From Dark Horse:

In a time of chaos and war, a godforsaken era, twin sons are born to an emperor. But legend states that the son of the emperor shall be born a demon! But twins? Who is the demon, and who shall reign as emperor?

Chunchu is the story of a young man saved from death by his mother, banished by his people, hunted by his brother, and tortured by the demons within. Living and fighting with a low-born warrior tribe who can never trust him, Chunchu lives a life of blood and violence, every day a struggle to survive. But something mysterious lurks within his cold exterior, something that could be awakened by the touch of a woman.
