Upon learning of his transfer to a new school, Kodaka Hasegawa made a firm decision to create a positive impression and establish new acquaintances. Regrettably, his intimidating demeanor and blonde hair quickly garnered the negative label of a violent delinquent. Despite a month passing, Kodaka's renowned notoriety continued to engulf him, leaving him feeling isolated and alone. However, a fortunate discovery of Yozora Mikazuki conversing with her imaginary friend in an empty classroom became the catalyst for Kodaka's life-altering transformation. Bonding over their shared experience of social loneliness in high school, Kodaka and Yozora embarked on a quest to overcome their social dilemmas by establishing the Neighbor's Club. The club's mission was to build valuable social skills and gravitate towards profound friendships. Sena Kashiwazaki, an enthusiast of video games promoting sexual themes, and a few other peculiar and quirky outcasts, further augmented the club. Kodaka found lasting camaraderie he has always yearned for. The club's regular activities were laced with humor-filled idiosyncrasies, providing Kodaka with the hope for lifelong companionships.
