Fairy Tail: The Fourth Master

Era, Magic Council's Headquarters.

All councilors are gathered in a spacious hall, talking about the news that spread like wildfire in the Kingdom of Fiore.

"What are your thoughts about this? With the return of the Fairy Tail's main members and the previous Saint, Makarov Dreyar, they will be more uncontrollable."

"What can we do about it? Not to mention sir Dragneel, even sir Warrod, and miss Fiana are supporting it. Now with Makarov's return, the Fairy Tail has four saints supporting it, there is also that Gildarts."

"That's right, there is nothing we can do. Besides, even though the other seven saints isn't directly supporting Fairy Tail, if we pushed them too hard then those seven will support them."

"What are your thoughts about this, Gran Doma?"

Then, the councilors stared at Grand Doma, who has been strangely quiet all this time.

A sigh escapes on his lips as he glanced at every councilors in the room.

"Let's just leave them be for now. Fairy Tail is valuable, if in case the Alvarez decided to attack."

....

Magnolia, at an open field in front of Fairy Tail guild.

Gajeel can be seen facing one of Fairy Tail's twin dragon slayers, Rogue Cheney.

"Gajeel..." Rogue narrowed his eyes. After seven years, he finally got the chance to fight his 'mentor' and prove himself that he is now much stronger than him. "....I am no longer that little apprentice you used to know."

"Gehee~! We'll see about that." Gajeel replied with a smirk.

A couple of Fairy Tail members are also watching from the side. Cana also set up his betting stand and proceed to take some bets.

Then, five cats suddenly walked out of the guild and immediately stood at the side, watching the two about to fight in excitement.

"Go Rogue!"

"You can do it Rogue-kun!"

"Fro thinks so too!"

"I'll support you Gajeel."

"Hmph, boys."

Happy then glance at Carla then back to the fight, before looking at Carla once again. Carla noticed this and couldn't help but ask,

"What is it?"

Happy remained silent and just stared at her, Carla already began to feel uncomfortable with his stare, right when she was about to tell him to stop, Happy took his gaze off from her and glance at Rogue.

He pondered for a moment before nodding his head. Angel-like wings sprouts from his back as he flew towards Rogue, causing the fighters who are about to fight, to stop.

"Oi, Salamander's cat, move away, this is not something you should get involve in. Shoo~ shoo~." Gajeel said with an annoyed expression.

Happy ignored him and whispers something into Rogue's ears that even with a Dragon Slayer's hearing, Gajeel couldn't hear what he was saying.

Rogue seems to be hesitating but then he nodded, and went to side, leaving Happy facing Gajeel.

"Oi~! Kid! Where are you going?! The fight ain't even started yet! Come back here!"

Rogue ignored him and stood beside his friend, Frosch, he then cast a glance at Gajeel.

"If you can beat him, then I'll fight you." Rogue said as he pointed at Happy, who is happily wagging his tail with a smile.

Carla and Lily stared at him dumbfounded. They have known Happy for awhile now, and aside from using fish as a blunt weapon, he can't fight or anything else.

Gajeel stared at Happy before turning his gaze back to Rogue, "You mocking me? You want me to fight this cat before fighting you? What can he even do aside from hitting me with a fish?"

"Do not underestimate him. Happy also fought in the war against the Smiling Reaper, he even survived fighting a Saint-class mage, he's far from weak." Rogue said and didn't say anything more.

However, his words are already enough to shock the tenrou group that are present in the fight.

Looking at the blue cat who is wagging his tail with a smile, as expected, no matter where you look at him, he doesn't look like someone who could fight.

"Well, he really couldn't fight. In that form of his anyway." The spectators turned their heads and saw Ultear walking out from the guild towards them.

Then, Erza, Mira, and Laxus also followed after her.

"What do you mean in that form of his?" Lucy asked while looking at Ultear.

"I'm also curious." Erza said as she stood beside Ultear, while looking at the blue cat who is facing Gajeel.

"Just watch." she replied and said no more. The others wanted to ask her but decided against it, the fight was about to start anyway.

"Alright! Be ready cat, I won't go easy on you." Gajeel said.

"Aye!" Happy nodded.

"Iron Dragon's Club!" Gajeel's arms transformed into an iron club that stretched towards Happy in great speed.

Happy spreads his wings and dodged the attack. Gajeel was a bit surprised, he didn't put too much power in that attack as he is afraid of hurting him, but still, its impressive that Happy managed to dodged it.

Gajeel continue attacking him with his iron club, however, Happy easily dodged all of them while flying around in the sky.

"Tsk." Gajeel clicked his tongue and decided to get a little bit serious, "Iron Dragon's Roar!"

A gray colored blast shot from his mouth to Happy, it was too fast that he didn't have time to dodge.

The roar hit him directly.

The tenrou group was worried about Happy, Erza already prepared to beat Gajeel up if something happened to Happy, her thoughts were shared by Mira.

Carla also looked worried, though no one here saw it as she quickly returned to normal, though if you look closely, you can see her worry in her eyes.

However, as the blast disappeared, everyone was shocked.

Happy can be seen still perfectly fine, he used his wings as a shield to protect himself from the blast.

Gajeel was pretty shocked, even though that roar is far from his full power, its still strong enough to destroy a large tree.

"Hehe~ surprised?" Happy smiled as he descended down to the ground. Then, he began to release strong magic power, though it couldn't rival an S-class, its still shocking.

"What is he planning to do?" Carla muttered with a narrowed eyes as she stared at Happy.

Then, Happy was covered by a bright light, as he grew taller and taller, when the light disappears, the Tenrou group has their eyes widened in shock.

What they saw, is a boy around twelve years old, with blue hair, blue cat ears, and blue cat tail.

"That's..." Carla's eyes were wide open. Happy, that Happy, the tom-cat who knew nothing but eat fish all-day, actually became someone amazing...

Happy cast a glance at Carla who is looking at him with a stunned expression, he couldn't help but smirked.

'Hahaha~! I'm cool right? I'm awesome right? Haha~!'
