Ookiku Furikabutte. Ren Mihashi was the ace of the baseball team in his middle school but they could never win because of his poor pitching. Constant defeats inevitably result in his teammates bullying him and reaching the point that his teammates were no longer striving to compete, leading Mihashi to graduate with little self-esteem. As a result, Mihashi wants to go to a high school in another prefecture where he has no plans to play baseball. Unfortunately he is pulled into joining their new team as the starting pitcher upon his arrival at Nishiura High.
While at first reluctant, Mihashi discovers that this is a place where he will be embraced for who he is; he begins to have more faith in his own abilities with the aid of the catcher Takaya Abe. Abe, seeing Mihashi 's talent, makes it a priority to help him become a pitcher worthy to be called an ace.
