I've clicked through the whole thing, and unless one of those characters was previously a man, I can't find the gender bender anywhere :p

im not positive but i think the girl from image 1716 to 1765 is the gender bender as the other girls are depicted as straight until that point

like chaoswake said 1716 to 1765 is the main character turned into a girl.
he wakes up as a girl same as imouto/ane jiru as for the "bad end" route
> Haiyami
yes it is the main character is a boy... play the game you will see that he got turned into a girl due a sickness when you go to the fail route (when you choose none of the girls and just sleep until the time runs out)

that's not gender bender. that would have a yuri tag not a gender bender.
