(Kai POV)
The first thing I remember is getting a load of information inside my head, breathing techniques from one of my favorite manga: Demon Slayer. It was this very cool story about a charcoal seller named Kamado Tanjiro who became a Demon Slayer in order to find a cure for his sister and kill the progenitor of Demons: Kibutsuji Muzan.
It was a very action packed story with lots of emotional moments and worldbuilding that I loved, even though every time I started liking a character too much they died (RIP Rengoku) so, yeah, it was a bittersweet story but I still loved it.
The second thing I remembered was a fact about how I would be reincarnated: Life begins at conception, which meant that the very moment the eggs were fecundated a small, very miniscule, soul would be created within the egg as the body's being generated.
Which meant I was not going to be "stealing" someone's body or something like that, I was also informed that this family I was born into craved a child for a LOOOOOOOONG time so it's a win-win situation, I am reborn and they get a son, everyone's happy.
Unfortunately that also means that I'm waiting here in this darkness, good thing because God knows what's happening inside here, so I have to wait for 8-9 months until I'm born, speaking of which I'm starting to fee sleepy so...goodnight.
(9 Months later. 3rd POV).
In the Ariake Minna Clinic a woman is giving birth, her name's Kobayashi Kaia, a 28-year-old woman with black long hair and eyes. Gripping her hand is her husband Daimon Masaru, a blue-haired man with celeste eyes.
The pair, though young, had wanted to have a child of their own for these past 2 years, the issue however was that both of them were sub-fertile, meaning that the chances of them getting their own child were very slim.
That was until months back when they tried a certain "product" that just got legalized to increase fertility, the bed crumbles, the sheets got moist and both Masaru and Kaia were a mess after the deed but it was worthy.
Kaia was pregnant.
For the past 9 months she did as many "process" to keep her unborn child healthy. She'd get plenty of rest each day, eat a proper diet avoiding seafood and even do a level of exercise to keep herself fit.
Masaru also helped, buying special pillows for Kaia to sleep well, home cooking all her meals and give her several massages to relax her strained muscles.
Overall, a W pregnancy for Kaia, minus the morning sickness, the cravings, the emotional shifts, that time she thought Masaru had a spider on his back and she smacked him with the broom.
You know, normal pregnancy stuff.
And now it was the time to give birth, the beauty of nature in which the love of 2 humans culminate in a pure being known as a baby. Which is meant to be loved, catered to its every need and of course---
"AAAAAHHHHHHHHH!!!" Kaia screamed in pain.
Right, the whole "birthing" process is extremely painful and in some cases unbearable, guys are lucky the biggest shit's coming from their holes are either kidney stones or shit.
No but seriously, imagine the fear of pregnancy, like, you're basically living for 2, or more depending of your luck, and one fall equals the death of that cherished child(s) in your belly. Worst part is that when you finally get to "meet" it personally, the pain is so much you might start contemplating your own mortality.
Let's not even talk about post-partum depression and all shit.
Where were we? Oh, I babbled so long Kaia finished birthing 20 minutes ago.
"He's so...beautiful..." Kaia whispers and pants as Masaru holds the baby near her.
"How are you feeling?" Masaru asked worried.
"Not that...bad, I feel...quite relaxed…actually..." Kaia.
Masaru handed the baby to Kaia and she hugged him as tight and carefully as she could muster.
"Isn't it a bad signal when the baby doesn't cry?" Masaru whispered to the doctor.
"Well, not necessarily a bad sign, especially if the baby is breathing well, has good color, and normal muscle tone, which he has. He probably got extremely lucky and didn't inhaled any clear fluid. Not just that but he's also taking big breathes of air, which is helpful at this stage so, I wouldn't worry about it." The doctor answered.
"Thank you so much, I won't be capable of thanking you all for what you did." Masaru bowed a little to the doctor.
"No need, it was our job and pleasure to bring a life into this world. You better enjoy these first minutes, preliminary exams will be conducted in 30 minutes." The doctor informed Masaru.
"Thank you." Masaru rapidly went back to Kaia and both of them started to coo the baby up.
(50 minutes later.)
The doctors finished the post-partum exams on the baby and Kaia was still weak so she would stay in the hospital, Masaru in the meantime is watching his son sleep peacefully in the nursery.
He couldn't stay all the time with his newborn though, he had to finish writing some papers for his birth certificate and all.
Name: Daimon Kai. Date of Birth: May/13/2023 (Guess the Easter Egg on this date)
Now, like every good father he has to prepare their house to be 100% baby-proof before coming back to the hospital for whatever need Kaia and Kai will need.
What Masaru didn't know was that his son was just seconds away from waking up.
*YAAAAAAIIIIIICH*
Starting now.
Baby Kai let out a small yawn and slowly opened his eyes.
'Man, I've been TIRED. Where are my parents? Oh, I'm in the nursery aren't I?' Kai thought.
Kai's been "conscient" ever since he was in the womb, he couldn't see, hear or even understand what was happening around him all the time and sometimes he would doze off for days.
Naturally this wasn't healthy to him but Wexof was kind enough to give him the playlist to Demon Slayer's whole anime, including the movies that hadn't been released by the time of 2/01/2026.
Of course there's so much Demon Slayer one could watch before going crazy but Kai is quite the resilient guy, he didn't break, he took this solitude as a chance to plan out his next move.
He knew what he wanted to be, he just needed to understand his current situation, as such he got the habit of talking to himself. The rest of the time he would rewatch Demon Slayer for the sake of seeing how to move properly with the techniques.
I mean, those were his "cheats" anyway, he might as well learn properly how he should move around instead of spraining his limbs.
Then there was the fact about his body, he's a baby for Christ's sake, his underdeveloped lungs would burst before he could do anything, it's not like he's Yoriichi Tsugikuni, A.K.A The Human Most Loved by the Gods.
And finally something that he really wanted/needed…friends. Full disclosure, Kai is quite the social person, he enjoyed having people around him except on very few occasions, he enjoyed the company of others so much and so did the others to his.
A/N: On Watanabe Kai's death-day three different neighborhoods mourned his death and the robbers he stopped "somehow" ended up paralyzed from the waist down after they were taken into custody, allegedly done by a detained criminal.
Adding on the fact that he's basically spent months talking to himself alone in complete utter darkness might not be healthy at all.
He still look the same he did before reincarnating but his hair is blue with a flick being black and his eyes are celeste.
As Kai's currently contemplating his own newfound life he gets sleepy again, so, like any other normal baby he falls asleep relatively easy.
A few days pass and Kaia, Masaru and Kai can finally go home.
'Huh, healthcare here's really good.' Kai thought as he played with his hands.
He's been moving somewhat from one side to the other for two reasons, A: He wanted to see how much a conscious baby body can move, and B: A baby that doesn't act like a baby is creepy and suspicious.
"Aww~ look, our little Kai-kun's getting restless." Kaia cooed as she took a picture of Kai moving his arms.
"Don't worry Kai, super dad will bring us home in no time." Masaru "prepared" himself as if he would bring the car to high speeds but he was just roleplaying, he even made the VROOM sounds.
'I really like these two.' Kai smiled.
"*GIGGLE*" Kai.
These last few days Kai met his new parents, at first he felt a tad awkward due to the love he had for his previous ones but he realized something. Watanabe Kai loved his parents till the end and they loved him as well.
Therefore, Daimon Kai ALSO has to love his parents just as much as they love him and boy do they love him. They coo at him, carry him gently, wash their mouths before talking closely to him to prevent bad breath.
That small feeling of awkwardness was slowly being erased by the newfound love he feels for his parents. This doesn't mean that they're better or that they've replaced his previous ones, it just means that he regards them as his true parents just as much as the first ones did.
As a baby, Kai has 3 main missions: 1. Eat. 2. Sleep. 3. Don't die.
Pretty simple missions since he's fully conscious and all, the issue now is his pride is about to be shattered.
*SNAP*
"GOOO~"
*SNAP*
"GYAAA~"
*SNAP*
"WOOOO~"
Kai was "posing" in different positions as his mother took pictures of him in his baby pajamas. Such humiliating feeling must really be crushing his poor mature soul—
'Heh, this is actually quite fun, it's like Halloween but with no candy.' Kai.
A/N: Kai likes to roleplay while wearing different clothes so, yeah, this isn't that bad to him.
Nevermind, the guy's invincible.
As night arrived he was placed in his cradle in his parent's room, he looked at the toy stars dangling in front of him and smiled.
'This life is going to be nice.' Kai thought as he drifted into slumber.
Oh…how fucking wrong is he…
