But it is the feeble team in the Japanese baseball championship. Fantasizing of leading the Lycaons to win the league, and in terrible need of a substitution for their wounded pitcher during a training camp, Kojima includes himself in a game of One Outs, only to lose to a standard fastball from the apparently invincible Tokuchi.
Enthralled by his skill, Kojima hires Tokuchi to the team after barely avoiding defeat in a rematch, thinking he might just be their answer to victory. Nevertheless, the insatiable owner of the Lycaons declines to give him a decent salary, leading Tokuchi to suggest an unusual contract. Every out he pitches will get him fifty lakh yen, but every run he gives up will lose him fifty million yen. With his fate now tied to that of the team, Tokuchi’s fight to bring the Lycaons to victory becomes yet another gamble—the very thing that he does best.
