The vast underground kingdom only has one goal: reach the surface. Gray, an athletically gifted student, has always relied on his strength and his obsession with reaching the "surface" to get by. As graduation approaches, a speech from the new Digforce Chieftess, in an attempt to shatter everything he thought he knew, leaves Gray feeling more confident in his beliefs than ever. With his reinforced conviction, he begins his journey to become a Digman and find the surface, unaware of the challenges that await.
