Aaron X Ein Romane & Geschichten

Man, crossing over 'The Iron Druid Chronicles' with 'The Einstürzende Neubauten musical project'? Now that's a specific and wonderfully niche pairing itch to scratch. It's the kind of deep-cut crossover that thrives almost exclusively on fan-created hubs, as you're unlikely to see it on big commercial platforms. Your most likely hunting ground is Archive of Our Own, known universally as AO3. The tagging system there is your best friend. You'd want to search for the fandom tags for both 'The Iron Druid Chronicles' and 'Einstürzende Neubauten', and then use the 'Crossover' filter or look for works tagged with both fandoms. The beauty of AO3 is that if even a handful of people have written for this pairing, they'll have used those specific tags, making the stories findable despite the obscurity.

If you strike out on AO3, your next stop should be more generalized fanfiction archives like FanFiction.net. While its search and tagging is less granular, you can still try searching for 'Atticus O'Sullivan' or 'Aaron' paired with 'Neubauten' or 'Blixa' in the summary or title. Sometimes, these ultra-rare crossovers pop up in author-curated collections or communities dedicated to one of the source materials, where a creative writer might have decided to blend their interests. I'd also recommend checking if there are any active forums or Discords for either fandom; a passionate fan might have written a one-shot or snippet and shared it directly in a discussion thread, which wouldn't necessarily get indexed on the big archives.

The key is embracing the treasure hunt aspect. For a crossover this unique, finding even one well-written story feels like a major victory. I'd sort any results you do find by kudos or favorites to immediately surface the pieces the community has resonated with most. Sometimes, the most rewarding finds come from clicking on an author's profile after reading a good story—they might have other experimental crossovers or similar vibe pieces that aren't as prominently tagged. It's a process of following creative breadcrumbs through a very specialized corner of the internet.

Ever since I finished 'Inazuma Eleven', I've had this urge to see Aaron and Ein interact more, but the official material is so sparse. So, I went down a rabbit hole and found a few fics that really capture their potential.

One that stuck with me is 'Unspoken Resonance' over on AO3. It’s a post-canon exploration where they’re both trying to adjust to a more normal life, and the author nails Ein's quiet intensity and Aaron's more grounded leadership. The build-up is incredibly slow, almost painful, but in a good way. It’s less about grand soccer battles and more about shared cups of tea and hesitant conversations, which felt surprisingly authentic for them.

For something with a different flavor, 'Gravity’s Pull' takes a sci-fi AU approach, casting them as rival pilots. The dynamic shifts completely, but the core of mutual respect and friction remains. It’s a fun read if you want to see their personalities transplanted into a new world.

Honestly, starting with the more character-centric, canon-divergent stuff gives you a better feel for why this pairing works before jumping into the wilder AUs.

the crossover scene for Aaron and Ein is a weird little niche. Ao3 is the undisputed king for sheer volume and tagging sophistication, but the quality is... uneven. You get these sprawling 80k word epics right next to barely coherent drabbles. Wattpad has a younger crowd, so the stories there tend to be more trope-heavy—lots of high school AUs or soulmate marks.

If you're after something specific, like a fusion with 'Fullmetal Alchemist' or a darker cyberpunk twist, your best bet is actually smaller, dedicated forums. I found this incredible noir-style fic on a now-defunct Proboards site that blended the characters into a 'Blade Runner' setting. It's gone now, which kills me. These days, I mostly stick to Ao3 and use the exclude filters aggressively to avoid the meme fics that have been popping up lately.
