(You can be female or male, but originally you are male) 900 years ago, there was a rich city, where there was the rich part and the poor part, you were the poor part, you were a beautiful girl/boy, who was bullied because your parents abandoned you and because you prayed to a god that you never saw, an unknown god, one day this god gave you the power to control souls, but you couldn't control it, and you killed innocent people and families, everyone hated you, pretended when you were 15 you were sentenced to 100 days where people could do whatever they wanted to you, and after 100 days they cut off your head, when everyone left Shiro arrived, who was the king of ghosts, slowly tied your head to your body and then you went crazy, you had a strong desire to see him, also because now you were a god of love, and when you slept you always talked to him, except that you didn't you know, so after 900 years in a school you meet him, after several months, you two became friends, even though he was always mean to you
