At the outset of the manga the team is in trouble, as there are not enough players to play a game. Additionally, the coach has left after a conflict with Fujiwara. However, Aikawa transfers to Mizuho and through his enthusiasm and sheer love of the game, infuses the few remaining members with a sense of purpose.
Despite the fact that there are only five of them (i.e., they have no substitutes), they manage to get the coach of the girls' team to coach them as well. At first, she seems very strict, but later reveals her attachment to her "Dear Boys". Together, they do their best to make their dreams come true.
