Guin Saga (グイン・サーガ) 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,[4] 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.[5] 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.[6] After the 100th book in the series was published in 2005, an event to celebrate this was held in Tokyo, with 600 attending.[7] Guin Saga is the longest single-writer's work in the world,[8] with total sales of 30million copies.[5]
