The Year 24 Group is a grouping of female manga artists who heavily influenced shōjo manga beginning in the 1970s. While shōjo manga of the 1950s and 1960s largely consisted of simple stories marketed towards elementary school-aged girls, works by members of the group significantly developed shōjo manga by expanding it to incorporate new genres, themes, and subject material. Narratives and art styles in shōjo manga became more complex, and works came to examine topics such as psychology, gender, politics, and sexuality. Manga produced by the Year 24 Group brought the shōjo category into what scholars have described as its "golden age".
