Toua Tokuchi is an athlete by profession, but a reckless gambler at heart. On the streets of Okinawa, he uses nothing but his wits and a "fastball" peaking at a mere 134 kmph to somehow achieve 499 wins in the game of "One Outs," a simplified version of baseball between the pitcher and one batter. Amazed by Toua's unique prowess on the mound, veteran slugger Kojima Hiromichi artfully scouts the pitcher for his long unsuccessful team, the Saikyou Saitama Lycaons. Kojima desperately hopes Toua will lead them to the championship; however, Tsuneo Saikawa, the mercenary owner of the Lycaons, sees the vastly talented pitcher as a threat to the income generated by the team. Rising to the challenge of swaying the owner, Toua suggests a one-of-a-kind "One Outs" contract: every out Toua pitches will earn him five million yen, but with every run he gives up, he will lose fifty million yen.
Adapted from the manga by Shinobu Kaitani of Liar Game fame, One Outs documents the intense psychological battles between Toua and those around him. With millions of yen at stake, can a pitcher who has done nothing but gamble in a head-to-head imitation of baseball finally lead a real baseball team to victory?
