In a near-future world where a pandemic has drastically reduced the male population, humanity faces a crisis of declining birth rates. On a remote island town called Kawashima, the government has established an advanced academy where “practical sex education” has become mandatory as part of national policy. You play as a student who moves to the island to attend this academy. What begins as a rural slow-life of fishing, crafting, and exploring soon intertwines with unique lessons: classmates, seniors, and adults are paired for daily “practice sessions” aimed at countering depopulation. ​

This game is incredible, it's the exact type of porn that I like that's hard to find. All the heroines and side characters are great and so are the CGs. The art looks really good and there's a wide variety of scenes.

NGL this game is an insane grind. The map is huge, the missions confusing, the crafting system annoying. It's generally just not worth it unless you are into getting cucked. you will spend at lease 2 hours at the start of the game just aimlessly running around with no clue what is going on before you get to finally bang your "randomly assigned" partner. Which leads me to the next issue. There is nothing random, choices dont matter. its all predetermined. Literally none of the choices you make during the game affect the game in any way whatsoever. Again, basically none of the choices you make matter. You will grind for an hour doing missions for people just to watch them then fuck someone else and not you. god forbid you make it far enough and like your partner because suprise! she gets gang-raped by every single man on the island. Wow! you did all this work for me?! thanks so much, youre the best MC! alright im gonna go fuck someone else now. in summary: you will spend hours running around doing the most confusing grindy gameplay to get rewarded with scenes of someone other than you having sex with the heroines you like. And as for the one heroine that actually does like you, and doesn't go around fucking other people, well, your reward is getting to watch her getting fucked by other people, specifically getting gang-raped by 20 men.

Had to review this one. I thoroughly enjoyed it. For a rpgm h game, it has some good content and scenes. It has alot of h scenes, and I really liked the characters. Story/dialogue is pretty funny as well. There's enough content and things to do, and I guess the only downside is probably the grind to get materials. There's definitely still room for improvement and potential for more content, but for what it is, I really liked it and I hope to see more these in the future.

really enjoyed this game! - good cast of character(though wish we had more hairy pussy) - very good art, with amount of charcters and scenes theres some variants of scenes but overall everything is very well done - the farming(like actual farming not grinding) kinda takes a back seat in the mid game, crafting isnt too hard after the first 3 hours - lots of reading but can skip all of it - scenes without MC with a shota, nice additon Overall a solid 8/10 IMO

The game has great art and a wonderful summer school-life vibe, complete with charming characters and a massive map. But the pacing is a nightmare! Two hours in and there's only been one scene involving the MC. The progression system is messed up. As a school life game, it does not progress by sleeping in your bed. Instead, there is a "!" mark that appears in the classroom, which only appears when you clear certain "!" marks around the map. If that is not enough headache for you, you can roam around the island, DOING RANDOM QUESTS AND GRIND FOR NO REASON at this early point of the game, just like I did.

Starts off rather strong and promising (despite it being very slow-paced). The teacher specifically mentions multiple times that students should stick with pairs but it isn't a hard-and-fast rule, and that sharing/cheating has historically been disastrous. Many students even ask about sticking with pairs, and the MC (who you play as) can answer. So even if you're faithful and if both the MC and selected heroine stick together, she can just randomly cheat anyways, despite everything prior suggesting otherwise. This game would have been significantly stronger if they allowed both routes (loyal, but getting teased by the increasing volume of options, as more and more potential heroines trickle in throughout the story), or the easier-mode slut-fest (as the game is forced to be but pretends you have choice in it being not the case). The whole sharing/cheating/NTR in of itself doesn't bother me inherently, but it's more how poorly done it's done collectively, and adjacent to such; how it gives the player massive illusions (again from the many dialogues with all of the other characters) that you can choose loyalty, but instead the game forces to be cheating/sharing/slut game. It's hard to even suggest picking up a 100%/gallery save to have a look as while the artstyle is generally pretty nice, there's basically no animation, minimal variation in stills/CG, and most of the work is in the dialogue, world and character-building, and build-up prior to each main (H) event. Very disappointing even though I knew the general premise of the game, however, it's very poorly handled and executed. It feels as if the developer got slack or lazy in piecing it together properly.

This game is top-tier: great art (even if censored) and the best (the best ) writing I've seen in RPG maker. BUT it made me grievously angry. Look, I fuck with NTR, but not when the protagonist is a fucking champ: biggest dick and greatest heart of a generation, and yet - AND YET - to these girls you're grinding affection for, you are no one special. In fact, with the exception of the main heroine, you are explicitly a sidepiece for their emotionally fulfilling relationship with their randomly assigned partners - losers who are definitely not cooking them their favorite meal with ingredients they grew themselves. But the game was good - really good - so I forged ahead. I grinded for 20 hours through all the sidequests, maxing everyone's affection, determined to at fucking least get them all pregnant. Well, guess what: even though there's a stat tracker with a promising "births x 0" for each heroine, this game has no pregnancy tag. They won't even kiss you. But you know who they will kiss? Shota. Fucking. Oone. I am not gay, but when the post-game scene offered the change to ruin that twink's ass, I watched it with a flacid cock and a smile. Would recommend. Will never play again.

First, to clear things up, the game is extremely tedious at the start. The map is huge, and you have to run around blindly to find events. It also has a grindy crafting system that feels like it's there just to pad the playtime. However, and I say this with a big "however", the art and the premise are so fucking good that it honestly feels worth it, even if the gameplay is dogshit. I'm not joking, this is some of the best looking art I've seen in a hentai game. I love sex education story premises, and I also love that the main girl is shy and embarrassed. This seriously ticks all my boxes. There's so much focus on the girls assholes, and I fucking love it. Their bodies are all unique as hell, with all body types represented, from skinny to flat to big tits. It's sad that it's censored, but the artist still made sure to draw the assholes in a very detailed and unique way. I do wish the girls had pubes. This game would legitimately be one of the best if they did. Only some random women have pubes, not even the teacher or the policewoman. It also has so many scenes and different positions, but I wish there were more footjobs and maybe even armpit jobs. If you use MTool, all the grind is gone. You can enjoy the game without all the shitty crafting and gathering, just use MTool and play it. I'm not joking, the art and the characters are top tier.

Amazing game, that makes anyone who likes schoolgirls and swinging hard as rock. One of the best in genre.Only problem is a fucking farmer simulator mechanics. Without thoose mechanics could be much better.

Is this game perfect, not at all. It has it's flaws. But for what ever reason I loved this game. I liked all the heroines and enjoyed the crafting system even if it was time consuming at times. Raising affection can take a while but I cared about the cast of girls enough to want to keep going and because of that it felt rewarding. There is a lot of H scenes. It can take a little bit to get to them but I liked them. When it comes down to it I just had a lot of fun playing and I had a really good time. This game won't be for everyone but if you can get past the slow start there is a ton of content here to really enjoy.

wow this game has so much going against it, but holy if you could just look past it all, this offers one of the best eroge experiences ive ever had. the main warnings: - the beginning of the game is slow, it will not feel worth your time, nor your effort, it takes a while to even get unlock any h-scenes. the main gameplay loop will find you traveling an annoyingly huge map checking in on like a dozen heroines every day, as well as trying to find random side quests and events with no pattern. some QoL eventually rolls in, like having super fast movement speed, but if you cant bear the tedium or the game's h-content doesnt feel worth it, then truth be told it really might not be worth it. after drudging for like an hour or 2 though, if you can get used to it all, there'll be events all around that personally made it feel worth the time and effort. - everyone is verrrry casual and sexually open. the "heroines" play around with maaany partners, all consensually. if you cant handle that setting, move on. as for me, you cant find this type of world in eroge so easily, its all very wholesome if you accept it lololol. despite that tho, some characters still value intimacy/loyalty. you'll still see them fool around with other guys, but not as hardcore... its weird but its cute. if you could get behind it all, imo this game is rich in simple yet erotic scenes. there is a lot of variety, and its hugely complemented by the variety of characters as well. absolutely love every character's designs, specifically the variety of body types and how readable their personalities are, but i also love their writing as well. the game has a lot of non-h dialogue all over the place, and they really help to build the immersion, each character's day to day life, as well as their relations with eachother. overall the game design is incredibly tedious, you couuuuld totally just get a 100% save... but get past it all and i found myself incredibly immersed in these simple characters in this erotic world one weird tip for anyone starting, get the woodcrafting book at the shop and sell "finland torches", easy to make and high profits also miyamoto best girl and the devs knew it

Mf below me is lv99 gooner and are too lost in the sauce to think that people don't get dissapointed when the promises the dev made aren't fulfilled. Nevetheless, very fapable game minus the extreme grind if you don't cheat and some surprised NTR/sharing due to tags not being properly added. Story-wise, typical porn plot so nothing to write home about.

This game is PEAKKKK !!!! Screw these delusional c*nts that gave 1 ratings, MAN UP. This Island is free for all, everyone is fair game! To clarify: - Shota fucks everyone (yes) - MC fucks everyone even MORE than shota does What makes this game PEAK to me: - every girl, have, UNIQUE asshole drawn. I did saw the dev specialized in Anal drawings. 10/10 RRRRAAAHHHHH - Tits and breast also have DIFFERENT shapes and sizes - The sex record progression is fascinating, as everyone keeps increasing on daily basis. OFC IT WILL!! THEY'RE HAVING SEX EVERYDAY!! - Most (normal) fetish are included in this game. There's only 1 bestiality and 1 Yaoi with shota iirc The only downside is, there's no pubes drawn on the main FMCs. While the NPC(others) pubes are drawn PERFECTLY the asshole pubes ARE TOP NOTCH TOO, WHICH IS REALISTIC!!!. The dev of this game have TOP TIER drawings of body parts, believe me on this! P.S Do yourself a favor and use saveeditor to get necessary items

In a near-future world where a pandemic has drastically reduced the male population, humanity faces a crisis of declining birth rates.

You play as a student who moves to the island to attend this academy.

See the theme are about Pandemic has drastically reduced the male population. On certain academy on island they can even afford of pairing each girl with boy with same ratio (so not 1 with many but 1 on 1 pair) that alone already break all immersion maybe if male are only mc and shota it's still understandable but not. And if it hard for you to understand harem literally "Harem is a genre of light novels, manga, anime, and video games focusing on a main character surrounded by multiple potential romantic or sexual partners. Originating in Japan in the 1970s, its popularity increased during the late 1980s and 1990s with the advent of dating simulator games." Source Wikipedia With harem tag players expect something like that not grinding mindlessly but getting unskipable scene where other girl fuck other boy as reward and there's no ntr tag and you must grinding too just to unlock recollection room, and wth anal scene more prevalent when the goal are literally procreation? That alone already deceiving players so getting bad review and even harsh critic are normal at this point this is not about genre anymore but dev deceiving players with false tag and promise and for adults game tag can be considered as contract so when one party violated the contract then they better prepare for consequences.

I quiteenjoyed this game. The art is good, lots of scenes and the story of the budding romance with the FMC despite the noncommittal world they live in was quite cute. Wish it was less heavy on the RNG though, collecting stuff like silver or that accursed otter meat was an actual nightmare. I don't think the one star reviews are being fair to the game, but then again I went into this game blind. Maybe if I had been following this game like the others I'd be angry too, but I still think one star is a bit of an overreaction.

Quite a well made game, took a while to finish, there's a lot of content, and while the grinding and pacing is a bit off (I cheated to pass the grinding, because it's a bit too tedious), but outside of it, this game is quite good. Character design is good, each character feel different and unique. The world and maps feel polished compared to other RPGM. The gallery is solid and in hand, the amount of story is also solid.

Played the game without thinking and looking at the tags and guide so my experience is not as bad as 99% of the players.Still it deserved all the hate it got due to how deceving the tags and description are Anyway heres some aspect that i think the game did ok that helped me complete the game 1.Holy art 2.Holy varieties 3.A surprisingly well made story for a game like this with not just h but also the daily talk,conversations 4.Dont know if this is changed in the lastest version but almost all the girls got some kind of romantical feelings for you despite how ppl are saying they are falling for shota.I played the whole game end except for madoka, everyone else had or starting to admit that you are special and if not for the society pushing them to be slut then you would be their partner (kinky as hell) Potentially harem for part 2?Maybe idk

>Start the game >Meet Shota at school, seems like your classic friend character >Nurse appears, clearly wants Shota >"Oh okay, Shota will probably get to fuck the Nurse, aight I can live with that" >Meet the other girls >Fall in love with Madoka >Next day >Nurse is fucking shota in the middle of class, as expected >She announces we are all going to have our first time soon >"I want Madoka" >Assume affection will have something to do with how the pairs are chosen >Spend the remaining days raising Madoka's affection >The lots are drawn >She gets paired with Shota, who is not even a virgin at this point >She seems happy about it >"Teehee good thing you already have experience, you better take charge" >My heart sinks >I end up getting paired with loser girl >The four of us talk after class >Madoka asks who I had hoped to be paired with >THIS IS MY CHANCE, MAYBE WE CAN SWITCH >"I... actually wanted you, Madoka" >Loser girl gets sad and runs away while Madoka calls me an asshole >Turn off the game View attachment 5730947 Please... add the NTR tag... but jokes aside I got to relive my worst trauma as a teenager, losing the girl I wanted to someone else and having to settle for her friend lol. It seems mosts players felt the same thought the game, even if they did not like the same girl as me. The whole early game feels deceiving, you are introduced to the affection system, you are told that love raises the chances of pregnancy and since you are also one of the few students that does not live at the dorms you assume you can invite girls over but in the end the affection is just part of the grind, there is no pregnancy and living away from the dorm only adds to the dread of knowing that while you are forced to scavenge for food your favorite girl is getting gangbanged by your classmates.

From the game and ingame description that most of the male population died. I was expecting, that there are only 2 males on this Island. The MC and the Shota. And this would be a great idea that only this two gets the girls, alone or together. Because I only found out about this game couple of days ago. It doesn't bother me that much. I really like the characters, and the scenes are well done. There’s a lot of variety, which keeps things interesting. However, the RPG elements really bothered me, they felt more annoying than engaging. I give the game a 2/5.

This game only has its artstyle going for it, the gameplay is slog to go throught for low rewards, there is no harem and no impregnation (and a LOT of anal for some reason) in the game revolved around super low birthrates because of the lack of men, and of course, the suprise NTR, this is on my list of Hgames i've been the most disappointed by. The developers are aware of the situation and will MOST LIKELY work on the game so you can avoid the "NTR" and can freely choose the heroine. Don't trust the comments saying there is nothing wrong here, or you will get jumpscared by the heroine you're working on in the middle of a gang-bang while you just watch (or getting piped by a shota). https://ci-en.dlsite.com/creator/25260/article/1718338
