By the way, maybe it's been mentioned here before, but I happened across a parallel series just completed on Mangadex, Yuugai Shitei Doukyuusei, with a diligent class prez trying to lead a sex-fiend classmate down a "better path."
Very different tone than this one (definitely ecchi, although not outrageously so), but still pretty funny.
Ecchi aside (because there's not that much of it? It's primarily gag stuff), I find myself laughing. It is charming.
Yes, the troublesome girl really does share a version of Hino's gonzo thought process, and I like the way the class prez has to struggle to maintain diligence and purity of speech and action while being scathing in her own thoughts--and being more knowledgeable about H stuff than she lets on.
If I had to choose one I'd take this one in a heartbeat--this is both funny and adorable--but the other series is definitely worth reading.
