Okay now that the manga came to the part that I've been dreading but have been expecting for a long time. It is now safe to say that the whole incest premise is a setup of an effective argument. Is it a good point of discussing taboo topics and the psychological breakdown of being in their position? Yes, is it cleverly done? Not quite.
From the premise of a patient and a doctor being reincarnated into siblings, with the heavy emphasis that Sarina/Ruby had been inlove with the doctor since her patient days AND her actively declaring her love for the doctor WHILE Aqua is listening. It's not supposed to be a shocker that she will still hold feelings until this day. Like it's EXPECTED.
But what makes this icky is that personally from a writing perspective it's a wonderfuck of lackluster. Like this chapter is supposed to be the shocker of the current arc but it's just not.
Selfishness and trauma drives the narrative that Ruby doesn't give a fuck on being inlove with his brother. She is so far gone that her rationality is clouded. Aqua is just the same, in regards that he sets Ruby as a pawn in his game of chess where he pretends to be a grandmaster. Because he's aware of Ruby's feelings but is he doing anything against it? No he's enabling it.
I have more to yap about but maybe next time
Overall, the author should think of another way to make twists with their incest narrative if they really wanna make a taboo topic to be the main hook for their story.

This chapter just shows us how Denji's influence had helped on straying the Control Devil's innate need to control. Unlike Makima who was made to not feel remorse of controling humans, Nayuta does not enjoy the act like Makima does. She doesn't get the same battle high that Denji does when manipulating/killing humans.
That said, I'm not even keen on the idea that Denji likes the high of killing..
I absolutely love that when Tazune tried to mention his trauma it was just glazed over. He deserves it after everything he's done. He is a stuck up piece of shit who only thinks of himself. He goes for the easy path and never truly liked women, one can even go as far as calling him a sociopath.
What's sad is that men like him exist irl, and you can never know what they truly are until you've gotten close enough to get hurt. I hope everyone doesn't suffer the fate of that these ladies went through.
