Looking for great Hinata/Kageyama fanfiction? I dive into this stuff all the time and my brain is a mess of rec lists, so here’s the short tour: start at Archive of Our Own — their tagging system is a dream for narrowing down exactly what you want. Search for ‘Hinata Shoyo/Kageyama Tobio’ or the ship tag 'Kagehina', then filter by rating, word count, and warnings. I personally sort by bookmarks and kudos to find long, well-loved works, and I often open the author's notes first to see their headcanons and warnings.
Aside from AO3, I poke around Tumblr (the tag search still turns up hidden gems), Wattpad for more casual reads, and FanFiction.net if you want classic fics. Reddit's communities have mega-recs and monthly recommendation threads. If you like curated recs, there are several blogs and Discord servers with reading lists (their spoilers are neat for fanfic arcs). For wildcards, Google site searches like site:archiveofourown.org "Hinata" "Kageyama" pull up fanfic gems that tags can miss. I always check the tags for tropes — slow burn, rivals-to-lovers, post-timeskip — and skim comments to avoid surprises. Happy reading; I hope you find that one fic that makes you cry and cheer at once.
