No one's Pov

Sae stalks the battle that's in front of her. The young demon slayer has been holding off the demon for a good while. Sae determines when is a good time to step in.

The young demon slayer charges in behind the large demon and goes in for the cut with his twin blades with confidence. However, the cut wasn't powerful enough to slice its head off, resulting in his blades breaking. In return the demon swatted the poor kid, knocking him into a nearby tree. The demon proceeded to walk up to the kid and grab him by his head, lifting him high into the air and squeezing him.

This was Sae's chance, she readied her blade, breathing in deep. "Ice Breathing. Ninth form. Striking Blizzard".

Sae stepped into the clearing. Her presence was quiet, graceful, yet commanding.

The buff demon stiffened as the temperature plummeted. Sae's blade flashed once, too fast to follow, and in a single cut she severed the arm holding the boar-headed slayer. He stumbled free, clutching at his chest, gasping for breath as the icy aura enveloped the clearing.

The ground beneath the demon shimmered. A great snowflake pattern bloomed outward, glowing faintly with unatural light. The air snapped, and from every angle, icicles burst forth like spears. They cared into the demon's massive body- piercing, slicing, and shattering its grotesque form into shards of frozen flesh.

The monster let out a strangled screech before its body crumbled into nothingness, frost scattering in the wind where it once stood. Silence followed, broken only by the sound of the boar-headed slayer's ragged breathing.

He turned to her, wild eyes beneath his boar mask. He was silent not just silent as it was replaced with pure awe.

Sae flicked her blade, exhaling a soft mist into the cold air. Her gaze remained on the fading forest, her expression unreadable.

But to him, in that moment, she wasn't just a Hashira. She was winter incarnate- terrifying, pretty, and untouchable.

Sae begins to venture forward to find more demons to take care of. But was stopped in her tracks by the boar slayer calling out to her.

"HOLD ON A SECOND! Fight me, miss snowy woman! You beat that member of the 12 Kizuki! And now, right here, i'm going to beat you. If I can manage that", the boy points to himself with confidence. "That'll make me the most powerful of all"! Sae couldn't help but giggle to herself.

"Haha, I apologize. This isn't a laughing matter, but i'm afraid that was not one of the Kizuki. It seems you need to train more". Sae gave him one of her famous smiles as she grabbed some rope undoing the loops.

"WHAT DID YOU SAY TO ME"! The boy yelled.

"Could you not tell? Sure he's strong for someone of your rank, but surely you knew". Sae replied sweetly.

"OF COURSE I DID! For your information, it was Tanjiro saying he was one of them. I was just repeating what he said to me earlier". Sae paused. Thinking back to the boy named Tanjiro. Sae didn't bother listening to what the boar-headed slayer way saying as she grabbed some rope.
