Cao cao's origins, courtesy of @bennialover on the dx.4 discussion thread on forums.animesuki.com.

He was born in a rural village in the mountains of China and was the son of two very common farmers, not knowing they are descendants of Cao Cao. He awakened his Sacred Gear and because he was about to be sold away to an organisation that wanted a god destroyer by his parents whose eyes were dazzling [no doubt for money], he ran away from home. He was pursued and fought off his pursuers until he eventually returned home to learn his parents had committed suicide due to a large debt. After asking himself whether he had caused his parents to die due to mistake in his choice, he began to think about how much he could challenge the power as a weak human being, and started gathering people with similar circumstances to him to form the Hero Faction.
