Man, this takes me back. AO3 is the undisputed king for that ship, no contest. The tagging system alone makes it worth it—you can filter for exactly what you crave, whether it's a slow-burn pining fic or a fast-paced action romance where they're still rivals. Wattpad has a younger crowd, so the plots can skew more towards high school AUs or soulmate tropes, which isn't my personal jam but I see the appeal. Tumblr is weirdly good for finding shorter, moodier pieces and headcanon threads that feel like little character studies, though you have to dig through reblogs. I'd actually advise against Fanfiction.net for this specific pairing; the interface feels ancient and the tagging is nonexistent, so you're basically scrolling blind. A lot of the classic older fics migrated to AO3 anyway.
The real hidden gem, if you're willing to put in the work, is checking out authors' personal Twitter or Carrd pages. Some of the best KiriBaku writers I follow will post snippets, threadfics, or even link to their works on lesser-known sites like Pillowfort. The community feel there is different—more focused on WIPs and interactive asks. Just don't get sucked into the black hole of quote tweets and drama; stick to the creative corners. For sheer volume and quality control, AO3 is your one-stop shop, but the ecosystem around this ship is surprisingly spread out if you know where to poke around.

AO3 absolutely dominates this particular pairing. Their tagging system is unparalleled—you can filter for exactly the dynamic you want, whether it's established relationship, slow burn, hurt/comfort, or the specific flavor of mutual pining where Kirishima is the sunshine trying to thaw Bakugou's perpetual winter. I've found stuff there I've never seen mirrored anywhere else. The quality bar tends to be higher too, maybe because writers invest more time when they're tagging for a proper archive.
Having said that, I'd be remiss not to mention the old-school vibes of Fanfiction.net. The search function is a nightmare, no lie, but there's a certain charm in trawling through pages. You'll stumble upon fics from 2016, 2017, the golden age of the ship's rise, that have this raw, earnest energy AO3 sometimes polishes away. It's like digging in an archaeological site.

Honestly, most of the really intense stuff for that ship tends to migrate off the bigger public archives after a while. AO3 is still the central hub for tagging and discovering it, hands down. The 'Bakugou Katsuki/Kirishima Eijirou' tag there is massive, and the filters let you narrow down to Explicit ratings and specific kinks or tropes super easily. I've found some absolute masterpieces hiding in plain sight there.
That said, a lot of writers, especially for more graphic or niche kink content, feel a bit exposed on AO3 and cross-post to Tumblr blogs or private Discords. It's more of a word-of-mouth scene; you follow an author you like on AO3, check their profile link, and it might lead you to their Carrd with links to a private Twitter or a Discord server where they drop their 'darker' or more experimental stuff. You have to be in the network, which is a hassle but sometimes worth it.
The whole 'spicy' definition varies so much, you know? Some readers just want explicit smut, others want heavy BDSM dynamics or specific AUs. Tumblr's a mess for searching but great for curated blogs. I'd start with AO3, sort by kudos on the explicit-rated fics, and then see where those authors hang out. A surprising amount of the really passionate writers for Kiribaku also post shorter, racier snippets on Pixiv, but you need to navigate the Japanese tags which can be a barrier.

Look, I've gone down this rabbit hole a few times, and 'best' is tricky—it's so subjective depending on whether you want them as rivals, heroes, or something darker. The classic slow-burn that gets recced a lot is 'Between the Lines' by tessera. It starts post-graduation, with Kirishima and Bakugou on different hero agencies, and the burn is glacial. It's all about missed calls, shitty texts, and Kirishima overanalyzing every single interaction for three years. Some people find the pacing frustrating, but that's the point, right? The tension comes from their careers getting in the way, not miscommunication for its own sake.
I also keep going back to 'Red Riot, Dynamight' which is a weird one because it's an AU where they're both in a support gear engineering course. The romance is secondary to the plot about building a new type of armor, and the attraction simmers under the surface for like 40 chapters. The author really gets Bakugou's voice—grumpy, hyper-competent, but weirdly soft when Kirishima is struggling with a weld. The slow burn here feels earned because they're building literal and metaphorical foundations together.
Honestly, a lot of fics tagged slow-burn in this pairing aren't. They jump from snarking to kissing in five chapters. The real gems are ones where the 'burn' is in the character development, not just the pacing. Like that one where Bakugou has to learn to apologize, genuinely, for something he said years prior, and it takes him 80k words to even understand why it matters. I'm blanking on the title, but it's out there.

honestly, your main spicy havens are AO3 and some dedicated servers. Archive of Our Own is the undisputed king for a reason—their tagging system lets you filter for Explicit ratings and specific tropes like 'Established Relationship' or 'Pining' with 'Sexual Content'. You can really drill down. Wattpad can have some gems too, but it's a total mixed bag; you have to wade through a lot of poorly tagged, immature writing to find the good adult fics, and the search function is kinda garbage.
Don't sleep on Tumblr though. A lot of writers will post previews or links there, especially for more niche or kink-themed content. Following tags like #bkdk or #bkdk smut can lead you to writers' personal blogs where they host their racier works, sometimes linking out to Google Docs or smaller sites like SquidgeWorld. The vibe there is more conversational, and you can sometimes commission stuff if that's your jam.
A weirdly specific tip: check out any 'Bakugou Katsuki Week' or 'Kirishima Eijirou Week' events on Twitter. Writers often create explicit pieces for those prompts and post links. It's transient, but you can find some incredible, passionate one-shots that never make it to the bigger archives. My favorite BakuKiri fic of all time, this angsty road trip story with incredible tension, I found through a retweet.
