My Baby Chick!

Humanity within the Supernatural Beings

The confused eagle demon was getting really uncomfortable with this male harpy? But she senses him as a demon, like herself.
Urogi was crying so uncontrollably that he at last found his baby bird after thousand years of no trace but her bloody feathers were left behind at the woods he assumed she was killed by a slayer that Akaza claimed under his statement. There wasn't any proof but the grieving father couldn't think but his entire personality changed the moment he wasn't able to process mourning over his daughter.
“I’m so sorry, baby girl! I shouldn't have left you when I wasn't able to protect you well enough! But your uncles are gonna be happy that you're alive and coming home right now!” His voice sounded so broken while crying as he kept on holding the frightened demon girl.
She couldn't move but only froze out of fear. Why can't she tell him that she wasn't his daughter, but hearing him sounded so hysterical but happy as well.
(Y/N) was about to speak until fire circular rings cut between them two so fast, Urogi screeching out of pain because his claws were disarmed from the horrible slice. Burn possibly through his blood wound meanwhile she felt unharmed but scared of the fire.
Roughly arms wrapped around her waist then she felt herself fall under someone else's hold.
The sober Shinjuro had just come here unexpectedly and his body moved to recuse the demon girl, like he doesn't care about crossing with one of the Upper Rank 4 demons knowing it ain't his real body.
As he landed on the ground into his feet without the demon girl in any harm as he ran faster on. While she was being carried away, see the male demon crying out of pain as he regenerated his burn wounds.
Urogi struggled on healing his wound but glared hatred at the bastard kidnapping his child away from him, but it didn't stop him as he flew light-speed towards both of them.

Back at headquarters
Senjuro was interrupted awake by the loud door that had him fall onto the floor,
“Rengoku! Get dressed, now! Demons spotted in the east village!” Voice said through the door.
His eyes widened.
He hurried himself up, grabbed his kakushi uniform but scared as if he hoped it wasn’t- He paused for a moment, realizing. Could it be (Y/N)?
Bust the door open and run on foot while buttoning his uniform, praying it isn't his friend, his crush. Suddenly he felt his face become hot redder all over his cheeks to the ears but arrived at the hospital room. He forcibly opens the door wide, gasps at the sight, finding no one here but a few missing feathers on the bed and the window open wide.
It was bad! But he didn't want to believe she was going rogue. Senjuro refused to accept that false claim but dressed him and might do something entirely stupid.
.
.
Go out and find his demon friend on his own.

Time Skip
Shinjuro grips his katana sword tightly while defending himself and the shocked demon eagle. It was very fortunate for him to bring along his weapon of death for a time like this when he left for unknown reasons after Senjuro went with her.
Never came home, was signed to give up drinking and other things.
Now, it was really difficult to kill the demon, far more powerful than ever, it kept on regenerating itself leaving the sober hashira into more scratches from Urogi’s talons clawing him whenever he attacks while Shinjuro dodged or used his blade for defensives.
Another screech was coming up from above the sky, immediately jumping further that Urogi hit the ground but cracking underneath his talons.
His rage yellow hues faced at the former Hashira, father vs demon father were at war with each other when this bastard dared touch his little baby chick. He flew straight at Shinjuro while he prepared to use his flame technique even if it was useless to not fight against the real body.
Meanwhile (Y/N) was in total shock that she wasn't responding or unable to assist Shinjuro against that bird hawk demon.
His claim on her belief he found his daughter, herself. It couldn't help but possibly it was true since they are birds in one feather.
Heard more screech from the demon, faced at the adult men battling at each other but noticed how the poor former flame hashira was trying to get an opening from the hawk demon.
It was like he planned on killing the mortal man, her body wouldn't move at all on wanting to stop this. It's not like she didn't want to rescue that man, having this unknown emotion that locked her legs from responding to any of her nerves connected to the brain, was totally frightened.
Her eyes were tearing as Urogi's terrible screeching echoed through the entire forest while Shinjuro decided to go reckless move,
“Flame Breathing Second Form…” Everything was in slow motion with flames of vertical slash in an upwards motion heading directly at Urogi's neck, no way of dodging it as he could feel the heat about to decapitate him…… soon his head flew into the air without his body,

“Rising Scorching Sun!” Shinjuro felt like he was relieved but gasped that the body was moving towards him fully.
He couldn't get himself to do another breathing technique on time.

An massive hurricane wind had blasts blowing him along the body further away from each other, while in the air, Urogi's head was not disintegrated into ashes but his golden eyes spotted something shocking.
.
.
.

(Y/N)’s wings were bigger than average as she caused the wind blasts then flew straight at Shinjuro, quickly grabbing him into his shoulders. Like grips her talons into his kimono’s clothing, as she used her strength in carrying the overgrown man into the sky.
Getting away from the demon, since she didn't think that it was easy to kill that man but needed to get herself and Shinjuro into safe territory before the hawk demon might regenerate himself again.

Meanwhile Urogi's body flew into the sky, grabbed his head and placed it onto the neck, as his flesh attached itself quickly. His tears were falling from his cheeks, once again he was in sad mourning at this heartbreaking experience from having to witness his child go with that man rather than him.
Didn't understand? Why would she go with a stranger than her dad whom he loved more than anything in the world?
What happened to her after so many years? Or what did Akaza say about her being killed? Just by what slayer? Or was it a lie?

By the time both Shinjuro and (Y/N) spotted few Kakushi members approaching from the hills as they were running but importantly two other hashiras, Sanemi and Giyuu with them?
Couldn't believe it but she was happy to see her favorite water Hashira friend, she accidentally dropped Shinjuro into the ground that he grunted in frustration but witnessed her behavior as she tackled Giyuu into a hug.  Sanemi almost got his katana out thinking she was going to attack but instead, hugged attack into the guy he disliked.
But had herself transformation into child appearances as a teen, she felt scared but happy at the same time while hugging the depressed water Hashira.
Giyuu didn't push her away or anything but lightly patted her head.....
This was weirding out the Wind Hashira and Shinjuro looking confused while the Kakushi members were treating his wounds, now everything seems too strange.
Just having to see this friendly demon, not harming living flesh but only giving out hugs or cat behavior towards fellow generation Hashira.
Guess he thought wrong about her, when Senjuro said she wasn't dangerous.
"Father?"
Senjuro says from behind the Hashiras and (Y/N) as he directed had his attention on the man, whom he thought wasn't father to him nor Kyojuro all of their lives.
"Senjuro?"

Taisho Era Secret
- Giyu likes (Y/N)'s hugs, especially her wings felt comfortable as cloud. He sometimes sees her as Nezuko but more like his older sister, Tsutako.... If only maybe when she was younger.

-(Y/N)'s wings were powerful to developed her uncle Karaku's wind demon arts, but she hasn't her demon arts shown yet. Until a few chapters.

-Akaza knew what really happened since (Y/N) vanished but couldn't tell because....he was given orders.
