As Luna stood before Leon, her voice was as cold as ice. “Die,” she commanded.

"Ice Style: Ice Mist!" Leon thought quickly, summoning a thick mist of frost that filled the room. He grabbed Hanako and Akira, leaping out of the building with them. As they descended, he conjured an icy slide beneath them, racing toward the ground.

“Akira! How long until you can teleport us out of here?” Leon shouted, his heart pounding.

“I need more time! My power’s still recharging!” Akira responded, his voice strained with urgency.

Leon’s mind raced, realizing he needed a plan. He knew exactly how to stall Luna—and possibly even kill her.

As they reached the ground, Luna was already there, standing in their path with chilling indifference.

“Why are you running? You know you’re going to die,” she said, her cold eyes fixed on Leon.

Without hesitation, Leon jumped away, turning back to face Luna. “Hanako! Akira! Go! I’ll catch up!” he yelled.

Hanako and Akira exchanged a glance before running off into the distance, trusting Leon's command.

Leon steeled himself and put his hands together. “System call: Activate Project Omniadapter!” he shouted. The entire area around them plunged into darkness, and for the first time, Luna’s calm expression faltered slightly.

From behind Leon, a massive portal opened up, and a giant hand emerged, its force sending Leon flying to the side. He crashed into the ground, but despite the pain, a smile crept onto his face.

Luna’s eyes narrowed as the full figure stepped through the portal. The creature was massive—eight feet tall with a glowing, white body that radiated an intense, otherworldly power. Four angelic wings spread wide from its back, and its head was a burning mass of white flames, with a single shadowy eye visible within the blaze.

“This... thing. We found it in space, roaming aimlessly before it crash-landed on Earth. Let’s see if you can survive it,” Leon said, struggling to his feet as he watched the creature rise to its full height. "Try not to die."

Luna glared at Leon, her face twisted with a mix of anger and confusion. She was about to unleash her fury on him, but before she could strike, Hanako and Akira appeared, teleporting Leon to safety in a flash of light.

The moment they disappeared, Omniadapter launched its attack. A massive fist swung toward Luna, the air vibrating with its sheer force. Luna raised her arm, blocking the blow with ease, her eyes narrowing as she grabbed hold of the creature’s arm and spun off it with fluid grace.

“Die,” she hissed, and with the flick of her fingers, a concentrated laser shot from her hand, slicing through Omniadapter’s chest. For a second, it seemed the blow had landed a fatal wound, but the creature’s body regenerated instantly, its chest sealing up as if nothing had happened.

A sword materialized in Omniadapter’s hand, and without warning, it struck Luna, sending her crashing into a nearby building. The structure crumbled, engulfing her in smoke and debris. But as the dust cleared, Luna emerged, walking out unscathed. Her expression was cold and calculated.

“That sword… it’s infused with flux energy causing harm to my soul as well. . How annoying,” she muttered to herself, her irritation mounting.

She extended her fingers again, and another laser shot forth, this timeless effective against Omniadapter’s reinforced body. The creature retaliated with a powerful strike to her side, sending Luna crashing through several more buildings. She regained her balance mid-flight, landing on the side of a crumbling structure like a cat, her gaze now filled with murderous intent.

Omniadapter’s body began to grow, expanding in size as it moved atop the buildings with surprising agility. Its massive fists crashed down toward the ground, but Luna was quick, dodging the impact and leaping onto its giant arm. She spun and delivered a fierce kick to its flaming head, but Omniadapter reacted swiftly, grabbing her by the clothes and hurling her through the air.

Luna quickly regained control, but before she could counter, Omniadapter charged again. This time, lasers shot from Luna’s fingers, slicing through one of its arms and a leg. But the creature’s body only expanded further, growing more monstrous by the second. With a deafening scream, Omniadapter sent a shockwave that blasted Luna through more buildings, shattering windows and walls as she flew.

She landed on a rooftop, just as Omniadapter flew toward her, sword in hand. It aimed to impale her, but Luna caught the blade with her arm, blocking the strike as they both plummeted through the building, tearing it apart floor by floor.

Punch after punch was thrown, the sheer force of each blow shaking the ground and reducing Hakodate to rubble. Buildings collapsed all around them as their battle continued with relentless intensity. Luna blocked every one of Omniadapter’s attacks with a single hand, her movements swift and precise.

As the final building began to crumble beneath their feet, Luna leaped into the air, hovering above the destruction, her eyes fixed on Omniadapter. The creature’s flaming head burned brightly against the backdrop of the devastation, but Luna was far from finished. Her expression turned cold and ruthless as she prepared for the next phase of the fight.

Omniadapter charged at Luna with blinding speed, but Luna, always a step ahead, dodged and delivered a swift kick, sending the hulking creature crashing into a nearby parking garage. In a split second, Omniadapter retaliated, hurling debris wildly. Luna stood her ground, cutting through the incoming barrage with precise lasers, each strike cleaving the debris mid-air. As she concentrated, a well-aimed laser shot from her fingers, slicing off a chunk of Omniadapter’s flaming head.

Luna observed the creature closely. “My first laser worked, then it adapted. I altered the beam, and it was effective again, but now it’s learning my moves faster. This thing analyzes combat in real-time,” she thought, her mind racing. Omniadapter’s head was hanging by a thread, but with a grotesque determination, it pressed its flaming skull back into place. A faint smile appeared within its fiery face.

“Getting cocky, huh?” Luna muttered.

The city was now a warzone, destruction stretching as far as the eye could see. Civilians who hadn’t evacuated were caught in the crossfire. As Luna traded blows with the relentless creature, she was thrown through several buildings, crashing into one filled with people. Omniadapter followed, its sword slashing through anyone in its path. It swung its blade at Luna, but she evaded, darting to the side and placing her hand against its torso.

A massive explosion erupted from her palm, but Omniadapter’s regeneration was too quick. “Same laser technique, but every shot is becoming less effective,” Luna thought. She watched in frustration as the creature healed itself instantly, attacking with renewed vigor. It swung its sword again, but Luna deflected the attack and countered with a powerful kick, sending Omniadapter rocketing into the air.

Without hesitation, Luna leaped after it, kicking the creature again as it plummeted into another skyscraper. But Omniadapter recovered, tearing through the building like paper. The two clashed, their battle tearing apart everything in their path. As Omniadapter swung its massive fists, one connected with Luna, smashing her into the side of a towering skyscraper. The building shuddered and began to collapse.

“Now you’ve done it!” Luna roared, her patience wearing thin.

She unleashed a barrage of lasers, slicing through the skyscraper with ease. But Omniadapter, undeterred, used the falling debris as a shield, blocking the onslaught. In an impressive feat of strength, the creature hurled the debris back at Luna. Luna stopped mid-air, evading the attack as the debris rained down on the crumbling city. She descended into the wreckage, watching as Omniadapter shifted its size, growing into a giant form. It ripped apart another building and hurled the rubble, smashing it into more structures. Despite the chaos, Luna stood unharmed on a platform, a cold smile creeping across her face.

As Omniadapter shrank back to its original size and charged again, Luna danced around its attacks, sending lasers in every direction. The lasers sliced through anything in their path, sending humans flying and debris crashing into the streets. But Luna only seemed to grow more excited, a wicked smile plastered across her face as she laughed maniacally.

“You see it, don’t you, Omniadapter? You can see my lasers changing shape!” she shouted, reveling in the chaos. Her Yeager ability allowed her to manipulate her lasers’ form, size, and lethality—over a quintillion combinations at her disposal. She sent another wave of lasers, effortlessly cutting through Omniadapter’s limbs, severing them with precision.

But the creature was relentless. Even as its body was torn apart, it hurled its sword at Luna with incredible speed. She deflected it with her hand, but in the blink of an eye, Omniadapter regenerated faster than ever. It appeared right in front of her, its head flaming with fury. Luna didn’t flinch. They crashed through another building, the force of their fight shaking the ground as they traded blows. Omniadapter threw the first punch, but Luna gracefully dodged, rolling out of the way. They burst outside, and Luna unleashed another barrage of lasers, tearing Omniadapter’s body to pieces. Blood sprayed everywhere, painting the battlefield in a gruesome scene.

Omniadapter, now just a head, flew toward Luna, regenerating its entire body from the head in an instant. It attacked once more, but Luna dodged effortlessly, both of them landing on the ground. The battle paused for a moment, the two warriors standing still, their eyes locked on each other as if time itself had stopped. Then, in perfect synchronization, they both moved at once, ready for the next round of destruction.

Luna moved her arm gracefully, her smile widening as she unleashed a barrage of lasers, sending Omniadapter flying backward. Without missing a beat, she fired another laser, but Omniadapter swiftly blocked it. Undeterred, she sent out another, only for it to be deflected once more. In a blur of movement, Luna appeared behind Omniadapter, launching thousands of laser combinations in quick succession. Each beam was a different variation, aimed at tearing through the creature’s defenses. Omniadapter responded by throwing heavy punches, but its body was being disintegrated, blood splattering everywhere. Despite the onslaught, the creature regenerated just as fast.

Luna closed in, attacking at point-blank range, her lasers slicing through the air. But Omniadapter blocked each strike with precision. The battle seemed to evolve into a deadly dance—Luna standing still, her hands sending out lasers, while Omniadapter countered with shadow-like movements, punching the lasers away as if they were tangible attacks.

Suddenly, Omniadapter launched an uppercut, but Luna, still smiling, blocked it effortlessly. She rolled over its arm, landing a powerful kick to its head. A second, more devastating kick followed, sending Omniadapter crashing into a nearby building. As it crawled out of the wreckage, the creature lifted the entire building and hurled it at Luna. She responded with a volley of lasers, reducing the structure to dust. Debris rained down on the streets, causing untold destruction and killing civilians in the process. Luna, taking in the chaos, bowed mockingly at the devastation.

Omniadapter, now larger than before, charged at her with even more ferocity. Luna dodged the massive swing, hovering mid-air, her eyes briefly glancing at the moon above. As Omniadapter slowly rose to meet her in the sky, she spoke with admiration, “I’ve figured out your ability, monster. You can adapt to anything you fight. You learned my fighting style from the very first punch. You’re truly incredible.”

Her tone shifted, a sinister edge creeping into her voice. “But that means I have to use this.”

Luna formed a hand symbol, preparing for her next move, the air around her growing heavy with power.

“Moonlight Palace,” Luna whispered, her eyes gleaming as the moon itself began to shift, morphing into a massive plasma laser. The once serene glow of the moon twisted into a towering beam of destruction. Luna’s palace had manipulated the very moon to become a weapon of unimaginable power, capable of wiping out galaxies. But she reigned in its range, focusing the devastation to destroy only half of Japan.

She unleashed the laser, and everything in its path was obliterated. Buildings crumbled into dust, landscapes disintegrated, and Omniadapter’s body was reduced to nothing. Civilians caught in the crossfire were vaporized in an instant.

Rex, Hanako, Akira, and the others barely escaped. Thanks to Hanako and Akira’s quick thinking, they teleported themselves and the group to safety, far away from the destruction.

As the devastating laser continued to burn through the landscape, something unexpected happened. In the midst of the blinding light and devastation, Omniadapter’s body began to regenerate. Its disintegrated form was reforming, step by step, as it slowly walked through the Moonlight Palace’s beam. Luna’s smile widened, both impressed and enraged.

“You’re still standing?” she said, her voice filled with cruel excitement. “Fine then, let’s see how you handle this.”

Luna summoned her next weapon: “Yeager ability—Amelia’s Arrow,” she thought, creating a flaming arrow of concentrated energy. She aimed it directly at Omniadapter and released it. The arrow blazed through the sky, a second blast of pure destruction. It struck Omniadapter with overwhelming force, and for a moment, it seemed like the creature was finally defeated, its body nearly destroyed once again.

But in a last-second escape, Omniadapter opened a portal and slipped away, vanishing from Earth before the blast could finish it off.

Luna stood amidst the destruction, her gaze fixed on the spot where Omniadapter had disappeared, her smile unwavering.

“Finally, the war on Japan begins,” Luna said with a chilling smile, her voice echoing through the ruins of the shattered landscape.

Without another word, she disappeared into the shadows, vanishing from Japan, leaving behind a scene of destruction and a looming sense of dread. The battle had only just begun.
