This manga is a pain in the ass to read. Even though I enjoyed it, I can't give it a good rating, simply because it's just bad.
Hear me out. If you enjoy tiddies and butts, with no more than implied sex (I can't remember if any sex scenes were drawn, stopped reading a while ago) then by all means, read this; in fact, I encourage you to read this, if that's your reasoning.
But if you're expecting any type of story, for the meanwhile, stay away. Far away.
While the actual story is good and the plot is above average, the mangaka never bothered going into detail and instead has been milking the fact that everyone wants to see naked women.
I seriously liked the plot behind this. I actually told a whole bunch of my friends that I've found the fated "Hentai with Plot" I've long searched for; but it only ended in disappointment when, not even after 10 chapters, the story is put on an absolute halt. Instead of getting the actual pulp and flesh of the story, we keep getting sidetracked with fan content that just showcases one of the other 5 survivors.
They're all assholes, too. Except what seems to be two of them. One is basically a rapist, who has fucked every single girl and a half that he's laid his eye on since finding out he's among the last 5. Another is someone who instantly accepts his position, and also uses it to fuck literally anyone he wants, even to the point where he points out girls he wants to fuck on the street, and has them basically get abducted. Another is a nerd who never had life fair, but gets excited with his situation and fucks someone he's loved for a long time (to be fair, she wanted it as much as he did, but he could've been less of a prick about everything.) Don't remember/don't know about the last guy.
Then there's MC. MC is saving his penis for a girl named Elisa. Elisa was someone who found out about the virus that killed every man, and finds out it's man made. MC gets suspicious of everyone around him, and now we're waiting for the rest of the story.
Now, the story is great, but there are way too many variables to have to maintain an eye on this early into the story. For starters, we have the "instantly accepts his position" guy interacting with MC's sister, who he sees on the street and asks the lady to get her to fuck him (aggravating cliffhanger which will probably only turn for worse seeing as 50% of the entire story so far is fanservice and NTR has a disgustingly (and extremely disappointingly) high demographic).
But when I said "waiting for the rest of the story", I didn't mean waiting for more pages. I really mean the story is at another halt, yet again. Constant fanservice chapters and randomly snapping into the lives of the other 5 men alive is getting beyond annoying. At first, I thought "It's pretty cool that the mangaka thought of not making the entire series revolve around the only one alive". Any one of them could be the MC's, but they're all pretty much ruined because they're all absolute dickheads ('cept for the nerd kid and MC, obviously.) Once that happens, I don't want to see them anymore, and I can guarantee that nobody else who actually looks forward to the story wants to either. They're nuisances. You could say "Well, that's the intention, isn't it?" Yes, the guy wanting to fuck MC's little sister is an intended aggravation, but that's it.
So, TLDR time. Basically, the entire story so far (that's translated, at least) is: MC wakes up, immune to man-killer virus, we find out it's manmade, only 5 alive, latest chapter includes MC unlocking a thesis by his lover Elisa, his sister is about to be NTR'd by one of the other 5 guys, only 2 of the 5 seem to be fine people, one of those being really good (MC), and the other two are absolute dickheads who should be put down at the world's earliest convenience, as well as the people who run the onahole hellhole (I had to make that joke, I'm so sorry but it's genuinely true).
Basically to the basically, the story is good, but after an entire year, when you sum up the entire plot, it's literally just "immune man wakes up to find the world is full of girls who want to fuck him but he refuses because he wants to find this one girl who not only does he love but has potentially uncovered the secrets of this virus that wiped out all of 'man'kind."
Extremely shortened review and recommendation: Stay for the art, leave for literally everything else, ever.
