Yearly guess the Yuletide fics thing

So, this year I wrote 5 fics in 5 fandoms for 5 people.
Of these, I’d written in 4 of the fandoms before.
3 were for video games, 1 was for a webcomic, and one was for a music video.
4 were for western-based fandoms and 1 was for an eastern-based fandom.
4 are in main, 1 is in madness.

Can you guess what I wrote? Comments are screened.
