Arranged marriage / omega verse AU
Butsuma is dead, leaving Hashirama as the clan head and Tajima has stepped down after a serious injury he sustained the that last battle with Butsuma.
Now that Hashirama and Madara are clan heads they decide to pursue peace.
When peace is agreed upon the Uchiha demand a marriage to prove the Senju 's commitment.
As an omega of the main line Tobirama is the obvious candidate.
The Uchiha decide that is acceptable and a marriage happens between Tobirama and Madara (an alpha).
Things are going well they have been married for 6 months and Tobirama is already expecting.
It's Izuna's 19th birthday and there is a big party to celebrate with extended family, friends, and the elders.
Tobirama ends up admits his is only 9 days later.
Madara asks him if he is turning 19 or 20? He wasn't sure how old Tobirama actually was.
Tobirama gives him a weird look and says no, I'm turning 17.
Absolute silence descends. No one is speaking and everyone is staring at Tobirama in horror.
But none more so than Madara who looks like he might throw up.
Izuna says he must surely be joking. They joined the battlefield at the same time! They have to be closer in age.
Tobirama's just tilts his head and says his father had him joining the battlefield when he was 7. He was actually more surprised to hear Izuna was that much older than him. He too assumed they were the same ago.
Tajima, his face red with rage, asks how could his brother sell him off in a marriage when he is still a minor. That's beyond fucked up.
Tobirama defends his brother saying that Hashirama was the only thing that had stopped him from being married off when he was 15, he was grateful for the extra year of being a shinobi.
Everyone looks even more shocked and outraged. 15?!? That's beyond messed up.
Tobirama says it's a common practice. His mother had been married to his father on her 15th birthday.
Tajima swears and asks how old his father was, to which Tobirama responds with he was 21. He, like all the clan alphas had to prove they could survive long enough to be gifted an omega wife.
Tajima swears and says if he had known he would have tried harder to kill his father.
Tobirama is completely confused as to why everyone is looking so shocked and angry. How old are the Uchiha when they marry?
One of the elders inform him that they do not let anyone, alpha, beta or omega Mary before they are 18.
Tobirama is confused. How do they keep their numbers up waiting so long for children?
Then he is even more shocked to hear some couples even wait a couple of years before having children. Tobirama tells them that in his clan omegas are expected to have a minimum of 3 children in the first 5 years.
Izuna chokes and asks what if one of the omegas doesn't want to have 3 kids or doesn't feel ready for them when they marry.
Tobirama simply says it's not for them to decide. That decision rests with their alpha.
He hears someone in the back actually puke.
Madara, pale as a ghost, asks him if he had actually wanted to have a baby right away or if he would have wanted to wait?
And his response breaks the Uchiha's hearts.
Did I have a choice? Tobirama asks.
Making it clear to all of them that no, he hadn't wanted a baby. Or at least not yet
Madara looks close to tears.
Tajima is livid.
Izuna looks horrified.
Tajima declares that they will never have a joint village. He will not risk his clan being subjected to such barbaric practices.
Tobirama is now horrified. He never should have mentioned his birthday. He was shocked the Uchiha clan was so different. Both he and Hashirama had assumed they were the same.
Tobirama asks why? He tells Tajima that if it's such a big deal his brother will change tradition in the interest of peace and a joint village. The safety of children in all the clans of fire was his priority.
Tajima, the elders and Madara agree they will discuss it at another time and that they will request more information from Hashirama as well.
The party is pretty much ruined at this point, thankfully Tobirama's comment came towards the end of it.
The head family all leave for their joint home silently. Madara is having trouble even looking at Tobirama.
He asks Madara if he is angry with him.
Madara explains that no, he is angry on his behalf. And that from now on he will do the right thing and remain away until Tobirama is 18 and has had time to decide what he wants.
Tobirama is horrified, he has come to really like his husband, and he doesn't want to go to an empty nest alone. Why was Madara abandoning him? He was sorry he said anything.
Madara tries to explain it's not right, but all Tobirama is hearing is rejection.
Tajima intervenes and tells Madara they are already mates. He needs to continue to be a good and attentive mate. Just because they had different cultural beliefs and that it felt wrong didn't mean he could pick his beliefs over Tobirama and their baby's health and happiness.
Madara is conflicted, but he sees the hurt written across his mate's face and apologizes for saying he would leave.
Madara spends the next months conflicted by what he knows is wrong and his mates health and mental well-being. In the end he decides he was being selfish and his mate and their baby have to be his priority.
They have a happy healthy baby, but Madara puts his foot down on having more. They will not until Tobirama is a minimum of 18 and actually wants to. If he wants to. Madara is perfectly content to only have their little girl. She will grow into a wonderful clan head.
Hashirama doesn't fight Tajima on his demands. After his engagement with Mito, who was 20 and allowed to choose when she married and have children, he started to think that it was a much better practice. And less risky for the mothers health.
Tobirama ends up being the last omega ever used as an exchange in a marriage and the last one under 18.
Despite what Madara worried about, Tobirama actually did want a big family. He wanted at least 4 children, but if Madara allows it, he would like to still be a shinobi. Madara has no issues with that. He won't go on many missions as the clan head and he can absolutely be a stay at home dad.
