The copper smell didn't just linger; it owned the room.
Kael watched the rhythm of Sera's throat—a frantic, bird-like pulse that was stuttering.
Every time she exhaled, a tiny spray of pink mist escaped her lips.
Her eyes weren't focused on the rusted crates or the jagged ceiling anymore.
They were fixed on a point somewhere beyond the rock, staring at a horizon only the dying can see.
The interface in his mind didn't have a "Save" button.
There was no shop window offering a miraculous Elixir of Life for a few credits.
Just that cold, digital apathy.
[VITALITY: 6%... 5%...]
[ESTIMATED TIME TO CESSATION: 03:12]
"Hey." Kael's voice cracked, sounding small in the vast hollow of the abyss.
"Talk to me. How do I fix this? You're the one with the Rank D badge. You've seen this before. How do I stop the leaking?"
He was shouting at the silence, at the flickering blue screens, at the universe that had seen fit to give him a sword made of bone but no way to mend a broken girl.
Sera's head lolled toward him.
A faint, jagged line of red ran from the corner of her mouth into the dirt.
She let out a sound—not a gasp, but a dry, rattling chuckle that made Kael's skin crawl.
It was the sound of someone who had already made peace with the reaper and found him to be a boring conversationalist.
"You think I'm a goddess?" she whispered, her voice a ghost of the rasp she'd used earlier.
"You think I have a secret technique for putting the life back in the bottle? There is no 'how,' Kael. I'm just an ex-Cavalier who picked the wrong hole to hide in."
She shifted, and the screech of her dented breastplate against her ribs was nauseating.
Her hand, trembling like a leaf in a gale, hovered over the puncture in her steel.
"The armor... it's the only thing holding the pieces together. You want to see the truth? You want to stop the blood? You have to take the armor off. Remove the plate."
She let out a wet laugh that turned into a grimace.
"But the second the air hits the wound... the pressure goes. And then? It will gush. The end. That's the price of the abyss, kid."
She closed her eyes, her fingers sliding off the armor to rest limp in the dirt.
She wasn't fighting anymore. She was settling into the cold, letting the darkness claim her.
She looked peaceful, and that was the most terrifying thing Kael had ever seen.
"The end."
The word echoed in Kael's mind, vibrating against the walls of his skull.
It was the same word Darius had used when he pushed him.
It was the same word the world had whispered to him since the day the Ruin Zone opened.
The end.
A sudden, white-hot surge of fury erupted in his gut.
It wasn't the heroic heat of a savior; it was the ego of a man who refused to be told 'no' ever again.
He hadn't survived the fall, the Wolverine, and the betrayal just to watch the only person who stood with him turn into a memory.
He didn't care about the risk. He didn't care about the "logic" of a Rank D warrior.
"I don't believe in 'the end,'" Kael hissed.
He moved. His knees protested, his muscles screamed, but he crawled across the dirt until he was hovering over her.
His shadow blotted out the sickly green light, swallowing her.
He reached for the leather straps on her side.
"What... what are you..." Sera's eyes snapped open, a flicker of genuine terror piercing through her exhaustion.
She tried to shove him with her good arm, but her hand was a trembling leaf.
"You idiot... you'll just speed it up... the blood will... we'll both drown in it..."
"Then we drown," Kael snarled, his fingers moving with a frantic, savage precision.
He wasn't gentle. He ripped at the buckles that had survived a hundred monster encounters.
He tore through the charred leather and the bent metal pins. He didn't see a woman; he saw a problem that needed to be forced into submission.
The final strap snapped.
Kael braced himself and heaved the heavy, dented breastplate away.
The metal hit the stone floor with a clanging echo that felt like a funeral bell.
For half a second, there was a vacuum. Then, the horror began.
Without the mechanical pressure of the plate, the wound—a jagged, triangular puncture right where her ribs met her stomach—gave way.
It wasn't a leak. It was a flood.
The hot, metallic scent filled the small room instantly. Blood jetted out, soaking Kael's hands, his chest, his face.
It was warm, terrifyingly hot, and it pulsed in rhythmic spurts.
Sera's back arched off the ground, a silent, gurgling scream trapped in her throat as her blood pressure plummeted.
Her face went from ashen to translucent in a single heartbeat.
"No!" Kael shouted.
He didn't have a bandage. He didn't have a plan.
He slammed his right palm directly into the hole.
He didn't just place it; he leaned his entire body weight into her abdomen, pinning her to the cold floor with the strength of a drowning man.
He felt the wet, rhythmic pulse of her life trying to escape between his fingers.
It was hot—scaldingly hot—and it felt like he was trying to plug a volcano with a handful of mud.
"Stay!" he roared, his face just inches from hers.
"You don't get to go! You hear me? I didn't give you permission!"
The blood jetted around his wrist, coating his arm to the elbow.
He was slippery, drenched in her essence.
His own wounds, the ones on his palms from the [Bone Blade]'s retreat, began to burn.
The salt in her blood hit his raw nerves, and a searing, white-hot agony shot up his arm, but he didn't pull back.
He pressed harder. He felt the jagged edge of her broken rib biting into his palm.
Sera's eyes were wide, dilated until they were almost entirely black.
She stared up at him, her body convulsing under the pressure.
She saw the madness in his eyes—not a hero's light, but a survivor's darkness.
The pain was a physical wall, but Kael was a hammer.
His hand began to glow.
At first, he thought it was the fungus above. But then he realized the light was coming from under his palm.
The blood wasn't just pooling anymore; it was reacting.
A deep, bruised violet light began to seep out from between his fingers, mixing with the crimson of her blood.
The system interface didn't just appear; it shattered into his vision, glowing with a violent intensity.
[UNEXPECTED ACTION DETECTED: VOLUNTARY SACRIFICE / PROTECTION PROTOCOL.]
[ANALYZING INTENT... EMOTIONAL TURBULENCE: CRITICAL.]
[BOND OF RECOGNITION: STAGE 1 – INITIATED.]
[ANALYZING SYNC RATE... 10%... 25%...]
The heat in Kael's arm escalated until he felt like his marrow was boiling.
He wasn't just holding her; he felt a literal bridge forming.
His own energy—the meager, flickering spark of life he had left—was being sucked through his hand like a siphon.
Sera let out a muffled, strangled cry.
Her hand, which had been feebly trying to push him away, suddenly clamped onto his forearm with a strength born of pure reflex.
Her fingernails dug into his skin, drawing more blood, further sealing the contact.
The violet light flared, blindingly bright, illuminating the dusty cache like a miniature sun.
[SYNC RATE: 40%... 55%... 70%!]
[TOTAL RECOGNITION ACHIEVED.]
[NEW STATUS UNLOCKED: BLOOD-BOND – STAGE 2.]
[WARNING: HOST VITALITY CRITICAL. PROCEED?]
Kael didn't even look at the "No" option.
He shoved his soul into the "Yes."
The room went silent, the only sound being the frantic, wet slapping of blood and the low hum of the system.
Sera's eyes locked onto Kael's, and for a fleeting second, the subtext of their survival vanished.
There was no knight, no scavenger, no Rank D or Rank F.
There was only the weight of the debt he was forcing her to carry—a debt of life that neither of them could ever pay back.
Kael felt his vision start to go black at the edges.
His heart skipped a beat, then another. He was fading, but beneath his hand, the wound was closing.
He could feel the skin knitting together, the flesh fusing with a supernatural speed that defied every law of nature he knew.
The blood grew tacky, then hot—boiling hot—and a faint smell of ozone and burnt sugar filled the air.
As the light finally began to dim, Kael felt the last of his strength evaporate.
His grip loosened, and he slumped forward, his forehead landing on her shoulder, his face buried in the wet mess of her blood.
He was empty. A hollow shell washed up on a beach.
Sera lay there, gasping, her chest rising and falling in a steady, albeit weak, rhythm.
She looked at the boy collapsed on top of her—the boy who had just torn a hole in reality to keep her from closing her eyes.
Her expression was unreadable: a mess of gratitude, terror, and a sudden, crushing realization of what had just happened.
They weren't just two survivors anymore. They were two ends of a bridge.
"You... you really are an idiot," she whispered, her voice trembling with an emotion she clearly didn't want to name.
She reached up, her fingers tentatively touching the back of his neck.
Kael didn't answer. He was too busy trying to keep his soul from leaking out of his ears.
But the silence didn't last.
From the narrow fissure leading out to the tunnels, a soft sound echoed: the deliberate tap of leather shoes on stone.
Tap. Tap. Tap.
Kael's eyes snapped open, even as his body refused to move.
Through the haze of his exhaustion, he saw a figure step into the dim light—a man, tall and lean, holding a silver-hilted rapier that hummed with a familiar, aristocratic mana.
"Well, well." The man's voice was a smooth, cold velvet.
"I thought I smelled something rotten. To think, the fallen Cavalier ended up in a hole with a piece of trash."
Sera stiffened beneath Kael.
"Vane..."
The man stepped into the light, a mocking smile playing on his lips as he looked at the blood-soaked scene.
His Guild badge glinted on his chest.
"The Marquis is quite impatient, Sera. He doesn't like losing his favorite toys. And as for you, boy..."
Vane raised his blade, the tip pointing directly at Kael's throat.
"I think you've lived quite long enough for a dead man."
Then, the only light in the room—the bioluminescent fungus—flickered and died, plunging them into absolute darkness.
