Summary
“You’re too skinny.”
That’s the first thing the boy with peach hair and the scar says to him.
Is that any way to greet someone?
The words in his head are Tsutako’s. She always reprimanded him for being too blunt, for lacking manners, for forgetting to be polite.
It seems someone forgot to teach this boy that lesson as well.

“Does it…hurt?”
Genya looks down at his hands, away from Tanjiro’s gaze. His burgundy eyes are curious, sure. But mostly they look worried. About him. As if he deserves it. He can feel the weight of that imploring stare on his skin.
He considers the question.
Does it hurt to change into a demon?

Summary
“What the hell are you looking at!” The words rip from Inosuke in a shout that startles the birds in the trees and sends them flapping away in a chaotic frenzy.
The yellow-haired kid’s face pales and his hands come up in front of him protectively. “That,” he yells back, his voice annoying. It’s full of trembling and cowardice. “That thing you wear, why do you have it?”
His mask? That’s what this is all about??

Summary
A thousand years, not once in a thousand years, has one of his progeny proved their competence. They wile away their nights, glutting on humanity, falling beneath the blades of those roaches, vermin, that call themselves “Demon Slayers”. And through it all, Muzan has been so very tolerant of their ineptitude.
And all for what?

Summary
It’s a mirror. He’s only looking at himself, Giyuu reassured himself. But standing there, only a foot away, separated by nothing but a pane of one-way glass, it felt like the subject’s eyes—lavender eyes—were burning straight into him. And Giyuu, because he couldn’t help himself, stared back, feeling like he could hardly breathe.
The scars were deceptive.
Their subject was beautiful.
Then his nostrils flared.
“I can fucking smell you, asshole,” he growled. The subject leaned forward, until his nose must have been almost against the glass. His voice dropped to a low rumble. “If you’re going to stare at me like I’m some goddamn sideshow freak, you might as well get your ass in here and let me return the favor.”

You’re special, Managi, his mother told him.
Special. Special. Special. Drummed into his head over and over and over, loud enough to drown out the insipid whisperings of the rest of this fish-mongering village.
Still, Managi heard it anyway.
Strange.

Summary
Lavender eyes flick back to Giyuu’s and hold. There’s fire in them, blazing hot enough to burn. His voice turns low and dangerous, and in another setting Giyuu thinks all of this would be really damn sexy. But then he focuses on what Sanemi is actually saying to find that the message is decidedly not sexy at all.
“If you don’t get back to work,” Sanemi promises, “then I don’t give a shit how much you’re paying me; I’ll leave your jock ass here to flunk out of algebra and get kicked off your damn team.”

“What happens after we pass Final Selection?”

Summary
“He’s alright,” Sanemi gruffly says, folding his arms, pointedly watching the Sound Hashira now. He can feel warmth on his cheeks and hopes it’s not as obvious as it feels.
Shinobu laughs, a bright sound, a little sharp, a little incredulous. “Alright, Shinazugawa? Tomioka’s defensive technique is flawless.” She glances up at him, then looks back out the window. They watch the match in silence for a moment before she speaks again, softly, almost as if to herself. “Water breathing is fundamental, easy to learn. But mastering it? Expanding it?” She sighs, then shakes her head and turns to go about changing the linens on his bed. “Tomioka Giyuu is more than alright, Shinazugawa.”

Summary
“So what, you don’t have a better way to spend Christmas Eve than sitting by yourself on a park bench…?” The edges of his words are clipped in a way that says he’s not really surprised (this is Giyuu, after all), only disappointed.
But then, that’s not really fair, is it?
“You don’t have a better way to spend Christmas Eve than walking by yourself through a park?” Giyuu asks, pulling his gaze away from the lights to look up at Shinazugawa. His expression hardens. The snow falling lands in his hair and vanishes, blending perfectly with the silvery locks. The lights make him glow softly.
He’s very pretty, too.
