Koby is a teenager who has recently transferred to the New World Academy. Tired of his former upperclassman Alvida's antics, Koby is determined to make one hundred friends at his new school. It does not take long for him to meet a boy made of rubber named Monkey D. Luffy, with whom he becomes inseparable within minutes. Under the guidance of their apathetic teacher, Koby and Luffy are set for eventful lives and interactions with their eccentric classmates. During their daily adventures at the academy, they confront the seven most powerful students in the school, the Shichibukai, and defy the rules imposed by the student council, which is led by the teachers' lackey, Lucci Rob.
