RuleUniverse feels like someone mashed Dragon Ball fanfiction, horny Twitter art and a half-finished Ren’Py project, then accidentally made it kind of addictive. You start as this lonely overachiever kid that reads like every shonen protagonist in history, then a demon scientist pops up and says, “hey, let’s stuff your body with DNA from the strongest fighters in the universe, what could go wrong.” It’s delightfully stupid in that fanfic way, but precisely because of that, it works. The game knows it’s a parody, it doesn’t try to pretend it’s “deep”, and then it suddenly throws in a line about destiny or guiding the universe and you’re like… alright, Toriyama-with-horny-mods, calm down.

The real fun is how transparently it worships its women. Bulma, Chi-Chi, Android 18, that whole legendary boob-and-ass pantheon is here, clearly shaped by someone who grew up pausing VHS at the worst places. The models are 3D and exaggerated as hell: huge tits, fat asses, those shiny anime lips that just scream “she’s going to suck him off in like two clicks.” Animated scenes actually move, not just two stiff characters rubbing like broken Sims; you get thrusting, jiggling, drool, that soft spit string when you pull out from a blowjob, all the little pervy details that tell you the dev really wanted this for themselves first. One moment you’re doing basic combat with ki blasts and energy auras, the next you’re balls-deep in Bulma in a lab, with wires and science junk in the background like that somehow makes it ethical. And the combat’s funny: it pretends to be serious, but all you’re thinking is “okay, how many fights until I unlock the next sex scene with Android 18.” Sometimes the sandbox part feels less like a “world” and more like a small playground with a fence around it, but the loops of walking around, clicking, triggering small events, slowly unlocking more lewd stuff… it scratched that same spot as old flash games I used to sneak at school on shitty browsers.

I kinda love how messy it is. The romance tries to act sentimental for a second, then five lines later you’re face-fucking a milf with magic powers while she moans like someone recorded it in a bathroom on a cheap mic. Dialog swings from “I will guide the universe” to “fuck me harder” without the slightest shame. Exploration is simple, a little repetitive, but I still kept wandering, poking every corner hoping there’s a hidden event where Chi-Chi finally snaps and rides the protagonist like he’s the last Saiyan on earth. Some text sounds like it was written at midnight by a dude half-remembering DBZ arcs from YouTube AMVs, which, honestly, is the right energy. I do wish the world reacted more to what you do, like if you bang Bulma enough, Vegeta starts showing up mad or something, but I know that kind of feature is exactly the thing that stays in the dev’s “maybe later” notes forever. Still, when you’re watching Android 18 slowly drop to her knees after you save her in a fight and she rewards you with this sloppy, animated blowjob, with her tits barely contained and that quiet smug smile when she swallows, it hits the trashy, horny, teen-power-fantasy nerve in a very specific way. It’s not elegant. It’s not smart. It’s like a wet doujin turned half-game, half-daydream, and somehow that’s exactly why it sticks.

Warm sand under your back, that lazy dead-fish feeling after too much sun, and suddenly the whole world is just ass. Not metaphorical ass, not “thicc” like people spam in comments, but two animated legends grinding reality out of focus: Android 18 with her perfect ice-queen blonde vibe and Erza with that wild red hair that looks like it still smells like battle smoke and perfume. They are on the beach with you, but also not really “with” you, more like on you, around you, over you. The game starts in that half-dream state where you’re not sure if you passed out from heat or from scrolling too long on Pornhub. Then the screen settles, the loop hits, and you’re basically pinned there, face in the danger zone, while they twerk slow and teasing, asses so close you feel like your monitor might grow taste buds. It’s that kind of short, dirty fantasy that feels like someone took all the fanart from Reddit and boiled it down into one shameless anal-focused scene, no plot, no talking, just rhythm and skin and the sense that you somehow woke up in the middle of a crossover nobody had the right to make and everyone secretly wanted anyway.

There’s this weird magic in how nothing really “happens” and still everything is happening. Android 18 moves with that cold precision, like she calculated the exact angle where her booty will hover over your mouth, just out of reach, like she knows you’re useless here and enjoys it. Erza is the opposite, her ass movement feels more playful, almost chaotic, like she is the one who dragged 18 into this little beach sin-session and is now showing off, cheeks bouncing, sometimes almost clapping in your face, sometimes slowing down just enough that you catch yourself leaning forward at a screen like an idiot. The camera sits low, submissive, like you’re stuck in the sand while they use your head as their personal seat cushion. You get pussy flashes, that quick glimpse here and there when they shift position, a little pink flash that makes your brain glitch for a second, especially when it happens while they arch their backs and present fully, like “here, have this, but only for one frame, enjoy suffering.” Anal is the star though. Their butts are treated like holy objects, center stage, big, round, demanding, the way they tilt and spread just enough so your imagination fills all the gaps. It’s almost rude how short and looping it is. You just start syncing your breathing to Erza’s slow bounce, Android 18’s more measured grind, and then you realize this is it. No climax scene, no “next phase”, just you looping like a horny goldfish pressing replay, pretending your hand hasn’t already figured out the timing like a rhythm game.

That’s the thing that got me. It feels like a dirty little GIF you shouldn’t like as much as you do, but you keep it open in a small Chrome tab anyway, somewhere between Twitter and xVideos, letting it run while you do other stuff, then suddenly you’re staring again. The beach background is almost nothing, just light and sand and that lazy sea vibe, but somehow it adds to the fantasy of “sunburned pervert wakes up and two famous anime girls are using his face as furniture.” There’s no voice lines, no moans, no cheesy music trying to be sexy, only the animation doing the work, like those old Flash loops that used to live on sketchy sites, except cleaner and more focused on asses. At one point Erza leans forward just a tiny bit more and her red hair falls, covering half of 18 from your view, and that small moment stuck with me way more than it should, because it feels almost intimate, like you’re spying on something they’re doing for themselves, not for you. And yeah, it’s basically a glorified loop about booty and anal teasing, you’re not getting a deep gameplay session out of this, but sometimes that’s exactly what fries your brain in the nicest way: two iconic babes, one beach, your face in the wrong place and the right place at the same time, and nothing to do except watch them bounce until your wrist gives up or your browser starts lagging.

Lazuli is that kind of protagonist you usually see as a side joke in hentai: horny mad scientist, weird potions, zero moral brakes. Here she’s the center of everything, and the whole game just leans into that idea of “what if a futa alchemist decided the world is her test lab and every girl she likes is a guinea pig with tits.” The Cumcoction is her proud invention, but it behaves more like a jealous deity than a simple drug. One drop and a shy virgin trainer girl suddenly starts grinding on a table corner; a proud swordswoman wakes up from “just a drink” with hazy memories, cum leaking out of her ass, and a faint sense that she liked it way too much. The story keeps this strange mix of silly and fucked‑up: Lazuli talks about alchemy like a nerd who reads too many grimoires, but then she’s also the same maniac who will jerk off behind a curtain, whispering little comments while a corrupted Hinata worships her cock with both hands and mouth, drool everywhere, eyes shining with that brainwashed devotion hentai artists love so much. Scenes go from goofy experimentation to really mean stuff: blackmail with magically recorded voyeur footage, “accidental” sleep sex justified with bullshit pseudo‑science, and that slow corruption arc where proud heroines from worlds like Naruto, My Hero Academia, Dragon Ball, Fairy Tail, One Piece or Pokémon tumble down from “No, never” to “Fine, just my hand” to “Why does it feel empty when you pull out?” without even noticing how far they fell.

What makes it weirdly charming is how inconsistent Lazuli is as a character. One moment she’s doing an almost tender titfuck with someone like Nico Robin, clearly enjoying the shape of those big soft breasts, carefully smearing cum on them like she’s painting. Next moment she’s using transformation tricks so suddenly Serena or Nessa find themselves with a fat new cock between their legs, panic mixing with arousal while Lazuli explains in that smug voice how “temporary” it is, then pushes them into group sex anyway. The game uses that 2D and 3D mix in a dirty way: sometimes you get a short animated loop of a character like Erza or Android 18 taking anal, her ass bouncing and jiggling, and then it cuts back to static art for the aftermath, thick creampie dripping while Lazuli notes something in her research book. It feels like a porn lab notebook: handjob success rates, mind control side effects, level of groping tolerated before resistance drops. There are cute slices of perv life too, like Lazuli just watching Nami and Lillie masturbate separately under a subtle spell, legs shaking, completely unaware they’re being observed like experimental mice, or a harem scene where Kushina, Hinata and Sarada end up sharing the same futa cock, half from drugged lust, half from Lazuli’s shameless manipulation. The tone never fully decides if this is still “fun” corruption or already full damnation, and honestly that’s what keeps it interesting: you’re stuck in that sticky line where fantasy, mind control, blackmail, anal, vaginal, sleep sex, creampies, big tits, big asses, all blend together into one long, filthy project of turning every famous girl in anime into Lazuli’s personal property, catalogued, studied, and thoroughly fucked.
