Nagi is an unnaturally talented soccer player with amazing reflexes, good speed, and jumping skills who at his core is a very lazy and unmotivated person. As long as Nagi can get a good job and keep living a lax life he is fine with doing anything, he never had much of a drive. Before having gotten into soccer he would spend his free times at school playing on his phone before becoming best friend with Reo Mikage after seeing his impressive talents. Nagi appears to be a calm teenager.
