Honestly, Takumi leads me to a question. What kind of psychological state are both of our protagonists in? I'm sure it's a question that doesn't matter, but if you think about it, Yona was a regular woman, but when she landed onto the island, she didn't bat an eye to all of the murdery death that occurs on the island, she can hang and butcher people without batting an eye, and only freaks out when she is being raped. Even getting downed by enemies (not grabbed) doesn't see any kind of reaction.
Meanwhile, Man will do pretty much all of the above listed, but will visibly enjoy raping any and all women all over the island (including Yuno herself)
The natives are probably mostly used to the island and it's tendencies, and the friends from the ship are rattled about what goes on. (excluding Takumi) I'm putting WAY too much thought into this, but it's interesting to think about.
