Been scouring the web for LOONA and Beelzebub crossovers myself, and honestly, it's a weirdly specific niche. The overlap between K-pop girl group lore and a manga about a demon baby is thin, but that's what makes the finds so fun. The main hub is definitely Archive of Our Own. Use the tags for LOONA (K-pop) and 'Beelzebub (Manga & Anime)' together, and filter by kudos or comments.
Don't just stop there, though. Crossovers sometimes lurk in the general 'LOONA (K-pop)' or 'Anime & Manga Crossovers' tags without the other fandom tagged properly. I've found a couple of gems by searching for 'Beelzebub' and then browsing the author's bookmarks. Tumblr used to be better for this, but now it's more about finding rec lists. Check blogs that are deep into either fandom; they sometimes have old curated posts of 'rare crossovers you've never read'.
My favorite story in this pairing is 'Hell's Front Door,' which is a crack-treated-seriously fic where Olivia Hye ends up as Beel's temporary babysitter. The chaos is perfectly in character for both sides.
Another place I sometimes lurk is the /r/LOONA or /r/kpopfanfiction subreddits, but you have to ask directly. Threads don't stay up long, but if you post a request, someone usually DMs you a link. The key is persistence and being willing to dig through a lot of unrelated stuff.

Man, this is an oddly specific crossover I've never considered but now I'm weirdly intrigued. The core dynamic is a celestial bureaucracy sweetheart versus the lord of the hellish executive suite. You could absolutely run with a rom-com office AU; imagine Beelzebub, head of Acquisitions & Temptations, constantly having their meticulously filed sin reports flagged for 'insufficient grace' by Loona from Heavenly Compliance.
But where it gets really interesting is flipping the expected genres. Instead of fluffy romance, lean into a supernatural thriller. Loona uncovers a plot in heaven that requires a forbidden alliance with hell's most pragmatic ruler. The tension isn't just will-they-won't-they, it's the constant, nail-biting risk of divine retribution or infernal betrayal. The bureaucratic setting becomes a cage for a much darker game of cosmic espionage.
Honestly, the 'enemies-to-lovers' arc feels almost too obvious here. The real potential might be in a tragedy or a bittersweet philosophical drama. Their respective natures might be fundamentally incompatible, leading to a story less about romance and more about the poignant, impossible understanding between two beings on opposite sides of an eternal fence. That could hit harder than any happy ending.

I stumbled upon this gem called 'Devil's Cradle' on AO3, and it absolutely wrecked me in the best way. The author explores Baby Beel's uncontrollable demonic energy surges, which force Oga and Hilda into constant proximity to stabilize him. The tension is chef's kiss—Hilda's pride clashes with Oga's stubbornness, but they slowly cave to shared vulnerability. The fic nails their dynamic: Hilda’s icy exterior melts when Oga accidentally shields her from Beel’s tantrum-induced shockwaves, and their banter turns tender.
Another standout is 'Hunger Pangs,' where Beel’s growth spurts drain Oga’s strength, forcing Hilda to step in as a caretaker. The irony of the demon maid fussing over a human is hilarious yet poignant. The fic’s climax—where Oga collapses mid-fight and Hilda carries him bridal-style—had me screaming into my pillow. The author weaves in subtle lore from the manga, like how Beel’s powers resonate with Hilda’s suppressed emotions, making their bond feel inevitable.

I recently stumbled upon this gem titled 'Hellfire and Honey' on AO3, and it’s everything I didn’t know I needed for Oga and Hilda. The author nails the enemies-to-lovers trope by weaving in their fierce rivalry with moments of reluctant vulnerability. The pacing is perfect—slow burns aren’t usually my thing, but the tension here is electric. Oga’s gruff exterior softening around Hilda’s sharp wit feels organic, not forced.
The fic also dives into their shared history with the demon world, adding layers to their conflict. There’s a scene where Hilda gets injured protecting Baby Beel, and Oga’s panic is chef’s kiss. The dialogue crackles with their usual banter, but there’s this underlying warmth that creeps in. If you love angst with a payoff, this one’s a must-read.

I recently stumbled upon a gem titled 'Devil's Cradle' on AO3 that explores Oga's emotional turmoil in a way I haven't seen before. The author nails his internal struggle between teenage rebellion and unexpected paternal instincts. There's a raw scene where Oga skips a fight to comfort Baby Beel during a thunderstorm, and his voice cracks—it shattered me.
The fic also weaves in subtle parallels between Oga's absentee father and his own fear of failing Beel. The writing style is gritty yet tender, with street slang that makes Oga's POV authentic. Another standout is 'Hell's Diaper Bag,' which uses humor to mask deeper themes. Oga's panic attacks when Beel gets sick feel painfully real, showing how love reshapes his tough-guy persona.

Moxxie and Beelzebub? That's a surprisingly specific corner of the 'Helluva Boss' fandom. I mean, we've barely seen them interact on screen, but that's exactly where fanfic thrives, right? The dynamic potential is wild. You've got Moxxie, this repressed, anxious, rule-following imp with a core of hidden competence, and Beelzebub, the absolute chaotic neutral force of hedonistic gluttony and raw power. It's a classic opposites-attract setup, but the 'opposite' here is cosmic.
For the best 'ships,' I'd say look beyond the obvious romantic fling. The most interesting fics I've read treat it as a bizarre mentorship or a mutually exploitative partnership. Beelzebub might find Moxxie's fastidiousness weirdly entertaining, like a pet that organizes your flies, and Moxxie could be trying to 'manage' a Sin for his own twisted ambitions. I stumbled on a fic called 'By the Book' that nailed this—Moxxie was trying to apply corporate bureaucracy to the Gluttony Ring's operations, and Beez was just messing with him nonstop. The tension was less 'will they kiss' and more 'will Moxxie have a nervous breakdown or actually achieve something.' It's a different flavor, but it feels more true to the characters than forcing instant romance.

Any story that actually puts Moxxie and Beelzebub in a room together has to start with their core dynamic: hierarchy. She's a literal queen, he's a mob accountant with a fragile ego. The most rewarding tropes play with that power imbalance, but not in the way you'd think. Enemies to Lovers is the obvious one, but skip the shouting matches—their conflict would be bureaucratic. A fic where he has to audit the Greed Ring's finances and uncovers something she wants buried is perfect. The tension comes from her trying to intimidate him and him responding with a perfectly cited bylaw.
Slow burn is non-negotiable. A one-night stand would feel cheap. The appeal is the glacial thaw of mutual professional respect into something else. Maybe he's the only one in Hell who files reports correctly. I once read a crossover where Moxxie was a demonic tax auditor and Beelzebub was his biggest client; the romance snuck up on them through coded footnotes in expense reports. It was weirdly hot.
Also, don't forget the 'Fish out of Water' angle for Moxxie. Stories where he's forced to navigate the high-stakes politics of the upper rings, with Beelzebub as his reluctant guide—or amused observer—add a layer of comedy and pathos you don't get with more conventional pairings. It lets him be competent in his own niche while highlighting how utterly out of his depth he is socially, which she'd find fascinating.

I've stumbled upon some really touching 'Beelzebub' fanfics that dive deep into Baby Beel and Oga's relationship, but with a romantic twist. The best ones often explore how Oga's rough exterior hides his genuine care for Beel, and how that dynamic could evolve into something more. Authors love to play with the idea of Oga struggling between his duty as a caretaker and unexpected feelings. Some fics even have Baby Beel growing up faster due to demonic traits, adding layers to their bond.
One standout is 'Demon’s Heart,' where Oga’s protectiveness turns into longing as Beel matures. The fic handles the transition from familial to romantic with surprising grace, avoiding clichés. Another, 'Thicker Than Blood,' frames their connection as a slow burn, with Oga denying his emotions until a crisis forces him to confront them. The tension in these stories is palpable, and the emotional payoff is worth the wait.

Honestly, it's a pairing that flips the whole dynamic of 'Helluva Boss' on its head, doesn't it? You've got this complete departure from the established chaos, Moxxie's structured anxiety clashing with Beelzebub's hedonistic chaos. It forces the writer to think about power imbalances in a totally different way. Like, he's a lowly imp and she's a literal Sin. The tension isn't just romantic, it's societal. Does she pull him up, or does he get consumed? I've seen fics where it's a political marriage nightmare, and others where it's this weirdly tender mentorship that curdles into something else.
It opens up lore diving too. Beelzebub's realm gives you so much more to play with than just I.M.P.'s office. Gluttony as a setting is visually wild—endless feasts, grotesque beauty. Moxxie's meticulousness in that environment is comedy gold, but it can also be tragic. He's trying to impose order in a dimension literally built on excess. The stories that work best for me aren't the pure smut ones, but the ones that really sit with that dissonance and let it simmer. It's less 'will they/won't they' and more 'how on earth would this even function for a week?'
That fundamental incompatibility is where all the juice is, I think. It makes every interaction high-stakes.

Those crossover pairings come up more than you'd think once you start looking in certain corners. The main hub for anything LOONA-related in fanfic is Archive of Our Own – the tagging system is your best friend there. You want to search for the 'LOONA (K-Pop Group)' fandom tag and then filter by the 'Beelzebub (Manga)' fandom tag. That'll get you the actual crossovers.
But honestly, a lot of the good stuff happens under more specific character tags, not just the broad fandom ones. People might tag 'Heejin (LOONA)/Beelzebub' or even just write 'Loona' from 'Helluva Boss' by mistake, so you have to be a bit patient. I found a surprisingly angsty longfic last year that had ViVi as a fallen angel getting tangled up with Beel's whole demon lord politics thing.
Wattpad has some, but the quality varies wildly and the tagging is chaotic. I'd stick to AO3 for consistency. Tumblr blogs sometimes promote their own work or reccommendations, searching 'loona beelzebub fanart' might lead you to a fic link in the description. It's a niche within a niche, so you have to dig.
