Jinzan

"Your sister is kind."

Knowing that "god" had disappeared, a foreign demon came down to Earth to take his place. He gains powers by killing other demons. He has a high self-esteem and is very arrogant. He's set his sights on Mashiro and plans to acquire her.

He looks at youkai like domestic animals. Even his younger brother, Hakushin, is nothing more than a useful tool in his eyes.
