Hisashi Sakaguchi left school at age seventeen to start working for Osamu Tezuka's animation studios. As assistant animator, he collaborated on the productions 'Atomu Taishi', 'Jungle Tatei' and 'Princess Knight'. In 1969, he started working for himself, focusing on comics and illustration. However, Sakaguchi had to wait until 1984 for fame to come his way with the 1400-page historical story 'Fleur de Pierre'. In the 1990s, he continued with 'Version' and 'Ikkyu', an imaginary biography of a Japanese monk in the fourteenth century.
