Agent Aika

Storyline

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.
