Juvenile and repugnant rape fantasy. But looking at the comments thats clearly what its audience wants. The main character isn't an antihero. There's nothing heroic about their actions, by their own admission half of the appalling things they do are unjustified and done largely for their own desire and amusement. Even that might have been redeemable if it had been executed well. But it isn't. There is no characterisation, even the protagonist is a barely there two dimensional cipher. He's also, clearly and explicitly, a moron. He pontificates about his cunning but then fails to grasp the most obvious results of his actions. Getting surprised and angry when his actions have disastrous consequences for the only people he "cares" about. If it has been better written and less gratuitous there might have been something interesting to say about the consequences of abuse. But that single idle thought has more nuance than the entirety of this work.
There is no world building, the power system shown has no real rhyme or reason to it, is never explained and frequently contradicts itself. There's no real over-arching plot. The art isn't too bad. But the main content of the manga is the main character raping people into submission (often virgins so you can be sure to frequently get a charming close up of blood dripping from their vagina) or butchering people. If you consider that interesting or appealing then this is for you. But that's all there is to it. It's garbage.
