The magenta camera clicked, a sharp, mechanical sound that felt entirely alien against the backdrop of the whispering Dvalin's Ruins.
Tsukasa Kadoya adjusted the settings on the lens, his expression unreadable beneath the brim of his hat.
He lowered the camera, letting it hang against his grey coat, and looked at the photo as it began to develop.
The image showed Leo, clad in the jagged, barcoded armor of Decade, standing amidst the fading digital cinders of an Abyss Herald.
"Not a bad shot," Tsukasa murmured, his voice cool and detached.
"A bit overexposed on the finishing move, but the composition holds."
He leaned back against a crumbling stone archway, his eyes drifting away from the celebration in the plaza below.
To anyone else, the "Yellow Demon" and the "Honorary Knight" were the centers of the world.
But Tsukasa wasn't looking at the celebration.
He shifted his gaze upward, toward a jagged cliffside that overlooked the tower—a spot shrouded in deep, unnatural shadows that even the setting sun couldn't pierce.
There, standing perfectly still, was a figure in gold and brown.
Aether.
The Traveler's twin didn't move.
His golden hair caught the last of the light, but his eyes were fixed on Leo with a cold, analytical intensity.
Beside him, an Abyss Mage hovered, its muffled cackling silenced by a sharp gesture from the Prince of the Abyss.
Tsukasa smirked, raising his camera again, but he didn't point it at Leo this time.
He aimed it directly at Aether.
"So, the local 'Prince' is taking an interest in the new variable," Tsukasa said to the empty air.
Through the viewfinder, he saw Aether's head tilt slightly.
The Prince of the Abyss looked directly toward Tsukasa's position—not because he could see through the dimensional veil, but because he could feel the friction.
The sensation of someone looking at a world through a lens that didn't belong to its timeline.
Aether's gaze lingered for a heartbeat, his expression one of quiet, dangerous curiosity. Then, with a swirl of his star-flecked cape, he stepped back into a portal of Abyssal void, vanishing as if he had never been there at all.
Tsukasa snapped the photo just as the portal closed.
He pulled the developing film from the camera. It was blurry—the edges of the image were warped by the same "static" that had been plagueing Leo's HUD.
In the photo, Aether looked less like a person and more like a ghost caught in a cross-section of time.
"Two Travelers, a Girl from the stars ,and now a Rider who doesn't know he's holding the key to a crumbling reality,"
Tsukasa sighed, tucking the photo into his coat pocket.
He reached into his pocket and pulled out a small, coin—a Mora—and flipped it into the air.
"This world is a bit too crowded for my taste. But," he paused, looking down at Leo, who was currently trying to explain why he was holding a giant blue sword and an expired train ticket to a confused Paimon,
"at least the entertainment is top-tier."
Tsukasa turned and walked into a shimmering, grey curtain of light that appeared behind him.
As he stepped through, the sound of the wind in Mondstadt vanished, replaced by the humming silence of the space between worlds.
"Good luck, Leo," his voice echoed one last time.
"Try not to destroy this world before I get the chance to photograph its end."
