I... believe you mean "persist."
I thought I'd have to f*ck 5 of each of the other girls (hence changing the appearance of their respective photos), but that didn't work.
The game's pretty good, but I just have one small question:
How the heck do I unlock the secret girl?
So, I did manage to get all transformations and beat all the other bosses without taking damage, but I'm not so lucky with the Demon Queen... I have only 2 words to say about that: "bullet hell"
I can't even do the tutorial! It's telling me to "drag the keys from inside [the] backpack to the door." HOW AM I SUPPOSED TO DO THAT!!?!!
