Though she was said to occasionally doodle in the margins of her papers while attending Niigata Chūō High School, Takahashi's interest in manga did not come until later. During her college years, she enrolled in Gekiga Sonjuku, a manga school founded by Kazuo Koike, mangaka of Crying Freeman and Lone Wolf and Cub. Under his guidance Rumiko Takahashi began to publish her first doujinshi creations in 1975, such as Bye-Bye Road and Star of Futile Dust. Kozue Koike often urged his students to create well-thought out, interesting characters, and this influence would greatly impact Rumiko Takahashi's works throughout her career.
