Centaurs manga volume 4 features story and art by Ryo Sumiyoshi.

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 was long revered in ancient times; however, with the advent of the 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.

Now, after a long struggle, centaurs and humans tentatively coexist once more. Tanikaze is assured of his place in the world. He knows why he is here. Gonta, on the other hand, toils in search of the right path for his life. The two have an extremely strong bond, but will they be able to preserve this bond as they struggle with their seemingly diverging futures?
