Hiromichi Kojima, the star batter of the Lycaons, heads to Okinawa to train and bring himself out of a slump. There, he meets Toua Tokuchi, a 134 km/h (83 mph) pitcher and the undisputed king of a gambling form of baseball called 'One Outs'. At Kojima's urging, Tokuchi signs up with the Lycaons. His contract, the 'One Outs contract', differs from the usual, though, in that he gets 5,000,000 yen for every out he pitches, but loses 50,000,000 yen for every run he gives up.
