Physics The Greatest Magic

"Ah, John. Took you long enough." Said The Bright Sword as he took another sip of his beer. 

John remained quiet as he watched The Bright Sword carelessly enjoy his drink.

"Want some?" The bright sword asked.

There was no reply.

"Is that so…" He muttered as he filled his cup again.

They were in the middle of an underground pub. It was empty and mainly dark from the inside. It also wasn\'t known by many adventurers and there were rarely new customers aside from the regulars.

That being said, at this time of day, it was completely empty. The bright sword was pondering as to how John had found him.

"So, you knew, huh?" The bright sword asked

Upon hearing this, John made his way over to the empty seat next to the bright sword, before wordlessly sitting still.

The bright sword who noticed this, raised his cup up to his mouth to take another sip, when suddenly.

*Crack* 

It shattered to pieces, causing sharp glass shards to rain down on the table.

"How long have you known?" He asked

The question was ignored and followed up with a simple order.

"Let him go and stop all of this." Ordered John

"It\'s too late for that the magic circle is already active unless you break it, lesser demons will just keep pouring out." Replied The Bright Sword before reaching out for another cup.

John was unsatisfied by the answer and began to release blood lust. His patience was running out.

"If you\'re talking about my body, it\'s too late for me. He already had control over my own thoughts, Haha…"

A wide unbecoming grin was formed on the bright sword\'s face as he muttered

"I\'m sure you know what that\'s like, judging how you\'ve experience it." Said the bright sword as he let out a few giggles

The calm blood lust which was being directed at the bright sword had leapt to another level b coming more intense and concentrated. John\'s intentions weren\'t being hidden at all, he wanted to kill it.

However, the bright sword ignored this.

"I\'m more concerned about how \'that\' demon lord hasn\'t taken over your body yet… Actually, come to think of it, there were reports that he did, yet somehow you took-"

Before he could finish, he was interrupted by John who suddenly appeared behind him and slammed his face on the table.

*Slam!* *Thud!*

"I\'ll just force him out-"

Before he could finish, John leapt a few feet back, landing on top of a table, before leaping off of it.

Not even a second after, the area in which he was standing was struck by countless pointy shapes. formed by darkness which had emerged out of the shadows. There were swords, spears, poles, anything sharp which you could think of. 

What\'s more it completely blended in with the environment, having made it nearly impossible to detect.

"I knew something was up. Good thing I came, huh?" An unknown voice asked

John turned to the stairs where the voice was coming from and from there, he saw it.

Short spiky black hair and a straight lined scar going down his right eye straight to his mouth. A man in a cloak. He stopped right at the bottom of the stares. His attention wasn\'t on John, but rather, what was behind him.

*Clang* 

The Bright Sword who had tried to launch a surprise attack on the distracted John, ended up hitting something hard in the middle of his swing, something which he couldn\'t see.

Following that, weapons emerged out of the shadows at high speed, each aiming straight at John. However, all they ended up hitting was each other, as John vanished without a trace.

The man who had stood at the bottom of the stairs, then looked up only to see john above him, with a swing from his dagger, in motion heading right at him.

*Slash*

John felt connection, but that quickly after turned out to only be the trace of darkness left behind as the man vanished.

"That was close!" 

His voice came from the other end of the room where the bright sword was standing. John tightened his grasp over his dagger before turning over to them.

It was a two versus one and they were still holding back, things were definitely going to be rough for John but he didn\'t care.

"This form is killing me…" Muttered the bright sword

Shortly he said that, there was a quick and sudden change in the fluctuation of magic in the room. Condensed and pure darkness emerged. The darkness was intense and heavy that it caused The air to turn impure.

As this happened, the Bright Sword\'s entire form began to change. His Blonde hair had now turned completely dark. His deep blue eyes had turned pitch-black and the metal of his Golden sword had somehow began to peel.

He was transforming, however for John, now was the time to strike. 

John shadow stepped directly in front of the Bright sword, with two vertical swings in motion, heading straight towards The bright sword\'s head, when suddenly.

*Clang*

He ended up hitting something hard in the air, he took a glance at it, before shadow stepping next to The bright sword and swinging again.

*Clang* 

He was stopped again. It was some form of condensed dark magic which kept blocking him. Upon seeing this, John sent a kick straight at the other black-haired man only to hit thin air.

He had disappeared once again. The instance that this happened, a cut was formed on John\'s cheek as he tilted his head back.

He had barely avoiding a sword thrust which was aimed straight at his head, before shadow stepping back to the stairs.

Upon seeing how there was no way to physically get past their defense, he decided to settle it all in one heavy attack.

A strange dark Armour began to form over the Bright sword who\'s sword was turning darker and darker,  The grin on his face showed no signs of fading.

"What\'s wrong? Not gonna-" 

*VOOOM!*

The bright sword was interrupted by a dark trident which was propelled straight at them. He wasn\'t sure why, but despite having a barrier to block attacks, his instincts and senses were screaming at him to dodge it.

But it was too fast. 

*Splurt*

They were underground so the trident went past the bright sword and disappeared into the earth. Leaving behind a completely shocked Bright sword behind.

*Whistle* 

"He really got you with that one." Said the black haired man as he watched

*Splurt*

Blood spurted out of the Bright Sword dying the wooden floors and tables in a dark red as it did so. The bright sword slowly turned down to look over at his wound, to see how big it is and his eyes widened when he did.

His entire right arm was missing. What kind of magic was it? He wondered.

\'If I hadn\'t avoided it in the last second I would be-\'

The bright sword didn\'t even bother to finish the thought when he noticed countless magic circles forming in front of him. All of them had the very same trident forming inside of them.

There was no where to run or hide. His transformation wasn\'t complete so beating them in speed would be unthinkable. He had miscalculated.

"FU-"

The bright was interrupted for a third time as for a moment, his vision was clouded by darkness. Next thing he knew, he was standing right outside in the shadow infested roads of the village.

"Why did you help me…?" The Bright sword asked 

"Because I lost the bet, now I don\'t owe you anything, right?" He asked before pulling out his clock watch.

"H-Haha… Al-" 

*Crack*

Two horns suddenly grew out of the bright sword\'s head, causing him to quickly lose conscious. He fell over backwards onto the ground, his breathing becoming more and more frequent as he did so.

In that moment, as if he were some sort of magnet, all of the darkness in the area around him, was being forcefully dragged into him. No amount was enough, it just kept on sucking everything in. The sound of metal being banged could be heard as his dark Armour began to develop, and grow.

His dark sword had also began to grow as it fed on the lesser demons which roamed the street, they were all gathering up and heading towards him. He was absorbing their power. 

"So it\'s starting…" The black haired man muttered as he hung his head. "That\'s just perfect…" He then added with a grin

He then looked up at the blue sky before muttering.

"Staying here might get be caught up in the cross-fire… I guess it\'s time I-" 

*Slam!* *Crash*

He went crashing into the building beside him as he was kicked straight in his blind spot, while distracted. However, it wasn\'t over.

As he flew from the momentum, John appeared over him was again, with an Axe kick in motion, landing perfectly in the middle of his face before he was slammed straight down onto wooden floor of a shop they had broke through...
