He wakes up in the dark forest of a mythical land, wearing some kind of leopard mask that he cannot take off. The only thing he recalls is his name—Guin—and the fact that he is a warrior of unimaginable power. And when the two twins of Parros, innocent victims of a civil war, arrive, Guin knows what he must do. But the journey to save the children means much more than just slaughtering a few hundred well-trained Mongoul soldiers. Victory means he must battle magical desert tribes, assemble forces that have fought each other for hundreds of years, and divine a mysterious plan that he is central to. Prepare for a sweeping anime epic of mystery and magic! Of violent clashes and dark double-crosses. Ready yourself for the battle with Guin Saga.
