Unbreakable Magic

Meliodas is wiping the front bar table of the Boar Hat Bar with a white tablecloth. He hums the theme to the Seven Deadly Sins. he bends down to pick up some more spray detergent, but when he stands up again, Asta appears to have already taken a seat at the table startling him.

Meliodas: (Oh Jeez. A Magic Knight! With no magic power? That's odd.)

Asta seems to observe the small bar, while fiddling with his seat.

Meliodas: (Regardless, I cant fight today.) Lucky you, It's almost closing time! What will it be?

Asta: HELLO!!! BARTENDER!!!

Asta delivered a sparkling smile, as he rubbed the back of his head.

Meliodas: LOUD!

Asta: Oh yeah, Captain sent me to hunt out the leader of an evil group. 

Meliodas: (Uh Oh) Really now? What are they called?

Asta: Well, this place calls them the seven deadly sins! And their leader is this really strong guy. I forgot his name, but I think he had something to do with wrath.

He brings out a wanted poster which was now a bit warped and disfigured.

Meliodas: (They sent the guy without magic to deal with me? Whoa! He must be crazy strong. Too bad today is harvest with Elizabeth. I really would have wanted to try him out.) So, what will it be?

Asta had already noticed Melodias's magic pressure's effect. He muses to himself.

Asta: (This is can't be wrong. Right? His magic is stronger than I've ever seen! Even the hair colour and height descriptions are the same. He has to be Wrath! Or he could just be a really strong bartender. I guess I'll have to find out for myself!)

There was a pin-drop silence.

Asta: Let's get straight to the point. You've caused enough trouble. Why did you kill him? 

Meliodas: So you're not an airhead after all?

Meliodas drops what he was seemingly preparing, he delivers a forced smile.

Meliodas: (In head) They're all just the same, aren't they? (Our of head) Well, magic knight, now that you know the truth, what do you want to do now?

Asta: (Called it. Time to engage.) It's time to face the consequences. I want to show you how Britannia felt.

Asta's Grimoire, which has totally been hovering around this entire time, trust me, suddenly opens itself, as Asta pulls out a sword from its pages. He slices at Meliodas but only breaks the table as Meliodas jumps back, dodging.

FIGHT!

Asta slices at Meliodas again who dodges. Meliodas pulls his sword and covers himself in darkness. He intercepts another strike, this time, a frontflip strike from the sky, causing Asta to flip backwards and regather himself. Meliodas gains newfound confidence.

Meliodas: (Let's see what works here.) Hatred isn't the only thing that drives strength. And trust me, you've got a long way to go before you can even scratch me!

Asta: Huh? Why so out of the blu-

Asta stopped in place, leaving an opening for Meliodas. He had used one of the Ten Commandments. Meliodas walks over to him.

Meliodas: Cause if you have hatred in your heart, (He points the sword at his throat) You can't hurt me.

Asta: Well I'm not done yet!

Asta uses Causality Break at the last moment to break out of the curse! The baffled Meliodas who can only mutter a "What?" Asta then slices through Meliodas' Darkness, hacking of his arm, and sending it flying. Meliodas punches his foe away and uses the darkness to catch his arm and pull it back onto his body before much blood can spill out.

Meliodas: That's new, he cut right through me!

He blocks another sword strike and pushes back Asta before cloning himself, these clones dash at Asta in different directions with blinding speed. As the camera rotates, Asta intercepts and one shots one in half, but gets hit in the side and the back by two more. Asta begins to coat more and more of himself in Anti Magic as he begins to just cleave through them with slashes, before using some of the borrowed magic he had on his sword on the rest of them. Then he dodges some stray beams on the floor by rolling to the side, shot by the real Meliodas. Who had somehow appeared behind him?

Meliodas uses Trillion Dark and begins to blast at Asta, who uses Black Slash to counter him.

Meliodas: Your magic, is strong!

Asta: Thanks! But I'm not done yet!

Meliodas: Neither am I.

Meliodas covers himself in even more darkness than usual, transforming into his assault mode. He engulfs his hand in Hellblaze and rushes at Asta before he can react, punching him out of the bar through a wall.

Meliodas: That shouldn't cost much hopefully.

Asta who has now transformed into his black form uses Black Meteorite. Which almost catches him off guard. Meliodas avoids him barely.

Meliodas: Whoa!

Asta: Almost!

Asta turns around still using Black Meteorite and starts to move so fast, he appears to have some afterimages, sending multiple Astas blazing at Meliodas, who sends out his clones to answer them. Unfortunately, these clones were obliterated completely by Asta's afterimages, who blaze so hard, that they fly into the air to meet Meliodas who had flown high to safety. And as the 5 Astas slash at the same time...

Meliodas: Alright, time to finish this!

An explosion of power obliterates the surrounding area blasting the clones to atoms. It sends Asta rolling into the dirt and green grass around him. The moonlight and dark blue sky now showcased Meliodas in his true magic form.

Asta: (The pressure of his magic is increasing! This is even more on Lucius! And if I get hit once... )(He dodges a few Hellblaze blasts) (I'm finished! Time to go all out!)

Meliodas: You must have worked hard to get to this level. I applaud you for that. But I know I can beat you! Thanks to the people who believe in me, I can beat anyone! Cause I'm a Knight!

Asta: Well you can't beat me!! I would rather die the give up!

Meliodas shoots Hellblaze and darkness at Asta and other various types of magic all at once. Asta uses his sword to absorb ALL of it. And shoots it back at him.

Big mistake.

Meliodas: You're done! REVENGE, COUNTER!

The super strong magic blast creates so much wind around the entire area, as everything begins to light up. Asta struggles to block it with his sword as the beam pushes him back.

Suddenly, 2 more beams rise from Meliodas's body. They slice off both of his arms, causing him to scream in pain.

Meliodas: I'll give you this much. You did try your best.

He flies into Asta, continuously punching across him over and over again. His bloody screams disturb the serenity of Boar Hat's environment.

Meliodas: But you've thrown away everything for this fight, only to lose. This will be your final sin, Magic Knight.

He flies into him, delivering a fatal stab to his midsection. This time, Asta can't even muster a scream. He just collapses.

Meliodas: I wonder how ripe those apples are.

He starts to walk away, whistling what he whistled at the very beginning of this fight.

Asta: No...I'm not...done...YET!

Despite his body being in tatters, despite every echelon of his body aching to the max, Asta, was not done yet.

Even while armless, Asta engulfs himself in Anti Magic, coating himself over and over again. And now, he walks slowly after two more swords levitate from his book, pointing forward. Meliodas delivers an immense blast of magic, but it wasn't enough. They first cleave through the blast, cutting through it like butter, until they're in front of a horrified Meliodas, who can't believe what he's witnessing. Both swords stab into Meliodas' body, despite everything. Asta speeds up his running, now holding his original sword in his teeth, running forward as he prepares a strike. Before Asta can hit him, he uses telepathy.

Meliodas: I'm sure you'll find out who truly did it. 

And just like that, Asta slices through Meliodas like he was made of butter. As both sides fall to the floor, they fade away instantly. Asta attempts to stand victoriously. Then suddenly, his legs turn to jelly. He stumbles over and falls on his ass. He sits up, looking at the moon, which shines on his body, tired from the long battle. 

Asta: I'll protect everything when I become the wizard king. Everything.

KO!
