Kingdom Hearts Fanfiction
Square Enix's Disney-Final Fantasy crossover saga about Sora, his keyblade, and a mythology of hearts, Nobodies and time travel that grows more baroque with every entry. The fanfic community has spent twenty years writing Sora/Riku's light-and-darkness devotion, Axel and Roxas's ice cream sunsets, and the Wayfinder trio's broken decade, often fixing what the convoluted canon breaks. Organization XIII slice-of-life, Days-era grief fic, and AUs that untangle the Xehanort knot keep the archive perpetually busy.
