It’s extremely heavy handed about sexualizing the little girls in a way that constantly teases either a romantic or sexual relationship - loli content is very much a commonplace (and tbh pretty gross) thing, but it’s usually the sole focus if its the point. The sheer amount of slice of life tropes that are fit into the show, most if not all of them being taken to an extreme, would be what makes it satire. It’s a common premise, taken to extremes.
My concern with people not recognizing it as satire is a multifaceted thing. The lack of media literacy in culture is a large part of it, the number of people who unquestioningly accept the presentation of women in the show another part, the terrifying loli fans a big big part…
I have no issue with someone not seeing it as satire, I miss things like that all the time, but the sheer number of people who miss it is concerningly indicative of many flaws in society.
It’s not an absolute descriptor - the most beloved works of satire use their commentary on the original work as the base from which to build engaging original stories. This anime in particular is just very heavy handed with its satirical takes, and it concerns me that so many people either miss (or outright deny, as if it is a criticism) that part of it. It speaks to flaws in society that I worry greatly about the implications of.
