Which Platforms Host Unique Tanjiro X Zenitsu X Inosuke Stories?

Archive of Our Own is basically the hub for quality fics like that. The tag filtering is so precise; you can search for 'Kamado Tanjirou/Kamado Nezuko Kamado Tanjirou/Kamado Tanjirou's Family' and then add 'Agatsuma Zenitsu' and 'Hashibira Inosuke' as additional characters, or use the ot3:Kamado Tanjirou/Agatsuma Zenitsu/Hashibira Inosuke tag if it exists. Sorting by kudos or bookmarks will surface the popular ones. I found a really long, atmospheric fic there that nailed the dynamic of them recovering together post-Mugen Train, focusing on quiet moments and shared grief. The writing felt very true to the characters. Wattpad's algorithm is less reliable for quality, but I've stumbled upon some surprisingly heartfelt shorter pieces by searching the ship name 'TanZenIno' and filtering by 'Featured'. Sometimes the gems are buried under less polished works, though. Another spot is Tumblr. A lot of writers cross-post snippets or link to their AO3 from there. Following tags like #tanzenino or #kimetsu no yaiba fanfiction can lead you to curated rec lists from other fans. That's how I discovered a fantastic modern AU where they run a bakery together—silly premise, but the author captured their bickering and loyalty perfectly. For a more focused hunt, I'd check if there are any dedicated Discord servers for Demon Slayer fanfiction. Those often have channels for fic recommendations where members vote on their favorites. The signal-to-noise ratio tends to be higher because the community self-moderates.
