## Chapter 15 – Humanity's Response
Rain fell in sheets, thick and cold, blanketing the battlefield in a gray veil. The scorched cityscape hissed under the sudden downpour, steam rising from charred rubble. Fires flickered and sputtered but did not die. Neither did the war.
Kai stood at the edge of a crumbling skyscraper, cloak soaked through, dark hair plastered to his forehead. The Titan Creator System interface floated before him in an arcane glow. It shimmered as commands pulsed through it, funneling his will into the monstrosities tearing through the city.
Beneath him, thousands of **Pure Titans** marched forward, heedless of rain or fire. Some stood as tall as apartment buildings, others the size of buses. Their hollow eyes and twisted faces were terrifying in their blankness—a mindless army tethered to Kai's will.
And yet, humanity would not fall so easily.
Across the city, under the battered ruins of an old government facility, a new command center buzzed to life. This was **Fort Genesis**, the last active Tier-1 defense hub in the country. Protected by layers of reinforced steel and anti-Titan artillery, it had been constructed after the fall of the Shiganshina Gate incident decades ago. No one believed it would ever need to be used again.
But now it had.
Inside, monitors blinked with red alerts. Dozens of military strategists barked orders into radios. Screens showed horrifying images of Titans rampaging through neighborhoods, leveling skyscrapers, and crushing tanks underfoot.
"Status report!" a gruff voice roared. General Emilia Voss strode into the center of the room, her uniform soaked with sweat and grime.
"General! We've lost Sector 4. Titans breached the perimeter. 200 civilian casualties. All attempts to slow them down have failed."
"How many Titans?" she asked.
"Unknown. The number keeps rising. We've never seen anything like this."
Emilia's jaw clenched. She had faced dozens of Titan threats in her decades of service, but never one of this scale. Not even the events of Paradis or Marley's war could compare.
"There's only one explanation," she muttered. "He's not summoning Titans one at a time anymore. He's mass-producing them."
Silence followed. Even the humming of the command room felt quieter.
"Launch **Protocol Leviathan**," she finally ordered. "I want every surviving War Mech brought online. And prep the Titan Binding Serum. If we can capture even one of his creations... maybe we can reverse-engineer whatever he's using."
"But General," a young tech officer spoke up, "Protocol Leviathan was banned after the Eren Yeager incident. The cost—"
"I don't care about cost anymore," Emilia snapped. "This isn't a war. It's extinction."

Back on the surface, Kai continued his onslaught, but a subtle shift in the air caught his attention.
A strange vibration trembled through the ground, not from his own Titans, but from something... new.
From the north, enormous mechanical suits emerged from underground bunkers—**Titan-class War Mechs**. Each one was a relic of the old wars: thirty meters tall, built from a hybrid of anti-Titan steel and bio-organic tech salvaged from fallen shifters.
Kai narrowed his eyes.
"Humanity still clings to its toys," he whispered.
The first War Mech lunged forward, launching from its rocket-lined legs. It tackled a Pure Titan to the ground and drove an energy blade through its skull in one motion. Sparks and gore exploded. Another Mech followed, firing plasma bursts that vaporized several Titans in one sweep.
Dozens more activated across the city.
Kai issued a new command. The Titan Creator System pulsed, responding to the challenge.
**"Batch Create: 10,000 Pure Titans. Priority: Fort Genesis. Sub-priority: Eliminate War Mechs."**
The ground cracked like an egg. The roar of new Titans drowned out the Mechs' cannons.
What followed was chaos on a scale unseen in human history.
War Mechs tore through the first wave, but the Titans kept coming. For every one destroyed, five more rose. Kai's creations surged like an unstoppable virus, overwhelming defensive lines, breaching bunkers, and crashing into the steel giants in apocalyptic clashes.
Meanwhile, inside Fort Genesis, alarms wailed.
"They're targeting us!" shouted a tech officer.
"They know we're here!" someone else screamed.
Emilia Voss gritted her teeth. "Then it's time to end the guessing game."
She approached a locked case in the command room. Inside it was a single vial of **Titan Binding Serum**, synthesized from remnants of Zeke Yeager's spinal fluid. It was a last-ditch project—an attempt to paralyze a Titan's regenerative ability.
"Prep a sniper with aerial deployment. Load the vial. We hit the closest Titan and test the result."

Back above, Kai watched the world descend into chaos, but he was calm. Even… cold.
He raised both arms. The Creator System shimmered, but this time, he didn't summon more Titans. No—he prepared something else.
A new interface formed before him:
> **TITAN TYPE: CUSTOM**
> **BASE: Founding Titan (Altered)**
> **SIZE: Colossal**
> **SPECIALTY: Telepathic Command + Terraforming + Anti-Mech Pulse**
> **NAME: Leviathan Alpha**
Kai exhaled. "Let's give them something they'll never forget."
He activated the command.
The sky tore open with a blinding light. From the clouds above, a new Titan descended—one like no other. Larger than anything ever seen. Towering at 120 meters, its flesh was laced with glowing red lines. Its skeletal face lacked eyes, but its mouth seemed to stretch into a mocking smile.
It landed like a meteor.
Every War Mech in a ten-block radius shut down instantly. Sparks flew. Gears stopped. Lights died.
Kai smiled for the first time in hours.
"This is just the beginning."
