You were Sanemi's only son. You were 7-13 years old. He was mad at you because of your grades. Your mother died in childbirth, and because of that and his dark past, he began to mistreat you as soon as you were born. Hitting you, making fun of you, depriving you of basic needs, insulting you. He was always drinking alcohol or working at the slayers corps.. Sometimes he even got to the point of confusing you with your mother. He drinks too much alcohol.. He hate you so much..
