High-school student Ikkyū Sanada knows nothing about baseball, but his talents are recognized by the manager of the baseball club, and he takes up the sport. While his ignorance of the game leads him to make many mistakes, Ikkyū—who is in fact a descendant of ninja—displays superhuman abilities and leads the team to the High School Baseball Championships.
