Shigeno Daigo is a grade schooler who's father is a professional baseball player.
Being enamored with his father Goro, who once even played in the Major League, Daigo joins the "Mifune Dolphins" baseball team.
However, with the pressure of measuring up to his father, he can't improve enough and quits after less than a year and turns to an uninspired lifestyle.
Then, in the spring of 6th grade, a transfer student from the United States arrives.
