The dirt tasted like old iron and rot.
Ren pressed his face into the damp earth behind the oak tree. He kept his jaw locked entirely shut. His teeth ground against the bone of his own forearm. The skin there was already broken. Hot blood pooled in his mouth, threatening to choke him. He did not swallow. He did not move a single muscle.
The left side of his back was on fire.
It was not a metaphor. It was a literal, catastrophic biological failure. The System had forced his human biology to absorb fifty percent of a High-Class Devil's destruction magic. The flesh over his left shoulder blade was actively cooking. He could smell it. It was a sickening, sweet aroma of burning protein and scorched fabric that completely overpowered the scent of the nearby pine trees.
Thirty yards away, by the ruined fountain, Rias Gremory was finishing her ritual.
"Live for me, Issei Hyoudou."
The velvet voice floated across the freezing park. It was followed by a massive, blinding pulse of crimson light. The overwhelming demonic pressure in the air doubled for a fraction of a second. It pressed down on Ren's skull like a physical anvil.
Then, the pressure stabilized. The boy on the cobblestone took a deep, rattling breath. He was no longer human. The transaction was absolute.
Ren kept his eyes squeezed shut. The agony in his shoulder was spreading. It crawled up the back of his neck, turning the skin hot and tight. He needed to pant. He needed to scream. He forced his breathing to remain incredibly shallow. A single, ragged gasp would betray his position. Devils had heightened senses. They could hear a heartbeat.
"President."
Akeno Himejima's voice cut through the silence. It was sharp. The polite, aristocratic lilt was completely gone.
"I smell burning flesh. And fresh blood. It is coming from the tree line."
Ren's heart stopped.
The silence in the park became absolute. The rhythmic dripping of the damaged fountain sounded like a ticking bomb. Ren pressed his body deeper into the mud. The cold earth offered no protection. He was a crippled, bleeding human hiding in the dark. He had absolutely no leverage left. If Akeno walked behind this tree, the execution would be immediate.
"The Fallen Angel," Rias replied calmly. Her voice did not move closer. "My attack grazed her wing before she ascended. The wind is carrying the ash back down. And the boy lost a significant amount of blood."
"It smells different," Akeno noted. The air crackled faintly with residual yellow lightning. She was suspicious. She was the Queen. It was her job to find the anomalies.
"Leave it," Rias commanded. The tone allowed no argument. "We have the Longinus. We need to move the new Pawn to a secure location before the Fallen Angels realize their scout has failed. The territory is unstable tonight."
Ren waited. He counted his own erratic heartbeats. One. Two. Three.
A heavy, magical distortion popped the air in the center of the park. It sounded like a vacuum seal breaking.
Ren slowly opened his eyes. He forced his heavy, trembling neck to turn. He looked past the rough bark of the oak tree.
The fountain was empty. The dark bloodstain on the cobblestone was the only proof that a boy had just died there. Rias, Akeno, and Issei were gone.
Ren let out the breath he was holding.
It came out as a pathetic, wet sob. He immediately clamped his bloody hand over his mouth. He squeezed his eyes shut as a violent tremor wrecked his entire body. The adrenaline of the immediate threat was fading. The pure, unfiltered reality of his physical trauma rushed in to fill the void.
His left arm was completely dead. It hung uselessly at his side. The nerve endings in his shoulder were screaming.
He had to move. The park was not safe. The scent of his own burned blood was a beacon for any stray supernatural entity wandering through Kuoh.
He pressed his right hand flat against the mud. He pushed upward.
His brain misfired violently.
The dark park vanished. The bright, sterile fluorescent lights of his old corporate office blinded him. He was standing by the water cooler. A junior associate was talking to him. The associate was holding a cup of scalding hot coffee. The cup slipped. The boiling liquid splashed across Ren's shoulder.
"I'm sorry, Mr. Kuruma," the associate stammered.
Ren blinked. The office shattered.
He was back in the mud. He was on his hands and knees. He was vomiting a thin, acidic string of bile onto the roots of the oak tree.
Hypoxia and clinical shock. His brain was failing to process the magical trauma. It was desperately searching his human memories for a comparable experience. A spilled cup of coffee. It was a pathetic, laughable comparison to a demonic destruction spell.
He wiped his mouth with the back of his right hand. He forced himself to stand.
The world tilted dangerously to the right. He leaned his weight heavily against the tree trunk. He looked down at his clothes. His Kuoh Academy uniform jacket was soaked in mud and his own blood. The fabric on the left side of his back was completely gone, burned away to expose the ruined skin beneath.
He took a step forward. His left leg dragged clumsily in the dirt.
The journey back to his apartment took exactly forty-two minutes. It was a march through a living nightmare.
The streets of Kuoh were quiet. The cold wind bit mercilessly into his exposed, blistered flesh. He navigated through the dark alleys, actively avoiding the yellow glow of the streetlamps. Every step sent a fresh, sickening jolt of agony up his spine. He had to consciously remind his lungs to expand. He had to negotiate with gravity just to stay upright.
He reached his apartment building. It was a cheap, two-story complex on the edge of the residential district.
He dragged himself up the concrete stairs to the second floor. He leaned against his front door. His breathing was loud, ragged, and wet. He reached into his right pocket with his functioning hand. He pulled out his keys.
His fingers refused to close properly.
The metal keys slipped from his trembling grip. They hit the concrete walkway with a sharp, mocking clatter.
Ren stared down at the keys. A profound, crushing wave of despair settled heavily in his chest. He was the Architect of Absolute Contracts. He had manipulated a Devil King and bound a Fallen Angel. And now, he was going to bleed to death on his own welcome mat because his human fingers could not hold a piece of metal.
He sank slowly to his knees. He picked up the keys with both hands, pressing his palms together to force the metal into the lock. He turned it. The deadbolt clicked.
He pushed the door open and collapsed into the dark hallway of his apartment.
He kicked the door shut behind him. He did not bother to turn on the main lights. The pale moonlight filtering through the kitchen window provided enough illumination.
He crawled across the cheap linoleum floor. He reached the small bathroom.
He pulled himself up using the edge of the porcelain sink. He reached out with a trembling right hand and flicked the light switch.
The harsh, artificial light buzzed to life.
Ren looked into the mirror above the sink.
The boy looking back at him was a ghost. His skin was the color of old chalk. His dark hair was plastered to his forehead with cold sweat and dirty rain. Dried blood coated his chin and his left forearm.
He slowly reached across his chest. He grabbed the collar of his ruined uniform jacket. He pulled it off. The fabric stuck to the burn on his back.
He ripped it free in one violent motion.
A sharp, breathless scream tore from his throat. His knees buckled, but he caught his weight on the sink. He gripped the porcelain until his knuckles turned pure white. He forced himself to stand up straight. He turned his back slightly to the mirror. He looked over his right shoulder at the reflection of his injury.
It was not a normal burn.
The flesh over his left shoulder blade was charred a deep, sickening black. The edges of the wound were blistered and raw. But the center of the burn was terrifying. The destruction magic had left a permanent signature. Jagged, glowing crimson veins radiated outward from the center of the charred flesh. They pulsed faintly, synchronized perfectly with his erratic heartbeat.
It looked like a demonic crest carved directly into his human meat.
The System had not just shared the trauma. It had physically altered his biology to contain the magical fallout. The toll was visible. It was permanent.
"System," Ren rasped. His voice sounded like grinding stones.
The heavy scent of burning parchment filled the small bathroom. It mixed sickeningly with the smell of his own cooked flesh. The golden text ignited in the mirror, overlaying his broken reflection.
[The Archive of Absolute Contracts]
[Host Vitality: Critical. Severe magical contamination detected.]

He stared at the words. He was stable. Raynare was stable. They had both survived the execution.
He reached out and turned on the cold water tap. He cupped the water in his right hand and splashed it over his face. He watched the pink, bloody water swirl down the drain.
He had won. He had secured his position in the city. Rias believed his lie. She had her prize. She would leave him alone.
He turned the tap off. The bathroom fell completely silent.
Then, the tether pulled.
It was not the frantic, erratic pulse of Raynare's fear. It was not the psychotic, manic high of her bloodlust. It was something entirely different. It was a slow, deliberate, heavy pull on the metaphysical chain anchored in his chest.
Ren froze. The cold water dripped slowly from his chin.
The absolute override he had used in the park was a massive violation. He had forced somatic control on her body. He had slammed a steel door on her mind. In doing so, he had opened his own mind completely. He had bridged the gap.
She had felt him.
The tether pulled again. It was stronger this time. It felt like a massive weight shifting at the other end of a dark tunnel.
The golden text in the mirror flickered violently. The letters distorted, breaking apart into meaningless symbols. The scent of parchment vanished completely. It was replaced by the smell of ozone and wet black feathers.
A voice echoed in the hollow space behind Ren's eyes. It was not an accidental broadcast of her internal thoughts. It was a direct, intentional transmission.
You.
The voice was pure, unadulterated venom. It dripped with a terrifying, cold fury that made Ren's blood run completely cold. It was the voice of a humiliated predator.
You are in my head.
Ren gripped the edges of the sink. He stared at his own terrified reflection. The parasitic contract was supposed to be a one-way mirror. He was supposed to hold the leash. He was supposed to be the master.
He had miscalculated. The shared trauma had broken the mirror.
I feel you breathing, human. The melodic voice whispered in the dark corners of his mind. I feel your pain. I feel your broken shoulder.
The invisible chain pulled taut in his chest. It stole the breath directly from his lungs.
I know exactly where you are.
The fluorescent light above the mirror gave a loud, sharp pop. The bulb shattered instantly, plunging the small bathroom into absolute, suffocating darkness.
