TSF-019 A 20-year-old male piano-playing YouTuber who woke up as a woman was thoroughly interviewed. He had said, I want to increase my views through my own talent, but after a sudden transformation, he switched to becoming an adult content creator. Kazuki Sawashita

To investigate the mystery of the rare condition known as acquired feminization, in which a man’s body begins to change into a woman’s, we interviewed a former man said to have developed the condition. He is a piano YouTuber, and the video he posted after the transformation apparently went viral. When asked whether he might consider promoting himself as a woman going forward, he rejected the idea, saying, I don’t want an erotic image. I want to be recognized for my piano skills. However, after discovering a new kind of pleasure, his mind gradually begins to change as well. Can he continue to uphold his pride as a pianist?
