Johnny Ridden survived through the fierce battle of A Baoa Qu although his MS-14B Gelgoog High Mobility Type was badly damaged by the FA-78-1 Gundam Full Armor Type's overwhelming firepower. With the aid of a comrade, he reached a Dolos-class carrier where he was reunited with his MS-06R-2 Zaku II High Mobility Type, which was modified by a mechanic and nicknamed the MS-06R-2 Zaku II High Mobility Type "Full Bullet Zaku".

Sequel to Crossbone gundam. Unlike the other two episodes of the "crossbone saga" this volume focuses on several short stories that don't have such a great effect over the jupiter war.

While the book itself is not meant to be comedy, but the "character" of the stories is (generally) much less serious than either the first or the third part of the crossbone series.

The stories are pretty varied in both, placing and characters. Due to that the series is actually decently strong in the cameo department.
