Acnologia's arrival was naturally seen not only by Erza and Kyoka.
Mirajane, Wendy, and the other Nine Demon Gates' members who were also fighting saw it too.
"Acnologia? Why is Acnologia here?"
Wendy put some distance between herself and Tempester of the Nine Demon Gates. Looking at the pitch-black dragon in the sky, her face turned pale.
For Fairy Tail, Acnologia wasn't an ordinary dragon.
He was a nightmare.
Seven years ago, almost everyone in Fairy Tail nearly died at Acnologia's hands.
Although over the past seven years, Wendy, Mirajane, Erza, and the others, along with Kenichi, had also defeated the Five Dragon Gods on the continent of Guiltina, now, seeing the return of the Black Dragon from back then felt like a nightmare descending upon Wendy, Mirajane and Erza.
At the same time, Mirajane, who had transformed into her demon form, looked at the approaching Acnologia, her eyes flickering.
"Roar-"
Just as everyone was watching Acnologia, the steel dragon over there suddenly let out a roar towards the sky.
The steel dragon came from 400 years ago.
Back then, there were no Dragon Slayers.
No Acnologia.
No Dragon King.
So the steel dragon didn't recognize Acnologia.
But upon seeing Acnologia, the steel dragon sensed a dangerous aura from him.
Then, as if protecting its own territory, the steel dragon vigorously flapped its wings and its massive body charged directly towards Acnologia.
Acnologia's hatred for dragons had reached a terrifying level.
Now, seeing the steel dragon flying towards him, the killing intent in his pitch-black eyes was intense.
In the next second, Acnologia and the steel dragon, two colossal beings, collided directly in the sky.
At that moment, a terrifyingly loud noise echoed through the air.
A violent wave of air also spread out in all directions, centered on Acnologia and the steel dragon.
Mirajane, Wendy, Seilah, and others on the ground nearby were like small boats in a vast sea under the impact of this terrifying air wave, at risk of being blown away at any moment.
"Hey, hey, this is getting way too big. A fight between dragons!"
Silver, forced back a step by the air wave, looked at Acnologia and the steel dragon colliding in the sky and spoke with lowered eyelids.
After the steel dragon and Acnologia crashed head-on, both dragons retreated a distance.
Soon, Acnologia and the steel dragon launched another attack.
But Acnologia's strength was above the steel dragon's.
In just an instant, the steel dragon's massive body fell towards the ground below like a meteor.
Boom-
The moment the steel dragon hit the ground, the earth shook and cracked.
A large amount of rock debris, along with the terrifying air wave, spread out in all directions.
After sending the steel dragon flying, Acnologia didn't let it go.
He intended to kill all the dragons in the world.
Now that he had encountered a real dragon, he naturally wouldn't let it escape.
Acnologia vigorously flapped his black wings, and his massive body, accompanied by the sound of tearing wind, charged towards the collapsed steel dragon with an overwhelming force.
However, just as Acnologia's huge body was about to crush the steel dragon, a mountain rose from the ground beside the steel dragon and directly slammed into Acnologia.
The mountain had considerable impact force.
But when it struck Acnologia, it only pushed his massive body back slightly before the entire mountain collapsed.
The one who created this mountain was none other than Kenichi.
Now that this steel dragon had been subdued by Kenichi, he naturally couldn't just watch Acnologia kill it.
Just as Acnologia adjusted his stance, preparing to attack the steel dragon again, a multi-colored pillar of magical power shot up into the sky from Kenichi.
Sensing this exceptionally terrifying magical power, Acnologia's figure abruptly halted, and he turned his head to look in Kenichi's direction.
Soon, under the watchful eyes of Acnologia, Mirajane, Wendy, and the others, Kenichi's body began to enlarge at a visible rate.
Quickly, Kenichi transformed from his human form into an exceptionally massive golden dragon.
"What, what is that?"
"A dragon?"
"How can a dragon be that big?"
Kyoka in the distance looked at the golden dragon coiled between heaven and earth, its entire body emitting a dazzling golden light, full of a sacred aura, and spoke with shock.
At the same time, Seilah also looked at the golden dragon with disbelief.
Perhaps Kyoka didn't know who that golden dragon was.
But Seilah had witnessed Kenichi transform from his human form into the golden dragon before her with her own eyes.
"How…?"
"How did he turn into a dragon?"
"What in the world is going on?"
Silver, who usually regarded life and death lightly and didn't care about anything, looked at the golden dragon, and a rare look of surprise appeared on his perpetually lazy face.
"Yare yare, there seem to be an awful lot of surprising things today."
While Kyoka, Seilah, and the other demons were shocked by the golden dragon, Acnologia's eyes were filled with nothing but killing intent.
"I am the Dragon King, Acnologia!"
"All dragons must die!"
After declaring this in a voice full of authority, Acnologia's massive body charged directly towards the location of the golden dragon.
"He spoke?"
Hearing Acnologia's voice, Wendy was very surprised.
After all, seven years ago, when Acnologia descended upon Tenrou Island, he didn't say a single word.
But how could Wendy know that Acnologia simply disdained speaking back then.
At that time, in Acnologia's eyes, the mages of Fairy Tail were mere ants.
Would the Dragon King speak to ants?
Obviously not.
But now, Acnologia felt an unprecedented threat from Kenichi.
That alone was enough to earn Acnologia's serious attention.
Therefore, he spoke.
It seemed like a declaration of his victory.
A declaration that he was the strongest dragon.
