The story puts us in the prefecture of Saitama , where we meet Ren Mihashi, a baseball fan that comes from being in high school pitcher, the Mihoshi. Mihashi was the A's rotation in high school, but he and his colleagues believe that only won the starting job because his grandfather was the owner of the school. His teammates hated him, and always lost their games. Mihashi was totally convinced it's a lousy baseball pitcher , leading to graduate to middle school with very low self-esteem.
Later transferred to Nishiura Institute with plans to leave baseball. In Nishiura has no intention of entering the computer, which is that the years spent in high school under the gaze of hatred and threats of his companions have eroded much confidence in himself, and thinks that it would never be pitcher although present. The first opening theme of anime is "Dramatic" by Base Ball Bear and the first ending theme is "Medaka no Mita Niji" by Kozue Takada.
