Guin Saga

Guin Saga (グイン・サーガ, Guin Sāga) 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 149 volumes and 27 side-story novels, with the last nineteen volumes and five 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.

The main story of Guin Saga resumed on November 8, 2013, four years after the passing of the original author. Yū Godai published Volume 131 Parro no Ankoku on that date, followed by Yume Yohino's Volume 132 Cylon no Banka in December 2013.
