Boku Joshikou Ni Nyuugaku Shimashita (“I Enrolled In A Girls’ School”) [English, 43 pictures], by Shinogi A-suke
This is a start we’ve seen multiple times in hentai, a teenage boy enrolls a formerly all-female highschool that just opened itself to males, and he’s the only one who succeeded the entry test. Past a few bewilderment moments (the girls had zero sexual education courses, they have no clue how babies are made), the girls remember they’re ojou-samas with raging hormones, and the class turns into a fuckbuffet. The boy enjoys the sex, but it’s evident his opinion isn’t asked.
So, yeah, it’s a bit weird, the girls being 100% in charge I’m not tagging this as harem, but if you just care for the sex, it’s pretty good, 43 pictures and lots of girls :3
Still, there’s whiteout censorship, you’ll see outlines, but no more than that. It’s terribly frustrating.
Release credits are for Translator39, thank you!
By the same artist, I also share Iinchou No Koibito (“Chairman’s Lover”) + the bonus sort-of prequel Iinchou No Aisatsu (“Chairman’s Introduction”) (237 pictures), Yuugen Onsen Kidan + Yuugen Futsuma Kidan, Ni No Jijyou, Sister Play chapter 1, Prisoner, The Secret Garden and Unfitting Puzzle (Uncensored version).

Between Oba-san at the cafe (Page 9) and the mysterious lady in business suit and glasses (Page 10), something’s a-brewin’ for our young male protagonist. I’m willing to stick around to see just what that is, but for now:

The National Committee for the reversal of declining birth rates in Japan would like to know your location.
Thanks to my using THIS, they’re not going to find me (fu-fu-fu)

Harem stage initiated…
Bypassing censorship…[DENIED]
Damn, guess this game is unplayable, I’ll wait until they work out the bugs, maybe get the GOTY edition.
Well it looks like we will be seeing more of Kujou-kun’s adventures in Ojousama land. Hmmmmm I wonder if this is endorsed by the National Committee for the reversal of declining birth rates in Japan?.
Could be that the objectives of (as Oliver I believe dubbed it) “The Great Impregnation Indoctrination Plan”, endorsed by the National Committee for the Reversal of Declining Birthrates in Japan, overrides and supersedes the original mission and vision of this elite former girls-only educational institute (see Page 1 for details)
*beat*

This is just the first part. It says on the last page that it will continue in the August issue of Comic Mugen Tensei, published on the 5th of July.
I missed that. Excellent news!!
It turns out it’s actually a 197-page long tankoubon. So far, searches only reveal a Chinese translation:

Notwithstanding, it’s on my list of one-day-to-do projects … unless someone else gets to it first.
