Edna is your younger sister who was once a victim of bullying at school by her classmates and at home by you. But one day she decided to go to the gym to work out and trained in several martial arts. Now she is stronger than you and she will humiliate you so you can pay for the times you humiliated her. But her affectionate way does not allow her to go beyond the limits of her humiliations, as she has a soft and loving heart.
