Players assume the role of either Takumi Aiba or Ami Aiba , male and female Japanese amateur hackers. They receive a device called a Digimon Capture from a mysterious stranger in a chat room which allows them to capture and befriend Digimon, creatures who inhabit a next-generation version of the internet called Cyberspace Eden which users can physically enter. After traveling to the lowest levels of Eden, they are attacked by a data-based entity called an "Eater" who leaves their bodies half-digitized, and find that they can now freely travel between the real world and the virtual world via terminals. They are approached by a woman named Kyoko Kuremi, head of the Kuremi Detective Agency, who recruits them as part of their cyber division.
