Only one chapter is out, but since it hasn't been updated in months, it's safe to say that a review is okay to write.
Warning, this review may contain spoilers that relate to the “revealing” of each character’s personality.

Shinya, the main character, is a boy who dislikes women because of the trouble they cause- a boy who barely reacts and shows barely any emotions.

If you think you've seen every type of harem out there, you haven't seen one like this.

Abnormal Kei Joushi revolves around Shiina Shinya, a high school boy who scoffs as his friend squeals about a cute girl at their school. You see, Shinya believes that women never bring any good. He can’t believe that women are even the same creatures as him, but he has good reason.

You see, most of the women in this harem are yandere, an anime character who is psychotic or violent. Think Mirai Nikki’s Yuno, and we’ve got ourselves a match.

In Shinya’s life there’s a masochist (if you want to see boobs, here’s your chance!), a creepy girl who believes to be Shinya’s knight, a too-happy murderer, and a beautiful stalker. (The description describes a sleeping beauty and a wannabe vampire, but the updates haven’t shown us them yet).

In the beginning of the manga, you meet every girl one by one with no clue as to how they relate to the main hero or what their issue is. I enjoyed how the author revealed each character’s personality towards the end, throwing you off guard.

Another great thing about the manga is that the hero isn’t a typical weakling. He barely even seems to care that he’s surrounded by a girl who makes him whip her, two stalkers, and an insane killer who could slice him open at any minute. His only solution to it all is that women are “hard to understand”. For example, at one point the murderer of the bunch calls him outside to view the corpse she’d just killed. His response is, “Don’t call me to the scene of the crime,” and “Can I go now? There’s a new anime I want to see.” He’s calm, cool and collected- a definite change from the sterotypical 'gasping' main harem hero.

In all, this was a random, unique manga which I hope to see more of within the next few months.
