Rakuen Tsuihou: Expelled from Paradise

Angela, a girl in her twenties, was raised in a Matrix-like computer system on a space station orbiting a post-apocalyptic Earth. But after a hacker from the devastated planet below breaks into the system, she is tasked with finding and stopping the hacker in the real world. To do this, she is transferred into a clone body, given a mech, and told to meet up with an agent living on Earth named Dingo. Thus begins her fish-out-of-water tale as she not only finds herself in a strange land she knows nothing about but also has to deal with a life trapped in a body that, unlike her digital one, requires food and rest. Together, Dingo and Angela travel across the frontier-like ruined Earth, trying to solve the mystery of the hacker's identity and his true goals.
