Ren took a deep breath, his fingers swiftly typing on the keyboard embedded in his car. As he pressed the final key, a more complex mechanical hum filled the air.
『Mode: Combat Suit – Activating.』
Vrrrrr... Clank! Clank! Psssshhhhh—
Inside the vehicle, several panels slid open, revealing hidden layers of armor. Mechanical components moved automatically, releasing a thin mist of steam as the metal joints adjusted to fit Ren’s body.
Two mechanical arms extended from the interior, each carrying pieces of armor that looked far sleeker than the traditional plate armor of this world. The suit had a futuristic design, predominantly matte black with silver-blue accents running along certain sections.
As the system’s voice echoed, the armor panels began attaching to Ren’s body, starting from his legs. A lightweight first layer covered his shoes, followed by additional plating that adjusted to his form, encasing his legs and knees completely.
A triangular chest plate locked into place, automatically connecting to the primary power source— a mini Ark Reactor embedded at the center. As soon as the device activated, silver-blue lines pulsed across the armor, flowing like streams of energy.
Psssshhhh... Click! Click!
The arm guards were fitted with flexible plating, allowing for rapid movement without compromising protection. On his wrists, small mechanisms were installed—expandable components that could function as either mini projectile launchers or emergency shields.
Finally, the helmet slid into place, emerging from the back and sealing shut with precision. A transparent visor briefly appeared before shifting into a sleek, blue digital display, immediately syncing with the suit’s control system.
Inside the helmet, the HUD (Heads-Up Display) came to life, displaying temperature readings, energy status, and a map of the surrounding area. The simple AI that Ren had personally modified—built from a repurposed smartphone he brought from Earth—began activating the suit’s primary functions.
『Combat Suit—Operational.』
Ren clenched his fists, feeling the familiar weight of the armor he had spent weeks developing. Though this was only the first prototype and had never been tested in actual combat, he was confident this technology could be a game-changer in this world.
He glanced at his reflection on a metal panel inside the vehicle, taking in his appearance now fully clad in high-tech armor.
"Hah... I really do look like a tokusatsu hero now."
From a distance, a group of elf children peeked out from behind the trees, frozen in shock. Their eyes widened, and their mouths hung open at a sight beyond even their wildest fairy tales.
To them, this man was no ordinary human.
He was like a god of war from another world.
"Alright~... Time for some rescues."
Ren’s voice was casual, but there was a firm resolve behind it. He pressed a button on his wrist, and once again, the sound of mechanical activation filled the air.
『Thruster System—Engaging.』
From his back, two panels unfolded to the sides, revealing a pair of jet thrusters that began glowing with a bright blue light. Meanwhile, two small nozzles extended from his calves, releasing thin streams of fire as the system initiated its startup sequence.
『Initial thrust—stabilizing.』
The air around Ren swirled, dust and leaves scattering as the pressure from his jet propulsion system increased. The elf children, still standing nearby, could only watch in stunned silence.
"W-what is that!?" one of the elf kids shouted, eyes bulging at the sight of blue flames bursting from Ren’s armor.
"T-that metal thing is breathing fire!!" another child stammered, stepping back in fear.
Shua, still standing among them, clutched her ragged clothing tightly. Her eyes were wide—not just with fear, but with awe.
"He... can really fly?" she murmured unconsciously as Ren’s body slowly lifted off the ground.
Ren adjusted his posture, slightly bending his knees to stabilize himself. The system inside his helmet displayed stability indicators, confirming everything was working as planned.
"Alright, everything’s set..."
Then, in a mere fraction of a second—
Ren shot into the sky at high speed, leaving a blazing blue trail in his wake. The sudden burst of wind from his launch forced the elf children to shut their eyes and hold onto each other to keep from falling over.
From below, they could only watch as the black-armored figure soared into the night sky, like a meteor moving in reverse.
"H-he’s not human... he’s a god!!" one of the children shouted in a trembling voice.
Shua continued staring at the sky, her small hands slowly clenching into fists.
"Mother... he’s going to save you."
And with that, the hero had departed for the enemy stronghold.
At the Elven Kingdom’s fortress, the battle raged through the night. Elven warriors fought desperately to hold their ground, but their numbers were far too few against the seemingly endless waves of human soldiers.
Despite their superiority in magic, the overwhelming difference in numbers was suffocating. Worse yet, the enemy used despicable tactics—hiding behind their own civilians as human shields.
The elven mages, who could have unleashed devastating spells, were forced to hold back. They couldn’t risk harming innocent lives, and the enemy exploited that hesitation to press forward.
On the battlefield, filled with screams of agony and the clashing of steel, the captured elves could do nothing but watch in despair.
Some elven soldiers began losing hope, realizing there was no way to turn the tide of battle. They needed a miracle. But no such thing existed.
A massive explosion erupted behind the human forces.
Flames roared high, debris and shrapnel scattering in all directions. The soldiers nearest to the blast were sent flying, some landing with their bodies scorched.
From the billowing smoke, a lone figure emerged.
A black armor with glowing silver-blue lines illuminated the battlefield. His eyes gleamed through his high-tech helmet, while steam rose from his legs and back-mounted thrusters.
He stood tall, scanning the battlefield like an executioner descending upon the chaos.
For a moment, silence fell over the battlefield.
Both elves and humans were frozen, captivated by the sight of something beyond their understanding.
