Who Is The Main Villain In The Case Study Of Vanitas, Vol. 10?

The tenth volume of 'The Case Study of Vanitas' really cranks up the tension, and the villainous spotlight falls heavily on Moreau. This guy is a seriously twisted scientist who’s been lurking in the shadows, experimenting on both humans and vampires in the most horrifying ways. What makes him so compelling isn’t just his cruelty—it’s how his actions tie into the larger themes of the series, like the abuse of power and the blurred lines between 'monsters' and 'humans.' Moreau’s obsession with creating artificial vampires and his complete disregard for life make him one of those villains you love to hate.

What’s wild about Moreau is how he contrasts with other antagonists in the series, like Charlatan or the Beast. While they have their own grand schemes, Moreau feels more personal, more grotesque. His backstory, revealed in bits and pieces, adds layers to his madness, making you wonder how far someone can fall when they’re convinced their work is 'for the greater good.' The way Jun Mochizuku writes him is just chef’s kiss—you get this mix of disgust and fascination every time he shows up.

By Vol. 10, Moreau’s experiments become central to the chaos unfolding in Paris, and his interactions with Vanitas and Noé are downright chilling. There’s this one scene where he monologues about his vision, and it’s equal parts pretentious and terrifying—classic mad scientist vibes, but with that gothic flair the series does so well. If you’re into villains who make your skin crawl while also making you morbidly curious, Moreau’s your guy. I’m still shook by how his arc plays out—no spoilers, but damn, it’s satisfying in the most messed-up way.
