Bokura ni wa Bokura no Kotoba ga Aru

Mashiro Aizawa, a deaf pitcher, and Hiroaki Nonaka, a 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 stuffs the sign language chart they handed out into his pocket. But after school, Mashiro appears 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 thinks, "A guy like him's nothing but a dead weight." However, when he catches the ball Mashiro has thrown straight at him, the words that come out of Nonaka's mouth were "Nice ball..." That was the moment their story begins.
