Alright now starts my bout of kageyama family headcanons.
The Kageyama Family is one overarching headcanon that Kageyama Tobio has 16+ siblings, and there are many sub headcanons, including Daichi being Kageyama’s 4th Uncle, Kiyoko being his cousin, Oikawa’s nephew being his nephew, and various other ideas.
I was kind of reluctant to post them since the idea came from a big haikyuu headcanon blog, imaginethehaikyuukids, but I think as long as I give everyone credit I should be fine. This post will have all the links and such, but all posts will be tagged with the creator of the character, kageyama family, and imaginethehaikyuukids
So there are some main contributors to the kageyama family, other than the original blog.
First up is anywayimnikki who runs the askkageyamafamily blog where she answers any and all questions about the family to the best of her ability. Before she ran askkageyamafamily, she ran an ask blog for Keiko, the younger sister who is closest in age to Tobio. When it was accidentally deleted, she created the family version.
Second up is my best friend ZodiacLeopard, who actually helped me come up with half the headcanons here, or at least has heard them before all of you. They run the askthekageyamatwins blog, which features Tobio and his identical twin, Akio.
And thirdly there is Xankyou, who created Hiroto and his band mates. They don’t have a specific ask blog, but there is art they made.
Ok and I’ll mention myself since I’m running kageyama family week (with help from anywayimnikki and zodiacleopard) and have written two fics featuring them, so if you want to check out my main blog, it’s actualscienceside
Of course, you can find most of the headcanons on the imaginethehaikyuukids blog, and pretty much everything else on one of the other four blogs I mentioned. Also the whole concept is fantastic.
