Riyoko Ikeda
In 1969 a group of female 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 the year 1949, the birth-year of many of these artists). The group included Moto Hagio, Riyoko Ikeda, Yumiko Ōshima, Keiko Takemiya, and Ryoko Yamagishi. Thereafter, primarily female manga artists would draw "shōjo" for a readership of girls and young women. In the following decades (1975–present), "shōjo" manga continued to develop stylistically while simultaneously evolving different but overlapping subgenres. Major subgenres include romance, superheroines, and "Ladies Comics" (in Japanese, "redisu" , "redikomi" , and "josei" ).
