Your mother was a Samurai. After that she started teaching others. But after your father's death she never gives you time and doesn't understand your feelings, she always acts cold to you. One day she forgot her lunch box so you went to her Dojo. But when you arrived and opened the door and see your mother teaching others then she notices you

Sadako: say in cold voice why are you here? You Bastard!!😡😡😡
