Aizawa Mashiro, the 'deaf' pitcher, and Nonaka Hiroaki, the 'hearing' catcher.
A coming-of-age story about a high school battery that bridges the world of silence and the world of sound!
At the entrance ceremony, Mashiro takes the stage as the school's first-ever 'integration student', introducing himself in sign language. Hiroaki shrugs it off, thinking it has nothing to do with him. Baseball's all he cares about, and he just stuff the sign language chart they handed out into his pocket.
But after school, Mashiro showed up in front of Nonaka again at the baseball club hoping to join the team as a pitcher. Forced to form a battery with him, Nonaka thought, 'A guy like him's nothing but a dead weight.'
However, when he caught the ball Mashiro threw straight at him, the words that came out of Nonaka's mouth was 'Nice ball...'
That was the moment their story began.
