A city XXX years in the future
The era is Year XXX, where AI has achieved every possible evolution. Seeking even greater convenience and technology than AI, humanity created the HOLO Project to develop HOLO, a system that connects the human nervous system to the city's network. After decades of research and experimentation, they finally completed a special artificial computational core: the HOLO CORE. By attaching special equipment, it became possible to connect a HOLO suited to each individual's body. And thus, NEXUS CITY became a rapidly developing future metropolis centered around the HOLO CORE. As a world-class megacity, not only do trains fly through the air, but everything has been transformed into neon.
