The three looked at her with different levels of shock. The black haired twin simply pointed to a place, where Ochako dropped it with a heavy thump.
"What is your breath?" The white haired twin asked.
Ochako tilted her head. Maybe 'breath' was their way of looking at quirks? Nevertheless, she answered, "Gravity."
Zero Gravity to be more specific, but I've been thinking...
Tanjiro made an awed noise. "Wow! My breath is water, I've never heard of a gravity breath! Who taught you?"
"Um, no one?" Did her gym sensei's count? " I've had it since I was four."
The incredulous looks(and the mutter of 'What a promising Demon Slayer in training..' )she got told her that was not the right answer, so she decided to just go to the forest. "Well, I got what I wanted to know, I guess.. Tanjiro, are you coming?"
She looked over her shoulder at her new friend, her bells jingling merrily, as if calling him over.
"Ah, yeah!"
The two walked in silence, the jingling of bells and shoes crunching the dirt the only sounds of the night. Suddenly, two things showed up. Ochako gulped down a gasp.
"Demons.." Tanjiro hissed under his breath. Ochako stilled. These disgusting things were demons. Something about these things, seeing them argue about which one they were going to eat, which one got the most, made something stir in her. Something she never felt before.
Hate.
The demons charged at the two allies, and Ochako didn't hesitate to bring her foot around in a roundhouse kick, severing one of the demons head from it's body without any delay with strength she didn't know she had. Her hatred for these beings, sudden or not, made her so angry thinking about the people it could have eaten. The people with families, the people with people who care for them, gone.
Tanjiro took out the other demon with no problem, using his water breath. Ochako though it was so cool, and couldn't stop asking questions about it. She looked back on the pile of clothes left of her demon when Tanjiro asked where he was, and she felt a surge of pity for the now dead thing.
At the same time, her and Tanjiro both muttered a 'rest in peace' to the two demons.
The two looked at each other with slight surprise, when Tanjiro's face crumbled, and he brought his hand up to cover his nose. "Smell... what a rotten smell... What is that?"
"Sm-" Ochako was cut off by a horrible scream.
"AAUUUUUGGGGHH!" A male ran into view, screaming his head off. "What is that? I didn't sign up for this!"
Ochako felt her breath hitch. A giant green monster stomped into view next, carrying a dead boy by the neck. It had so many arms and was so giant, Ochako wondered how many people it had eaten, but quickly stopped as she felt a familiar nauseating sensation fill her head and stomach.
The monster reached out with one of its many, many, arms, grabbing the boy who was previously running by the ankle. Ochako saw red.
Move. Move movemoveSAVEHIM, GO MOVE!
She did not move.
But Tanjiro did.
In a slice she couldn't even see, Tanjiro severed the demons' arm of with his Fourth Style: Striking Tide, and dropped in front of the now safe(ish) boy, the pieces of the arm(arms?) falling in front and to the side of him then dissapating in a crumbling fashion.
It was that moment Ochako berated herself. What are you doing, Ochako!? You are a hero in training, and now a demon slayer in training, you can't freeze up when something gets to you! You can't afford too!
Mind now cleared, muscles now manipulatable, Ochako released all gravity on herself except on her feet, and immediately felt herself want to rise, her feet holding her down like an anchor.
But that was no problem.
Ochako kicked her feet down, ridding herself entirely of gravity for a moment, launching herself high into the air where she gradually pushed gravity back onto herself and dropped hard as the gravity protested her weight. She kicked her leg up high in an axe kick, and pushed more gravity—that wasn't hers— onto her body, making it heavier and more easy to slice with.
The demon brought a giant arm up right in time to prevent her from reaching his head, and she managed to slice right through it, despite her blade only being five inches tall and connected to her foot.
Ochako landed softly on the ground, gravity lifting from her like a five pound weight being picked up by a body builder.
The demon reached for her, and was getting close enough that Ochako would be able to get all five fingers on him—
"Breath of Water, Second style: WATER WHEEL!"
Tanjiro tore the arm off with a circular saw of water, a beautiful display of the different shades of blue. So beautiful, in fact, that Ochako couldn't be mad that he just ruined her chance to completely destroy this demon.
She was sure she'd have other chances anyway.
The demons eyes narrowed with glee. "Another of my cute foxes have come~"

"A gravity breath?" A man asked incredulously." I've never heard of such a thing."
" Nor have I, father. But she picked up one of the wisteria tree's using it without any strain, and rearranged it. It was almost unbelievable to see." The black haired twin said, chewing the inside of his cheek slightly. "She apparently uses small blades in her sandles to slay demons, using her leg strength and gravity to sever the head from the body. It's remarkable. She could become a Hashira to an entire new breath."
" Indeed she can, Kiriya." The man smiled gently, his scarred face softening as he thought about being able to have another child to take care of. "Indeed she can."
"Oyakata-sama?" A new voice spoke out.
"Sanemi, good timing. I was just thinking of you. Say, you are the Wind Hashira, no?" Newly dubbed 'Oyakata-sama' inquired.
Sanemi furrowed his brow more than it was, though it was impossible to tell due to the lack of eyebrows, and to the fact Oyakata was blind. "..Yes."
"Yes, wind is close enough.." Oyakata muttered to himself. Then addressed Sanemi again. " Is there a 'Gravity' breath style?"
"Pardon me, but a what?" Another new voice rang out.
"Kyojuro is correct. As flamboyant as a gravity breath would be, there cannot be one. Gravity is so flamboyant no one can even defy it, let alone create a flamboyant breath style."
"..what's gravity, again?"
Tengen and Miuchirou are so cute! But a gravity breath.. I wonder how that would work! My chest hurts just thinking if it!
"How sad... No one knew of a knew potentially powerful breath style and it has been for.. how long has this sorrowful child had this breathing style?"
" I believe she said since four years of age, Gyoumei-san." Kiriya said turning his empty eyes to the Rock Hashira.
"... No fucking way." Sanemi said.
"Sanemi!"
"Perhaps we should call an audience with her, then. When we get the chance."
" We should do it now, Shinobu."
"But she is in the middle of her Final Selection, Iguro! We can't possibly take her away from that!" Kyojuro said loudly.
" Yes.." Oyakata said before the Hashira's could get into another argument. "Kyojuro-san is correct. We cannot pull her away from her exam. We can request her later, if she survives. I do hope —if she doesn't survive— there is someone else out there who either learned with, or from, her."

All the Hashira's except Giyuu are children confirmed. They are so childish and loud and Muichirou is a literal what, fourteen years old? Yeah, they are all children. Powerful, powerful chikdren.
Ochako was gripping the tree in the beginning so it doesn't float off. And as for the breath pooling out of the corners of her gritted teeth she was remembering Gunhead's training, and was going into 'Battle-Ready Ochako Mode' where she 'gets that weird look on her face' and her muttering were Gunhead's teachings. And when she was fighting the demons, she unknowingly removed the gravity of the demon, making it easier to behead.
So apparently, the Hashira's haven't seen Inosuke yet, neither has out main leads, no worries, but Inosuke could also be a Hashira, as he created another new Breathing style, the Beast Breathing Style.
