Renge Miyauchi attends Asahigaoka Branch School, starting as a first-grader and progressing to second grade by the third season's end, then third grade in "Non Non Biyori: Remember," placing her between ages 6-9. She lives in a rural village with minimal modern amenities. Her parents are often busy with farm work and have little on-screen presence. Her older sisters are Kazuho Miyauchi, the local teacher, and Hikage Miyauchi, a Tokyo high school student. Renge's grandmother gifted her school backpack, though their direct interactions remain unseen. She possesses lavender hair usually in twin pigtails tied with yellow ribbons, a gift from Kaede Kagayama during her infancy. Her reddish-brown eyes are consistently half-open, a trait shared only with Hikage. She stands 117 cm tall and frequently wears ribbons in her hair or on clothing, including a pink ribbon on her swimsuit. In "Remember," her hairstyle changes to a single ponytail resembling Kaede's youth. Renge blends curiosity, eccentricity, and perceptiveness beyond her years. She invents unique names, composes original songs played on her recorder, and appends the local dialect suffix "-non" to sentences. Academically proficient, she excels in art, winning a children's drawing contest with a portrait of Komari Koshigaya, and independently grasped multiplication by extending addition concepts suggested by Konomi Fujimiya. She shows affection towards friends and family but sometimes reacts warily to Suguru Koshigaya's eccentricity, occasionally fleeing him. Her demeanor matures over time, notably in "Nonstop" and "Remember." Her skills include artistic talent, recorder proficiency (using an instrument from Kazuho), and whistling techniques to summon her pet tanuki "Gu." She prepares food for Gu and previously cared for a tadpole shrimp named "Hirataira-san" (Flatty-san). Her signature greeting "Nyanpasu" merges "nyan" (cat sound) and "ohayō gozaimasu" (good morning). Key relationships shape her: * Kaede Kagayama ("Dagashiya"): Initially paid to babysit, Kaede became a mother figure, nurturing Renge's artistic passion with crayons. Their bond deepened into a quasi-sibling dynamic. * Natsumi Koshigaya: Her primary playmate, who originated the nickname "Ren-chon." Their friendship began when a young Natsumi, initially jealous of attention diverted to Renge, was encouraged to play with her. * Honoka Ishikawa: Her best friend, met during summer visits to Honoka's grandmother. Their abrupt separation distressed Renge, but winter reunions and exchanged gifts (candy for a cat brooch) solidified their bond. * Younger Children: In "Remember," Renge mentors Kasumi, promising to be a reliable senpai, and comforts Shiori during her mother's labor pains, acting as an older sister figure. Her development involves navigating transient friendships, embracing mentorship roles, and expressing aspirations like becoming a teacher like Kazuho. Her family owns a mountain. Her favorite things include rabbits and curry. She smiled only twice in the first season.
