Rumiko Takahashi
She made popular manga books such as Ranma ½ and InuYasha. She is the richest woman in Japan and her manga is loved all over the world.  She joined Gekiga Sonjuku college: a manga school run by Kazuo Koike, also a manga artist. With the school's help, she managed to make a "doujinshi" (self-published work mostly for beginners) manga artwork, for example, Bye-Bye Road and Star of Futile Dust.
