looks quite a bit like Char Aznable.
- Near the end of the manga, a panel showing Elliot Rem's working with the military to develop future MS has him sarcastically suggest placing a 'horn' onto commander-use units to distinguish them from rank-and-file.
