A familiar roar echoed through the sky, and Zeref's expression changed instinctively.
"Acnologia."
However, he quickly let go of the worry in his heart.
Forget the Black Dragon, even if Ankhseram, who cursed him, came in person, with these Group Members here and the Group Leader in charge, what did he have to fear?
Unlike Zeref, the Group Members were somewhat confused when they heard the resounding dragon's roar.
It wasn't until Beryl said "Acnologia" that everyone came to their senses and began to observe the Black Dragon speeding in the distance through the projection on the island.
Its skin was as black as ink, engraved with strange patterns, giving off a sense of disaster and defilement.
"That... is the Black Dragon?"
Shiraori released her spiritual power, sensing the surging magic power transmitted by the Black Dragon, and was somewhat surprised.
It was far stronger than Araba, and perhaps even Ariel would not be its opponent.
In her world, the Demon Lord Ariel was the closest existence to a god.
From Shiraori's sensory perspective, the Black Dragon's overall strength far surpassed that of Demon Lord Ariel.
If it weren't for the soul fragment left by Evil God D when she became a god, she might not have been an opponent for this dragon either.
"He... is very strong," Shiraori murmured.
"Kumoko, even you can't win?" Rimuru was held in Kumoko's arms, looking at the expressionless Kumoko with closed eyes, a question mark hanging over the blue Slime's forehead.
Kumoko was a big shot designated by the Group Leader, who had already become a god.
If even she wasn't an opponent, there probably weren't many people in the group who could be.
The Group Leader was one, Vegeta was one, plus the uncertain Lumine; as for the others, there seemed to be none.
"I don't know. That dragon's physical magic resistance is very strong, and I'm not sure if my magic can affect it, but if I attack its soul, I can win."
"Eh... Is it that powerful?" Rimuru looked at the huge black shadow on the screen, like a flying disaster.
"By the way, Kumoko, the way you talk has changed so much. Are you really socially anxious?" Although Kumoko was holding him, her speech felt completely different from the free and easy way she communicated in the group.
Kumoko was silent and did not answer.
However, inwardly she was thinking:
It's good that you know, why say it out loud, and keep rubbing against me?
"Hey, are you interested in fighting the Black Dragon?" Uchiha Madara, who had been sitting cross-legged, stood up. Having eaten the Spirit Tree fruit, he felt refreshed. Although his strength hadn't increased, his spirit and soul had been cleansed.
Uchiha Madara clearly felt that he was closer to the Six Paths level.
He wanted a satisfying battle.
"A dragon?"
Asakura Hao also got up, patting the dust off his cloak.
"It's worth seeing."
"Since that's the case, I'll go too. I'm also curious about what a human who turned into a dragon is like." Aizen Sōsuke took a sip of his wine and put down the glass.
"The Black Dragon is very strong. You could die if you're not careful."
Zeref's voice rang out.
Zeref, Mavis, and Precht were walking towards them.
"Are you scared? As a Grand Mage, you're afraid of a dragon, even if that dragon was once one of your kind." Uchiha Madara's face showed a mocking expression.
Precht, who was beside him, wanted to argue for Zeref. After all, after the recent narration, he knew many things that had happened.
However, before Precht could speak, Zeref reached out and stopped him, shaking his head slightly, signaling Precht not to speak carelessly.
"Uchiha Madara, you are not the Black Dragon's opponent. I have fought the Black Dragon several times, and his strength is above yours."
"Are you saying that you are that guy's opponent?" Uchiha Madara said coldly.
Anyone would be unhappy if someone pointed out their inadequacy to their face.
"No, if not for my immortal body, I would probably have died at the Black Dragon's hands. He is very strong... one could say that Acnologia's defense is the amalgamation of all dragons." Zeref shook his head.
"So what? I need him to make me stronger, that's all." Uchiha Madara retorted, "Zeref, I finally know why you can't become a strong person, because you don't have that courage."
Uchiha Madara laughed, "Everything you've done is just the obsession to revive your brother. Once you lose that obsession, you're just a talented guy, nothing more."
"Please don't say that to Mr. Zeref." Elaina ran over, hoping to stop the argument between the two, although she knew that with her ability, she couldn't stop them at all.
However, Zeref had taught her before.
In a sense, he was her teacher, so she couldn't remain silent.
"Elaina?" Uchiha Madara suddenly laughed, "Zeref, if it weren't for your obsession and enough time to accumulate power, you wouldn't even be as good as Elaina."
"Uh..." Elaina's face stiffened, and her mouth twitched.
How did she, who came to mediate, seemingly become the fuse?
"Everyone has their own way of life, there's no need to be demanding." Beryl said while eating a pineapple bun, her mouth stuffed full.
"For example, can you make Senju Hashirama change his naive views?"
"This..."
He couldn't change Senju Hashirama for anything.
Before the Five Kage Summit, he almost grabbed Hashirama's ear and roared.
Did that guy listen when he told him not to divide the Tailed Beasts?
"Go if you want to. Zeref is just worried that someone will die here, killed by the Black Dragon."
"But I'm different." Swallowing the pineapple bun bulging in her mouth, Beryl slowly said, "I'm not worried at all. I don't care whether you live or die."
Uchiha Madara: "..."
Although it was the truth, it always felt a little off when he heard it.
What happened on the alternate Tenrou Island was unknown to the real Tenrou Island.
Fairy Tail, who was preparing to leave, and the members of Grimoire Heart, who were waiting for Precht to return and had not yet left.
Upon hearing that terrifying dragon's roar, they immediately felt their hair stand on end.
Especially when they saw the figure getting closer and closer.
"Acnologia!"
Makarov's face was tense, and his eyes showed a look of dread.
"Why is Black Dragon Acnologia appearing on Tenrou Island?"
"Natsu, hurry up and go! This is the Black Dragon." Makarov used magic to try to buy time for Natsu and the others to escape Tenrou Island.
However, Natsu and the others still stayed.
All their magic was directed at the Black Dragon.
But how powerful was the Black Dragon? The magic of the Fairy Tail members couldn't even break its defense.
Even Makarov was easily knocked to the ground.
Being bombarded with magic by everyone on Tenrou Island, although it wouldn't cause injury, it was uncomfortable.
Acnologia was somewhat angered. It flapped its wings and flew up, preparing to completely destroy the entire island.
At this moment, everyone seemed to be helpless.
"Well done, children of Fairy Tail!"
A young girl slowly descended from the sky, landing beside the Fairy Tail members.
"You... who are you?!" Makarov's expression was filled with shock when he saw the girl's face.
"You can call me Mavis, or Mavis Vermillion, either is fine."
"First... First Master!" Makarov looked at the young girl in front of him in disbelief. Her face was like that of a fairy, but how could she be alive? She had clearly... died a long time ago.
In Makarov's mind, the conversation between Zeref and Hades, mentioning Mavis, suddenly surfaced. Could the Mavis they mentioned be the First Master?
"Hmm, we can talk about anything else later. The upcoming battle is not something you can participate in."
While Mavis was speaking, the Black Dragon, who was preparing to attack, was heavily sent flying.
Then, Zeref descended from the sky and came to Mavis's side.
"From now on, it's none of our business."
It was Zeref who had just sent the Black Dragon flying. Although he was not the Black Dragon's opponent, he could still throw it far away while it wasn't paying attention.
