Incase people didnt get it, in the changed Pina's ending version, a.k.a this manga,
the prison she sent to, the warden of that prison, had a son, and only son, aka the guy with feather from chapter 14,
he stole and embezzled his family's wealth as only hire to woo Pina, but Pina is scamming him. Somehow he died trying to acquire the hypnotic perfume for Pina, it is not clear how he died, its not sure either Remi did this, or (most likely its Pina's doing) tying a loose end by Pina, since he failed to acquire anything or trying to get the truth out once he realize he got scammed,
it is not beneath Pina to do this since she did tried to send assassins to kill Remi back in the early chapters while she was on her way to Demon's territory.
So the likely, to the Warden of that prison, this is very personal, the woman who corrupted his son got delivered there. In this changed ending, Pina's only punishment is to stay in cage, while being covered and offer prayers to prisoner forever until she died. So it implies the rape and torture still or could happen anyway after the warden backstory explained earlier, just not that obvious, remember this manga is not above murder and flashback rape (which what Pina originally planned for Remi).
So yeah
Incase you doubt me about the torture part, early of this chapter, if you didnt realize it, Remi is doing experimental torture for both of the man and woman that got kidnapped and carriage swept down the stream. Thats why near the end of the chapter she's convinced about the soul experiment gonna success with her giving birth, cuz she already experimented on it already.
