Yokosuka is a high school boy who gets the result of alpha in his secondary gender test. This is a big surprise since his parents are beta, so he is forced to attend the dating party for the marriage interview proposed by the city council. There, he meets many cute omega girls, but will he be able to find a nice girlfriend...?! Motivated by this, Yokosuka decides to undergo the compatibility diagnosis, and the kind of partner who was on the other side of the door with whom he obtained a maximum percentage of 92% was someone rather gruff with a look of unfriendliness that turned out to be... A MAN??!!
My Rate: 8
An Extremely Haphazard and Weak-willed Kiss (Zuborade Ikujinashi na Kiss) by Koshino takes a delightfully chaotic spin on the traditional Omegaverse tropes.
Our protagonist, Yokosuka, is a perfectly average high school boy who expects a perfectly average Beta life. Instead, his secondary gender test throws a massive wrench in his plans: he’s an Alpha. Because his parents are Betas, this sudden genetic jackpot turns his life upside down. Under pressure from a city council eager to pair off premium genes, he attends a mandatory matchmaking party.
Yokosuka is thrilled at the prospect of meeting cute Omega girls and finding a girlfriend. He takes a compatibility test to find his perfect match, boasting a near-flawless 92% compatibility rate. The catch? The door opens, and instead of the sweet, submissive Omega girl of his dreams, he’s face-to-face with a gruff, intensely unfriendly man.
Koshino is famous for injecting humor and realism into highly stylized genres, and this manga is no exception. While many Omegaverse stories lean heavily into intense drama, fated mates, and strict power dynamics, this story thrives on baffled subversion. Yokosuka’s expectation of a traditional, heterosexual Alpha-Omega romance is immediately shattered, forcing him to navigate a dynamic he never anticipated.
The contrast between the two leads drives the entire narrative:
Yokosuka: Slightly lazy, weak-willed, and easily swayed, yet incredibly endearing in his confusion.
The "Mystery Man": Gruff, unapproachable, and seemingly entirely wrong for Yokosuka on paper—despite what the 92% science score says.
The "haphazard and weak-willed" nature of their interactions creates a slow-burn, highly entertaining comedy of errors. Their high compatibility rating forces them into each other's orbits, and the friction between their personalities quickly turns into genuine, begrudging attraction.
Koshino’s art style perfectly complements the comedic and slightly chaotic energy of the plot. Expressions are vivid, exaggerated for comedic effect when Yokosuka panics, yet grounded and expressive during the manga's sweeter, more intimate moments.
A refreshing, hilarious take on a classic genre.
If you are tired of the same old brooding Alphas and fragile Omegas, this manga is a breath of fresh air. It balances the physical attraction inherent to the Omegaverse setting with a genuinely funny, character-driven romantic comedy. It’s lighthearted, a bit messy, and incredibly charming.
