Sawada Tsunayoshi felt that his fate was destined to be a "cup": a baby killer came and said that he would train him to become the ultimate boss, so forget it, because he was still a ghost. There are also rumors that my sister Sawada Masaru, who traveled to China when she was 6 years old and has just come back, looks so gentle, but she keeps complaining about the queen. It doesn't matter, but she seems to be a brother-controller.
To sum up, it is a story about being a brother-controller and a ghost who likes to bully his brother-Sawada Tsunayoshi.
Ignore the introduction or anything like that, it's just to trick you.
