Akari is a 17-year-old genius hacker who styles herself as a magical girl of sorts. She is Nishikubo and Yomatsuri's daughter, and claims she dedicated herself to hacking while her parents were not with her due to work. She has allegedly hacked into international satellites even from the US. She operates under the handle "Code Papillon" when hacking. Akari is so skilled at computers, she has the ability to access and control every weapon of mass destruction on the planet, but she claims she can only attempt this once, as the world's governments would recognize and counter future attempts.
