Does the added relationship have to be in a fandom that's already on the list? If not, I'd like to request this one:

Fandom: ノブナガン | Nobunagun
Ship: Sio Ogura/Adam Muirhead

(It's a pretty obscure fandom. As you can see here, only one person besides myself has put a pairing fic for these characters on AO3, and they didn't even format the tag right.)
