Chapter Sixteen: Enter the Graveyard

Zero stood on the parapet overlooking the dungeon in the distance.

Even from here he could feel it — a deep, persistent animosity radiating from the massive structure. The aura was colder and heavier than anything he had sensed from the Spiral Dungeon in Tokyo. It felt old. Hungry. Wrong.

Okunoin had once been the largest and most sacred cemetery in Japan, a place where the dead were meant to rest in peace at the foot of Mount Kōya. When the dungeons overtook the world’s landmarks, it had become something else entirely. The Dungeon Society now ranked it as the largest and most dangerous dungeon in the country.

Akane Azuma stepped up beside him, arms crossed as she stared at the distant mass of twisted stone and dark energy.

“Not really a marvel as it used to be before the dungeons took over,” she said quietly. “It was a sacred place once. Where our dead could rest in peace. Now? Undead crawl from every corner of it. Dreadwalkers, Night Wights, and several dozen other classifications of the dead roam those halls looking for something to devour.”

Zero kept his eyes on the dungeon.

“How deep does it go?”

“Deeper than we’ve been able to map,” Akane replied. “The upper floors are bad enough. Past the middle layers, communication starts failing. Teams that push too far either don’t come back… or come back changed.”

She glanced sideways at him.

“That’s why you’re here. The Tyrants can handle most of what the upper and mid floors throw at them. But the deeper levels have been getting worse. The aura has been expanding for weeks. Something down there is stirring.”

Zero rested a hand on the hilt of his sword.

“Good.”

Akane raised an eyebrow.

“Most people would be concerned.”

“I’m not most people.”

A cold wind swept across the parapet, carrying with it the faint, distant stench of old death and corrupted mana. Far below, the dark silhouette of Okunoin seemed to pulse once, almost as if it had noticed them watching.

Zero’s expression didn’t change.

“At dawn the Tyrants will be dispatched to Okunoin,” Akane said. “While they dismantle the upper floors, I want you to investigate the lower levels. If the Sidhe are indeed causing this, eliminate them without restraint.”

She glanced at the dark mass of the dungeon in the distance, then back at Zero.

“I’d suggest you head to the quartermaster here and get some new gear fabricated. Central has their smiths working overtime, but ours is more… specialized. Think carefully about what you want most.”

Zero was quiet for a moment. The dream from the previous night still lingered — the memory of himself standing on a battlefield in armor so heavy the earth cracked beneath his feet, yet moving with the speed of the wind. Perhaps that had never been about some mythical material. Perhaps it had simply been his own strength.

“Heavy armor,” he said at last, touching his chin. “The heaviest you have.”

Akane nodded without surprise.

“Reinforced with Magicyte circuits, and a few other things. Don’t worry — once our quartermaster starts on your gear, he won’t stop halfway. Time moves differently here. The proximity to so many temples and sacred grounds gives us the window we need to work properly.”

She turned and began walking away, then paused.

“Get what you need. At dawn, you go in.”

Zero watched her leave, then headed toward the quartermaster’s forge.

His current sword would no longer be enough. Whatever waited in the lower floors of Okunoin would demand something sharper… and far stronger.

The quartermaster’s forge sat in a reinforced wing of Wakayama HQ, partially built into the mountainside. The air inside was thick with the scent of heated metal, molten Magicyte, and ozone. Sparks occasionally flared from the deeper workshops as automated hammers and rune-etched tools worked in steady rhythm.

A broad-shouldered man with a heavy apron and glowing prosthetic arm looked up as Zero entered. His eyes narrowed slightly when he recognized the silver-haired Class 5.

“You’re the one Commander Azuma sent,” the man said. His voice was rough, like gravel. “Name’s Daisuke. What do you need?”

Zero stepped up to the counter and rested a hand on the hilt of his current sword.

“Heavy armor. The heaviest you can make. Reinforced with Magicyte circuits. Something that won’t slow me down.”

Daisuke raised an eyebrow.

“Most people who ask for the heaviest end up regretting it. The weight alone can crush a normal Delver’s movement.”

“I’m not a normal Delver.”

The quartermaster studied him for a long second, then gave a short, approving grunt.

“Fair enough. We’ll use layered Magicyte-steel plating with internal reinforcement circuits. Flexible joints, impact dispersion runes, and a self-repair weave if we have the materials. It’ll be heavy as hell… but if you’re as strong as the reports say, you’ll move just fine.”

Zero nodded once, then unstrapped his current sword and placed it on the counter.

“This won’t be enough. I need something sharper. Stronger. Something that won’t break against Sidhe weapons or Angel-class entities.”

Daisuke picked up the blade, examined the edge, then set it aside.

“We can do better. There’s a batch of high-density Magicyte crystal we’ve been refining — unstable for most weapons, but if the core is properly bound, it can cut through things that normal steel can’t touch. I’ll need a day to stabilize it.”

“Dawn is when we deploy.”

“Then you’ll get it by dawn,” Daisuke said flatly. “Commander Azuma already put a priority seal on your request. I’ll pull the night crew.”

Zero gave a short nod of thanks and turned to leave.

Behind him, the forge roared louder as Daisuke began issuing orders. Sparks flew. Metal rang.

By the time the sun rose over Wakayama, Zero would step into Okunoin wearing armor that could withstand the weight of a forgotten king’s past… and carrying a blade meant to cut through whatever the dungeon — or the Sidhe — threw at him.

Dawn arrived slowly over Wakayama.

Zero stood in the courtyard wearing his newly fabricated gear. The armor was as black as night, heavy plates reinforced with dense Magicyte circuits that pulsed with a deep maroon glow. A long dark cape with matching red-edged patterns hung from his shoulders, shifting slightly in the cold morning wind. In his hand rested the new sword — longer, heavier, and far sharper than the previous one, its core faintly glowing with the same dark red energy.

The Tyrants were already assembled.

Raiden Kurogane gave Zero a once-over and nodded in approval.

“Looks heavier than standard issue. You can actually move in that?”

Zero rolled his shoulders once. The armor shifted with him smoothly despite its weight.

“It’ll do.”

Yumi Shinohara leaned against the side of the vehicle, arms crossed, twin short swords already strapped to her hips.

“Most Class 5s I’ve heard about either go insane or get locked back up. You’re surprisingly quiet.”

Kai Hayashi grinned as he adjusted the floating Magicyte orbs around his staff.

“Quiet is fine. As long as he doesn’t slow us down when things get messy. The upper floors of Okunoin are already crawling more than usual.”

Sora Amemiya gave Zero a calm, polite nod.

“If your Magicyte circuits start destabilizing under the dungeon’s pressure, tell me immediately. I’ll stabilize them.”

Raiden jerked his head toward the large armored truck waiting nearby — a mobile command unit, necessary because Wakayama HQ lacked a permanent outpost this close to the dungeon.

“Load up. We’re rolling out.”

The team climbed into the vehicle. Zero took a seat near the back, the heavy armor making a low metallic sound as he settled in. The truck’s engine rumbled to life, and they began the short drive toward the outer perimeter of Okunoin.

Inside the cabin, the atmosphere was tense but professional.

Raiden glanced back at Zero from the front.

“Once we’re inside, the Tyrants will clear the upper floors and establish a temporary forward point. You’re going deeper alone. Commander Azuma’s orders. Don’t die before you find something useful.”

Zero rested the new sword across his knees, eyes half-lidded.

“I’ll try not to.”

Yumi smirked faintly.

“At least he’s not the type to talk too much.”

Kai laughed under his breath.

“Give it time. The dungeon has a way of making people talk… or scream.”

Outside the reinforced windows, the dark silhouette of Okunoin grew larger. The evil aura surrounding it pressed against the vehicle like a physical weight.

Zero closed his eyes for a moment, feeling the familiar pull of violence settle into his bones.

Whatever was waiting in the lower floors… he would meet it head-on.
