Digimon Story: Cyber Sleuth

Digimon Story: Cyber Sleuth is what happens when you take Digimon and its "digital world" to its natural Cyberpunk conclusion.

In a world where Kamishiro Enterprise's virtual reality social network "EDEN" connects everything, an Ordinary High School Student is lurking in a private chatroom when a hacker impersonating Kamishiro's mascot Mr. Navit breaks in. He threatens to hack anyone who does not go to Kawloon, the deprecated past incarnation of EDEN, at the time he requests. Most of the chatters blow off the threat as a joke but three users, Nokia, Arata and the main character (default name: Takumi/Ami Aiba), decide to go through with it.

When the tiro meet in Kawloon, a Digimon program installs itself to their rigs and they are trapped inside. Nokia and Arata manage to escape to escape but at the last second the protagonist is devoured by the tentacle beast (latter called an "Eater") chasing them. Instead of dieing he/she awakens in the real world as an untextured digital construct. With the help of Private Detective Kyoko Kuremi the newly disembodied hero, now with the ability to travel through computers, delves into the seedy underbelly of Kamishiro.
