Ana Satsujin is a thriller manga about a suicidal NEET and his discovery of a murderous neighbor through a peephole. I'm extremely new to the horror/thriller genre and in fact I avoid it in general, but Ana Satsujin was able to keep me curious and interested.

Story 7/10 - As you can expect from a horror/thriller manga with a character who's a psychopath, there are lots of violence and people dying. The story doesn't really have a plot, but instead it's more of a journey of how the relationship between Kurosu and Miyiachi can work and waver. There's a part where murder was being justified by the killer, which I find completely irrational but nonetheless interesting. The story likes to throw curveballs of which are mostly unexpected, but then again by the time each new character is introduced you'd already be thinking "welp, you're definitely going to get murdered."

Art 7/10 - The art is above average. The farther chapters you get in, it's less and less detailed compared to the panels from the earlier chapters. At some parts it's extremely watered down that it's laughable; I'd say "cute", even. There are times where the characters are presented as chibi, which completely detaches from the atmosphere of the story. It works well during the "tamer" scenes though, so I have no gripes about it. Even though it's a horror manga, the way it presents violence is surprisingly tame (kind of a "leave it to your imagination" style). It's so tame that there was even one chapter where most of the page was censored, followed by an apology note on the side by the mangaka.

Character 8/10 - Suicidals and psychopaths are pretty common character archetypes, but Ana Satsujin makes those two archetypes work together. In other words, they have chemistry. Kurosu finds another reason to live, while Miyaichi finds someone who can accept her. It's entertaining to read each of the characters' thoughts and actions, especially Kurosu's. He thinks and reacts exactly the way a guy who'd fallen in love with a murderer would.

Enjoyment 8/10 - Not much can be said. I enjoyed this manga a lot even though I'm not fond of the genre. The story was good and the characters were good. Also, I'd like to mention that the characters really like to break the fourth wall for occasional comedic effect. They also like to reference anime and other manga. It breaks away a little bit from the tension of whatever scene they're in, but I just accepted the fact that everyone is batshit insane.

Overall 8/10 - I personally think it's a good manga that can keep you interested and curious in every chapter.
