Sawamura Eijun had just turned 22 years old; it's been six years since he left Seidou and went to play baseball for the Yomiuri Giants and became their Ace. When he had just finished a match against their rival team, the Saitama Seibu Lions, a girl almost got hit by car right in front of the stadium, but Eijun acted quickly. Just as the car made contact with his body, darkness consumed his vision, and when he woke up, he returned to the end of his second year in Seidou...again.
