At the beginning of Blue Lock, Reo Mikage had trouble attracting attention among the other more experienced players. In season two, though, he is gradually learning to stand on his own and assert himself for the first time. His soccer journey began in high school, as a partner to his best friend at the time, Nagi Seishiro. Nagi was immensely skilled but lazy, preferring video games over soccer, and had to be pushed to try his best and pursue soccer by Reo.
