Aika Zero  

아이카 제로, AIKa: ZERO

Let me rephrase your statement for you. In the latest chapter of Aika's story, she is now 19 years old, which is three years older than her age in R-16 and seven years younger than in Agent AIKa. There have been some strange occurrences at a girl's school recently. The most attractive girls are joining an exclusive club without any singing involved. Instead, they are being abducted by a mysterious entity that takes control over them through indecent means. By chance, Aika was flying overhead during one of these abductions and was attacked to prevent her from getting closer. Despite the danger, she is intrigued about the source of these attacks. Fortunately, her former partners from R-16 have decided to investigate these incidents, which adds more action and panty flashing to Aika's series.
