Aika Sumeragi, a salvager for hire who gets caught up in a plot for world domination. It is well known for its copious amounts of fan service, specifically the camera angles on panties of the many female characters that populate the show.

Tokyo has been sunk into the ocean, along with most of the world, during a large-scale land subsidence! Aika Sumeragi is a salvager who works for a small company run by a father and daughter tandem. Alas, the company isn't exactly successful, and money is needed desperately. Thus, Aika accepts the very dangerous job of acquiring an artifact called Lagu for a hefty sum. The boss's daughter Aida Rion joins Aika on this particular mission, and the two set off.—Anthony Pereyra {[email protected]}

From the creator of Project A-Ko! She's sexy, suave and sophisticated, but she's no bimbo. She's a martial arts expert and a jet fighter pilot with the body of a supermodel. She's Aika, and she's one of the best secret agents in the business. Armed with her trusty, semi-sentient super-battle bustier, no risk is too great!—Anonymous
