Aiko Miyazaki was enrolled in the graduate program at the Tokyo University of Science when she was recruited by Naikaku Jōhō Chōsashitsu (Naichō), Japan's premiere intelligence agency. Miyazaki's sharp intellect and stunning looks made her a prime candidate for secret agent status, and she was promptly placed on a research and development team consisting of Naichō's top physicists, chemists, and mechanical engineers and put to work creating new technology for the government. Although Miyazaki's team was responsible for several innovations in surveillance technology, by far their most significant invention was a cluster of artificial, miniature wormholes—tiny warps and distortions in the fabric of space-time. At Miyazaki's suggestion, the wormholes were contained within an innocuous woman's purse so they could be applied in the field without attracting undue attention. It was soon discovered that the wormholes, in conjunction with Pym Particles and cutting-edge nanotechnology, served as ideal storage devices in the field—virtually any object, no matter how large, could be stored in Miyazaki's aptly-named "Power Purse" for later use.
