Kaoru Kurimoto's 130-volume epic fantasy novel series Guin Saga is a landmark in Japanese pop culture. Specifically, it was a key influence on works like Kentaro Miura's Berserk. More generally, in the early '80s, author Kaoru Kurimoto, along with Vampire Hunter D's Hideyuki Kikuchi, helped shape the template for light novels. A lot of the pacing and world building that helped define the medium come from those fantasy works.
Now, its 2009 anime adaptation is streaming on Crunchyroll. Atsushi Wakabayashi directs the Satelight (Macross F) work, with music by Final Fantasy's Nobuo Uematsu.
Currently episodes 1-4 of the 26-episode series can be viewed by all visitors. The rest are currently available to premium subscribers. Regional restrictions apply.
From Crunchyroll's description:
On the run from an army that destroyed their kingdom, the twin heirs to the Parros throne must avoid a magical land filled with incredible dangers. They are surrounded on all sides-by warring armies, an apelike tribe of desert creatures called the Sem, and the ruthless Langon clan. Giant sandworms, glowing, malevolent creatures, and powerful wizards mastering in the dark arts threaten them at every turn. If they were alone, they would surely perish. But in a dark forest, they are discovered by a mysterious stranger, a powerful warrior wearing a cursed leopard mask he cannot remove. His name is Guin. He becomes their protector and companion, though he remembers nothing of his life before meeting these young runaways. Together, they begin a treacherous quest to find safety for the royal twins-and the answers to Guin's secret origins. Based on the bestselling novels, this magical, animated epic is now available in one complete, sweeping set!
The first five volumes of the prose series and one of its manga spin-offs have been released in North America by Vertical Inc.
