I don’t recall where it mentioned having his skin taken off, it might be a mask? There’s aspects in the story that are rather modern (notably the swimsuits that were CLEARLY not from the era European inspired villainess stories tend to reference) so it’s possible, especially when akuya has a lot of money
It wasn't mentioned specifically. I'm making an inference since they zoomed in on the scars on either jaw several times while her father was impersonating the Baron. Scars that were not there previously.
I'm so confused how the Baron is still alive to become someone else's sex slave. Didn't his face get cut off? Skin is a vital organ, and the shock of having such a large portion removed is enough to kill a person, and the Baron doesn't seem healthy/strong enough to survive such shock.
