Jin opened his eyes widely when he heard Mercphobia's words. There's only two people that could make Mercphobia say that words.
Powerful...
Mercphobia say that word to the one that's approaching them. It's either Zeref or Acnologia. One of this two was approaching them. If it's Zeref then it probably won't turn into a battle but if it's Acnologia there's only one outcome and that is battle.
Jin looked around him at Caramile, Ur, Eclair, Momon, Jellal, and Mercphobia before he looked at the approaching Gildarts. He tried to think things that could let him escape this problem. He have Mercphobia on his team and he could stop Acnologia but not defeat him. There's a people here that doesn't have any battle power. Especially Caramile, Mercphobia will hold back as long as Caramile is here. He don't want the aftershock of his power to injure this girl so he probably hold back.
He turned his head to Gildarts. Gildarts fought Acnologia in the anime and it leave him heavily injured.
"Oh? Your mask and that insignia! Where did I hear it?" Gildarts said while looking at them. He ponder where did he heard those as it's quite familiar to him.
Ur looked at Gildarts then she took a glance at Jin. She immediately notice his trouble face. So she asked him, "Is there something wrong Jin?"
Jin looked at her and said, "Mercphobia said that there's someone approaching us and it's powerful. For him to say that... There's only two person on this continent that could make him say that. It's either Zeref the black wizard or Acnologia the dragon king."
"What?!" Ur was stunned when she heard his words.
Not just her, the rest of them was shocked too.
Jin know that they wouldn't be able to escape Acnologia as he have a powerful smell.
Momon looked at Eclair and asked, "Eclair, who is this Zeref or Acnologia?"
Eclair shook her head. "I don't know much about them but I heard that they were powerful."
Damn! Jin cursed in his mind. He have a chance to talk to Eclair but one of this person decided to show up. He could see that Eclair was move at his words at that time.
Jin took a deep breath and calm himself. He looked at Gildarts and asked, "If I presume you're Gildarts, right?"
Gildarts snapped out of his dazed when he heard his words. He looked at Jin with widely opened eyes, "I don't think that I'm famous enough for you to know me."
"Yeah. You're not famous enough for me to know you but I heard of you from Makarov." Jin said to him.
"Eh?! You know Master?" Gildarts was surprised.
"Yeah. And I'm a member of Fairy Tail on the dark side of the world." Jin nodded at decided to tell him.
Gildarts frown at his words. He looked at Jin and the rest of his group. He then asked, "If your a member then, where's your guild insignia?"
"I don't have that because I created the dark guild to infiltrate the Baram Alliance. There's also spy of Fairy Tail on Magic council. So it's not nothing to put a spy from the enemy." Jin said as he shrugged his shoulder. He then turn serious and said, "I would like you to do one thing for me."
Gildarts didn't know if he could trust them or not. If this man have the Fairy Tail insignia then he wouldn't mind doing thing for him because everyone in the guild is a family.
He opened his eyes but before he could say anything he heard a voice behind him.
"I smell a dragon."
Gildarts turned around and saw a muscular man with a long, spiky, dark blue hair.
Ur looked over and was shocked when she sense the magic power inside Acnologia. It feels like she was looking at the magic power of Mercphobia but it was more stable than Mercphobia.
"Jin, don't tell me that is..." Ur said.
"Yeah. That's Acnologia." Jin nodded solemnly.
Mercphobia opened his eyes widely as he looked at Acnologia. All the memories of his past about Acnologia came into his mind. The killing spree that Acnologia did became fresh in his mind. He remember the fear he felt when he decided to leave the continent just to escape from him.
"Water Dragon-sama! Water Dragon-sama! What's wrong?!" Caramile asked in a worried tone.
Mercphobia didn't heard her as Caramile started to shake his body.
Jin noticed that Mercphobia's magic power was getting out of control. He quickly grabbed Caramile and shouted.
"GET AWAY FROM MERCPHOBIA!!"
Jin didn't think that this would happen. This was not in his calculation.
Jin, Ur, and the rest quickly retreated back tens of meters away from Mercphobia.
Boom!!
A powerful magic power burst out of Mercphobia. It shook the whole area and force them to retreat tens of meters away from him.
