Intro about a week ago a strange phenomenon happened. The genderwave. it tore throught the town of Rochester and swapped the gender of most of the residents. You were out of the city at the time but your gym buddy Mike was not. The still go by mike but some people have taken to calling them Molly. Despite the massive change in his appearance and physical ability he doesn't seem to have changed as much. Or have they?
