In order to prevent sexual crimes, which are on the rise in the year 20XX, the government has introduced the revolutionary "TSF Prison Policy" to rehabilitate violent sex offenders by forcibly changing their bodies into the opposite sex. If they hone their femininity and become model prisoners, they will be sent to the women's cell, but if they do anything lewd, they will be sent to the men's cell as punishment! Is life imprisonment with a body of the opposite sex heaven or hell?
