Atsushi Saga

Guin Saga is a best-selling heroic fantasy novel series by the Japanese author Kaoru Kurimoto, in continuous publication since 1979. A record 100 volumes were originally planned, but the current total stands at 150 volumes and 27 side-story novels, with the last twenty volumes and six side stories being published posthumously. Kurimoto was working on the 130th volume of Guin Saga up until May 23, 2009, after which point she became too ill to write and died three days later. After the 100th book in the series was published in 2005, an event to celebrate this was held in Tokyo, with 600 attending. Guin Saga is the longest single-writer's work in the world, with total sales of 30 million copies.
