Taking place shortly after Skull Heart, the series has Tobia and friends meeting Europa, the second wife of original Crossbone villain Crux Dogate, who warns of a revitalized Jupiter Empire invasion. Of particular note is the presence of the F-99 "Recordbreaker", a mobile suit based on the Crossbone Gundams, which is chronologically the first mobile suit to use the "Wings of Light" made famous by the V2 Gundam.
