Emperor au headcannons for Ushijima Oikawa and Kageyama with empress s/o
I can see him seeming super serious about his Emperor work, but he’d let you sit in on meetings with him if you want (and as long as you “behave”).
If you have suggestions at meetings, no matter how “absurd” his advisors or others may think, he always makes sure they give you the respect and attention he absolutely believes you, as his Empress, deserve.
Not one for PDA, but he won’t tell you off if you grab for his hand or have him come down to your height to pepper his face with kisses and the like. He actually very much enjoys your attention.
BUT if you do get a little handsy, that’s when he really shows his assertive/aggressive side. With the same heat and passion as he has on the battle field, he’ll grab your wrist and take you down a dark corridor and have his way with you.
Considers it treason if someone walks in on you guys doing the do lmao. It takes your convincing to have him lessen the death sentence to something like. Cleaning out the stables or something lmao.
He was the lonely and cold beautiful type of prince….that is, before you. He’s always had legions of devotees that have loved him long before you came into his life. So when their object of affection, their idol, changes to a more shining, happy, kind prince, they kind of resent you for turning him into something they aren’t used to.
He’d be fiercely protective of you because he’s especially aware of some of his subjects’ resentment. If he’s busy and can’t be there himself, he never lets you go without his most trusted guards and knights - Iwaizumi, Hanamaki, and Matsukawa.
Unlike Ushijima, he doesn’t really let you sit in on meetings with him. He knows what the business side of being an Emperor turned him into; he doesn’t want to risk “tainting” your brilliance and beauty with the drab side of things.
BUT he is definitely grateful for you wanting to share his worries and stresses. He finds so much comfort. The time you share with him is the happiest not only for you two but for the rest of the Empire as well.
If something ever happened to you, though, I could definitely see him pulling a Song of Achilles on everyone’s ass.
A young and inexperienced Emperor who was probably put on the throne much too soon. Since he is a young ruler, you become Empress through an arranged marriage. You have a little more experience in the politics of ruling an empire because maybe more exposure to all of it? The only reason Kageyama doesn’t know as much is because I think he just wasn’t able to learn it all in the time before he was thrust into his position.
He’s a fierce and aggressive emperor, so it definitely takes your wisdom to talk him down and get him to think things through before acting.
His army and close confidants (which don’t become that close till you showed up, kind of the same way Karasuno and Hinata get him to open up from the “Ou-sama” persona in canon) are really grateful for your presence because they can see how he’s changed as well.
He’s inexperienced as a ruler AND a lover, so if you grab his hand while walking down the corridors or in the garden, he’ll get really flustered it’s really cute and unheard of. Don’t think lessening the surprise will help either; if you ask if it’s alright to hold his hand or give him a kiss or anything, he gets just as flustered if not more.
