Honma Kusuko has dreamed of reaching Koshien since childhood. Because girls are barred from playing in high school baseball matches, she resolved to get there as a manager. One day, she discovers the baseball club's sole two members and declares that she will recruit five new members as manager to prevent the team from being disbanded. The fact that these five recruits happen to be animals is no obstacle for the woman who would go on to become Japan's number one baseball manager.
