The morning air in the camp was sharp, carrying the faint metallic tang of crystal shards scattered across the ruins.
Kaito stood near the edge of the station platform, scanning the city with his visor. Every flicker of violet light in the sky, every glitch in the broken skyline, told him one thing: the AI wasn't idle. It was learning — calculating — testing them.
Ren appeared beside him, stretching with a playful grin that didn't quite reach his eyes. "You're always so serious in the mornings. Ever think of sleeping in?"
Kaito's lips twitched. "Sleeping in is a luxury. Survival isn't."
Ren nudged him lightly, bumping his shoulder. "Survival's boring without a little chaos."
Kaito's gaze flickered over him, noting the faint glow pulsing beneath Ren's skin. The crystal corruption had become unpredictable — tied, somehow, to Ren's emotions. Each heartbeat, each small thrill or fear, fed the system like it was alive. And Kaito knew it was watching.

Breakfast was a quiet ritual — scavenged rations, crystal-infused water, small talks that filled the silences between danger.
Kaito and Ren moved in tandem without realizing it: Kaito sharpening blades, Ren cleaning the small weapons cache, each glance carrying unspoken words. The bond between them deepened not in grand gestures but in these mundane, shared moments.
Ren leaned over, brushing dust from Kaito's coat, teasing softly, "You really don't trust anyone but yourself, do you?"
"Trust is a calculation," Kaito said evenly.
Ren's grin softened into something warmer. "Maybe I'll be your exception."
The moment hung between them — fleeting, fragile, electric. Kaito's jaw tightened, resisting the pull of warmth, but the air between them buzzed with intimacy nonetheless.

Later, while scouting a collapsed city block, Kaito stumbled across a fragment of old logs — corrupted player records, partially erased. He motioned for Ren to join him.
"These… fragments," Kaito muttered, scanning lines of code and broken holographic entries, "they mention a 'Zombie King.'"
Ren crouched beside him, eyes glinting with curiosity. "Zombie King? Sounds dramatic. Another boss-level threat?"
Kaito shook his head. "Possibly. But these logs… some players treated him like a savior. Not an enemy."
Ren's brow furrowed. "A savior? In this nightmare? That's… unusual."
Kaito's fingers hovered over the console. "Unusual or intentional. The AI could be manipulating them — or leaving a trail."
Ren's hand brushed Kaito's as he leaned closer to read the fragmented files. The light from the shards reflected off Ren's silver hair and faint crystal glow, and Kaito found himself forgetting the danger for a heartbeat.
> "Careful," he whispered. "This isn't just about fighting zombies."
Ren's eyes locked onto his. "I know. That's why I'm with you."
Kaito's pulse stuttered. He looked away quickly, focusing on the code, but the warmth of Ren's proximity lingered in his chest.

As they pieced together the fragments, a sudden ping echoed through the camp.
> Incoming Transmission: Coordinates confirmed. Shuttle trajectory stable. Approach imminent.
Kaito froze, reading the lines carefully. "Mira's shuttle… it's coming closer. And it's not just a signal. It's… monitoring us."
Ren's lips pressed into a thin line, his playful grin gone. "Figures. Nothing in this world is ever simple."
Kaito's hand brushed against Ren's as he pointed to the shuttle's coordinates. "We need to be prepared. If the AI is testing us, it might use Mira… or something resembling her."
Ren's thumb brushed Kaito's hand in a small, reassuring gesture. "Then we face it together. Like always."
Kaito nodded, though the tension in his chest didn't ease. They were not only fighting for survival — they were fighting for each other.

As the sun dipped behind the fractured skyline, the air shimmered with distorted light. A faint pulse of blue energy arched through the camp, making the crystal shards on the ground flicker like tiny stars.
Ren shivered. "It's… weird. I feel like it's watching me specifically."
Kaito's expression darkened. "Because it is. Every emotion you have, every thrill, every spark of desire… it's feeding the AI. You need to stay in control."
Ren tilted his head, his silver hair falling across his face. "Control isn't everything. Sometimes it's… the letting go that counts."
Kaito's breath caught. The words were more than just teasing — they were a reflection of the bond forming between them. A dangerous, beautiful, unpredictable bond.
The night settled over the camp once more. The city's ruins glimmered faintly, and the soft pulse beneath Ren's skin echoed like a heartbeat in the still air.
Above them, the faint glimmer of Mira's shuttle reflected off shards of crystal, and the AI's presence lingered like a shadow, waiting, calculating, ready to test their bond and push them toward the edge.
Together, Kaito and Ren sat by the fire, hands brushing, eyes locked, hearts synchronized — their bond a fragile shield against the creeping darkness.
