Qingming is an internet-addicted boy. He is a genius in games and an average student in studies. Qingming has a younger sister who is very cute but a rotten girl. She often rapes her older brother. One day, her younger sister found a game full of beautiful men called "Touken Ranbu", so she introduced this game to her older brother to satisfy her fantasy, but she didn't want it to come true. Her older brother traveled hundreds of years ago and became a sword! My younger sister said that she was very easy-going, but she was a little worried about how she could cover up her lies and how her brother could make a stable living in the gaming industry.
