Yūya Yoshikawa

Three eight-year-old girls, Mao, Misora and Sylvia, try to defend the earth against invading aliens. The world's defense has fallen to unlikely straits because the aliens are excessively cute, of which combat engagements are televised: if the forces battling the aliens were not cute themselves, the general public would revolt, as it would be seen as "bullying". Consequently, three military leaders chose their granddaughters to be the defenders, fittingly, becoming a team even cuter than the aliens. They each have a clover-shaped badge that enables them to transform.

Denizens of Lux have come to call it "The City" and treat it as a sentient force. Three factions vie for control of the city: the Organo, a strictly professional conglomerate with ties to the criminal underworld in the prosthetics business; the Union, a fanatical populist group interfering with Organo's affairs; and Racan, a marauding group of Texhnolyzed youths.
