in each clones headcannons, i will say who got you pregnant! in sekidos you are a demon, in karakus you are a human, in aizetsu's you are half human half demon, and in urogi's you are also a harpy!

Warnings:Nesting on urogis part, demon x human pregnancy,pregnancy risk,pregnancy,labor, possesive sekido,slight cussing,demon x halfling pregnancy, demon x demon pregnancy. 

Sekido- Urogi got you pregnant. Sekido wasn't happy that urogi got you pregnant first. He was happy for the four of them to have a kid with you though! It's very rare for Sekido to feel ANY joy at all, however when you broke the news to him he couldn't help but smile just a wee bit, Now throughout your pregnancy he was ontop of giving you your cravings,bringing special gifts for you and the baby. He insisted you stay resting,and only eat,get dressed,bathe or use the bathroom. Even though you voiced to him you could still do certain things he refused to hear you out. He was a little bit paranoid and more protective during the pregnancy, Muzan even vowed to kill any demons who tried to kill you for the child, not because he liked you or anything, but because for the first time in CENTURIES two demons managed to procreate. 

When it came time for birth, the last two weeks of your pregnancy were spent resting in Sekido's arms, he refused to let the others touch you at all despite the baby being Urogi's. The only time the other got to even come near you was to bring you food,offerings,rub your sore feet,massage your back and or to join the cuddles with sekido's permission. Urogi even built you a nest in which he demanded that you give birth in (typical harpy behavior), Sekido agreed to only that single request. 

Unfortunatley the clones were out on a mission when you went into labor.  Luckily they had trusted kokushibo to watch over you, so when you went into labor muzan was summoned upon kokushibos request. You refused to leave urogi's nest despite muzan saying it was safer to give birth at the infinity castle. The clones arrived 6 hours later, You were still waiting to push but were super close, Sekido sat behind you to help with you bracing yourself, Aizetsu held your left hand, Karaku and Urogi got towels,blankets,water and such. 

After 10 hours of labor your first daughter was born, notice how i said FIRST? yeah, because as soon as you had your daughter with her little golden brown eyes and her lil horn on the right side of her head, muzan then said. "There is one more." And thats when you absolutely PANICKED, Already bawling hard enough from the sheer pain you were in, it took 4 more hours till you were ready to push.

So after 14 hours of labor you had two beautiful baby girls, sekido kissed the side of your head as you finally relaxed, sniffling. Thankfully one girl had golden brown eyes like Urogi, and the other had Hazel eyes, so it was easy to tell them apart. You decided since sekido took care of you the majority of the pregnancy (mans literally did that shii possesively) that he could name the first girl, urogi could name the second. Sekido decided her name would be Kozuki (pronounced co-zoo-key), Urogi named the other Aria.

Karaku-They don't know, because the last time ya fucked was when ya'll did it, all four of them and you. When you came to them, pregnancy test in hand. The most concerned was Karaku, he may not have the biggest brain, but he is smart enough to know that demon x human pregnancy can be life threatening. He voiced to you that you could very well die if you kept the baby. After all, in most cases the baby absorbs the mother throughout pregnancy, and in other cases the baby never develops and kills the mother. So he gave you an option, Either you take the risk of having the baby human, or he takes you to muzan for you to be turned into a demon.But stubborn as always you chose option A, determined to prove to him you can do this. So began your pregnancy, Karaku tried to have you rest as much as possible, he was paranoid and scared you wouldn't survive the pregnancy, muzan was amused you'd made it to month 4 no effects but he had little to no faith you'd actually survive. 

it was until month 6 did you feel increasingly ill and lightheaded so immediately you went to shinobu your bestest friend, where she informed you your symptoms were because, you were pregnant with triplets! So when you came home that night pale in the face like you'd witnessed a murder, All four clones were concerned, sekido was more angry that you were acting so annoyingly strange but he felt a small bit of concern. "i...i-i-...uhm.." Stumbling over your words unsure how to break the news to them, "Well!? cmon we haven't got all fucking day!" Sekido snarled, "my dear..please don't cry"Aizetsu whimpered, "heyheyhey cmon cmon!!" Urogi over joy for news as always and then there was karaku, who stared at you with pure concern, nothing else but concern. "IM PREGNANT WITH TRIPPLETS!!" you wailed, you weren't upset in the slightest, just shaken up so you were panicked, "WHAT?!" sekido shrieked, "T-THREE?" Aizetsu for once was actually showing his surprise, Urogi had his jaw hanging open, And karaku? yeah Karaku fucking FAINTED. Which only worsened your panic and made you cry even harder, the pregnancy hormones taking over. 

Fast forward, the last three weeks of your pregnancy you became ill, it wasn't because of the baby, it was because you had come down with a cold, of course it was winter so it wasn't surprising. Which made things worse, the clones had to take care of everything, you tried to help them learn to cook and sekido actually understood so her took the liberty of that. Karaku took the liberty of cleaning,Urogi doing laundry and Aizetsu keeping the fireplace stocked with wood and keep the fire going.  

You went into labor a week early, nobody was home. they were at an upper moon meeting. SO for 20 hours, you were having a home birth, muzan had given them a mission despite karaku and aizetsu being worried you'd go into labor, TOO LATE. Your first son was born on the 21st hour,the 2nd son on the 24th hour and right as the clones arrived back home you were pushing the last baby on hour 25. Intermediately They we by your side, Aizetsu and Sekido cleaning the first two boys up while Karaku and Urogi helped you push the last out, on the 26th hour you had your daughter. 

Surprisingly ALL of them had karakus eyes. The first son had jade green eyes, the second son had dark green eyes, but your daughter had the most beautiful turquoise eyes you'd ever seen. 

You named your first son Kai, your second son Ojiro and karaku named your daughter Tara. Guess we know who got you pregnant now.

~end~

Aizetsu-Aizetsu got you pregnant. He was very happy to say at the least when you broke the news to him. He knew he was the father because literally he's been the only one fucking you for the past month (the other clones were booked on missions) so he's the only one who's been cumming inside you and made said baby. Now, at first aizetsu was a bit worried given you are half human and half demon but you assured him that your other (who was in fact,a human) gave birth to you, so you could give birth as well but with less risk since your father was a demon and you are a halfling. After you re-assured him, the other clones arrived. 

When you broke the news to them, Sekido immediately busted into laughter,  "you two?! a baby? this has to be a fucking joke!", mean while karaku and urogi were standing there dumbfounded, karaku was jealous that it wasn't him and urogi was just shocked. "N-No sekido, Y/N is pregnant..with my baby" aizetsu managed to stutter out. You wacked sekido upside the head for his smart-ass comment he would respond to aizetsu with. "great now we're gonna have a crybaby mixed with a angry sweetheart for a baby,hell has fucking frozen over. - HEY OW! YOU LITTLE-!", but before sekido could even react you said "Hit me i dare you." , grumbling he sat back down. sekido wasn't scared of you by any means but the last fight you two had you had, you took sekidos head off (resulting in muzan scolding and threatening you after he had found out.).

Fast forward, you weren't due for a whole nother month but your baby decided they wanted out NOW. So you went into labor a month early, You went through a painful 23 hours of labor, your baby girl entered the world at Midnight on October 31st. She looked just like aizetsu, You and aizetsu had agreed that if it was a boy you'd name the baby and if the baby was a girl Aizetsu would name her. 

Aizetsu chose your late mothers name, June. 

~end~

Urogi-urogi got you pregnant, it was mating season. yeah so being a harpy just like urogi mating season was HORRID. The nesting,the non-stop sex, the gifts,and the hormones. Now here's where everything is weird because you see as a harpy you'd think you would lay eggs right? WRONG!!. Somehow you ended up with an entire fetus in the womb and you nor urogi never noticed till you were about 6 months along and had gotten aggravated about trying to lose this supposed "weight" you had gained. that's when muzan gave you both the news, you were six months pregnant, the amount of children was unknown. the other clones didn't really care, urogi did though. You fell in love with urogi, so you weren't dating the other clones as you considered them siblings. 

Now since you just found out you were six months along, you only had 3 months to prepare for what's to come.  Urogi helped you build your nest, he kept you fed and warm, he basically did all the work for you while you relaxed. come month 8 you barely even WANTED to eat because you were so tired and just wanted to sleep. you weren't due until december 20th, and you were determined to have that baby december 20th.

Baby did not agree, on Christmas morning your water broke. You groaned in annoyance at first thinking you peed yourself again on accident, then the realization set in and you SHRIEKED.  Urogi came RUNNING into the room thinking something hurt you, When you explained in tears and in pain he was quick to act, grabbing the towels,water,and blanket for the baby.Now you hadn't started contractions so you had to stay on high alert which meant missing the christmas demon party. So urogi had told Sekido,who groaned in annoyance,to let muzan know. 

It wasn't until about hour 10 did your contractions become more frequent and worse, you had ZERO pain tolerance whatsoever so you had to bear with the pain, on hour 13 your sweet baby boy was born, wailing and crying while being cleaned up. You wee in immense pain and extremely worn down, so you left the naming and everything to urogi. 

he named your son Kodora.
