Not too bad

This is a story about magical girls, but not really. Basically, it's two forces against each other. Instead of the tired concept of "good vs evil", it goes for "order vs chaos", which sounds kind of the same but isn't. Neither side are "kind" or "just" as such, both are messed up to some extent. One wants chaos and the evolution that follows, the other wants peace and order, which can also be equivalent to stagnancy in a species. I guess you can see one side as the laws of nature, survival of the fittest and the other side as a more moral, scientific approach more in line with our own standards today.

The protagonist is a chain-smoking, OP, violent and trash talking delinquent. This is where the comedy comes from. Honestly, the setting itself is pretty absurd, the mc is as well and you can feel that the author went all in trying to create the opposite of what a magical girl should be. It's pretty amusing, especially at the start, but I feel like the author failed to push through and keep on going in the same vein, not being creative enough and it's as if the genre shifts quickly.

I feel like it should've focused more on comedy than it did. If it was more nonsensical, going all out with the gags, it would be hilarious, but somehow it turns into a kinda serious story with a nonsensical and stupid basic setting. The jokes are too much of a one-trick pony. Essentially it boils down to only a few basic things introduced early on. Kayo, the mc, doesn't like people with big boobs. She's overly aggressive all the time except when eating or smoking where she brightens up and goes into bliss. She smokes heavily all the time. She eats tons. She doesn't give a shit. She beats people with little provocation. She pisses people off and is OP. It all boils down to these things, over and over and over again. It quickly stops being funny, instead just normal, which means the story stops being funny and all that stands out is the plot itself which isn't particularly creative or interesting.

That the various creatures/"gods" that operate in the background and is either in the chaos or order camp are idiots and acts irrationally isn't that amusing to me either, because they're not wacky and random enough. I really feel that story writers need to understand that you should keep to a setting all the way to the end. If it starts out as very comedy heavy that makes little to no sense, you can't just make it more and more serious later on. The previous settings run contrary to the new developments and I don't like getting into a genre for, say, gags and comedy and then having it change to drama and action with the same gag over and over again because comedy somehow became a passing thought. At that point, it's just lazy writing. Gotta stay creative with new jokes and new developments that reinforce the previous genre/settings to make it stay fresh or end it after a few volumes.

Still, it's interesting enough to read for sure even if things are starting to get a bit dull after 11 volumes. I feel like we should be getting close to the end of the story unless the author does a major asspull, because at this point power levels are starting to equal and even go beyond the "gods" that granted them and pretty much every character of importance should have been introduced. Maybe 2 volumes more until the end, I'd say.

It could've been much more, but the author stopped at the initial gags and never explored potential new grounds. So, 7/10 for above average but not awesome.
