Physics The Greatest Magic

The spear cut through her chestplate and passed right through her chest, leaving nothing behind. The ground which it crashed into looked like it had been trimmed off along a part of the boss's chest where the heart was supposed to be. 

Just like John had guessed, it wasn't going to be enough. 

The hole had already started to heal and the Boss was already moving towards him, She crouched down, and began to gather air under her legs before propelling herself straight at John who was in the air 

But before she could reach him 

*BOOM* 

The loud sound of thunder roared throughout the room as a Thunder beast bit on to her and slammed her down 

"Mihi Vindicta: Kirin Scriptor... Sorry." Translation: Kirin's Revenge 

The blue lightning beast with horns on it's head which seemed to have the body of a thin dragon. Roared as thunder echoed throughout the room and slammed the girl on to the floor of the Arena, cracking parts in the process 

As she held on to her spear, she tried to pierce it once they were on the ground, but the spear went right through it. 

"It's body is made out of lightning, It's useless." Said John 

The thunder beast let out another roar, before dragging her across the ground, straight on to the wall 

*BOOOM!* 

He dragged her across the wall nearly tearing the boss in the process, but before it could, as it let out it's final roar 

The boss's eyes suddenly began to glow a bright yellow colour along with her wings. 

The beast moved her from on to the wall before raising her back into the air, it planned to slam her back down on to the ground to finish her off 

After that impact on the ground and wall from such a big beast, there was no way her bones weren't broken. 

Right when it reached a reasonable height, which was above John who was in the air, it stopped and was about to do a turn before sending her straight back down. 

But before it could, another eye deafening scream could be heard from the boss, and another light Sphere was formed around her 

This time it had yellow electricity cracking through it, the sphere was formed around her and, because of that, the dragon lost it's grip over her, and now had the sphere in it's mouth with her inside 

It couldn't fully close it's mouth to break past the sphere 

"That's enough, Rikirin." 

Just as fast as it had appeared, the thunder beast disappeared 

Meanwhile, the girl slowly began floating down flapping her right wing and her left which had deformed from the impacts. 

"I'm surprised those wings are still intact." 

The boss was infuriated, the expressionless face it had was now replaced with an angered one 

"This fight has been long, but unfortunately, I'm going to have to end it now. I'm sorry." 

As she charged at John with her spear stretched out pointed towards him and the Sphere around her, he muttered it. 

"Cancel." 

But to his surprise the sphere didn't disappear nor did she slow down 

"I see..." John muttered as he stretched out his hand 

Once she was only a few feet away, she suddenly stopped, and in that instant, a distortion in the space occurred before a black sphere the same size as her appeared out of thin air, a few meters in front of her 

It was a black hole, dragging and pulling all the air around the area into it. The Space around them was getting distorted and the area got darker as if all the light was getting sucked in to the hole. 

This was because no light could escape the clutches of a black hole. When a small enough mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity. 

That was one of the concepts John had remembered learning after borrowing Zestari's power. 

John shadow stepped away and watched from the sides as the Black hole began to litteraly eat everything around it. 

The hole room lacked light, and the one was was in the worst spot was the boss. It was pulling her in, but instead of letting herself get dragged in, she began to quickly flap her wings at a speed much faster than before. 

But it was useless, she was getting dragged in slowly but surely. 

"NOW!!!" John shouted from the top of his lungs 

The sound resounded through the room as he amplified it with Sound magic 

Upon hearing this, it was unleashed, A large humanoid female shape made of wind and fire was formed in the area where John's two party members were at. 

It only formed a top part, but that shape along was big, around 10 x the size of John, truly gigantic. 

The humanoid shape was floating above them and held on to a flaming bow with 2 arrows drawn. One made of pure sharp wind while the other was made of pure blue flames. 

The string was released and arrows were propelled straight at the black hole. For were unbelievably fast for their massive size and were even spiralling together which gave it the form of a helix. 

"Stop. Attract." Said John right before it reached the black hole 

The boss lost control of all of it's body movements as it stayed in the sphere, before a force different to the black hole pulled at it. 

The boss was pulled in between the giant spiralling arrow and the black hole. 

*Voom* 

The spiralling arrows pierced through the defensive light sphere which surrounded the Boss before it hit it head on, Pushing it straight into the black hole which was already dragging it in 

The boss tried to put up a fight and even let out another ear-deafening scream as it tried putting up a fight, but it was useless 

It happened in an instant, She suffered burns and cuts from the arrows as it pushed her straight into the black hole, which devoured her 

Nothing remained, not even blood.
