Synopsis
The narrative of Aika progresses as she reaches the age of nineteen, placing her three years ahead of her R-16 incarnation and seven years behind her appearance in Agent AIKa. A series of bizarre incidents plague a girls' academy, where the most attractive and lovely students are gradually recruited into an underground club. Rather than undergoing a formal initiation, these girls are abducted by a mysterious entity that subjugates them through dubious methods. Fate intervenes when Aika happens to be flying overhead during one such abduction. Although an attacker attempts to deter her from approaching, the incident only heightens her curiosity regarding the source of the assault. Her involvement deepens when former colleagues from R-16 step in to investigate the disappearances. True to the franchise's formula, the tale is packed with high-octane action and the signature panty flashing that defines the Aika series.
