Humanity is dead! Rising from the ashes, two opposing races fight for what's left of the world: Cyborgs, symbols of technological progression, and Beast Spirits, who've reverted to being one with nature. Shi Heitong, a ruthless Cyborg assassin who hates everything except sarcasm, is forced to go with an idealistic group of Beast Spirits on a quest to restore the broken world. But it's never easy to escape one's past. In the battle between machines and nature, who shall inherit the Earth? (Source: Tapas Media)
