Redesigning of Kaitenkou, a chinese 'naga'.
Celestial Dragons were a group of Oriental Dragons which pulled the chariots of the Chinese gods and guard their palaces. Each Celestial Dragon is given a pearl which she or he may ascend to heaven with. Without their pearls, they lose their status as Celestial Dragons and become Dilong, whom guard over mountains, rivers and streams. They are bound to Earth.
Gouhi is one such Celestial Dragon. He descended from the great Huanglong, who wrote upon gold tablets the language of the kingdom, giving man writing. But Gouhi was tossed out of the heavens for eating humans, which dragons were forbid to do. He terrorized the Chinese and Japanese coastlines along the East Sea. He was soothed from his rage by taking human sacrafices, usually female shrine maidens.
One day Gouhi came upon a small Chinese island offering a very beautiful girl. He gobbled her up, but the purity of her heart upset his stomach for ten days. At the end of the ten days, he regurgitated his partially digested meal. The girl had been half-changed, with a human torso and a long serpentine body. And she became forsaken to both humans and dragons. The only creature that loved her were the snakes of the Earth, which were also forsaken. Her name is Kaitenkou.
Because of her disconnection to dragons, she requires feeding. She preys on humans once a month, further isolating herself from them. Once every month her body secretes material that grows into an egg, and she sleeps for two days and regenerates in the egg. After every hatching her coloration and scale type changes.
