B-ko's father Daitokuji Hikaru, a billionaire industrialist has big plans this time around. B-ko's obsession with C-ko finds another outlet, as she uses her genius intellect to help the Alpha Cygnans repair their spaceship, since C-ko has developed a soft spot for the stranded Napolipolita and D. The Alpha Cygnans have turned their ship into a posh 30,000 room hotel, but long only to return home. It is summertime, so a visit to a swimming pool is a good opportunity to cool off. The heroines are also being stalked by a steadily-growing number of mysterious men in white suits, who all attempt to appear inconspicuous by nonchalantly reading newspapers. Later, they reveal themselves as spies, their mission being the capture of the Cygnan super-technology. The climax involves the military forces — being manipulated by Daitokuji Hikaru — attacking the Alpha Cygnan ship with a giant experimental mecha named the Queen Margarita (whose blueprints he confiscated from B-ko) in a greedy attempt at seizing their alien technology. This results in one truly classic moment, in which B-ko's father flies into the fray wearing one of his daughter's revealing Akagiyama battle suits and attempts to catch the Ship — which is plummeting back to Earth — and ends up blowing out his back.
