There are a bajillion Marriage Hunt AUs and not a single one for HashiMito. I don’t even like the trope because bride kidnapping was a real thing where men captured the women they wanted to marry and then raped them - and to me, personally, that’s reason enough not to enjoy a romanticized version of it. But see, I’m a spiteful bitch and the fact that there are so many MadaTobi and TobiIzu Marriage AU fics but not a single HashiMito one makes me want to have one now.
So…
This is Hashirama’s fourth time participating as a hunter in a marriage hunt. The last three times, he claimed he hadn’t been able to capture anyone, which is a bald-faced lie considering he’s one of the strongest shinobi in all of Hi no Kuni if not even all elemental nations, and the elders know it. But it’s not like they can do anything about it except force him strongly suggest to participate in another one.
This time, however, he is considering taking the hunt seriously for once. One of the possible brides is a Nara - the second child of the current clan head. Albeit unfortunately a man, thus not possible to grant Hashirama heirs, which the elders will have objections about (even though they only care about the Mokuton, which they know only appears in every few generations, so the chances that a child of his would inherit the Mokuton are practically zero), he has heard of the intellect that runs through Nara clan head’s family.
The first child would’ve been more fitting, for one she’s a woman, and for another she’s rumored to be the smartest Nara as of yet, but as the direct heir, she naturally can’t marry out. So Hashirama will have to do with the younger brother instead. He isn’t sure if he wants to have sex with a man, but Hashirama has never been fond of tradition anyway so he may as well just ignore this one, too. What he needs, is someone strategic to help him make peace with the Uchiha, and since Tobirama is unwilling to hear him out, he may as well capture himself a personal strategist via a marriage contract.
(And here Tobirama always claimed Hashirama can’t think ahead. Ha, take this!)
Sure, if it was up to Hashirama, he’d prefer his future wife someone to be he has already gotten to know and has had time to court and develop feelings for but since he’s clan head, he can’t have everything he wants, so this is his next best option.
When the hunt starts, however, Hashirama doesn’t immediately chase after the Nara whose name he unfortunately already forgot. He keeps an eye on him, to see what kind of traps he comes up with against his pursuers, and if Hashirama is impressed enough, he will try to strike a conversation with him and see, how he feels about the notion of peace. And only then will he decide if he will capture the man into marriage or not.
For now, he just runs nonsensically into the forest, which is all the more surprising when golden chains wind around him and capture him in a hard grip that makes him stumble and almost fall to the ground.
“Wha-?”
“Senju Hashirama,” he hears Uzumaki Mito’s voice at the other side of the chains, standing proudly a few branches behind him, her chin held high and her expression smug, “I, Uzumaki Mito, declare my intention to hunt you for marriage. Do you accept?”
Her tone is steady and imperious but not unkind. Hashirama blinks in confusion.
“But I am registered as a hunter and not bride-to-be?” he helpfully points out.
“Not anymore,” Mito says and gestures to his wrist, retracting her chains from his person, now that she has his full attention. Where a blue bracelet should be that identifies him as a hunter is now a red one instead. A bride’s bracelet.
Hashirama gapes. “How–?”
He had noticed Mito’s hard stare before the hunt had begun. And when he had looked over to see who kept staring holes into him, Mito hadn’t even had the decency to look away, had just looked at him with an intense gaze, not paying attention to the rules of the hunt that were being read aloud. Hashirama had wondered if there had been something on his face and prayed it wasn’t leftover from his breakfast.
Now he wonders how she managed to exchange his bracelet without anyone noticing, including him, all the while she had been lined up quite a few paces away from him with two other hunters between them.
“I can’t marry out, I am clan head,” he then mentions carefully, although Mito knows already as much. They have, after all, met a handful of times already. But it bears mentioning, since Mito seems to have forgotten how a marriage hunt works.
“I am aware. And I am, of course, willing to marry into my wife’s clan instead. My wife’s duty takes precedence over the nature of our marriage.”
Huh. Hashirama has met Mito before, so he knows she’s a smart woman - Ashina’s head strategist even. She’s witty and incredibly skilled at the arts of sealing. She’s also an exceptionally beautiful woman, which is not important in this context, but Hashirama can’t help but notice anyway. And right now, something akin to fear and hope shimmers in those coal-dark eyes, in contrast to the confident pose she’s holding.
So, stupidly, Hashirama doesn’t think twice when he answers, “I accept.”
The brilliant smile Mito gifts him then is all the confirmation he needs that this was the right decision. He may not have had the time to properly court Mito and get to know her better, but he can tell without a doubt, this will be more than worth it.
Without further ado, Hashirama runs.
