Despised by his middle school team, Ren Mihashi's unwavering presence on the pitcher's mound was blamed for their persistent defeats, with the starting position deemed a result of bias. Disillusioned, Mihashi fled to a different high school, resigned to his fate as a baseball failure.
Yet, upon his enrollment at Nishiura High School, Mihashi finds himself unexpectedly welcomed onto an ambitious, fledgling baseball team, whose members recognize his untapped talents. There, he forms a formidable bond with the stern catcher, Takaya Abe, who vows to unlock Mihashi's full potential and mold him into a dominant pitcher—as long as Mihashi unflinchingly follows Abe's every command.
Thus begins Mihashi's journey towards building the resilience and conviction necessary to stand shoulder-to-shoulder with his new teammates, ready to face any challenges head-on.
