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.
