Caelus here is not the soft idiot from canon. The game basically asks, "What if the Trailblazer actually used all that cosmic bullshit to do the one thing everyone writes in fanfic but Hoyoverse pretends doesn’t exist?" and then never pulls back. Nanook is not some gloomy destruction god, he is straight up horny cosmic troll, like a drunk Archive of Our Own tag come to life. Plot is thin in a good way: every excuse to bend another Star Rail girl, and sometimes literally, into whatever shape your pervy little brain asked for the first time you saw her on a limited banner and thought “yeah I’d roll on that.”

What works weirdly well is how the game treats the whole “canon vs fanon” thing. Half the scenes feel like they were ripped straight from those long smut fics where the author clearly has a spreadsheet for everyone’s kinks. You know those 70k word monsters that start “slow burn” and then chapter 3 is already double penetration and mind control? Same energy here. One minute you are talking about Aeons and Paths, next minute Nanook just snaps reality and suddenly a proud Valkyrie type is on her knees giving this messy, noisy blowjob that would get a Twitch VOD nuked on sight. Then the scene pretends like nothing happened and jumps back to sci fi chatter. It feels wrong in a fun way. Or maybe in a stupid way. I liked it anyway.

The sex itself hits pretty much every checkbox people keep sneaking into tags: sloppy oral that really leans into the sounds, handjobs with way too much focus on fingers and precum, anal scenes where the camera insists on hanging on that first push a bit too long, and then stuff like footjobs that come out of nowhere. I mean it, you are casually abusing some broken mind controlled girl for exhibition in a public corridor, and suddenly she is using her feet like it is the most natural thing in the galaxy, with Nanook commenting in your head like a hentai Reddit thread. It is over the top and sometimes kind of dumb, but in a charming “this is clearly made by a guy who knows every Honkai subtag on Rule34.xxx” sort of way. The harem idea is full power, too. Caelus walks around like the universe itself is his brothel, and the girls, even when they resist at first, end up folded into this obedient, fucked-out collection entirely under his control. The mind control is not subtle. He rewrites them to love being toys, to show off outside with clothes barely hanging on, to beg him to use every hole in the worst moments, during missions, in front of cameras, whatever. And yet in the middle of all that excess, I got really annoyed that one small VFX on a cumshot looked like cheap soap. It bothered me the whole time and yeah, the game never fixes it.

What surprised me is how casually the game mixes sci fi nonsense and raw filth. You get “superpowers” here but not for saving worlds. Caelus uses cosmic energy to freeze time just to keep a girl’s mouth wrapped around his cock at the perfect angle, or to hold her asshole open while he decides if he wants to go back to her pussy or not. Sometimes reality bends so hard two girls exist in the same “moment” giving alternate versions of the same scene, one obedient, one still fighting, and you can flip your attention back and forth like changing tabs in Chrome. It sounds fancy, but in practice you are just clicking through dialogue while the game finds new ways to show spit, tears, ruined makeup and gaping. There is this one exhibition bit where a character is pretended to be fully in charge in front of a crowd, proper captain pose, and then in the next “layer” she is actually riding Caelus, forced to keep a perfect public speech while getting filled and emptied again and again. It is clever. Or maybe it is trash. Kind of both. Fantasy fans will notice half the lore is slightly off too. Some names are wrong, affiliations twisted, like the developer half remembered wiki pages and then said “eh, who cares, she is naked now.” Honestly, they were right.

If you ever read a “what if the Stellaron messed with their libido instead of destiny” fic and thought the author chickened out before the real filth, this is that same story but the brakes got removed, burned, and then fucked.

Game hits you in a funny soft spot right away: you’re this dude sneaking out of engineering into art like it’s some kind of perverted witness protection program. That feeling when you pretend to be “normal” nerd and all you really wanna do is draw pretty boys with stockings and girls with hard cocks sitting on your face? Yeah, they bottled that. Classrooms feel more like stages than actual school, every desk and easel is just a possible place to bend someone over. I kept thinking “this is exactly the kind of college I wish I fucked up my life in.”

What really got me is how erotic the whole art thing becomes. Not just sex slapped on top of story. You’re sketching, they’re posing, and slowly the poses stop being safe. A “tasteful nude study” turns into “can you open your legs more, I need to see the angle of your… spine.” There is this one moment where the childhood friend thinks she’s helping you “practice anatomy” and suddenly she is on her knees, hand around your cock, asking if she is holding it right for the drawing. Of course you don’t draw. Of course you shove that sketchbook aside and let her slobber on you. And the game actually makes the scene feel like it came from your little pervert artist brain, not from a porn script copy paste. Animations are not perfect but they wiggle just enough. Hip movement, fingers sliding, tongue flexing over the tip during oral. I watched a simple handjob way too long just because of how her thumb kept teasing that one spot like she was bored and mean at the same time. Tiny detail, but I couldn’t stop staring.

Then there is the femboys and traps and futa stuff that kinda crawls up on you. At first you look at this “cute boy” in class and think “ah, standard pretty twink, I know this gacha.” Then the game pulls the shirt a bit higher, the skirt a bit shorter, and you notice the outline that is not really hiding anything. There is an exhibitionism scene where this soft, shy “guy” is pushed into posing for you after hours in the empty studio, naked except for a collar, and instead of being embarrassed you are the one sweating, trying to keep the brush still while his cock twitches every time you step closer. It feels cruel and kind at the same time. Humiliation and praise mixing like bad cocktails. And when the power flips, when you are the one on your knees under the table, sucking while someone explains color theory above you, it hits that heavy fetish vibe hard. The game doesn’t bother to explain why the protagonist suddenly agrees to be choked with a belt during anal, it just puts you there, cheeks pressed against cold floor, someone’s foot on your head, and your brain goes “yeah, okay, this makes sense actually.”

I also liked that domination is not stuck in one lane. One scene you are pinning a smaller boy against the lockers, hand under his skirt, groping his ass until he whimpers and pushes back, pretending he doesn’t like it. Next, a tall girl with “I own this place” eyes drags you into the storage room, orders you to take out your cock and strokes you so slow it feels like torture, spitting on it, smirking when you leak all over her fingers. She makes you hold the door while she rides you, whispering that if anyone hears, it’s your fault. The game jumps between male and female domination like it can’t decide what gets you more: being used or using someone. Sometimes it even blends, like that threesome where a futa girl fucks you from behind while you jerk off a femboy in front, your body just a bridge between two horny monsters. You feel like art supplies. Like a brush and canvas at the same time.

I wish the dialogue was less “anime horny” in a few scenes, it leans a bit too much into cheesy lines that no real person would say with their mouth full of dick, but then there is this one brutal little bdsm moment where someone tells you “you’re only good for making me cum” and it cuts deep enough to forget all the cheesy stuff. Some camera angles feel a bit stiff, then a random shot of fingers spreading slick cheeks or lips grazing the tip in close-up suddenly looks like something straight from a high quality clip I’d save on my phone next to my secret Pinterest board of ropes and stockings. The whole thing feels like a messy sketchbook full of porn doodles that someone grew into a real game: uneven, kind of clumsy, but dripping with ideas. Makes you wanna grab your tablet, open Procreate, and start drawing collars and blushing traps until your hand gets tired for a very different reason. Dare to open it in a quiet room and see how long you last before alt-tabbing to Pornhub “for research.”
