I find this interesting mainly as a character study for Yuuta (the only “realistic” character). Usually with stories about meeting “dark characters,” the protagonist is a blank slate, a “good person” who gets corrupted and sucked into wickedness.
But Yuuta is already a bad person. He’s already “crossed the line”, and rather than being a wide-eyed MC with generic reactions, he’s the kind of scum that most manga would naturally use as a villain. So, it will be interesting to see this kind of abysmal human act out the “protagonist role” in a story where he’s surrounded by other monsters.
Plus, these kinds of stories usually try and keep a clear line between dramatized/unrealistic ikemen serial killing and realistic crimes like beating of women. But this one mixes them together, and explicitly examines the blurring when it asks Yuuta what makes him so different. I don’t know if it will end up being that deep, but the choices already set it apart from the ones that would have all the same characters minus someone like Yuuta.
