Following a catastrophic earthquake twenty years prior, Tokyo, along with most of the world, has sunk into the ocean during a large-scale land subsidence. Aika Sumeragi is a salvage agent, a person who digs up submerged artifacts from the cities below. She works for a small company run by Gozo Aida, and takes on fairly dangerous jobs. In the first story, she and Gozo's daughter Rion, search for material called the Lagu. However they are captured by Rudolf Hagen, an effeminate but over-sexed man who wants to use the Lagu to transform the world, destroying its inhabitants, and replacing them with an army of young women called the Delmo Corporation who will carry his progeny. Alongside Rudolf is his obsessive sister Neena Hagen, who is jealous of Aika when Rudolf desires to have Aika for himself. Aika has a special bustier that, when activated, transforms into a battle bikini that gives her extraordinary fighting powers. Following the defeat of the Hagens, the Delmo Corporation girls seek other methods to foil Aika in episodic stories.

In reviewing the first volume, Chris Beveridge on wrote that he had to put his brain in a certain mode, likening the experience to watching Dumb and Dumber where "Instead of idiot humor we're watching this for the sheer amount of fanservice." with its "four gajillion panty shots" and that it was a "great deal of mindless fun".[8] He described Michikusa as "a waifish goofy ass boy who serves only one purpose: to be on screen and take time away from panty shots."[14]

Stig Hogset of THEM Anime Reviews wrote that the show should have been a guilty pleasure but ends up being more of an overdose: "EVERY action scene seems to end up with unconscious females lying with their butts poking up into the air." He called the villains the creepiest he has ever seen, but recommended the show only to those with a panty or ass fetish.[1] The Anime News Network reviewer wrote that "It's as if someone tried to make the most perverted anime they could without anyone actually being in any sexual situations. (Okay, so there are some.)", later adding that "The dub is weak and mistimed, and some of the minor characters just plain can't act." and recommended that the viewer watch titles from the company's Anime 18 productions instead.[3] Todd Douglass Jr. of DVD Talk likened Aika's transformation to that in Cutie Honey and called the series the "epitome of guilty pleasure anime". He found the show to be solid-looking with fantastic animation and character design. With regards to the audio, he thought the Japanese cast did a much better job with the material than the English cast, writing that the latter was "particularly bland and it didn't maintain the necessary spark for this kind of show."[7]
