Right now the fandom feels split pretty cleanly between Aventurine/Dr. Ratio and Aventurine/Sunday. The Ratio dynamic is the obvious one—intellectual sparring, high-stakes corporate intrigue, that whole 'mind games as foreplay' thing a lot of writers really nail. It's got this built-in tension from their canon power imbalance that makes for excellent slow-burn or outright hostile fics. The writing quality tends to be higher on average, maybe because the premise attracts people interested in dialogue and psychological maneuvering.
That said, Aventurine/Sunday has surged lately. It offers a completely different flavor: more aesthetic, often tinged with melancholy or secret pining, playing with themes of performance and sincerity. I've seen some fantastic AU takes that transplant them into different settings, like rival musicians or fantasy royalty, which really works for them. It's less about the verbal chess and more about the silent communication across a crowded room, which can be just as gripping if done well.
Honestly, I'd start with the Ratio pairing to get a feel for the character's core dynamics, then branch out to Sunday fics for variety. There's a small but solid stream of Aventurine/Reader insert stuff too if that's your jam, but the shipfics are where the most nuanced character exploration happens.

One thing I've noticed is that a lot of stories focus on the power imbalance as a core dynamic. Ratio is the scholar, driven by logic and a certain moral rigidity, while Aventurine operates on risk, charm, and opportunistic calculus. Fanworks often put them in high-stakes scenarios, like a heist or a diplomatic negotiation, just to watch their methodologies clash. It's less about romance right away and more about a fascinating intellectual duel. The tension comes from whether Ratio's principles will bend or if Aventurine's facades will crack under genuine scrutiny.
Some of the best fics I've read actually subvert the expected 'genius teaches gambler' trope. Instead, Aventurine's street-smart intuition and ability to read people sometimes outmaneuvers Ratio's book-smart deductions, which forces Ratio to confront the limits of pure academia. That reversal feels fresh. The dynamic evolves from antagonistic begrudging respect to something more layered, often through small, quiet moments of unexpected vulnerability from Aventurine that Ratio, against his better judgment, feels compelled to understand.

Honestly, if you're looking for Ratio and Aventurine crossovers specifically, the pickings are going to be slim. That's a pretty niche pairing even within the 'Honkai: Star Rail' fandom. I've had the most luck just doing a direct search on Archive of Our Own with the characters tagged; filtering by the 'Crossover' tag alongside those will get you anything that exists. The best-written piece I've found is actually a one-shot that throws them into a vintage noir AU, which is a weirdly perfect fit for their dynamic. You'll probably waste more time digging through generic Aventurine fics hoping for a Ratio cameo than you will actually reading.
Sometimes these ultra-specific cravings are better served by thinking laterally. I once read a great Stelle/Caelus fic that had Ratio and Aventurine as brilliantly characterized side characters with tons of tension—their dynamic was the highlight, even if the story wasn't technically about them. It's often the fics tagged with just one of them, where the other appears as a major secondary, that deliver the goods.

Ratio's whole thing is about proving people wrong through cold, hard evidence, while Aventurine thrives on chaotic, high-stakes gambling. So naturally, a ton of fics throw them into situations where their opposing methods clash—Ratio's trying to calculate the exact odds of a plan succeeding, and Aventurine's just shoved all the chips onto a single wild card, grinning like a maniac. The tension writes itself. You get a lot of 'enemies to reluctant allies' plots, or even full-blown 'enemies to lovers' where the intellectual friction turns into something else entirely.
I've seen a bunch of stories explore the idea of trust, or the lack thereof. Ratio would never trust a gamble, but he might start trusting the gambler, if that makes sense. The fics that really nail it are the ones where Aventurine's seemingly reckless bet pays off in a way Ratio's models couldn't predict, forcing him to re-evaluate everything. It's less about romance for me and more about that delicious, frustrating dynamic where they're both right and both wrong at the same time.
Some authors go for the 'mutual self-destruction' angle too, which is fun—two brilliant minds so obsessed with their own game they burn the whole table down together.

The whole Ratio x Aventurine dynamic just screams 'rivals forced to cooperate' to me, which opens up so many avenues. I'm a sucker for undercover missions where they have to pretend to be a couple—it's cliché but the tension writes itself. Like, they're infiltrating some high-stakes gambling den or corporate event, and the act starts blurring into something real halfway through.
I've seen a few fics play with the idea of one of them getting injured and the other having to patch them up, but it often feels rushed. Slowing that down, having them stuck in a safehouse for days with nothing but grudging conversation that slowly turns into something else? That's where the good stuff is. The bickering would be next level, but so would the quiet moments when they finally drop the act.
My favorite twist I read had Aventurine secretly funding Ratio's research for years, not out of charity but as a calculated investment, and Ratio finding out in the worst possible way. The emotional fallout was brutal but so satisfying.

I see their dynamic pop up a lot in fics that focus on power imbalances and transactional relationships. Writers seem fascinated by the inherent tension in their canon setup—one's a gambler who thrives on risk, the other's got this calculated, almost mineral-like steadiness. It sets up a natural push-pull. The best fics I've read don't just make it romantic; they dig into the weird intimacy of a deal, the unspoken trust needed when stakes are high.
Aventurine's flashy confidence against Ratio's reserved analysis creates perfect fodder for misunderstandings that slowly unravel into something deeper. I've seen a few AU fics where Ratio is a scientist and Aventurine a corporate raider, and the core dynamic stays intact even when the setting changes. That's how you know it's a pairing with legs—the archetypes clash in a way that's endlessly generative for conflict and, eventually, understanding.

I came across a few while browsing Tumblr, actually. Someone had a whole masterlist dedicated to 'Honkai: Star Rail' ships, and ratio/aventurine was tagged in there. The blog was called something like starlight-ships, but I'm not sure if it's still active. That might be a good place to start digging through their reblogs.
A lot of fic writers for that pairing seem to be on Twitter too, using the hashtag #Ratiorine. If you search that, you'll sometimes find threads where people exchange recommendations or snippets they're working on. It's a bit more scattered than a dedicated archive, but the community feel is nice.
I've noticed the ao3 tag isn't super populated yet, so you gotta rely on those fan-to-fan networks more than anything. You'll probably find a couple of decent oneshots buried in the general 'Honkai: Star Rail' fandom tag if you filter by both characters.
