12 Beast manga volume 5 features story and art by Okayado.

Eita’s got a plan for taking out the invading army and their gigas–but that plan doesn’t take into account the Divine General Vajra the Dog, or its driver, the sharp-shooting Hunter. When Hunter’s counterstrike causes an ice wall to collapse, trapping Eita alone in a cave with the “lone wolf” Freki, things start to heat up… and the two of them discover an unexpected ally. The hunter becomes the hunted in Volume 5 of this monstrous fantasy adventure!
