Born in a different universe, Trex, a former computer operating system/artificial intelligence, woke up to find himself in a world that revolves around the energy called mana. In a late 20th century that has a European flair, Trex opens up a store similar to the early 21st century arcade that was filled with games. Remembering how his last master's wishes were before he perished, he aims to create a virtual world beyond what the reality could provide. Unfortunately for him, in a society where individuals are seen as more important than an entire city, the cultural difference made a simple wish turn into something even more.
