AIKa Zero

At 19 years old, Aika finds herself embroiled in a series of mysterious events at a girls' academy where an alarming trend has emerged. Beautiful and charismatic students are vanishing, seemingly drawn into an internal club that operates under the influence of an enigmatic force. Rather than a simple sign-up process, these girls are being abducted through questionable means, leaving the academy shrouded in intrigue and danger.

While on a routine flight, Aika witnesses one of these unsettling abductions and becomes determined to uncover the truth behind the attacks. Intrigued by the threat rather than deterred, she teams up with her former partners from R-16 to delve deeper into the mystery. As the investigation unfolds, Aika navigates a world filled with action, humor, and the signature elements of her adventures, all while confronting the unusual challenges that lie ahead.
