In the fashion of sci-fi movies. Reinforcements from ACROSS Headquarters turn out to be an invasion by the incredibly cute but deceptively tyrannic Puchuu Imperium, and Excel stages a brave, if somewhat misguided, raid on their Mothership. Meanwhile, Nabeshin is also aboard in order to help an old friend escape the clutches of the Puchuus. At the end, the aerial alien invasion force is destroyed, Excel is being held as a prisoner of war, and Ilpalazzo admits Hyatt to ACROSS' ranks.
