In order to solve the mystery of 'acquired feminization', a strange disease in which a man changes into a woman's body, we interviewed a former man who was said to have developed feminization.He is the drummer in an alternative rock band called "nosnos (ex. Nostalgia's Nest)" which is active in Tokyo.He says that his physical characteristics have changed greatly since he became a woman, and he is suffering from not being able to play the drums as he expected.He palpates his legs and breasts to make sure, and has sex to test the sensitivity of his vagina.
