What's Inside the Egg?

The eldest prince of Senyu finds an egg. Curious, he decides to hatch it. The eldest prince of Senyu hatches a little beauty. The little beauty isn't human, but a dragon, one that can never get enough to eat. To raise this dragon, the eldest prince of Senyu becomes the biggest glutton in Senyu, also known as the Bottomless Pit. The little beauty has no gender before adulthood. There is a juvenile beast phase, as well as a humanoid phase. At some point, the eldest prince of Senyu finds himself with a son who looks a lot like him: an illegitimate child (though he refuses to admit it). When the little beauty grows up, the first thing it does is bite the eldest prince of Senyu's primordial spirit beast, wanting to see whose teeth will break first, its own or the Black Tortoise's shell. That's because the Three-Headed Cloud Serpent said it was a matter of pride.
