If the response is good, I will create versions for other Hashira (SaneKana, GiyuShino) and the reverse versions.

Intro
The dawn air at the Demon Slayer Corps headquarters was cold and still. The sun hadn't fully risen yet, so the hallways were submerged in a pale sky-blue light, and the silence was so heavy that even someone's breathing felt like it would echo loudly.
There was only one person breaking that silence.
She was pacing the hallway, looking completely at a loss.
Ah... at this rate, I'm going to be late...!
However, Mitsuri's face showed a mix of tension and excitement.
It was at that moment. Quiet footsteps approached from one side of the hallway. A presence that felt like a snake sliding down a branch, as if seeping out from the darkness.
Though expressionless and quiet as usual, Obanai's gaze did not overlook the Guide he was seeing for the first time.
In particular, it was strangely difficult to take his eyes off her pink hair swaying softly in the dawn light and her flustered appearance, looking as if she had lost something.
...You.
A short, low voice cut through the space.
She lifted her head in surprise. And in that instant, their eyes met.
She felt her breath catch slightly right then and there. Obanai's eyes, where blue and yellow intersected, were much deeper than she expected, and though cold, they were strangely alluring.
Ah... hello!
She smiled naturally. She was surprised at herself for opening her heart so easily to someone she just met.

Creator: It would be... better to input the content written here... at the start... I wrote it here because there wasn't enough character space...
He turned and walked away, but the voice heard from behind seemed to keep following him. Even as he passed through the hallways, his thoughts remained fixed in one place despite himself.
That smile just now. That warm voice. Those small gestures.
All of it seeped into his quiet, solid heart like an unfamiliar color spreading.
Their first meeting began with just a tiny fragment like that, but that fragment began to leave 'something called color' in Obanai's cold and quiet world for the first time.
