Trying to find crossovers for those two specifically is like searching for a rare pair in a tiny fandom within a fandom. 'The Disastrous Life of Saiki K.' isn't a massive crossover hub to begin with, and Toritsuka's a supporting character. So the pool is super limited.
Your best bet isn't going to be a dedicated rec list, but scouring Ao3 and Fanfiction.net with the right tags. Filter for crossovers, include both characters, and maybe add the fandom you want it crossed with. I've had luck with 'Jujutsu Kaisen' or 'Mob Psycho 100' as companion fandoms—they share that supernatural-slice-of-life-comedy vibe that makes the character voices easier to blend. You might get one or two good ones in a sea of Saiki/Kaido or Saiki/Aren fics.
Honestly, sometimes you gotta write the fic you want to read. The dynamic of a genuine psychic constantly annoyed by a horny, ghost-using fraud is comedy gold waiting to happen.

I'm not sure there's a single 'best' list anyone can give, but I keep going back to this one story, 'Anomalous Interference,' on AO3. It's set after the manga ends, with Toritsuka trying to get his spirit medium business off the ground and Saiki reluctantly getting dragged in because Toritsuka keeps attracting psychic phenomena that are too powerful for him to handle alone. The slow-burn of Saiki's begrudging tolerance turning into something like partnership feels very true to character.
What I love is that it doesn't force a romance. It's more about two people who, on paper, should never interact, building a weirdly functional dynamic out of mutual annoyance and occasional necessity. The author nails Saiki's deadpan internal monologue and Toritsuka's persistent, lecherous optimism. It's less about shipping and more about exploring what a friendship between these two would actually look like if Saiki ever stopped running away. The ending leaves it ambiguous, which fits them perfectly.

Man, I feel this search in my soul. Finding that specific 'oh no he's hot' energy between Saiki and Teruhashi is a whole mood, but it can be scattered. AO3 is my usual haunt—their tagging system is a lifesaver. If you filter by the 'The Disastrous Life of Saiki K.' fandom and then the pairing 'Kusuo Saiki/Kokomi Teruhashi,' you'll get a solid list. Adding the 'Romantic Comedy' or 'Fluff' tags helps narrow it down. The real trick is sorting by kudos or bookmarks; some of the older gems get buried otherwise.
Don't sleep on FanFiction.net either, though the tagging is messier. You gotta use the search function and wade through some crossovers. I found a hilarious one there called 'Unspoken Agreement' where Teruhashi's 'oh poor me' act accidentally works on Saiki for once, and his internal monologue is peak comedy. Wattpad has a different vibe—more modern AUs, like coffee shop or university settings, if that's your thing. Just be prepared to sift through a lot of unfinished works.
The dynamic is perfect for rom-com, right? Teruhashi's desperate need for attention versus Saiki's desperate need for anonymity creates this fantastic push-pull. The best fics capture that—Teruhashi scheming her cutest schemes, Saiki being utterly deadpan but maybe, just maybe, noticing her a tiny bit more than he lets on. I live for the moments where his psychic powers backfire because of her sheer, universe-bending luck.

I've noticed this pairing tends to get stuck in a specific rut. Most fics feel like they're just rehashing the same dynamic where Saiki is exasperated but secretly fond and Toritsuka is a hopelessly persistent nuisance. That 'grumpy/sunshine' template gets old after you've read twenty variations. I'd love to see someone really dig into the genuine moral chasm between them—Saiki's rigid, self-imposed ethical code versus Toritsuka's complete lack of one when it comes to using his powers. That's where the real tension is, not just in whether Saiki will finally admit he tolerates the guy.
There's also a weird avoidance of how Toritsuka's perversion actually functions as a character flaw, not just a cute quirk. In canon, it's genuinely repulsive to other characters. Exploring that from Saiki's telepathic perspective could be horrifyingly intimate and deeply uncomfortable, which would be a fascinating angle instead of the usual fluff. Most stories sand down the edges until they're just another odd couple, and that feels like a missed opportunity for something darker and more interesting.

It's hard to top a twist that recontextualizes their entire dynamic from the jump. I read one once where the twist was that the "psychic connection" Saiki always groaned about wasn't just annoyance—it was a genuine, two-way empathic link Toritsuka accidentally forged during one of his usual attempts to peek into Saiki's mind. The fic built it up like Saiki was just being his usual grumpy self, but the reveal was that he was actually constantly feeling the emotional fallout of Toritsuka's own loneliness and self-loathing, which he'd buried under all that pervy bravado. That hit different.
Suddenly Saiki's irritation wasn't just about the nuisance; it was this unbearable intimacy forced on someone who values his solitude above all else, while also being unable to ignore the very real pain of the person he acts like he can't stand. The twist didn't change their banter, but it gave every sarcastic comment Saiki made a layer of reluctant, pissed-off caretaking. It made their ending feel earned, not saccharine.

Ah, I've scrolled through a lot of Saiki x Toritsuka stuff, and honestly, most of it leans hard into the comedy already present in 'The Disastrous Life of Saiki K.' The dynamic is inherently funny—Saiki's deadpan annoyance versus Toritsuka's desperate, pervy enthusiasm. The fics that nail it don't try to force a dramatic romance; they just let those personalities clash.
I remember one where Toritsuka tries to use his spirit medium powers to set up a 'perfect date' by possessing Saiki's family, and Saiki just spends the entire time internally monologuing about the sheer inconvenience while subtly sabotaging it with his own powers. The humor came from the escalating absurdity and Saiki's increasingly creative ways to express 'leave me alone.' Another good one was a modern AU where Toritsuka kept trying to get Saiki to join his fake ghost-hunting YouTube channel, with Saiki replying entirely via telepathy to Toritsuka's phone. The mismatch in energy is the whole joke.
Honestly, the best comedic fics for this pairing feel like extended, slightly more chaotic episodes of the show. They work because the writers understand the original tone.

I feel like I'm the last person to figure out Ao3 has the highest concentration of Saiki/teruhashi fics? They're really into the deep psychological stuff there. Like I saw a multi-chapter where she realizes his apathy is a shield because he can actually read minds and feels overwhelmed by everyone's expectations, and he starts to value her genuine if misguided affection. It's pretty complex character work sometimes.
On fanfiction.net you'll still find a lot of the older, more tropey stuff—"locked in the storage closet" kind of plots. It's comforting in a predictable way, but the tagging system on archive of our own makes finding specific dynamics way easier. I've also come across some on Pixiv if you're up for navigating the tags in Japanese, though that's more for art with accompanying short stories.
