Physics The Greatest Magic

John stood on top of the cube with his arms raised up into the air, clenched into a fist. There was no doubt about it. He looked like an angel. 

*Thump* 

Serena and Lydia who saw this could feel their hearts shake as they witnessed it. John stood on the quarter of cube as he did this. The cube however seemed smaller and less than before. After taking a closer look they noticed it. 

Where there was supposed to be a large cube, only remained a quarter which was the part in which he stood on. 

------------------------------ 

The bright light disappeared off of John\'s eyes as he breathed out heavily with his arms still raised up. The Large dark cube, turned a palish purple as it had lost a large portion of itself. 

"What... What happened...?" John asked as he panted heavily 

He looked around and seemed surprised by his surroundings. The last thing he could remember was being on the air, yet there he stood on top of a broken cube. 

His surroundings were slowly crashing down, yet he paid attention to none of that. Debris fell past the cube straight down onto the abyss beneath, yet he could barely notice it. 

During the state of confusion, the single thought which John couldn\'t believe he had forgotten, rushed straight into his mind. 

"The demon!?" 

John desperately looked around to see if he could find it, as he used deprehendre. For the first few seconds, he found nothing. But right after that, through the corner of his eyes, he could both see and feel it. 

An emerging darkness coming out from within the cube, at the edge beneath him. It was slowly increasing and began to make itself throughout the room. 

John slowly turned towards it, and when he did his eyes widened. The darkness had taken the shape of a humanoid being, just like the demon. Only this time, it had no body. Just a humanoid shape made purely of dark air. 

As John stared at it, he could feel something within him being attracted to it. It was almost as if it was calling out to him. 

In a semi-hypnotised state, John stretched out his arm towards it and in response, it made it\'s way towards John. 

"W-What\'s going on?" Lydia asked as she watched this 

"That demon... It\'s calling out to him?" Serena muttered 

"Isn\'t that a bad thing?" Lydia asked 

Serena who heard this, slowly bit her lips as she replied. 

"I\'m not sure..." 

She then looked at Mrs Sylvia and noticed an unchanging expression on her face. 

Was this part of the plan? What will happen if that thing goes into contact with John? These questions filled Serena\'s mind but before she knew it, the words were already coming out of her mouth. 

"JOHN!!! SNAP OUT OF IT!!!" She shouted with all her strength 

Somehow, despite all that distance. Her voice was able to reach him, within the deep, abyssal silence. 

"Huh?" John asked as he finally snapped back into reality. 

He turned towards the sound of the voice and found Serena and Lydia waving at him. Master Sylvia was also there, just quietly staring. 

But by then, it was too late. 

"Sere-" 

*Thump* 

John was interrupted as the dark air figure placed it\'s hands on him. In that instant, for him, everything turned pitch-black. 

"ARGH!!!" John grunted out 

He couldn\'t see anything, all he could do was both hear and feel pain. Whispers passed through his ears as they resembled whails of help. Too quiet to be heard, yet loud enough to be understood. 

The painful sensation akin to that of being pierced flowed throughout his body and there was nothing he could do to stop it. 

"It\'s started." Stated Master Sylvia 

"GAH!! AAAAHHH!!!" John cried out 

The pain didn\'t stop there. It only continued to increase. Because of this, John fell to his arms and knees as he repeatedly slammed his arms on the ground beneath him. Cracking the ground as he did so. 

He began strengthening the body in an attempt to lessen the pain, but it turned out to be useless. The pain wasn\'t coming from the outside, but from within. 

"S-SA-SANA!" John shouted out 

Steam began to let itself out of John\'s body as the pain began to decrease. The feeling of being trapped in an enclosed space with simply spikes, luckily began to fade. 

But it still remained strong. Sweat began pouring down John\'s face and chest as steam continued to be let out. 

"What\'s happening to him!?" Serena asked as she was about to make her way towards him to help 

However, before she could she was stopped by Master Sylvia who grabbed on to her shoulder. 

"Let go." Said Serena as she glared at Master Sylvia 

Master Sylvia simply shook her head and increased her grip over Serena\'s arm, seeing as how she had no intentions of stopping. 

It hurt but Serena didn\'t back down. She grabbed on to Master Sylvia before trying to move it away, only to realise that it wouldn\'t budge. Seeing this, Serena\'s hair began glowing, once again. 

"Mrs Sylvia... Don\'t try to stop me, can\'t you see?! He could die!! Don\'t you care about your own student?!?" Serena shouted out 

Serena wanted to avoid a confrontation as Ariel was still unconscious on her back, and there was no telling what Master Sylvia could do. 

"He won\'t die." Replied Master Sylvia as she pointed towards him 

Serena looked over to see what Master Sylvia was talking about, and as she turned her back to her. 

*Pierce* 

Blood slowly began to drip from Serena\'s mouth as the painful sharp sensation suddenly crashed into her body. 

"A-A..." 

She slowly looked down only to see a dagger sticking through her stomach. Blood dripped from the wound as it throbbed in pain. No matter how hard she tried she couldn\'t even scream out. Her voice just wouldn\'t leave her 

"A..Arie-" 

But despite that all which was at her mind at the moment was Ariel. Ariel\'s situation was much worse as she was on her back, Serena could tell, the dagger hadn\'t only pierced her but also Ariel. 

Anger began to cloud Serena\'s mind as she slowly moved her hand towards her wound. As this happened, golden butterflies could be seen forming in the air as a golden flame engulfed the dagger and wound. 

"Sorry." 

*Boom* 

But right before the flames could fully spread through Serena\'s body, and before she could initiate her attack. Dark Flames erupted from the tip of the dagger as it sent out a small explosive fiery outburst from it. 

Not only did it burn Serena\'s wound but it the pain was so strong that she lost the ability to think straight. Her consciousness began to fade. 

As this happened, she slowly stretched out her hand to the figure of John who happened to be the last thing she could see. And as she did, she was able to see the hopeless expression of despair on his face. 

His eyes widened and his mouth trembling as he dared to speak out the words. 

"S-Serena...? Ariel...?" 

"I...Idiot... S...Sorry..." She muttered with her little remaining strength. 

"A.....Ah-AAAAAAAHHHHHHHHHHHHH!!!!!!" John screamed out in rage
