Finding the right niche crossover content can be tricky. Try filtering on Archive of Our Own by both characters and then adding the 'Crossover' tag. I've had luck pairing 'Blue Archive' with something like 'Persona 5' or even a classic sci-fi universe—the systems clash can be weirdly fun. Searching 'Blue Archive & (other fandom name)' often surfaces hidden threads on Tumblr or Twitter, where authors sometimes post links to their works on lesser-known forums or Google Docs.
Honestly, the tag system is your friend, but sometimes you have to dig. I found a surprisingly good 'Blue Archive'/'Cyberpunk 2077' fusion story just by scrolling through pages of the less popular crossover pairings. Sometimes authors don't tag as thoroughly as they should, so trying different search term combos or checking the bookmarks of people who write for one character can lead you down a rabbit hole of good stuff.

Len x Neiru? Honestly, I think the best stuff is hiding in the cracks of other fandoms. Since 'AI: The Somnium Files' is a murder mystery and not romance-focused, writers have to be creative. The peak of the tag is probably the detective-partner angle. I'm drawn to the fics that treat their bond like a slow-burn puzzle—Aiba coexisting with Date, Neiru learning to trust this oddball detective after the world he knows falls apart.
One story, 'Circuit and Synapse,' had them investigating a strange case where Aiba's data manipulation crossed into Neiru's psychic research. The dynamic wasn't fluffy; it was two professionals, wary but respectful, figuring out how their separate weirdnesses could complement each other. Those stories nail the bittersweet tension of two people whose normal lives are gone, building something new on the ruins. It feels authentic to the game's tone.
Wish there was more exploring Neiru's guilt and Len's amnesia though. Most writers just drop them into a generic crime plot.

Damn, that's a pairing I haven't heard discussed much lately. Takes me back. If you're hunting for specifically Len x Neru stuff, you'll have a bit of a niche treasure hunt on your hands. The most active pockets I've seen are actually on Pixiv, weirdly enough. The tagging system over there for VOCALOID stuff is pretty solid, and you can filter by character pairs. The downside is a lot of it's in Japanese, but browser translation gets you pretty far.
You can't really talk VOCALOID pairings without mentioning the old FFN and AO3 archives, though. AO3 has the better tagging for sure—searching 'Kagamine Len/Neru' will pull up the dedicated stuff. The collections aren't huge, but what's there tends to be more polished and narrative-driven. FFN feels like a ghost town for this ship now, but there are some classics buried if you don't mind digging through pages sorted by favorites from like 2012.
My personal dark horse recommendation is checking dedicated VOCALOID fansites or Tumblr blogs that are still kicking. Sometimes the best one-shots or drabbles never make it to the big archives, they just live on someone's side blog.

it really depends on where you hang out. The Japanese side of things is huge on Pixiv, obviously—that's where a lot of the original doujinshi and prose stories pop up first. You gotta filter by the レン×ネル tag, and some of the longer narratives there are surprisingly deep, exploring their dynamic as Vocaloids beyond just the fan service.
For English readers, Archive of Our Own has a dedicated tag, and the quality tends to be higher because writers put more effort into characterization. I've found some fantastic slow-burn AUs there that treat them like real people. DeviantArt is more of a mixed bag; you'll find a lot of drabbles and headcanon posts, but the tagging system is a mess. Honestly, unless you're fluent in Japanese, AO3 is your most consistent source for substantial reads. The community there just cares more about craft.
Tumblr still has a pulse for this ship, but it's mostly reblogs, moodboards, and micro-fics. You won't find many multi-chapter epics, but for quick hits of inspiration, it's not bad. I just wish more writers would cross-post from Pixiv to AO3 with translations; the language barrier is the real bottleneck for this fandom.

Hurt/comfort dynamics really define a lot of Len x Nero stuff for me. It's not just Nero nursing Len back from one of his magic-induced comas—though there's plenty of that—it's the quieter moments where Len's silence after a bad memory becomes something Nero feels compelled to fix with his usual stubborn, clumsy care. The trope flips sometimes too; Nero gets reckless, Len patches him up and then delivers a scolding that's all sharp words and gentle hands.
Another huge one is the 'found family versus actual duty' tension. They're often written as two people who shouldn't be close, one a church executor and the other... well, Len. The stories explore what happens when that professional line blurs into something like domesticity—Nero bringing groceries to Len's apartment, Len begrudgingly tolerating Nero's terrible taste in music. It's a slow erosion of boundaries that feels earned, not forced.
You also see a lot of 'mutual pining with a side of obliviousness,' which is perfect for their dynamic. Nero thinks his fascination is just part of the job, Len interprets every kind gesture as obligation. It makes the eventual confession, when it finally comes, hit so much harder because they've both been living in it for ages.

So, you're looking for the AUs where Eren and Jean aren't constantly at each other's throats in a post-apocalyptic hellscape? Makes sense. Their dynamic translates weirdly well to modern or historical settings, all that unresolved tension from canon gets fun new outlets. My reading habits skew toward Archive of Our Own, obviously—the tagging system is the only reason I can find anything anymore. You want to use the 'Alternate Universe' tag paired with 'Eren Jaeger/Jean Kirstein', then maybe narrow by specific AU types. I found a bunch of coffee shop AUs where Jean's the prickly barista and Eren's the overly intense regular, and some fantasy knight/squire ones that were surprisingly solid.
Tumblr still has a dedicated, if smaller, fandom pocket; searching the ship name plus 'au' or 'alternate universe' can dredge up links to fics hosted elsewhere, or those shorter snippet-style ones people post. I'd be a little wary of Wattpad for this specific pairing unless you're really digging; the quality can be a total crapshoot and the tagging is chaotic. A trick I use is to check the bookmarks of authors who write the ship well—they often bookmark similar vibes from others, leading you down the rabbit hole. Ended up reading a 1920s bootlegger AU that way, of all things.

Annie getting pulled into that mirror dimension thing in the Lost Girls OVA unlocked so many ideas. People run with that for AU setups where she's from some parallel reality and Eren finds her. Or my personal favorite lately is a prohibition-era bootlegger AU where she's the quiet rum runner and he's the idealistic new guy trying to take down the corrupt system from the inside. You get the tension of them being on opposite sides of the law but inevitably drawn together.
Honestly, the AU tag on AO3 is a lifesaver. Sort by kudos or bookmarks after 2020 if you want the more polished stuff. Tumblr's still got some moodboard-inspired mini-fics if you dig through the right tags, but the real meat is on Archive. Sometimes you gotta filter out the 'High School AU' or 'Coffee Shop AU' if that's not your vibe, but the 'Canon Divergence' and 'Alternate Universe - Modern' tags have some gems where the power dynamics of the original story get translated in really clever ways.

Archive of Our Own is the first place I'd check for that. The filtering system is the best out there—you can narrow by 'Alternate Universe', then by pairing, and even add tags like 'Canon Divergence' or 'Modern AU'. The sheer volume of 'Sailor Moon' content on there means there's a lot of 'UsaMamo' in creative settings. I found this one sprawling, corporate rivalry AU last year that was shockingly good, which I never would have stumbled across on a smaller site.
I'd also poke around Fanfiction.net, though the tagging is less precise. You have to manually search phrases like 'AU' or 'Alternate Universe' in summaries. It's a bit of a slog, but some authors who've been writing for decades have their classic longfics only posted there. Some of those older, epic-length stories have a different flavor than the newer, trope-driven stuff on AO3.
