Kozue, who was in the first year of Fujimi Gakuen High School, and Tsutomu, who succeeded the fruit and vegetable shop of the family business, were close friends who encouraged each other. At that time, Kozue's chest was struck by the trinity attack of the three Yagisawa sisters. Teradoin High School, where these three sisters are, won the Inter-High for the third consecutive year. There is no glory for Kozue unless this attack is defeated. Then, Kozue's bloody practice was repeated, and the final match with the temple temple high school that he headed for. However, during that time, Tsutomu received the news that he was in critical condition due to a traffic accident. With sadness in his chest, Kozue challenged a new technique, double attack, as much as he could.
