Hoshino Academy looks normal on the surface. Clean hallways, serious teachers, track stars running around like it’s a shonen anime, everyone pretending they’re “future leaders of society.” Then you open your mouth as Sasaki Keita, this loud idiot with too much justice in his brain and zero filter on his tongue, and the whole place starts showing its rot. The game throws you right into it with that first crash into Rin, the photography club president, camera hitting the floor, her eyes going wide like she just watched her whole life savings die. No fancy introduction, just “you fucked up, now pay it back with your time and your body watching hers fall apart.” It looks cute at first, like some wholesome romance VN where you help a shy artsy girl keep her club alive with cool shots and after-school trips. You walk around the school from his point of view, always stuck inside his head, listening to his jokes and stupid comments while secretly getting attached to that girl with the broken camera and the stubborn smile.

Then the Principal starts to move. Daizo is that classic ugly bastard type, but here he feels more like a slow disease. You see him in the background in early scenes, just standing there too long, watching Rin a bit too close, saying polite things that feel sticky. The story doesn’t rush the sex, and that’s what makes it nasty in a good way. It’s all small touches. Extra “private” photography advice. A hand a bit too low on her hip when he’s “correcting her posture.” A scene where you’re hiding out of sight, POV locked in while Rin thinks you went home already, and you end up watching her getting cornered in some quiet room under the excuse of “helping her secure sponsorships for the club.” The game forces you to just sit there, helpless, as his fingers trace up her thigh, while she laughs nervously and tries to stay polite. You can’t stop it, can’t pick a hero option, it’s a kinetic ride, and that hurts in this delicious, stomach-twisting way if you like NTR and corruption. That’s the thing: the corruption here isn’t only about sex. It’s watching her trust slowly tilt from you to that disgusting bastard, seeing her texts to you get shorter while her “club activities” get longer, her outfits shift, her smile turn slightly fake around you but more real when she’s alone with him, and you know exactly what that means.

Sex scenes hit like a truck when they finally show full-on action. There’s this oral scene where you’re stuck watching from behind a door crack, the AI-styled CG really leaning into her messy, half-teary look as she’s on her knees, hair grabbed, choking around him while he makes her “thank him” for some club grant. You can hear her voice trying to sound like she’s not into it, but the game gives these little details that betray her body, like the way her legs rub together or the shaky breaths when he gropes her tits through the uniform. The BDSM stuff is not hardcore chains and whips all over the place, it’s more about control and humiliation in small steps. Being ordered to pose, to undress slowly for “artistic reference,” to let him touch where he wants while promising better chances in competitions. Later it escalates into prostitution-flavored deals, sessions where he loans her out under polite school words, and you’re just trapped in that POV, knowing she used to laugh at your dumb jokes and now lets him spit on her tongue. The romantic side with Keita never fully disappears, and that makes it worse: he’s still trying to be a good guy, still cracking jokes, still clearly in love, even as the game shoves his face up against the window while Daizo slaps Rin’s ass and calls her his good little pet. The humor never fully goes away either, which honestly pissed me off and also made it hotter; you’ll have a silly scene about some club mishap, then five clicks later you’re staring at Rin getting groped under a desk while a teacher talks in front of the class. The sexual harassment, the slow mental twist, the way she starts defending him when you complain, saying you “don’t get how the world works” while she quietly adjusts her skirt over bruised thighs… it’s not kind, it’s not “fair,” and it absolutely doesn’t care what you want. And that’s exactly why my dick and my brain both ended up trapped in this messed up school.

Diamond Memories is one of those messy, horny school VNs where you start thinking “ok, this is just boobs and jokes”, and then somehow you’re three scenes later watching a girl you actually like sucking off some random guy in a filthy alley behind the karaoke bar while her phone lights up with messages from her clueless boyfriend. The tone whiplash is kind of the charm. One minute you get goofy banter about exams and uniforms, next minute you’re staring at an AI-generated CG of a girl with huge tits kneeling between the thighs of a dude twice her size, her mascara running and her hand “accidentally” wrapped around a second cock coming in from the side. The art has that slightly uncanny AI thing going on if you zoom too much, but honestly it works for this. It feels like stolen porn pics mixed into a VN, which is funny and also kinda sleazy in the right way. Text is where it sells the scenes anyway. They actually let the teasing breathe: the slow hand sliding under the desk, the first time a shy girl gets groped on a crowded bus and freezes, then presses her thighs together instead of moving away. It’s not subtle, but the pacing of corruption is better than in half the “serious” NTR games on F95.

What I really liked is the multiple protagonist angle. You bounce around the four girls, and sometimes you realize only later that the guy who was so “nice” in one route is the same asshole lining up a cheap group sex deal with her behind her back in another. There is a school setting, yeah, but the story spends more time outside than I expected: cheap hotels, love hotels, back seats, the usual. One girl’s arc goes from innocent masturbation in her room, trying to copy what she watched on some shitty Pornhub clone, to doing a paid titfuck for an older man she met in a chat app. The shift is believable enough that it stings a bit, especially if you played her “pure” path first. Humor is just dirty and juvenile in a good way. Characters crack jokes about interracial porn tags, the size difference, even the fact that one guy is clearly modeled after those meme stepbro actors. And then that same scene turns halfway serious when she realizes she kind of likes having two cocks fighting for the inside of her mouth. If you came for romantic VN fluff, you picked the wrong door. Cheating is not a side flavor here, it’s practically the main meal. There are moments where the boyfriend is just a text bubble on the screen, sending heart emojis, while the girl is pinned against a locker getting fucked raw, trying not to moan too loud. The game doesn’t pretend it’s “morally complicated”, it just lets shit happen and you sit there with your dick in your hand feeling way more conflicted than the characters. I wish the UI for choosing scenes was less clunky, but whatever, I keep going back to that one classroom blowjob scene where the teacher almost walks in and she pulls off his cock at the last second, cum splashing on her notebook with her math homework. I still laugh at that. And yeah, it stains the page and the next time you see the notebook, it’s still there. Little detail, totally unnecessary, but that’s the kind of thing that makes this whole trashy package stick in your head.

This thing starts like one of those harmless school slice-of-life stories, except it never feels harmless. You’re this dude walking the halls, joking with classmates, peeking at asses in too-tight skirts, pretending everything’s normal while the game keeps whispering that nothing is. On the surface you’re just chasing romance routes and big tits, trying to figure out which milf teacher you wanna risk your future for, which childhood friend you’ll accidentally corrupt, which guy you’ll piss off enough that he starts eyeing your girl. Then it hits you that every flirt, every little “harmless” grope in the hallway, every blowjob in the music room is getting tracked, twisted, fed back into this mess of morality and mind games. One minute you’re laughing at some dumb humor scene where your buddy makes a joke about your porn folder, next minute you’re watching a scene of brutal violence and you’re not sure if you caused it or just failed to stop it.

What really got me is how your choices feel fine in the moment. You see a big ass bending over a desk and you click the option to touch. Simple. She blushes, maybe moans, maybe slaps you, sometimes both. Then three scenes later she’s crying about how nobody respects her, and the game doesn’t tell you “this is your fault,” but you know anyway. Same with the whole NTR / netorase thing. At first it’s kind of hot, letting another guy or futa girl “help out” your partner, just sharing for fun because you think you’re in control. The group scenes are wild, by the way, especially when the camera lingers just a bit too long and you catch your own character watching instead of acting. Voyeur mode inside the story itself. But little by little, jealousy starts to bleed into it. There’s this one route where you push your girl toward another guy as a joke, like “go flirt with him, I don’t mind,” and way later you catch them in a quiet corner, his hand already under her skirt, her breathing way too heavy to pretend. You can interrupt, dominate, turn it into a threesome, whatever, but that sick “maybe I went too far” feeling doesn’t really go away.

Sex scenes are not shy at all. Virgin loss with awkward eye contact, messy creampies where you’re not totally sure if it was consensual or just pressured, titfucks on the school rooftop while the city burns somewhere in the distance, rough oral that slips into domination, then flips and she chokes you right back with that sudden female domination switch. There’s drugs, too, and that’s where things get weird in a different way. Some of the best animated scenes come from those mind control bits, where you honestly can’t tell if the girl wants it or your character is just rewriting her brain to want it. The game doesn’t clean it up for you. No “safe word,” no soft fade out. You’re the one clicking “continue” while she begs you to stop and also not to stop. But then you have these strange quiet romance scenes with actual warmth, like holding hands in a classroom while talking about family you really, really shouldn’t be this close to, or lying naked beside someone after fucking them raw and talking about sanity and what’s real. Sometimes it even feels wholesome before it throws another cheating scene at you completely out of nowhere. I kind of hate that. And I kind of went back to see every single ending anyway.

There’s this weird horny comfort in the way the Academy feels both serious and completely trashy at the same time. You’re “the doctor”, the last one not dead or infected, but the game doesn’t really care about making you feel noble. It cares about putting you in a magic school full of witches who somehow always need physical exams that turn into groping, massages that slide into fingering, “magical checkups” where you’re basically encouraged to stare at their tits while pretending it’s clinical. The virus plot is just enough to make everyone act desperate. Girls knock on your door like, “Professor, I think the curse is spreading to my chest…” and yeah, you know very well what the dev wants you to click next. You walk around the academy, check the schedule, manage who gets what treatment, but really it feels like you are managing how quickly they lose their shame. There’s a management system tied to supplies and research and all that, but half the time you’re just min-maxing how many excuses you can get to see another girl undress for “testing”. It’s trashy in a way that actually feels honest.

The real hook for me is how much it leans into voyeur stuff without making it the whole point. There’s this scene early on where you discover a hidden passage that looks like it was built just for perverts long before you were born. Tiny slits in the wall, right into the girls’ bath, or the dorm showers, or the practice rooms where they do “focus exercises” completely naked because “fabric interferes with mana flow”. You can stand there, in the dark corridor, watching this one redhead witch practicing spells while she fingers herself to “charge the ritual”. You’re supposed to collect data about symptoms, but the game actually tracks how long you keep spying. The more you peek, the more the story bends toward corruption. It never tells you directly, but you start feeling that the academy itself is kind of alive, feeding on exhibitionism. One girl starts pretending she doesn’t see you, even though she clearly looks at the wall where the hole is. Another one suddenly “forgets” to close the curtain when changing into her cosplay outfit for some stupid school event. She wears these cheap magical girl clothes that look like they came from AliExpress, all pastel and too tight around her huge chest, and you’re sitting there thinking, “This is the stupidest thing” while also rock hard.

The best scenes are when the medical side, the magic side and the porn side crash together. There is a massage event where you are “rubbing a special potion” into a student’s legs to prevent the virus from spreading. It starts totally serious, you’re checking her pulse with magic, adjusting mana flow, that kind of nerdy fantasy roleplay. Then the camera slowly slides up to her panties. She keeps asking if it is “really necessary to go higher” and the game lets you be either professional for two seconds or just go straight to full perv. If you keep it clinical, she blushes even more, which somehow feels way dirtier. And of course, the more you abuse your role, the more the academy rewards you with new “duties”. You suddenly get asked to lead “intimate mana compatibility exams” in a locked room. Vaginal exams that could be normal, but you start thrusting fingers and the animation actually shows her trying to keep her dignity and failing. It’s not subtle. It doesn’t pretend to be. One moment you’re picking which student to prioritize in your daily schedule, trying to balance research and reputation, the next moment you’re buried between the legs of some top-ranked witch who swears she will curse you if you stop. The tone jumps all over the place and somehow that makes it hotter, like you’re always one step from ruining the academy completely and you kind of want to.
