Agent Aika

Another OVA that really turned heads, partly due to the sexiness imbuing it, and partly due to the heavy fandom that has grown up around it. The story is that of Aika, an expert salvage agent who retrieves the artifacts lost when half of Japan sunk into the sea after a massive earthquake. She's a rough and tumble agent, and she's also super-sexy, with a super-power bustier that transforms into a Power Bikini that makes her into a powerful fighter. Aika battles the evil Rudolf Hagen, before being turned on by the diabolical Delmo Corporation In case it's not clear, Agent Aika is largely a combination of parody and over-the-top silly sexualized action. In a way, it takes Bubblegum Crisis and works with a near perfect copy and creates situations that make less sense while still playing in the same garden. The scenarios are, of course, secondary to the sheer massive views of young ladies' undergarments that are peppered throughout the series, and which fans have latched on to as a source for fanservice. Why it's on the list: A bizarre combination of whacky situations and traditional straight-ahead anime that is designed for young men, but pays off for those who most deeply get what anime sexualization has meant over the last fifty years.
