Aika R-16: Virgin Mission (stylized AIKa R-16:VIRGIN MISSION) is a three-episode anime OVA series by Studio Fantasia, developed as a prequel to the Agent Aika OVA series and released on the tenth anniversary of the series. It takes place ten years before Agent Aika and follows the story of Aika's first mission when she is 16 years old. The series was followed by a three-episode OVA sequel called Aika Zero where she is 19 years old. As with its predecessor, both series are known for their abundance of fan service in the form of panty shots. They were acquired by Bandai Entertainment who dubbed the first series in English and licensed the second series with English subtitles.[1]


The mini-series follows 16-year-old Aika Sumeragi, who recently got her C-class license to be a salvager, a person who searches for treasure among the ruins of the Earth's cities which have been submerged following worldwide earthquakes. However, at high school, she is regularly late for class and then her posters advertising her salvaging services are taken down. However, one afternoon, she is invited by Eri Shinkai, the class president, to join her Treasure Hunting Club where they look for the coordinates hidden away in a tattoo on classmate Karen Minamino. Aika gladly accepts, but during the trip some of her schoolmates and even their club advisor attack them in an effort to try to capture Karen. Aika defeats the girls and discovers they are being controlled by some devices implanted in their bodies. As they approach the destination, Karen starts acting strangely as if she remembers being there before. At the underwater base, Aika, Eri, and Karen make their way to a locked lab, and discover Karen's true identity.

In Aika Zero, 19-year-old Aika Sumeragi is called to investigate the goings on at a private Catholic school that is run by a council group called the White Knights. In the school, the students have been mysteriously disappearing and those who have returned have no memory of the event. They discover that there are aliens who use rope-like tendrils to probe the girls, knocking them out and harvesting their energy, or possessing them to do their bidding.
