Ryō Azumi (あずみ 椋 Azumi Ryō) is a Japanese manga artist whose works draw on Old Norse literature and other subjects from Northern Europe.
Azumi published her first work in 1981 and made steady contributions to Wings and other magazines in the early 80's. In 1986 she published the first part of her magnum opus, The Scarlet Sword (緋色い剣, Akai Tsurugi). The work appeared in installations up to 1993, consisting of a total of 1675 pages in 10 volumes. Akai Tsurugi takes place in the 10th century Nordic world, following both mortal heroes invented by the author and the Norse gods struggling against Ragnarök. The author attempts to situate her story naturally within the Norse literary tradition, working with such real historical themes as the social changes brought on by the conversion of the Norse peoples to Christianity. Many of Azumi's other works explore similar subjects.
More recent series by Azumi include the following.
