I had changed the title as the original title does not sound natural in English. Writing battles is not my specialty. Pardon me for lack of detail.

In the original version I needed to consider the use of the scenes to differentiate between Natsu and Tsuna when they battled Jellal. I decided to differentiate with their outfit. Tsuna wears the vest while Natsu gets a T-shirt.

Chapter 17: "Master" VS "Apprentices"

Tsuna panted hard. His head felt heavy. He was supposed to reach his Teacher before the firing of Etherion. Even by the name of Fireball, was he too late? Tsuna had regained his awareness. He had sent Happy away to check on the others in order not to get them involved.

He looked around and realized that his surrounding had changed into crystal-like structure. His eyes widened when he found his Teacher standing right in front smirking at him.

"I had been waiting for you. I thought S Class mage of Fairy Tail Tsuna, the Fireball would reach me before the firing. Looks like I had overestimated you. I had disposed of the foolish woman who somehow got here due to the impact of the Etherion to kill time while waiting for you." "Jellal" pointed at a fallen figure at the side.

"Erza?" Tsuna yelled. His fist was burning.

"Why? Why did you do that? Why did you betray everyone? Betray Erza? You even cheated my brother? All these for the sake of your so-called plan of freedom? " Tsuna was burning in fury.

"Well well… I see that you are angry at these trivial things. All these are just as transient and short-lived. That woman is just foolish. In order to please me, she will act like a lady. But I must applaud her for she is smart enough to get a divorce. Speaking of idiot, your brother is most idiotic of all the mages I had known of. I had never seen someone so dim-witted to the extent that he will even screw up a simple mission to collect my order from a shop. Sometimes, I really wonder how he brought you up." "Jellal" remarked sneering at him. This time he really had gone too far with his insult. Tsuna could not believe his ears.

"What did you say? You better retract your words. You have no right to insult Erza and my brother!"

"Depending on your performance, I may consider. Come at me. Let's turn your training into actual battle!" "Jellal" raised his hand beckoning Tsuna to take him on. Tsuna accepted the challenge without hesitation.

Tsuna came charging at him upfront giving him waves of punch and kicks of which "Jellal" dodged at ease. He knew his movement too well. There was no way he would be hit. "Jellal" thought as much until he was caught in surprise when Tsuna landed a punch on his stomach and used his head driving him crashing against the Lacrima across the arena.

"Fire Dragon's Roar!" Tsuna spit fire at "Jellal" before he got a chance to retaliate. He knew very well he should not underestimate his Teacher who was a Wizard Saint. He jumped back and landed on his feet using one of his hands to balance himself while waiting for the smoke of the explosion to clear off to see if he had succeeded.

"Jellal"'s voice rang out as the smoke cleared. Tsuna looked up cautiously.

"Just as I thought. According to the information in my head, you are reckless in battles despite being an university graduate. Did you pass your S Class with brute force like this? Don't make me laugh. To think you have yet to progress since then. As expected, you are just as self-conceited as me. Facing me alone is a grave mistake. I know you too well because I'm your Teacher!" "Jellal" flung out his burning coat and he lunged at him at blinding speed.

"Heavenly Body Magic?" Tsuna noticed that "Jellal" had vanished and he was being plummeted blows after blows repeatedly by his Teacher.

"Grand Chariot!" Seven magic seals appeared before "Jellal" which then blasted at Tsuna resulting him to fall from the impact of the explosion. Tsuna was rendered incapacitated.

"Not bad. You are still in one piece after taking direct hit from my Grand Chariot." "Jellal" remarked seeing his fallen body. "You won't be that lucky next time."

Just when "Jellal" walked away from where Tsuna was. He sensed an incoming attack which he took it at ease.

"Eh? To think you can still fight my idiotic disciple…" "Jellal" clenched his fist flaring with his magic power. Facing him was Natsu who just managed to get there. "Seems like I had underestimated you. I thought you had lost your magic power and won't be able to come here like Ultear said you will."

"So what if it is me?" Natsu growled at him in fury. "And what did you call me? Do you have any nickname any worse than this? I even have people who called me a tool, you fake."

"Oh. I see that you know the truth about me? If that's the case, I shan't say any further, let's get straight to the point. Not even the real Jellal had fought you in real battle. So let me, as a fake have the honour to challenge you."

With that, Natsu battled the fake Jellal. They were observing one another. "Jellal" was well aware that Natsu was much more experienced than Tsuna in his moves but he was just playing with him. Natsu aimed a kick on his jaw which "Jellal" dodged at ease. He was smirking when Natsu tried his might roaring a torrent of fire at him. "Jellal" leapt up to the air with his Heavenly Body Magic.

Natsu realized that his magic were exactly the same as the real Jellal. Jellal have not really trained him in magic himself hence he was not aware of his real power as a mage. Even so, Natsu was not confident of defeating a Wizard Saint level mage but in order to protect his younger brother and change his fate, he had to do it. He would give his all. As an elder brother to Tsuna, this was as much as he could do.

"Jellal" sighed as he noted the fire flaring on both of his fists. "You are indeed an idiot. Even your S Class younger brother who is more powerful is not my match. It's much safer for you to dig a hole and hide yourself so that you can live longer. But it is too late. I'm going to take you out here!"

In an instant, "Jellal" leapt to the air he summoned Grant Chariot hitting Natsu repeatedly creating waves of explosion to show off his power. Natsu screamed in pain when the lights hit him directly and he collapsed. Is that it for him? Why was he so weak? Can't he do something to change his brother's fate? He groaned in frustration. The poison in his body was acting up again. Natsu bit his lip in great pain.

Tsuna thought he saw himself fighting with his Teacher in daze. "Told you. I'm strong." He smirked as he watched the figure battling "Jellal". He gradually became awake. He saw that person crashing down near him. Tsuna realized that it was his twin brother who had been battling him when he was out cold. He watched "Jellal" walking around inspecting the damage of the tower after he was done with Natsu.

"Damn. I must have gone overboard. It would be dangerous to damage the Tower any further. The magic power is starting to leak out. I need to guard it until Ultear comes here with the sacrifice." "Jellal" muttered to himself.

Tsuna just got a great idea. Trembling, he struggled to pick up pieces of Lacrima and threw at "Jellal" who was wondering what he was up to. After throwing a few pieces, one of them finally hit him. Tsuna chuckled.

"That attack hit." He struggled to get up. "So breaking this Tower or was it called Lacrima. That's bad right?" "Jellal's" eyes widened in horror. He had heard him.

"Rotten luck for you!" Tsuna gathered enough strength and landed a punch right on the ground causing it to crack.

"Stop it!" "Jellal" shrieked. He would not be able to complete his mission if the Tower was destroyed.

"Guess what? Destroying things is my specialty. Not even my brother knows this. The damage I caused is much greater than my brother!" Tsuna stood up as he looked at his brother who was shaking from pain.

"Brother, you just watch my battle. I had witnessed your battle with this bastard. You were great! No wonder he wanted to take you in as his disciple. Leave the rest to me." The flame on Tsuna's fist rekindled. "I'm now more fired up than ever!"

"Jellal" was really flared up this time. "You little brat! I will make sure you regret standing up again!"
