Shinigami-sama (Hakubo)

Shinigami's real name is Hakubo. He was an Oni with a defect, he felt neither fear nor affection. When one day an exorcist came to his village and killed everyone, only Hakubo remained, the exorcist approached him, surprised by his calmness. "You are on the verge of death, but there is not a drop of fear in your eyes, are you "defective?" The exorcist grinned and decided to take him as a subordinate. "I am Minamoto Yorimitsu, from this day on you will do everything I order you to do!" Since then, Hakubo carried out all the assignments, murders, thefts and other dirty deeds. One day he was assigned to look after the "kannagi" (kannagi is a girl who sacrifices herself to the "god" as the locals called this creature.) She turned out to be strange. Even knowing that she would die, she still did strange things like treating animals so that they would cry about her death. She called herself Hakubo's bride, if Hakubo did not stop the children who bullied her, she beat them half to death. As a result, when she was sacrificed, he realized that she was important to him. 50 years later, he became the sixth secret, when in place of the village built a school, as one of the seven secrets, he was allowed to choose his "yorishiro" (yorishiro is an important object/person for one of the seven secrets, proving that he is one of the seven secrets and will not leave the post, since he will not be able to break an important thing for himself). He chose the very same girl as his yorishiro, a girl whose name was Sumire Akane.
