You're assuming the gods are interested in such a thing when they aren't. [Homura grins wryly as he drops his hand down.] The gods take much less interest in the course of mortal affairs than mortals themselves would care to believe. So long as there is no threat to the Heavens, nor disruption to the balance of the world, the gods remain separate.

What makes sense to them is to contain what they fear, and cannot control. Heretical beings are born with great power, you see, and are typically far stronger than the average god. Our existence threatens their ambitions, and so we must be contained, at a minimum. But the laws of the Heavens forbid killing, so the gods cannot destroy us directly.

Instead they attack our wills. In my case, I was placed in a prison cell immediately after birth. My existence was particularly troublesome, because my mother was kin to the Jade Emperor, who rules the Heavens.
