The series began this past summer from HJ Bunko with two volumes out there so far.
The J-Novel Club group has picked up another novel series to work with as they’ve acquired the rights to The Underdog of the Eight Greater Tribes, which is known as Hachidai Shuzoku no Saijaku Kettōsha.
Plot Concept: Long ago, there was much war and bloodshed among the eight tribes of the world.
