When they were kids, big sister and big brother used to beg on the street. Big brother was always very strong-willed towards strangers. One day, when they were ten years old, they were adopted by a benefactor. The benefactor took in a young man who was already a great swordsman. Big sister fell for him, but didn't tell him because she was afraid that he would kill her. When she saw him again, she and the young man started a relationship. The young man saw that big sister was the only person he loved. He also said that during his life, he loved the daughter of the benefactor. Mr. Hell envoy apologizes to the two of them for their actions. He says that he'll try to dissuade big sister from doing foolish things.
