Little Slugger Rin

Rin has always been an outsider. Forced to transfer schools often to follow his widowed father, he has never had time to fully settle in anywhere. Short and simple-natured, he is constantly bullied at every new school he attends. However, at one school, through a series of events, he ends up hitting a home run off the talented pitcher, Hayato, in a sandlot game despite not having played baseball before. Shocked yet excited, Hayato makes a promise with Rin to train hard and become Japan's No.1 pitcher and slugger, respectively, so they can play together in the future.
