The courtyard of the Ubuyashiki Estate was unusually tense that afternoon—tense enough that even the cicadas seemed to quiet, as if sensing the sharp edge of conflict in the air.

Sanemi Shinazugawa stood at the center of it all, one hand gripping the wooden box slung over his shoulder, knuckles white with agitation. Tanjiro struggled against two Kakushi on the ground nearby, shouting hoarse pleas for them to stop, his voice cracking with desperation. The Hashira ringed the space, scattered but attentive—Kyojuro bright-eyed, Giyu unreadable, Mitsuri already halfway to tears. Even Obanai’s serpentine gaze narrowed with the promise of violence.

And at their head, blind yet somehow seeing more than any of them, Gyomei Himejima knelt in quiet prayer—until the shift in the wind brushed against his ear.

He froze.

A heartbeat later, every Hashira felt it.

A subtle drop in temperature. An almost inaudible hum, like steel vibrating in moonlight. Something ancient. Something deadly. Something you.

“…She has returned,” Gyomei murmured, voice thick with reverence.

Sanemi scoffed. “What, the Moon Princess finally crawled back—?”

He didn’t finish.

Because your presence washed through the courtyard like the slow eclipse of a rising moon—silence swallowing sound, calm swallowing chaos, power swallowing Sanemi’s bravado.

You appeared behind him without so much as stirring the dust.

Your haori whispered in the faint breeze, silver arcs of moon phases glinting faintly as if lit from within. The long sleeves of your uniform drifted like soft banners, pale crescents embroidered across them. One hand rested loosely at your side, the other gently touching the silver-white tsuka of your Nichirin blade.

Calm. Quiet. But carrying an unmistakable promise.

“I suggest,” you said softly, your voice level but somehow colder than ice, “you drop the box… and walk away, Wind Hashira.”

Sanemi stiffened.

He hadn’t heard you approach.

None of them had.

The air felt heavy now—dense, like the moment before a thunderclap. Even Giyu’s posture shifted slightly, recognizing a threat only a fellow Hashira of your caliber could manifest so effortlessly.

“Yer stickin’ your nose where it doesn’t belong,” Sanemi growled, gripping the box tighter instead of releasing it.

You didn’t move. You didn’t even truly look at him. You simply stood there, radiating the effortless, overwhelming presence that belonged only to the strongest of the ten Hashira—an aura so refined it bordered on divine, as if moonlight itself had taken human form.

“Sanemi,” Gyomei’s voice rumbled. “This is unwise.”

But he wasn’t listening.

He never did.

You took one single step forward—barely the length of a breath—and still, every Hashira felt the pressure snap tighter around them. A phantom arc of lilac-tinged silver shimmered at your feet, a hint of your Moon Breathing leaking into existence like mist.

“Nezuko Kamado is under Ubuyashiki-dono’s protection,” you said evenly. “And she has harmed no one. Release her.”

Tanjiro nearly sobbed in relief at the sound of your voice.

Your eyes never left Sanemi, even when he tried to turn his back toward you.

“Or,” you added quietly, “I will make you.”

Your hand never fully gripped your blade.

It didn’t have to.

The Moon Hashira did not need to draw steel to remind the world why even demons whispered your name in fear.

Sanemi felt it—felt that if he moved even an inch more, if he so much as breathed wrong, the full weight of your Fifth Form: Full Moon Bloom would bloom through his spine before he even registered the strike.

His pulse thundered. His grip trembled.

And finally—

The box hit the ground with a dull thud.

Sanemi stepped back with a scoff that didn’t hide the tension knotting his shoulders. “Fine. You wanna deal with the damn demon? Be my guest.”

You exhaled softly, the air loosening with you.

Gyomei bowed his head toward you—a silent greeting, a silent relief.

“Welcome home,” he murmured.
