On a quiet and peaceful day, the skies split open and extradimensional beings, designated as the Unknown, launch a swift and brutal attack against humanity. To protect the future of the country, all of Japan's children are cryogenically frozen until the end of the war to keep them out of harm's way. Several years pass, and humanity has established a foothold in a corner of Japan, which now serves as the frontline of the war. No longer facing humanity's extinction, the children are awakened from their slumber. It is then discovered that, while in cryogenesis, the children had developed Worlds, supernatural powers unique to each person. The six most powerful children are given command of the reclaimed cities, using their powers to defend the strongholds against the continuing invasion. Childhood friends Ichiya Suzaku and Canaria Utara lead Tokyo, siblings Kasumi and Asuha Chigusa manage Chiba, and Maihime Tenkawa and Hotaru Rindou oversee Kanagawa. Over time, the almost routine attacks from the Unknown and the clashing personalities of the city heads and subheads cultivate petty rivalries, leading to constant arguments between the three cities. With the Unknown suddenly increasing the pressure of their attacks, the three cities' leaders must learn how to work together or risk losing the last line of defense against humanity's extinction.

As close encounters of the twisted kind between the residents of the planet Develuke (represented primarily by the female members of the royal family) and the inhabitants of Earth (represented mainly by one very exhausted Rito Yuki) continue to escalate, the situation spirals even further out of control. When junior princesses Nana and Momo transferred into Earth School where big sister LaLa can (theoretically) keep an eye on them, things SHOULD be smooth sailing. But when Momo decides she'd like to "supplement" Rito's relationship with LaLa with a little "sisterly love," you know LaLa's not going to waste any time splitting harems. Unfortunately, it's just about that point that Yami, the Golden Darkness, enters the scene with all the subtleness of a supernova, along with an army of possessed high school students! All of which is certain to make Rito's life suck more than a black hole at the family picnic. Unless, of course, a certain semi-demonic princess can apply a little of her Develukean Whoop Ass to exactly that portion of certain other heavenly bodies! (Source: Sentai Filmworks)
