You were a Hashira — one of the strongest among the Demon Slayer Corps. Ever since the crow screamed, “Attack on the Ubuyashiki Estate!” every Hashira moved out without hesitation, blades gleaming under the night sky.

You were alongside Muichiro, charging at full speed. No one knew who stood in the middle of that burning chaos—until Tanjiro’s voice broke through the noise. “It’s Muzan!”

Every blade pointed toward him. Every heart burned with vengeance. And just as you all dashed forward… the ground trembled. Doors burst open beneath your feet, swallowing everyone whole.

The Infinity Castle.

You landed hard, the impact sharp enough to rattle your bones. Around you—Muichiro, Genya, Sanemi, and Gyomei. Your left eye throbbed with pain, blood blurring your vision, but you forced yourself to stand. There was no time to rest.

The battle was merciless. Every strike echoed with desperation. Blood, sweat, tears—they all mixed into one.

Muichiro’s blade was stuck deep within Upper Moon One’s flesh. He couldn’t move, his small frame trembling. You sensed the killing intent before it even reached you.

Without thinking, you rushed in—shoving him out of the way. The attack landed… but on you. Your arm was gone, pain spreading like wildfire.

Still, you smiled through it. You’d saved him.

But Muichiro… he was fading. The blood loss, the wounds—it was too much. His breathing slowed as you cradled him in your remaining arm, pulling him close.

Muichiro: “Iviana…?”

His voice was faint—barely a whisper—but you heard it. You always did.

You opened your one good eye, smiling weakly. The world around you was collapsing, but in that moment, nothing else mattered.

“Till death do us apart,” you whispered back.

Too young. Too soon. But at least… you’d die together.

But no.

In this new—next life. A modern life—peaceful. Perhaps fate had enough pity to give you both the life you were denied.

A life without death. Without bloodshed. Without fear.

The world was brighter now—no scent of blood, no shadows of demons lurking at every turn. Only the scent of rain on pavement, the hum of cars, and laughter echoing faintly through crowded streets.

You lived a normal life this time—an ordinary girl with messy hair and sleepy eyes, always running late for school, always humming under your breath. You didn’t know why the sound of wind brushing through trees sometimes made your heart ache.

Across the same city, in another quiet neighborhood, a boy with silver eyes leaned against his bicycle, watching the morning sun rise between buildings. He didn’t know why his chest felt heavy whenever he looked at the clouds—why he sometimes dreamed of a forest blanketed in mist, or the faint glimmer of a sword he never held.

And one day, by chance—or perhaps, by fate—you crossed paths.

It was at a crosswalk. The light turned red, your eyes met for the briefest moment.

Neither of you knew each other. Neither remembered anything at all.

Yet for that single second, something in your hearts stirred—a strange calm, like a memory that never was.

Then the light turned green, and you both walked past each other.

Different lives. Different times. But the same souls.

Fate didn’t let you remember… it just made sure you met again.
