I don’t revisit many manga after finishing them, but Bokura no Hentai is one that I’ve revisited every year or so ever since. I absolutely cannot deny that it has had a profound impact on me, helping me figure out aspects of my own identity. However, with the increasing awareness of social issues like gender and sexuality in today’s climate, some of the things in this manga have not aged amazingly well.
Chapter 40, in particular, is very ehh in a series with otherwise amazing trans rep for 2012. I understand the authorial intent is to mirror the way the three leads first met through a crossdressing site, but Marika has been living life as a girl for a while, shedding the guise of crossdressing to lead life as her authentic self; a central part of the metamorphosis/transformation as stated in the series’ title. It just seems counterintuitive to then cast her back into this role, make her call herself a boy and saying that she’s ‘dressing up as a girl’ in a crossdressing competition when... you know, she is a girl, she is not crossdressing, and the main cast should be well aware of that fact by this point.
Additionally, as I get older, the displays of adolescent sexuality (particularly through Osamu’s character, who leans a little too close to the All Gays Are Promiscuous trope for me not to mention) get more and more unnerving. Like, I just feel gross while reading it? Of course, I’m not saying that CSA is supposed to lift your spirits because that’d be even worse, but the displays of adolescent sexuality with this kind of art style are... questionable, to say the least. I can see how that can deter readers, especially since it’s mainly used as a plot device or as backstory in Osamu’s case. In saying that, none of these encounters (including the sole consensual and somewhat healthy one) are sexualised or portrayed as titillating, which is a pitfall a lot of manga of this type tend to fall into. I mean, you shouldn’t need to congratulation authors for not sexualising their underage characters, particularly those that fall in the 12-14 age range, but you’d be surprised.
Generally speaking, I agree with 20YLFSG below in that CSA is not treated with the gravity and delicacy it needs to be in this manga. It is used to somewhat artificially make the story darker and ‘more adult’, and while it definitely fulfills its purpose in that respect, it’s a definite problem that’s prevalent throughout Fumi Fumiko’s works
Spoilers for other works she has contributed to:
! like qtμt/Cutie Mutie and Sakura no Sono, the former being exceptionally bad about it. Bokura no Hentai is like a sweet summer’s day in comparison.
In spite my criticisms, I think Bokura no Hentai does an exceptional job in rationalising and deconstructing the otokonoko genre as well as providing a transgender perspective within a work of this kind, seeing as the two are often equated at the best of times. You can tell Fumi Fumiko did her homework, which is always good to see when you're trying to represent a minority group you do not belong to. It’s worth a read if you can stomach 12–14-year-olds being put/putting themselves (thanks Parou) into sexual situations and questionable decisions made regarding LGBTQ+ characters. However, while reading, just keep in mind that this work is a product of its time, and while it isn’t all that progressive or radical nowadays, something like this was previously unheard of in this genre.
(I don’t count Wandering Son as something in the otokonoko genre for obvious reasons)
I recommend, however, skipping Chapter 40 if possible as that chapter is not thematically consistent with the rest of the series, and steering clear of this manga all together if sexual depictions of minors is something you absolutely cannot stomach.
