A/N: Everyone is 18 or older. Unfortunately, this is a men-only chapter. I'll be posting something else (especially for Nezuko and Shinobu, but everyone will be in it) tomorrow!

CONTENT WARNING: Chapter contains references to abortion. If you're uncomfortable and/or will be triggered by that, then feel free to skip the Kizuki/Muzan section. (Muzan's section will be a bit coercive, and I apologize in advance for any discomfort.)

Tanjiro:

Tanjiro is more shocked than you've ever remembered him to be. It takes a few minutes and some stuttering questions ("Is-- is it true? Are you serious?") before he finally rushes to you and takes you into a tight hug, tears wetting your shirt. He's so happy he can't stand it; for so long he's dreamed of having a family again, and even though he got some of that with Zenitsu and the others, having someone so dear to him, his own child, feels like a dream. He immediately goes to tell Nezuko and it ends with the three of you crying, overjoyed, on the floor.

Zenitsu:

Zenitsu immediately faints.

When you finally manage to wake him up, he lunges at you and glomps you, crying happily and repeating "Thank you thank you thank you thank you thank you" over and over again. Zenitsu has always dreamed of marrying a girl and settling down, and the second step of one of his greatest dreams is finally coming true. He gets so excited and wants to start planning immediately. He pens a letter to Jigoro, asking if he and Kaigaku would like to meet for dinner for special news.

Inosuke:

At first, Inosuke doesn't seem to give it much thought. He just raises an eyebrow and asks you about it. The first thing that comes to mind: "You're pregnant? ... so that means you're going to have a piglet?"

Once you stop laughing, you explain it further to him. He seems a little uncomfortable with the thought of a baby, but he's proud enough of the news that, when it finally sinks in, the next time you both meet with the others, he announces to them that he's more virile than all of them. (You promptly smack your head into a tree in embarrassment.)

Giyuu:

Giyuu doesn't know how to properly react at first. He's stunned in his spot for a while before he looks up at you and in the tiniest voice, "R-- really?"

When you confirm, he seems to hesitate before gently touching your stomach. He admits that he never thought he would live to see himself become a dad and bursts into tears. He hugs you tight and lets it all out while you soothe him.

Kyojuro:

Kyojuro is frozen for a moment, but then the biggest grin you've ever seen spreads across his face and he picks you up, spinning you around in joy. He's so excited he's like a puppy, asking you questions and touching your stomach and holding you tenderly. He hasn't been around a baby since Senjuro, and he remembers his brother fondly. He remembers the long nights his mother had, but he's convinced that you both can do it. The two of you immediately make plans to tell his father and brother the good news (as well as make the grumpy grandpa-to-be smile, dammit!)

Muichiro:

Muichiro doesn't seem to hear you at first. But then your words hit him and he freezes in his spot, turning to stare at you with an unreadable face. Then his eyes soften and he reaches for you, pulling you in for a tight hug. He's nervous, but excited -- he's wanted something to fill the hole his family left, and while his friends have filled most of the hole, the prospect of being married to you, and now having a baby -- this is easily some of the best news he's ever heard in his life.

Gyomei:

Gyomei's eyes immediately fill with tears, and he presses his hands together and starts to pray. He's overwhelmed with the news -- nervous, surprised, excited -- it's been so long since he's taken care of children that he doesn't know if he can do it for a moment. Part of him feels horrible guilt for it; while his orphans were long dead, here he was, sharing a happy moment with his wife, about to have a child of his own. But then you gently place your hand on his wrist and smile up at him, and he remembers how blessed you both are to be alive. You reassure him and the two of you share a kiss. It's enough to make a grown man cry... and that's okay.

Sanemi:

Sanemi is shocked beyond belief for a moment. Then he's so careful, so gentle when he asks, "Are you really--?"

When you say yes, his eyes fill with tears for a moment before he tries to discretely wipe them away. He pulls you in for a hug, hiding his face in your neck. He's so nervous about it he can't stop shaking. After what happened to all of his siblings in his childhood, he never wanted to even think about caring for a child again -- but now here he was, on okay terms with Genya, with a wife, and now, a child on the way. He loves you, all three of you, with all his heart, even if he doesn't always show it.

Akaza:

Are you a demon?

If not: Although his first reaction is to be overjoyed, Akaza feels horrible.

Demons and humans can't have children together. With a demon mother, their body will absorb the embryo immediately. With a human mother, the embryo/fetus will begin to kill the mother from within. In 99% of cases, neither survive. In the other 1%, only the baby will be born, but the baby will be significantly weaker and will likely not survive infancy. The entire pregnancy and birth is horrendously painful and the mother gets sicker and sicker until she's bedridden and almost comatose, unable to move until she dies.

While Akaza has dreamed of having a family of you, he doesn't want to lose a loved one so soon again. He'll beg you to abort the baby. If you refuse, he'll instead beg you to let him turn you. He knows you don't want to discard your humanity, but if you can't and/or won't abort the baby, then it's your only option of survival.

If so: Akaza is ecstatic.

All he ever wanted was to have a family of his own and get away from his ugly past. When you come to him, telling him that you're pregnant, his first reaction would be to question it, but when you confirm that yes, you want this, and yes, he's going to be a father, he starts to cry. He picks you up and spins you around, telling you how excited he is and how much he loves you.

Douma:

Are you a demon?

If not: Douma is incredibly disappointed.

He'll ask if you want to keep the baby. He'll be incredibly serious when he tells you the odds of survival and then ask you again. If you don't want to abort, then he'll ask if you want to be turned. He wants you to be safe no matter what.

If so: He's a little nervous.

Douma has some experience in taking care of infants (thanks to Kotoha), but he's never had to think about his own children. Still, he's interested in seeing where this goes.

Kokushibo:

Are you a demon?

If not: Kokushibo is apprehensive.

You're the first human in four whole centuries that he feels a legit connection with (and it's not just about your abilities anymore). The last thing he wants of you is to have to watch you struggle through a doomed pregnancy and ultimately die, whether or not you take the baby with you at birth. Kokushibo does not beg, but eventually you'd find him trying almost desperately to persuade you to abort the baby to save your life if you decide not to turn.

If so: Kokushibo doesn't know how to react at first.

He faintly remembers his own human wife and children, so he has a feeling he knows what to do, but he doesn't know if he could do it again, especially in this state. It'll take a lot of reassurance and space between you two for him to eventually come to terms with it and accept it. He's proud deep down that you're having a child, and with his meager memories (which, really, aren't much, considering how busy he was at the time), he can and will be a father.

Muzan:

Are you a demon?

If not: Muzan is upset.

He had actually caught feelings for someone for the first time in, well, his entire life. And to hear that you, his human wife (his actual human wife, mind you), is pregnant, it turns his entire plan up on its head. He is not going to lose you, daylight be damned. He'll explain everything that he knows about demon-human pregnancies, and he'll ask if you want to turn for your own safety. It's either that or abortion. This is one of the few areas where he will not accept no for an answer, and it will lead to a few fights between you. Once you do make a choice, however, he arranges for the least amount of pain possible for you. He cares a lot about you and will not let you die. He understands that turning you will deprive you of your freedom (and he hates to think of it), but you're his family now, and he doesn't want to lose you like he has others, like Rui.

If so: Muzan is pleased.

There aren't very many cases of demons procreating with one another, given that they tend to be pretty hostile to one another unless under an alliance. And now the most powerful of them all is going to have a child with another powerful demon (because come on, you don't believe that your spouse would let you be a weak starter, did you?), and what if this is his chance to finally unlock the secret to walking in the sun? Until now, no pureblood (AKA, him) had ever conceived with a changeling (AKA, everyone else). What if the child had new abilities that he could not? Old habits admittedly die hard, and for a while he'd genuinely wonder about devouring the child at a certain age if they showed promise. But then he'd think of you and hesitate for once, ultimately deciding that there must be another way to conquer daylight.

Yoriichi:

Yoriichi is. just. so shocked.

He honestly never thought that he would be able to have a family like this again. When Uta and the baby died, they took a piece of his heart with them. But now here you are, happily pregnant, and he's on top of the world. He sweeps you in for a tight hug, tears burning in his eyes as he thanks you.
