This is actually not a bad manga. It knows what it wants to give and ends itself in an appropriate amount of time. 2 volumes is just enough to not tire of the concept while just starting to feel a reduced interest.
It's about "crisis girls", essentially girls with magical/supernatural/sci-fi powers in their genes/bloodline. The mc has a "bloodline of criminals", another main cast girl has the bloodline of assassins and the last one I know for sure about has was from a family of "mad scientists" and had been made to be toxic to every form of life. Why they need to be young girls is, of course, because readers enjoy the visuals and cuteness, right? They're gathered by the government, assigned caregivers and raised to be crime fighters like your typical magical girls, though they seem to only deal with supernatural things.
Anyway, the first/second chapter as the one that made me laugh out loud a bit, not because of the mc herself but rather because of the incredibly twisted morals everyone in this story. After killing a huge, sentient penguin monster, we see in the next chapter that said monster is clearly dug out, stuffed and turned into a god damn roller coaster attraction as the reporters take great joy in displaying said feat. Damn that's harsh. Then how she'd rather save cake than humans and prioritize pets over humans, well, it all gives a pretty funny vibe.
The main comedy, in my opinion, derives from the "gap" between expectations and reality in this story. She's very cute and innocent but does incredibly cruel things as if nothing, perhaps out of childlike innocence. She's also a necromancer and deals with corpses all the time. Then there are silly characters like an evil loli and a bipedal chihuahua teaming up to commit crimes, always failing in the end and quite miserably at that. Clearly all these crisis girls are severely out of touch with normal human morals, much to the chagrin of their caretakers. To be perfectly honest, it doesn't stop at them and most humans in "crisis city" seems to be warped/wacky and weird, perhaps due to all the weird monsters or "crises" showing up so often and getting dealt with purely with the power of little girls with superpowers.
This setting would probably grow old fast, but 2 volumes was, as previously mentioned, just enough, not too much, not too little. Give it a shot, spending a few hours at most isn't a waste for this in my opinion, there are a lot worse things out there to read. It's an easy and quick read, somewhat funny and lacking any drama and seriousness. Perhaps good as a buffer between more serious novels/manga/anime or whatever you enjoy on a daily basis.
