Not bad after all...

I avoided this for a long time though I've enjoyed the mangaka's other works. From the description, I expected this to be mindless, pointless smut but I liked it a lot to my surprise.

The characters are great, I especially love Gingaku. His antisocial disposition and cluelessness/denial when it comes to his own feelings is so endearing. He also has a lot of baggage and issues which makes for a pretty deep and interesting character. And Kayanoya isn't your average uke being forced to submit yadda yadda yadda. He has a brain of his own and the will to use it, he's just in love with Dr. Gingaku and chooses to be "used" by him. I really liked it how Kayanoya was pursuing Gingaku in his own way. The whole setting too is interesting and definitely something fresh with the futuristic sci-fi angle.

As for the smut, this manga has gotten a lot of needless shit. There are yaoi mangas out there with sex in every chapter, rape, public sex and threesomes even foursomes and you call a manga where the seme hasn't even touched his uke with his bare hands until the fourth chapter super smutty? Gimme a break. I'm not saying all the stuff that does go on in this manga doesn't count but this definitely isn't one of the most disturbing ones out there, not even close. And the beastiality claims seem to be just BS. I'd label it more like...uhm...mecha? Machines anyway, not animals!

If you're only into soft core yaoi, don't bother. But this was a lot better than I thought it would be. Fun, sexy and entertaining.

So in my so humble opinion it is not "porn" though the sexual content may be excessive, take into consideration that this is the man's profession, and his hatred of touching others, it was sort of necessary. I really hope to see the upcoming chapters because despite the admittedly excessive sex the characters obviously had quiet a bit of untapped wealth in their unique personalities and pasts, so I'm hoping that as it progresses we see much more of them so to speak.

On another note, though there is quiet a bit of sex, like elfee pointed out this is fairly tame compared to quite a few works, and if you are going to read something labeled yaoi, you should be prepared for works like this. If you want something tame, Shounen Ai is much more for you.

I felt compelled to leave a positive review due to the gasps of horror below. It's not like... grotesque or anything, porn-wise. It would say if you can't handle this, then maybe a good quarter of yaoi I've seen would be 'too much' for you; stuff like latter Asami Tohjoh, for instance. But that aside, here's what I liked: the seme is hot!! He has this touch aversion (wears gloves all the time) and prefers machines to people, but is super-attracted to the uke, whose presence slowly corrupts him (in a good way). From what I can see of later chapters, he has a real character growth and becomes less of a shut-in with the power of sex (but more emotional than that). The uke has some spirit (compared to the tiny-girl-ukes who're always just submitting). Honestly, if you're ok with (actually just moderate) BDSM, the sex is hot, mostly 'cause the desire level is portrayed well and it's not like 'well, you're cute, let's do it'). As for the bestiality, it's no more 'real bestiality' than Ike Reibun's werewolf manga one-shot, but that's my opinion. It's just kink, and honestly more about exhibitionism and restraint, but YMMV.

weird-sick-disgusting.... one of the few yaoi that disturbed me so much....

if you look for something close to cheap porn, that's exactly what you're looking for... There was no romance in the story, the h-scenes were hardcore and sick, the only -kind of- interesting thing in the manga was the setting, cause the story is taking place in the faraway future but still this thing is bad enough to hurt my eyes...

Not recommened. sad

I'm a fan of the mangaka so i figured this would be along the same lines as her other stories... and in some respects it is... but its erm super hardcore o_O just a warning for other readers. Do not read if you have a heart condition xD or if you have a mild disposition. I'm so far rating it 10 but right now the rating isnt accurate since theres only 2 chapters to go by. Once the series is complete i'll review the rating and change it as necessary. In general, not much story, just enough to get by, lots and lots and lots of smut. Basically porn with almost a plot.
