Shimeru Futana

Futaba's older sister Shimeru Futana is a college student at Komatane College with the same gender-switching trait as Futaba and her father . When she changes gender, she becomes a tall, blond lady-killer. She has embraced her change much more fervently than Futaba. Futana is a major pervert playboy and likes to take every opportunity she can to grab Futaba's breasts - or anyone else's, for that matter. Her bedroom is wallpapered with girlie posters and centerfolds.
