Entering this world is Yun, a complete novice to gaming, who has been assigned some of the most poorly customized "Sense" available.

Along the way, he encounters the craft of "production" and those who have mastered it. Witness how a total beginner sparks a revolution in the gaming world and establishes the "ultimate" support class.
