Major S1

Goro is a young 5 year old boy who admires his Father. His father is one of the star pitchers for the Yokohama Blue Oceans, but when his father injures his shoulder, young Goro must decide what is more important to him- following his love of the game or following his Father's wishes

Goro disregards his father's advice and decides to continue training to become a future Pro pitcher. Meanwhile, his father is visited by his old friend and teammate, Shigeno. Shigeno says Honda's true abilities have always been in pitching and not batting, but Honda must decide on his own whether to continue baseball by focusing on hitting or find an entirely new occupation.

Goro meets and befriends another little boy named Toshiya, with whom he plays catch. During one of their sessions, they witness a Little League team in play and decide they want to become Little Leaguers. Goro's father forbids it due to the use of hard baseballs. Can Honda reach his son and show him the true reason he won't let him play before they lose their bond?

Due to her consistent care of his son, Goro, Honda begins to see Goro's nursery school teacher, Momoko Shimizu, in a romantic light. He makes the decision to propose to her after Goro advances from her school. Momoko is asked by Honda to take Goro out for his birthday, as he plans to celebrate it with him a day later.

Joe Gibson, a Major League pitcher, has come over to Japan due to a wealthy amount of money he is to receive. Honda decides he will hit a home run off of Gibson at all costs.

Honda is successful in his first bat against Gibson, so Gibson retaliates with a beanball to the head. Honda falls unconscious, but he later gets up and goes to first base as though everything is okay. That night after celebrating with his son Honda realizes something is wrong. As he tries to reach his son and give him one final farewell he falls unconscious again and dies. Goro tries to wake his dad up the next day to no success. He is diagnosed as dead at the hospital and Goro's Uncle steps in to take him. Goro runs to his nursery teacher, Shimizu, who has just revealed she was engaged to Honda. She agrees to become Goro's new mom and take care of him over his Uncle

It has been 3 years since his dad passed away, but at age 9 Goro is finally old enough to enter Little League Baseball. He returns to the field of the Mifune Dolphins, but when he arrives he learns they only have 5 players and that the team could be folding. To make things worse the soccer club has gotten permission from the city to fully take control of the field. The coach recommends Goro goes to the other Little League team in the city, but Goro is determined to play for the Dolphins and begins recruiting his classmates to play.

Sawamura decides to get rid of Goro's mitt after Komori decides to play baseball. Komori decides to confront Sawamura about it and is able to prevent the mitt from being thrown into the neighboring river. Neither realize that Goro has followed the two of them. Goro confronts Sawamura about his lack of thinking about people's feelings. After realizing Komori is indeed his own individual Sawamura goes and apologizes to him and Goro. Afterwards he asks permission to join Mifune's baseball.

Mifune begins playing the adult sandlot team in an effort to get privileges back to play on the field, but Goro's new teammates aren't sure if they should trust this arrogant rookie who has never practiced with them before.
