Gachiakuta manga volume 7 features story and art by Kei Urana.

Rudo lives in the slums of a floating town, where the poor scrape by under the shadow of the rich who live a sumptuous life, simply casting their garbage off the side, into the abyss. Rudo was falsely accused of murder, and his wrongful conviction led to an unimaginable punishment--exile off the edge, with the rest of the trash. Down on the surface, the cast-off waste of humanity has bred vicious monsters, and if Rudo wants to have any hope of discovering the truth and seeking vengeance he will have to master a new power in this latest volume!
