Agent Aika (known in Japan as simply "Aika" *) is an animeOVA series which stars a Japanese woman named Aika Sumeragi (voiced by Rei Sakuma) who works as a salvager for companies that hire her, but gets caught up in a plot for world domination. This OVA series is available in North America from Central Park Media.
Plot
Tokyo has sunk into the ocean, along with most of the world, during a 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 Lagu for a hefty sum. The boss' daughter Aida Rion joins Aika on this particular mission, and the two set off. Later on, Aika and Rion are captured by Rudolf Hagen -- an effeminate but over-sexed man who wants Lagu and Aika (and just about every pretty girl) for himself. Hargen commands a huge battleship manned exclusively by droves of cute girls in mini-skirts, which should give you a hint as to how much boobs, legs, and panties you'll see along the way. Alongside Hargen is his obssessive sister Nena, who is jealous of Aika. Let's not forget the other salvager Gusto, who's also after Lagu. He's just crazy about Aika too. When Aika's special bustier is activated, she becomes a " superwoman" who can take on a whole armies by herself.
