The third month of the regression arrived with a conceptual fever that threatened to dissolve Ren Hanshin’s very marrow. In the depths of the Okutama forest, where the iron wreckage of the Kashima Maru lay like the ribcage of a fallen titan, the air had grown thick with the scent of ozone and burnt starlight. The training had moved beyond the physical endurance of the mud and the sensory deprivation of the dark; it had entered the realm of reconstruction.

Ren lay strapped to a slab of volcanic basalt at the center of the shattered shrine. His chest was bared to the leaden sky, and his right shoulder, the jagged, cauterized stump left by the God of Light was a raw wound of flickering violet mana.

The Weaver stood over him, her form more terrifyingly physical than Ren had ever seen. She had discarded her many-layered silks, wearing only a sheer wrap of crimson fate-threads that clung to her lunar-pale skin. Her obsidian lace mask was gone, revealing eyes that were no longer just stars, but entire swirling galaxies of obsession and hunger.

"The starlight limb was a gift, Ren," she whispered, her voice a shivering harmonic that bypassed his ears and resonated directly in his soul. "And because it was a gift, the God of Light could take it back. Today, we forge something that belongs only to the Abyss. We graft the Obsidian Ash of your failures into the Crimson Silk of your fate."

She raised her hand, and from the surrounding forest, the shadows began to liquefy. They crawled toward the basalt slab like black vipers, carrying with them the pulverized remains of the salt pillars and the leaden dust of the Golden Sovereign’s realm.

"This will not be a healing, my king," the Weaver murmured, leaning down until her cold, starlight breath brushed his lips. "This will be a violation. I am going to stitch the void into your bones."

She began.

The first needle of fate-silk pierced his shoulder, and Ren’s world exploded into a kaleidoscope of white-hot agony.

"AGHH!!" Ren’s back arched off the basalt, his left leaden arm straining against the silk restraints until the stone beneath him cracked. He was feeling the graft. The Weaver was using her threads to lace the liquid obsidian ash directly into his nervous system.

The conceptual fever took hold.

Ren’s mind was cast into a vortex of echoes. He wasn’t in Okutama anymore. He was back in the Shinjuku fire, carrying a bag that was filled with his own severed limbs. He was in the Necropolis, the Silent Queen’s porcelain hand reaching for his throat. He saw Jubei, his old master, standing in a field of burning pines, pointing a wooden sword at his heart.

"You’re dropping the bag, Ren," Jubei’s ghost whispered. "A porter who drops the bag is just a man with a heavy back."

"I... am... not... dropping it!" Ren roared in his mind, his soul thrashing against the Weaver’s intrusion.

In the physical world, the Weaver climbed onto the basalt slab, straddling Ren’s chest to pin him down. Her many spiritual limbs manifested, hundreds of starlight needles dancing in her hands as she worked with a feverish, manic intensity. She was stitching him, weaving him, molding him into her perfect needle.

"Stay with me, Ren!" she commanded, her face inches from his, her eyes flaring with a jealous, celestial heat. "Don’t look at the ghosts! Look at the shadow! The shadow is the only thing that doesn’t lie!"

As the obsidian ash fused with his bone, Ren’s body began to reject the divinity. His 40.0% synchronization spiked and plummeted, his mana-core vibrating with the force of a tectonic shift. To survive the graft, he had to embrace the dirt more than ever before. He had to use his human stubbornness to anchor the abyssal power.

The manifestations of his court — the Silent Queen and the Auditor’s Handmaidens circled the slab. They sang a low, haunting dirge that acted as a conceptual anesthetic, their translucent hands stroking Ren’s brow and legs, trying to keep his human heart from stopping. But their touch only fueled the Weaver’s possessiveness.

She pushed the Silent Queen’s reflection aside with a snarl of crimson mana. "He is mine! His pain is mine! His rebirth is mine!"

She leaned down, pressing her mouth to the raw, obsidian wound of his new arm. She was inhaling the rejection. She took the excess mana into herself, her own body glowing with a bruised, violet radiance as she shared the burden of his evolution.

Ren’s obsidian arm began to take shape.

It wasn’t porcelain. It wasn’t skin. It was a limb of matte-black glass, etched with crimson veins that pulsed with a dark, gravitational light. It didn’t reflect the grey sky of Okutama; it seemed to pull the light into itself, a localized void that made the air around it feel heavy.

The fever broke in a final, violent surge of mana that shattered the basalt slab into dust.

Ren lay in the mud of the shrine, gasping for air. His new arm felt like a cold, heavy anchor. He moved his fingers, the black glass clicked with a metallic sound. He could feel the friction of the world through the obsidian. He could feel the threads of the trees, the heartbeat of Haru in the distance, and the mocking glare of the sun above.

The Weaver lay draped across him, her crimson silks soaked in his silver blood, her breathing as ragged as his. Her mask was gone, and her face was a masterpiece of divine exhaustion and obsession. She looked at the new arm she had crafted, her silver nails tracing the crimson veins.

"It is beautiful, my king," she whispered, her voice a low, intimate purr. "It is a limb that can reach into the sun and pull out the heart. It is a limb that belongs only to the Weaver and her Porter."

She leaned up, her lips meeting him in a kiss that tasted of iron, ash, and the absolute dark. It was a seal on the contract of two monsters bound by the same shadow. Ren didn’t push her away. He gripped her waist with his new obsidian hand, the cold glass digging into her silk. The friction between them was no longer just power; it was a hungry, desperate heat that ignored the rain and the mud.

"I can feel the sun, Weaver," Ren rasped, his eyes twin pits of obsidian void. "I can feel the knot in its throat."

"Then we are ready for the fourth month," she murmured, her face buried in the crook of his neck. "The month where the Porter becomes the Master."

The second half of the month was dedicated to Synchronization Training. The Weaver led Ren to the edge of a massive, flooded quarry at the base of the mountains. The water was a dark, stagnant green, reflecting the bruised sky.

"The obsidian arm is a hunger, Ren," Weaver explained, standing on the surface of the water as if it were solid glass. "If you do not control its appetite, it will eat your own mana until there is nothing left of you but a shadow. You must learn to pulse the void."

She manifested three Echoes of Solis, crystalline warriors made of captured sunlight. They stood on the banks of the quarry, their spears aimed at Ren.

"Kill them," she commanded. "But do not use the scythe. Use the Graft."

Ren stepped onto the water. He didn’t use mana to stay afloat; he used the obsidian arm to anchor his weight to the liquid. He lunged at the first Echo.

The crystalline warrior fired a beam of holy light. Usually, Ren would have to block or dodge. But this time, he raised the obsidian hand. The light didn’t hit him. It was consumed.

The black glass of his hand glowed with a faint, trapped violet light for a microsecond before the crimson veins pulsed, neutralizing the energy. Ren reached out and grabbed the Echo’s head. He didn’t squeeze. He deducted.

He channeled the bankruptcy of his soul through the obsidian limb, and the crystalline warrior didn’t shatter, it devalued. The light was sucked out of its body, leaving behind a pile of worthless, grey sand that sank into the quarry.

Ren moved through the remaining Echoes with a brutal, mechanical efficiency. He was a Porter clearing a path. Every strike with the obsidian arm left a Void-Trail in the air, a dark violet distortion that refused to fade.

By the end of the month, Ren’s synchronization had reached the stabilized plateau of 50%. The porcelain cracks on his chest had been filled with obsidian ash, and his starlight hair was beginning to return as a deep, midnight indigo that drank the light.

He stood at the center of the quarry, the water beneath his boots turning to ice from the cold mana, he radiated. The Weaver approached him, her many spiritual limbs weaving a cloak of obsidian silk around his shoulders.

"You look like a Sovereign of the Abyss, Ren," she murmured, her arms wrapping around his waist from behind. "The God of Light is watching from his forge. He sees the shadow growing in the mud. He is afraid."

Ren looked at his obsidian hand. He could feel Haru’s sapphire light in the distance. She was safe, but she was far away, separated from him by the wall of silk and ash he had built to protect her.

"Let him be afraid," Ren said, his voice a singular, heavy command. "The Porter is almost done with the training. And the delivery I’m bringing to Solis... is the End."

The Weaver leaned her head against his back, her eyes closed in absolute delight. "The fourth month is next, my king. The Shinen-ryu Reversion. We will go back to the beginning, so you can destroy the future."

Ren gripped the rusted handle of the Severance of Destiny, which lay in the mud at the quarry’s edge. The blade didn’t shine, but as he touched it, the rust began to flake away, revealing a dark, matte-black metal beneath.

The third month was over. The Obsidian Graft was complete. And in the silence of Okutama, the Executioner was no longer a slave to the Weaver’s thread. He was the one who held the needle.
