Riyoko Ikeda
In 1969, a group of women manga artists later called the "Year 24 Group" (also known as "Magnificent 24s") made their "shōjo" manga debut (year 24 comes from the Japanese name for 1949, when many of these artists were born). The group included Hagio Moto, Riyoko Ikeda, Yumiko Ōshima, Keiko Takemiya, and Ryoko Yamagishi and they marked the first major entry of women artists into manga. Thereafter, "shōjo" manga would be drawn primarily by women artists for an audience of girls and young women.
