Chapter 17: Heaven's Wheel and Black Wings
The air crackled with a new kind of tension. The dismissal of the Flame Empress Armor wasn't a surrender; it was an escalation. The dozens of spectral blades orbiting Erza in the Heaven's Wheel Armor hummed with a sound like ringing crystal, each one a promise of pinpoint, overwhelming force.
Natsu's grin tightened, his controlled flames flaring in response. He'd forced a change. That was a victory in itself. But the Heaven's Wheel wasn't about defense or countering an element. It was about absolute, indiscriminate offense. Test phase three, he thought, magical evasion and area denial.
"Let us continue," Erza declared, her voice echoing with an otherworldly resonance. She didn't gesture. The swords simply moved.
They came not in a wave, but in a coordinated storm, a dozen streaking down from above, another dozen shooting in from the sides, the rest curving in complex arcs to box him in. It was a three-dimensional grid of death, leaving no obvious path of escape.
The old Natsu would have roared and tried to blast through. Toshiro-Natsu saw vectors and probability. He didn't have the speed to outrun them all. He needed to control the space.
He dropped to one knee, slamming both palms into the earth. "Fire Dragon's..." he began, but the incantation was a formality now. Instead of a forward blast, he channeled the power outwards in a desperate, expanding ring. "Inferno!"
A wall of fire, ten feet high, erupted from the ground in a perfect circle around him. It wasn't the delicate control of the fireball; this was raw, hungry power, shaped with a specific purpose. The leading spectral swords plunged into the flames. Some were vaporized instantly into puffs of light. Others, their magical momentum too great, shot through, but their trajectories were warped by the heat and turbulence, sailing harmlessly over his head or stabbing into the ground at wild angles.
The crowd roared. He'd blocked the first salvo.
But the wall of fire was a colossal drain. He could feel the magical energy in his gut dip sharply. And Erza had dozens more swords. As the inferno began to flicker, the second wave was already forming in the air.
He couldn't maintain this. He needed to move, to break the pattern. He let the wall die and exploded into motion, not away from the swords, but on a tangential, unpredictable path. He weaved, flames jetting from his feet to alter his direction in mid-stride, becoming a zig-zagging blur of pink hair and orange fire. A sword grazed his arm, leaving a searing line of pain. Another tore through the fabric of his scarf. He was faster than the original Natsu, his movements less wasteful, but he was still dancing in a hailstorm of blades.
He saw an opening, a momentary gap in the formations as Erza recalled swords for a new volley. He planted his feet, drew a breath that superheated the air around him, and unleashed a true, roaring cone of flame, Fire Dragon's Roar. It wasn't aimed at Erza, but at the dense cluster of reforming blades between them. The apocalyptic stream of fire engulfed them, melting the magical constructs into nothingness and carving a temporary, scorched corridor through the battlefield.
He charged down the corridor. This was his chance. Close the distance. Make it a brawl again, where her armor was less of an advantage.
Erza watched him come. As he crossed the halfway point, the remaining spectral swords didn't attack. They shot downwards, not at him, but into the earth in a wide circle around her, hilts quivering. A barrier? A trap?
He was ten feet away, fist cocked and blazing, when Erza raised a single hand.
The swords embedded in the ground detonated.
Not with fire, but with concussive bursts of pure magical energy. The ground heaved. The air became a solid wall of force. Natsu was caught in the overlapping blasts, his charge turned into a violent, uncontrolled tumble. He hit the ground hard, ears ringing, vision swimming. The Heaven's Wheel Armor hadn't just been for direct attacks; it was for area control and disruption.
He struggled to push himself up, his body screaming in protest. Through the dust and shimmering after-images, he saw Erza standing calmly. The last of the spectral light faded from around her. The Heaven's Wheel Armor was gone.
She's switching again. Now. I have to move now. He forced his limbs to cooperate, scrambling to find his footing. She wouldn't give him a straightforward power armor again. It would be something fast. Something to end it.
He predicted the Purgatory Armor, resistant to his flames. He braced for the Adamantine Armor, to overpower him with sheer defense. He gathered his remaining magic, ready to concentrate it into a single, desperate piercing attack.
The light around Erza shimmered, not gold or silver, but into deep, absorbing shadows.
A suit of armor as dark as a moonless night enveloped her. It was sleek, form-fitting, and utterly silent. Two great, blade-like wings of pure shadow unfolded from its back with a sound like a drawn dagger, the Black Wing Armor.
Natsu's mind, racing through catalogs of her known sets, went blank. A cold spike of dread pierced his battle-focus.
The Black Wing Armor didn't stride. It flowed. One moment Erza was twenty yards away, the next a shadow passed over him. He threw a wild, flaming punch at the blur. It hit nothing.
A voice, soft as a razor's edge, spoke from directly behind his left ear. "Your control is impressive, Natsu."
Before he could spin, an armored elbow connected with his kidney with surgical precision. The pain was breathtaking, a cold fire that locked his muscles. He stumbled forward.
"You read my patterns from the Flame Empress," the voice came again, now from his right. He lashed out with a jet of fire. It illuminated empty air. "But I have more than one pattern."
A kick, impossibly fast, swept his legs out from under him. He hit the ground on his back. He looked up, and there she was, hovering just above him, the black wings blotting out the sun. Her expression was unreadable behind the dark, avian helm.
He tried to summon a Roar, a last defiant blast. He opened his mouth, and a black, armored boot pressed down gently on his throat, not crushing, but silencing. The threat was absolute.
"The fight is over," Erza said, her voice final. "You pushed me to my third armor. That is a victory few can claim."
He wanted to protest, to struggle. But the precision of the beatdown, the total dominance of the Black Wing's speed, had left him with nothing. The magical exhaustion from the Inferno wall and the Roar, combined with the brutal, efficient physical strikes, left him broken on the ground.
He saw her dark gauntlet pull back, fingers forming a perfect, focused fist. It was the same move from the first time, but now refined by the dark armor's enhancement. It came down like a meteor.
He had just enough time for one last, coherent thought. 'I got her to use three armors. I made her get serious.'
Then, the world dissolved into a single, concussive impact of pure, starless black.
***
The silence in the clearing was absolute, broken only by the settling dust.
The crowd stared, stunned not just by Erza's display of overwhelming power, but by the unfamiliar, terrifying armor she'd worn at the end. Even the older guild members looked uneasy.
Lucy's hands were clamped over her mouth. Happy had buried his face in her hair, his tiny body trembling.
Erza stood over Natsu's unconscious form. The Black Wing Armor dissolved into motes of shadow, revealing her in her simple clothes once more. She knelt, checking his pulse with a professional detachment, then nodded once, satisfied.
She looked up at the silent, watching guild. Her gaze was fierce, proud, and utterly serious.
"Remember this," she said, her voice carrying to every ear. "This is what happens when you challenge someone who has truly dedicated themselves to their strength. Natsu fought well. He fought with a mind I have not seen in him before. But dedication… is everything."
She straightened, turning to walk back towards the town. The crowd parted for her like a sea before a battleship.
Behind her, on the scorched and torn earth, Natsu lay unconscious, blood trickling from a cut on his temple, his body a map of bruises and burns. He had been pummeled, outmaneuvered, and finally, decisively knocked out.
But in the guild's whispered conversations as they slowly began to move, the story wasn't just about Erza's victory. It was about the fire mage who had seen through the Flame Empress, who had made a wall of fire, and who had forced the Titania to unveil a power none of them had ever seen before.
He had lost the fight. But on the long, painful walk back to consciousness, he would know he had gained something invaluable: a true, terrifying benchmark for the power he would need to survive the future.
