Z/X: Ignition

Z/X: Ignition takes place in the near future, where five "Black Points" have emerged globally, serving as portals to parallel worlds. These portals allow creatures from five different worlds, each existing in different timeframes, to invade Earth. Each of the five invasion forces fights to eliminate the other future timeframes, with the goal of securing their respective worlds' survival. The key to this conflict lies in a card-shaped device.
