Ren Mihashi is a pitcher who stubbornly clings to the mound, no matter the outcome. His middle school teammates loathed him, attributing their frequent losses to his performance and suspecting that his position as a starter was due to favoritism. Convinced he had no future in baseball, Mihashi transferred to a different high school.
Upon joining Nishiura High School, he is quickly recruited into the newly formed baseball team by individuals who see his hidden talent. Mihashi teams up with Takaya Abe, a tough catcher who commits to unlocking Mihashi's full potential as an ace pitcher, provided Mihashi always follows his orders. This marks the start of Mihashi's journey to gain the strength and confidence to stand proudly beside his new teammates on any field.
