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, but the final total stands at 130 volumes and 22 side-story novels, with the last four volumes and the twenty-second side novel published posthumously. Guin Saga is the longest continuing single-writer’s work in the world with total circulation exceeding 28 million worldwide. The story centers around a mysterious warrior named Guin, an amnesiac with a leopard mask magically affixed to his head. Remembering nothing but his fighting instincts and the word “Aurra”, he confronts a world laden with danger, intrigue, and magic.
