My Baby Chick!

Eggy bond with uncle Karaku

Week later,
Urogi was snoozing but mostly drooling while sleeping from the nest he’s resting on while his egg was being covered under his wings for warmth during the season changes since it was nearly the beginning of winter. The breeze was getting colder out just when he actually laid his baby bird and had gone all protective of them. Making sure no predators are trespassing on the property, the cabin.
Not having Karaku nor Sekido closer to his egg.
Making sure the egg is warmer and safe.
That's how he went on being a good dad and keeping his egg safe, Not knowing that Karaku quietly sneaked his hands through the massive feathers and gently grabbed the egg as he pulled it out quickly and took off running.
What on earth is this pleasure demon up to?

Time skip
Outside near the cabin, by the cut log where Karaku was seated but held the egg while looking at it, scent it as a living being inside of the shell. But did noticed it was growing a bit faster, unlike human children, since this one is a demon. They grow faster but still have to develop their body into good condition such as hearts, muscles, bones and fingers.
He held it closer, placed his ear to heard heart beat. Smile, "strong heart, kid..." He whispers then holds the egg closer to him and heads inside since he noticed the horizon was turning into dawn.
Carefully place the egg back with sleepy Urogi then start to close the door and cover the windows from any sunlight entering the house.
Outside, the sun rises from the mountains. Little did they know that the egg started to shake a bit, and a kick was heard from the shell with claws.
Another kick of the second leg which the little person was trying to break free. Soon enough they were walking on its feet, running away in a rush while their dad was snoozing.
The egg was running on foot towards the visible sunlight unaware of the danger it is.
It trips and drops into the ground as the...... little baby girl with small wings with the sunlight shining on them. She was rubbing her close eyelids by the bright light but mostly trying to get a clear view as her (e/c) eyes saw the scene of the house. Clean but spotted a bird man sleeping.
She carefully stood herself up from the ground and ran towards him, climbed over the nest and went into his huge wings.
All she felt was warm by her dad, smiling as she went back to sleep but cuddling him. Feeling safe to recognize Urogi as her daddy, but....
In the first existence, little (Y/N) was the first demon to stand within the sun.....

Taisho Era Secret
-(Y/N) has wings and an eagle appearance.

-Karaku already loved his little niece, he figured out it was girl.

-She has no connection to Kibutsuji nor his curse since she was biological born from Urogi.
