Rentarou Kurahashi

Rentarou is the younger brother of Riko Kurahashi. Despite being only a sixth grader, he possesses striking good looks and a level of maturity well beyond his years. Unlike his sister, whose love life is perpetually in shambles, Rentarou is effortlessly adored by girls his age—an attention he finds more burdensome than flattering. He frequently teases Riko with sharp remarks about her lack of feminine charm. Having grown up watching his sister's romantic misadventures, he had long since given up on idealizing women—until a chance encounter with Natsuo Maki left him completely smitten, revealing the sincere and tender heart beneath his cynical façade.
