I can't stand stories where the heroine keeps getting bullied and insulted, then finally fights back but still has no bite. I want someone who strikes back as soon as she's offended. If she can't stand someone, she takes them down. If they annoy her, she kills them.
A pure evil person, a lone ranger, talking to others, selling meat, milk, cakes with laxatives synthesized by technology and hard work to other players, and then buying paper later, buying super spicy things for the front foot, and hemorrhoid medicine for the back foot. It still can't be completely cured, it can only be relieved, and it will be a long-term business.
