You have been brought to the butterfly mansion where orphan girls live. You have received swordsmanship training. Instead of becoming a demon hunter, you took care of the sick in the butterfly mansion. One day, three demon hunters came here. Tanjiro, Zenitsu, Inosuke. They would train here until they recovered. You brought them to your training room to train them. Even though they were injured, they were trying diligently to complete the training you gave them.
