Fairy Tail: The Fourth Master

"Gildarts...lost?" Gray stared at Gildarts who was thrown away like a ragdoll, his eyes widened in shock.

He then stared at Natsu, who haven't even move from that place since the fight began.

He clenched his fists and gritted his teeth, 'is the gap between us already that wide? I can't accept this, I need to train, If flame-brain can be that strong, then so can I!'

Gajeel beside him is also thinking the same thing.

Natsu helped Gildarts to stand up and they began to walk back inside the guild, the others also followed behind them.

"Natsu-sama," Natsu was immediately greeted by Kagura the moment he went inside the guild,

Natsu smiled at her and head towards the bar and order some beer. Makarov and Gildarts followed behind him and sat beside him.

"Welcome back master~," Ultear smiled and pinched his cheeks, causing him to furrow his brows.

"Stop that." Even though he said that, he made no effort of taking her hands away.

"Natsu!" Hearing someone calling to him, he turned his head and saw his partner, walking towards him.

"Lucy." He smiled and waved at her, Lucy smiled hurry towards him, however, Natsu suddenly flicked her forehead,

"Ow~!" She held her forehead in pain and glared at Natsu,

"That's master for you.." He smiled and c.a.r.e.s.sed her forehead with his thumb.

Lucy blushed in embarrassment due to his sudden and unexpected action. She really didn't expect that the Natsu she knew has this gentle side of his.

It is something that the old Natsu would never do.

Then, Wendy, walks towards him, "Nat-..M-Master?"

Natsu smiled and look at her, he ruffles her hair, causing the girl to pout and swat his hands away,

"Hello Wendy, you're still small."

"Urgh-!" An invisible arrowe hit her nonexistent c.h.e.s.t as her eyes lost its colors,

Then, Gajeel, Gray, and Laxus also approached him. Laxus folden his arms with a smirk, while the other two are grumbling.

"You have gotten really strong, Natsu, or should I say, Master?" Laxus said with a smirk, while the two beside him looks gloomy.

Erza, Mira, and Fiana also walk towards him, the 'demon' and the 'saint' has a smile on their faces, while the knight seems to be in deep thoughts.

"I really didn't expect for you to become the guild master, Natsu, or rather, Master." Mira said with a smile as she stood beside Natsu, causing the three girls to frown.

"I didn't expect it either," Natsu replied with a smile as she stared Mirajane's eyes, causing the take-over mage to avert his eyes due to embarrassment.

Kagura was fiercely glaring at Mirajane, it took everything she had just to stop herself from pulling out her sword.

"Carla I miss you!" Happy suddenly appeared beside the white cat that is standing beside Wendy, and hugged her.

(A/N: I actually forgot about them)

"Guh-?! Let go you Tom-cat!" Carla tried everything to shake Happy but to no avail, she isn't strong enough to do that, "Your snot! Your snot! Its messing up my dress!"

"So this is Happy's girlfriend? She's indeed pretty." Lector's voice sounded behind Happy.

"Fro thinks so too~!" Frosch also agreed while standing beside Lector.

Panther Lily was standing beside Gajeel and notice the two new exceed, he saw them earlier but haven't had a chance to talk to them, so he went towards them and greeted them.

"Hello, you two are Exceeds as well?" Lily said as he extended his paw, "I'm Panther Lily, nice to meet you."

"Hello, I'm Lector, and this Frosch." Lector shook his paw and introduced himself along with the cat that is hiding behind him.

"By the way Natsu," Makarov called out, as Natsu turned towards with a smile on his face.

However, when he saw the serious expression on Makarov's face, he lost his smile and turned serious as well.

Makarov drank a whole mug of beer in one ago, wiped the foam on his lips and turned to Natsu, "Follow me."

Natsu nodded and followed after him towards the master's office.

The others were confused and wanted to ask what's going on but Guildarts stop them,

"Don't bother," he said as he drank a beer from his mug.

"Why? We wanted to know what's happening," Gray said with a frown.

"It probably some serious stuffs, the old-man's face is quite serious earlier, probably some secret that is only pass down to the guild masters."

"That's possible." Erza added while nodding her head as she stared at the floor above.

...

Master's Office.

Natsu sat on the chair while Makarov sat on the table. Natsu glance at glance at Makarov with his eyes narrowed,

"What is it gramps?"

Makarov stared at Natsu with an incredibly serious face, then he pointed his finger below, as Natsu's eyes widened.

"My secret stash under the desk, did you read it?" he asked with a pretty serious face, but with a perverted smile.

Natsu almost fell down from his chair, the tense and serious atmosphere disappeared. He stared at Makarov dumbly and couldn't help but let out a wry smile.

"Yeah, I took a peek," Natsu admitted, "but seriously gramps, what do you want to talk about? Is it about that 'thing' in the bas.e.m.e.nt?"

"That's right." Makarov nodded, as he lost his perverted smile, "So? Did you saw it?"

Natsu shook his head and gave a wry a smile, "I didn't, but I felt an almost endless amount of magic power coming from it."

Makarov nodded and jumped off the table, "Come, follow me. It is, after all, something that all Fairy Tail's master should know."

Natsu followed after him as Makarov leads him in an underground passageway.

Natsu has already been here before, so he quietly followed after Makarov until they reached the place where a large door can be seen.

"This is it."

Natsu nodded, he felt it before, but even so, the amount of magic power he was feeling still shocked him.

No matter what is at the other side of that door, it is something that should not be known to others.

Makarov opened the door and motioned for Natsu to come in.

The moment Natsu went inside, he was immediately greeted by a sight that shocked him to the core.

His eyes widened and words seems to be stuck on his throat,

"That's..."
