At just 12 years old, Takumi Harada is already a baseball phenomenon. But when his family moves to the countryside town of Nitta, Takumi is forced to join a low-performing school team. Undeterred, he believes his mere presence can elevate the team's performance. However, he needs a catcher who can match his incredible pitches. That's where Gou Nagakura comes in - a fellow student, Takumi's admirer, and a strong player who's eager to catch Takumi's pitches. Though they initially struggle to work together, they eventually become a united "battery." However, Takumi's arrogant behavior causes conflict with his teammates. With guidance from his wise grandfather, he learns to balance his passion for the game with being a team player.
