Natsu is a Fire Dragon Slayer, and he can devour fire, making fire-based magic ineffective against him.
Laxus is a Lightning Dragon Slayer, and he can devour lightning, making lightning-based magic ineffective against him.
…
Kenichi had previously conceived the idea of collecting all attribute Dragon Slayer Magic attributes. That way, he could devour all magic, and all magic would be ineffective against him.
So far, Kenichi had collected Fire, Iron, Lightning, and Poison Dragon Slayer Magic attributes.
As for Wendy's Sky Dragon Slayer Magic attribute, Kenichi could collect it anytime he wanted.
But after fighting Hades, Kenichi changed his mind.
Hades said: All magic originates from darkness.
In other words, whether it's Fire, Lightning, Iron, or any other attribute series, they are all branches of Dark Magic.
Kenichi thought that if he could find the Darkness Dragon Slayer Magic, he could devour all attribute magics and be immune to all types of magic.
When Acnologia appeared, Kenichi suddenly remembered that Acnologia himself was a Dragon Slayer, and he could devour all magic and was immune to all magic.
Although in the original story, Acnologia mentioned his attribute was 'None'.
But Kenichi speculated that Acnologia was actually a Darkness Dragon Slayer. (T/N: From what I found in the wiki, Acnologia's magic is Arcane Dragon Slayer Magic.)
If Acnologia were a Darkness Dragon Slayer, then by collecting Acnologia's Dragon Slayer Magic, Kenichi could, like Acnologia, be immune to all magical attacks and devour all magic.
Of course, whether Kenichi's speculation was correct required testing.
Even if Kenichi's guess was wrong, obtaining Acnologia's Dragon Slayer Magic attribute wouldn't be a loss.
"Although it will be troublesome, it's not without opportunity!"
Kenichi looked at the massive Acnologia before him and said seriously.
"Natsu, lend me Igneel!"
That's right, Kenichi wanted to manifest the Fire Dragon King, Igneel to fight Acnologia.
Of course, with Kenichi's current magical power, the manifested Igneel probably wouldn't even have one-tenth of his true strength.
But Kenichi didn't expect the manifested Igneel to defeat Acnologia.
He just needed to induce Acnologia to use his Dragon Slayer Magic.
Kenichi didn't hesitate and immediately used the [Historia of the Dead] on Natsu over there.
As the Historia of the Dead was activated, numerous memory images appeared in Kenichi's mind.
These memory images were all Natsu's memories.
Soon, Kenichi locked onto the memories related to Igneel.
Just like when he manifested Hades before, Kenichi used Natsu's memories of Igneel to outline everything about Igneel in his mind.
After the image of Igneel was fully imagined by Kenichi, he directly activated Rustyrose's [Arc of Embodiment].
Bzzzt-
As the Arc of Embodiment magic activated, a behemoth appeared in the sky above Kenichi.
It was a dragon.
A dragon entirely fiery red.
And this dragon was none other than the Fire Dragon King, Igneel.
"Another dragon appeared?"
"What in the world is...?"
Seeing the giant dragon appearing above Kenichi, the faces of Erza, Wendy, and the others all changed.
But Natsu shouted loudly: "Igneel! It's Igneel!"
"Natsu, sorry, but this isn't Igneel. It's created by my magic."
Kenichi said to Natsu, then flashed, as if teleporting, onto Igneel's back.
"Really? Kenichi can even create dragons?"
"Isn't that too exaggerated?"
Hearing Kenichi's words, Gray and the others all looked dumbfounded.
However, Kenichi didn't have time to explain much to everyone. After arriving on the manifested Igneel's back, he directly manipulated Igneel to fly into the sky.
"Will he follow?"
Kenichi looked at Acnologia and thought to himself.
If it were the real Igneel, Acnologia would definitely chase immediately.
But Kenichi knew Acnologia could 100% tell this Igneel wasn't the real one.
Yet Kenichi also underestimated Acnologia's desire to slay dragons.
Whether it was a real dragon or a manifested dragon, he wanted to destroy them all.
He even wanted to slay Kenichi, a Dragon Slayer himself.
"He's coming!"
Seeing Acnologia actually follow, Kenichi's mind stirred, but he wasn't happy.
After all, his opponent was Acnologia, so he couldn't afford to be careless.
And so, Acnologia continuously chased Kenichi and the manifested Igneel, heading away from Tenrou Island.
Seeing this scene, Erza, Mirajane, and the others were all deeply moved.
Because in their view, Kenichi was disregarding his own life and death for them, intentionally luring Acnologia away.
"Kenichi, please be safe!"
"Kenichi-nii!"
…
Kenichi naturally didn't know everyone's thoughts. At this moment, he was riding the manifested Igneel in a full-speed dash.
Finally, the continuously chasing Acnologia lost patience.
He opened his mouth wide and took a deep breath.
Bzzzt-
The next second, a pale blue magical beam containing an aura of destruction shot directly towards Kenichi and the manifested Igneel.
Fortunately, Igneel dodged quickly. The huge pale blue magical beam brushed past Kenichi's side and ultimately landed on the sea.
Bzzzt-
At that moment, an extremely dazzling light bloomed on the sea.
At that moment, the world fell into a deathly silence.
But Kenichi knew that behind this silence brewed destruction.
Sure enough, after one breath, a terrifyingly loud explosion sound resounded across the entire sky.
Boooooom-
Powerful flames expanded in a spiral shape.
Immediately after, violent shockwaves stirred up waves several meters high, spreading out in all directions.
Erza, Mirajane, and the others on Tenrou Island, hearing this terrifying explosion, felt their hearts suddenly tremble.
"Kenichi..."
Soon, the terrifying shockwaves and giant waves also swept towards Tenrou Island.
But fortunately, Freed's Jutsu Shiki blocked the storm and sea waves.
