Autumn City feels like somebody mashed High School DxD, a chuuni light novel, and a Pornhub playlist in Koikatsu, forgot to clean it up, then said “yeah, that’s fine”. You’re in the shoes of Hiro, a pretty typical magic student type, caught between demon hunting, bureaucratic bullshit from “The Organization”, and two heroines who absolutely refuse to keep their sexual tension at a normal level. The game pretends to be about terrorism and supernatural crime, but then you’re five minutes in and suddenly you’re watching Kana, the tsundere mage, yelling at you for being a pervert while her hand is already on your dick. It’s that kind of tone all the time. The structure is a Renpy VN, but it keeps throwing you into these little combat scenes where you’re chasing demons across some farm world like a horny Dante who got lost on the way to Devil May Cry and walked into a doujin instead. The first world, the Wilde Ivy farm, has no right being as horny as it is for a place with cows and hay bales.

What really sells it is the combination of 3DCG Koikatsu style and voice acting. Kana’s voice is pure poison in the best way: she does the whole “I don’t like you, idiot” routine while moaning her lungs out in an ahegao during a blowjob scene, and it just screams light novel parody. One of my favorite moments: you just finished a sloppy titfuck with her in a barn, she’s panting, your cum all over her chest, and she still tries to scold you about “professional behavior as an agent”. Then the game swings hard into NTR land and suddenly those same tits are bouncing on some demon’s cock because you took the “wrong” path. The cheating / netorare stuff is not subtle at all. There’s a scene where you get literally knocked out in combat, wake up in some fantasy side-area, open the Extras Gallery later and realize there’s a whole anal and group sex chain you didn’t see where Angie and Kana are getting used while you’re gone. The game basically grins at you and goes, “yeah, that happened while you were being useless”. It gives you a “vanilla / NTR scenario” choice, but the line is blurry: even the so-called vanilla path still teases you with the idea that these girls could get stolen if you slip. Some people will hate that, some will… let’s say, need a new keyboard. The oral scenes are everywhere: handjob with whispered dirty talk in one world-jump transition, deepthroat blowjob as a “reward” after a successful combat encounter, Kana masturbating while spying on you, Angie stuck in an older, more “milf-coded” role that really pops during a threesome where she instructs Kana how to ride you properly. Group sex scenes suddenly escalate into full-on multiple penetration with demons while you watch, and the game doesn’t shy away from showing your character getting hard from that. The weirdest part is how it will jump from “serious” talk about protecting Autumn City and fighting terrorists to a goofy ahegao close-up during vaginal and anal combo play, like the scriptwriter got distracted by Pornhub tabs halfway. I kept thinking of “The Monk” by Lewis, all that religious guilt and temptation stuff, except here the confession booth is a haystack and the punishment is another blowjob. The combat and adventure parts are there mostly to justify why you keep jumping into new worlds full of excuses for sex, but sometimes they actually land a cool line or magic effect and you forget for a second this is mainly about watching your waifu get fucked in every possible way, with or without you. Then the next scene loads, Kana is drooling around a cock again, and the illusion politely dies.

New city, new school, and your first big decision is basically “study or jerk off while spying through somebody’s window.” That’s the kind of vibe this game has, and honestly it works way too well. You show up in this kinda normal-looking academy town, but everybody is obsessed with this card game that is clearly not balanced, not healthy, and definitely not safe for a school environment. One minute you’re trying to pass a boring class, next minute you’re locked into a turn based fight where you’re trying to outplay some smug bastard while also getting distracted by the fact that his mom has her tits spilling out of a blouse that should not pass any dress code ever made. The whole “Battles of Mythria” thing is like if Yu-Gi-Oh watched too much porn and decided clothes are optional while dueling. You sit there thinking about card synergies and suddenly the reward screen is a girl with a big ass bending over your desk, animated just enough that your brain goes “ok, yeah, I’m staying.”

The sex stuff is slow-burn and then somehow also not at all. You start with these teasing moments that feel like accidents: your hand “accidentally” landing on a thigh in the library, a MILF teacher leaning in a bit too close so your face is basically buried in her cleavage, brushing past a girl in the corridor and feeling way more than you should. The game loves voyeurism. A lot. You peek through cracked doors, watch a classmate masturbating on her bed while pretending you’re looking for a lost book, see a shower silhouette where the tits are just detailed enough that you pause your Spotify to focus. Sometimes it lets you decide: jerk off quietly right there with your mouse hand doing double duty, or save the tension for later so maybe she “catches” you another day and you end up with a handjob under a desk instead. And when a blowjob scene hits, it doesn’t just show it, it lingers. The lips move, saliva strings, her head rhythm matches the text boxes popping, and you forget there was supposed to be any kind of “plot mystery” in this town at all. The best part is when a card battle goes wrong, you lose, and the punishment is her pinning you down, pressing those huge tits into your face and groping you like you’re the prize. The worst part is the tiny hover tooltips in combat that flicker when you move the cursor too fast and now I’m mad thinking about it again because I kept misclicking like an idiot and skipping turns while half hard. Anyway, the art is this weird mix of clean 2D CG and clearly AI-touched details, so sometimes a nipple looks too perfect for a human hand and sometimes a hand looks like it’s almost grabbing three boobs at once, and somehow that makes it hotter. It’s messy, horny, and just serious enough that you pretend you’re here for the adventure, while your real “strategy” is figuring out which girl to push from teasing and groping into that scene where she drops to her knees in a quiet corner of the school and takes you in her mouth like you’re the rarest card in the deck.

In my spreadsheets this thing looks like a total outlier. Every month I track genre tags from F95 and itch with some janky Python, and you can literally see this spike where “teasing + sci‑fi + humiliation + milf” starts overlapping with “investigation adventure”. That cluster used to be basically zero. Now there’s this weird nebula of games where the main mechanic is “solve the case with your tits”. This one sits right in the center of that mess. You play a young investigator dumped into a grim, gothic far future city, but nobody gave her proper gear, so her skill tree is basically: tongue, fingers, thighs, and a very low shame stat. First screen I walked into the church district, clicked a random suspicious guard, and suddenly the dialogue tree shifted from normal questions to “offer him a better view”. Chose it, camera framed her ass while she leans forward, pretending to search him, and his suspicion bar actually dropped because he was too busy staring. It’s stupid and hot at the same time, which is kind of the whole game.

The loop feels like someone glued together a point and click detective game with a slow corruption porn comic. You poke around the city map, find traces of the missing officials, and every clue is guarded by people who want something from her body. Not always full-on sex. Sometimes it’s just “take off your armor plates one by one” or “sit on his lap while he explains cult symbols”. The stripping scenes are animated just enough that you can see her hesitate, then keep going, robe slipping, boobs bouncing a little too much for anything standard issue. In one quest I had to get fingerprints from a suspected cultist nun. Expected the usual interrogation, got a “body search” mini-event where she lets the nun grope under her clothes “for contraband”. There’s this nice little moment where the protagonist pretends to complain, cheeks red, but you can tell she’s pressing closer instead of pulling away. The game keeps doing that: pretending it is about duty, while camera focuses on how wet her panties are when she has to “prove her devotion” to some monster-shaped relic. Also the interface is slightly annoying, tiny icons for inventory that you keep misclicking, but then you drag a relic on her body by accident and trigger a possession scene where tentacle shadows slip into her and make her masturbate on the altar while she’s still trying to ask questions about the case. So bug or feature, no idea, I just logged it mentally as “unexpected KPI of hand movement per minute”.

From data side, the funniest part is how many archetypes they cram into one woman. Statistically, games pick one: either cute rookie investigator or heavy milf with giant tits. Here she starts like a normal rookie, then the way the art exaggerates her body in each new outfit, by midpoint she basically turned into the office milf of the Inquisition. Big ass wrapped in pseudo‑holy straps, huge boobs squeezed into uniforms two sizes too small, and every lesbian encounter leans into that. There is one alley segment where a female cultist corners her, forces her to strip under threat of “summoning the beast”, but instead just spreads her on some cold machinery and eats her out while mocking how quickly she’s moaning for a woman she just met. It is half romance, half humiliation, and the dialogue is cheesy as hell, like fanfic written on a phone during commute, which somehow works better in porn than in normal games. You get combat segments too, but they are almost like foreplay that failed: lose a fight, and she gets pinned, fondled, maybe turned into a puppet for a while so the thing inside her can make her flash crowds in the market square. Win the fight, she still ends up rubbing herself off alone in a dark corridor, frustrated, fingers buried deep while she mumbles about “staying focused on the mission” and clearly does not. I actually wanted one clean, non-sexual interrogation, just to see how it feels, but the game keeps pushing her into situations where using her brain is the last resort, and her body has a much faster cooldown. Honestly, my notes are a mess, but the trend line is simple: every choice slowly turns her investigation into a public kink show, and the city reacts, stares, grabs, worships, laughs. Not very subtle, not very polite, but my charts say people are clearly into this filthy mix right now.

You die on a shitty first date and wake up staring at Rias’ tits. That’s basically the tone right away. No long build up, no “oh no what happened to me”, just you flat on your back, her in that tight outfit, looking down like she bought you on discount and is not sure if the product is broken or just horny. And guess what, you now belong to her and her little devil harem, which is honestly the most honest contract I’ve seen in a while.

The fun part is how the game treats the High School DxD cast. Rias is pure power fantasy and also total brat. One scene she sits on your lap, pushes your face in her boobs, calls you her “pet project”, and later acts like she did you a big favor by letting you cum on her stomach instead of just her hand. Akeno shows up like a walking BDSM quiz: “Question one, how much electricity can your balls take?” and then giggles like it’s afternoon tea. The teasing is constant. They drag you through the school halls in that classic uniform vibe, Asia bumping into you, apologizing with her big soft chest pressed in your face while Rias watches with this lazy smile, like she’s checking if you’ll stay loyal or just melt. Then you blink and suddenly Miki is pinning you to the couch, hips grinding, acting like “oh, I’m just helping Rias break you in.” There is a scene with toys that actually surprised me: Akeno pushing a vibrator along your shaft while Rias is sitting a bit away, legs crossed, pretending she’s only here to supervise, but her panties are getting wet and you can see the 3D jiggle when she moves wrong for half a second. On the other side you have Raynare and the others popping in with that monster girl edge, wings, claws, that cruel smile. Kalawarna treats you like office property: titfuck as a “performance review”, stroking your cock with those heavy boobs, asking “Are you loyal to your mistress?” while you’re trying not to blow early, because the game actually lets you fail that scene if you mess the timing. Which is funny and annoying at same time.

Some of the humor hits really hard. Like Asia walking in on Akeno tying you up, then trying to “help” by joining, but she only knows sweet missionary, so the whole thing turns into this bizarre combo of soft, loving vaginal sex from one side and cruel female domination from the other. The animated bits are honestly the best thing here. Rias bouncing slowly while riding you, red hair falling over your chest, then suddenly she leans forward and whispers something stupid like “You’re only alive because I wanted a toy” and you’re like, okay, step on me more. The camera sometimes lingers too long on feet for no reason, which is weird but also kind of on brand for DxD degeneracy. There is one scene with Mittelt where she pretends to be all innocent and then uses a toy on you with this little smug grin, and the only thing I hated is that it ended right when it got really nasty. Also, small complaint: they make you run around the school for dialogue triggers a bit too much when honestly I just want Rias to choke me with her thighs again. The adventure parts are there, clicking around, choosing who to serve first, but my brain kept going back to Akeno’s “quiz” and that one time Tsubasa just silently grinds on you in the clubroom like it’s no big deal. It’s messy, horny, sometimes stupid in a good way, and somehow the fact you died on a date fades away under a pile of big asses, bigger tits, and very smug devils who know exactly how much control they have over your dick.
