I guess you'd like this if you're the average male or a particularly unsympathetic female, what with the pretty little underage waifs who show up naked all over the place. (Manga Erotics F doesn't have a demographic, so please don't say: "It's seinen, what did you expect?") In my case, there was way too much lolicon and fast romance/sex involving said lolis for me to be able to appreciate the psychology behind the stories. I added the 'lolicon' tag to the genre field, but in case it's ever removed, let this serve as a warning to anyone of similar mind.
I wouldn't even have written this comment if the underage nudity/sex/sexual exploitation were featured in 2 or 3 chapters, but in all but one of them? That was overkill. It would also have been okay if the stories specifically focused on the moral degeneracy of this futuristic city that has made adult x child sex commonplace, but... None of them were in any way dealing with that; they were focusing on entirely different issues. So why on earth were all the females involved ~12 or thereabouts? If the mangaka so badly wanted every story to have a romance element and sexual content, why couldn't he have made the girls women? There was no logical reason, so I can only assume that it's because Kitoh Mohiro himself prefers to draw younger females in sexual situations as opposed to older ones. And as a reader, I see no reason at all to approve of that if it doesn't contribute to my enjoyment or to the good of the plot.
On top of that, the mental/social/existential issues brought up, while quite thought-provoking, are not so earth-shatteringly unique that I'd recommend reading Kakutoshi no Yume at any cost; they're dealt with in most well-written works that feature dystopian futures, so any one of them would do.
Tl; dr: An okay quick read, but left an unpleasant aftertaste that restricted my ability - or, for that matter, desire - to speculate or dwell on what I'd read for too long. Which is quite the flaw in a collection of psychological one-shots, if you ask me. But if you like/don't mind loli elements... Enjoy!
