An epic fantasy adventure set in an alternate medieval Japan, where humans co-exist with the mythic half man/half horse beasts known as centaurs, or "jinba". The centaur race were long revered as deities in ancient times; however, with the advent of the sengoku (warring states) period, humans started to enslave and use them for military purposes due to their speed, stamina, and ability to communicate in human language. Centaurs living in the plains were rapidly subjugated; in contrast, large numbers of centaurs living deep in the mountains were still free due to their relative isolation.

A wild and proud samurai jinba from the mountains named Matsukaze, known as the redheaded rock tiger, is caught while protecting his son. He is traded to a feudal lord, and taken to his land. There he meets another centaur, named Kohibari, whose village was burned down as a child. He is a tame centaur, who had his arms amputated when he was captured, and has given up hope of escaping his human captors. If they can get over their differences and work together, they just might be able to return to the wilds as free centaurs.
