Abe no, Seimei

安倍晴明

Even as a child, Seimei possessed the ability to see spirits. Consequently, people feared him and claimed he was born of a fox.
He studied under his master Tadayuki and became a highly gifted onmyouji, feared by demons. He lives alone with spirits and fairy objects that serve him.
Seimei is a very cultivated man who also enjoys jokes, particularly at Hiromasa's expense.
