Description
Bartz Ryan is one of thirteen children stranded in the aftermath of the Astrogaters' attack on the human colony Clayad in 2058. He fled aboard the training combat spaceship Janous alongside the other child survivors.

He brings prior experience operating Round Vernian mecha, knowledge gained from earlier training. This expertise proves crucial, as he takes responsibility for instructing other children, notably Roddy Shuffle and Maki Lowell, on how to pilot these machines using the ship's available VR training systems.

His leadership style and military knowledge sometimes result in him being characterized as a Sergeant Rock-type figure, though he personally maintains that he is a nice guy. He is also identified as the son of a character listed as "Barts' Father".

He serves as a central figure within the group of child survivors, playing a critical role in their efforts to operate the Janous and its mecha for their journey.
