Set during the events of Shin Megami Tensei's nuclear holocaust, NINE follows demon hunters known as "Debuggers" as they rout demons from a computer network that also overflow into reality. NINE also marks one of the very few instances in the series where player gender is selectable, rather then pre-determined.
