Mard Geer Tartaros, the strongest demon in Tartaros aside from END.
After transforming into his demon form, his power would rise to an incredible level.
But now, Mard Geer didn't even have time to transform before Kenichi killed him.
And it was instantaneous.
Of course, given Kenichi's current strength, even if Mard Geer had transformed, it would probably only take one move.
After all, Kenichi could instantly kill even dragons.
In the entire Fairy Tail World, probably only Acnologia remains as someone Kenichi can fight to his heart's content.
Thinking of Acnologia, Kenichi shifted his gaze from Mard Geer's corpse to the sky, clenched his fists, and said with a face full of fighting spirit: "It's about time you showed up, Acnologia!"
In the original work, when Natsu fought Mard Geer, Acnologia appeared.
He even fought Igneel, who is residing within Natsu.
Based on Kenichi's current speculation, Acnologia would very likely come here as well.
Thinking about encountering Acnologia again and fighting him filled Kenichi's heart with immense anticipation.
"Seven years no see. I never expected you to have grown to such an extent!"
Just as Kenichi was anticipating the fight with Acnologia, a male voice suddenly came from behind.
Hearing the voice, Kenichi refocused and turned to look.
A black-haired man dressed in black clothes with a white cloak draped over his shoulders was slowly walking towards him.
Looking at this person, Kenichi's eyebrow twitched.
"Zeref!"
That's right, the man now in Kenichi's sight was the Black Wizard Zeref.
Seeing Kenichi's raised eyebrow, Zeref thought Kenichi didn't recognize him and explained: "Seven years ago on Tenrou Island, I saw you lead Acnologia away. It truly surprised me back then!"
Kenichi naturally knew Zeref was on Tenrou Island at the time.
Grimoire Heart had specifically gone to Tenrou Island to find Zeref back then.
"You came here just to tell me that?"
Kenichi raised his arm, adopting a ready-to-fight stance.
Zeref possessed an immortal body.
Kenichi also wanted to test whether his current strength could kill the immortal Zeref.
Seeing this, Zeref immediately raised his hand and said: "I'm not here to fight you. I'm here to..."
At this point, Zeref pointed a finger at the book Mard Geer had been holding.
The book instantly vanished from its spot. The next second, when it reappeared, it was already in Zeref's hand.
"...reclaim this. It's a very important item to me."
Looking at the book with the letters [E.N.D.] printed on the cover, a doting look appeared in Zeref's eyes.
Perhaps others didn't know who E.N.D. was, but Kenichi naturally did.
E.N.D. was Natsu, and also Zeref's younger brother.
To be precise, he was the strongest demon created by Zeref using the corpse of his younger brother, Natsu Dragneel.
'Natsu…'
Zeref looked at the E.N.D. book in his hand, a barely noticeable curve forming at the corner of his mouth as he thought to himself.
Then he refocused, lifted his head, and cast his gaze towards the distant sky, continuing: "Right now, the one you most want to fight probably isn't me."
"He is coming this way. Acnologia."
'Acnologia!'
Hearing Zeref speak this name, Kenichi immediately turned to look at Zeref.
But Zeref had already disappeared.
However, Kenichi could still hear Zeref's voice.
"If you can hold off Acnologia, I will come back for you. Fairy Tail."
"Come back for us?"
Hearing Zeref's words, Kenichi let out a light hum.
In the original work, Zeref, in order to obtain the First Master, who was the Fairy Heart, led the Spriggan 12 and the soldiers of the Alvarez Empire to attack Ishgar.
Zeref's mention of coming back likely referred to this.
But even if Zeref brought the Spriggan 12, Kenichi would still have no fear.
Back in the day, on the Western Continent, he traveled far and wide searching for the Spriggan 12 to collect their magic attributes.
Now, if the Spriggan 12 delivered themselves to his doorstep, Kenichi naturally wouldn't let the opportunity pass.
Of course, that was all for later. Right now, Kenichi needed to deal with the imminent arrival of Acnologia.
