Murasaki Kageyama

A Kraken, or giant octopus, is the king of the dark sea beasts. It resides in the depths of the ocean. It's somewhat playful but maintains its honor and that of its master.

A giant black wolf, the king of the dark beasts on land. It resides in a dense forest, making it impossible for light to penetrate. Its nature adapts to its master's changing personality.

A giant black crow, the king of the dark beasts in the sky. She constantly herds the dark clouds to prevent sunlight from penetrating them, causing storms. She is a woman of elegant and graceful nature.

A dragon who has lived for centuries, he was always chosen to be the companion of the highest king of the dark side of the earth because he was the strongest beast among the other dark beasts. His nature is friendly despite his frightening appearance and must fight against the light side of the earth. And now he was chosen to be the companion of Murasaki Kageyama who is cold and insensitive. He always reminds her but still like that.

Cold and insensitive, he's always oblivious to what he says. For example, when he met the dark king of the forest, whose king was a woman, he told her she was beautiful, without any expression. The woman blushed slightly at his words.
