My Slayer System: Rise to Supremacy

"Aren't you… aren't you the heir to the Thunderbolt guild? Harry?" Jay asked in shock as he could see a young man standing with his body crackling with yellow lightning with a frown and a smile on his face.

"I couldn't sit back at home when the world is in trouble with a former lowerclassman of mine trying to kill his friends." Harry smirked as he titled his head towards Jack who growled in anger and then proceeded to shoot a long stream of dual laser beams towards Harry.

"Oh Jack!" Harry muttered as he swung his sword that was now being surrounded by yellow electrical Ki in a precise arc smashing the laser beams away from him and into the ground beside him burning a deep hole in it.

"Go!" Jay roared as he blitzed forward, his hands breaking down and taking the shape of a canon and with a grunt, an explosion shot forward as two energies swirled towards Jack who quickly zipped away causing the energies to crash into the ground and ripped a deep crater in it.

"AWOO!" Jack howled as he bolted for Jay who was trying to reposition himself when Gray suddenly appeared in front of them, intercepting Jack with a solid punch to his snout sending the omega werewolf skidding an inch in pain.

"Humanity trusted you all, Jake trusted you all. And you betrayed us?" Gray shouted as he punched his knuckles together, his Qi swirling around his feet and without wasting time, he dashed forward.

"I'm not done with you!" Gray roared as he snapped his fist towards Jack's face but without breaking a sweat, Jack clasped his hands around the fist bringing Gray's hands to a halt.

"Ywo nweed two dwie!" Jack howled as he hurled his claw fist towards Gray's face but in an instant, Jay dashed forward with all the speed he could muster as his hands morphed into a black shield which he placed in front of Jack's fist.

Bang!

Boom!

The shield rang out as Jack's fist slammed into the shield with a reverberating bang that caused Jay's hands to throb in pain.

"Pwest!" Jack howled as he slammed his foot into Jay's chest sending him hurling with blood spraying from his mouth before he lifted Gray with a single hand and tried to slam him into the ground but like a lightning bolt, Harry zipped forward with his sword raised above his head, lightning Qi crackling around it and was about to slam the sword into the werewolf's arms but…

Buzz!

Two laser beams shot towards Harry with immense speed that he had to quickly snap his sword in front of him in an attempt to block the beam but…

Bang!

The force of the beam and the fact that it was fired at point blank range, caused Harry to go flying and spinning back and in order to stop himself, he slammed his sword into the ground, causing it to slice through the ground like a knife cutting through butter.

And that was when he finally came to a skidding halt, his knuckles smoldered slightly due to part of the laser grazing it.

"All of you need to die for father's plan to be realized!" Jack howled as he reverted his face to human form and then glared at Gray in his hands who was thrashing around.

"Starting with you!" Jack hissed as he proceeded to lift Gray above his head and was about to slam him into the ground when…

Zoom!

The sounds of sharp blades slicing through the air was heard causing Jack to swiftly turn around to see fifty Qi swords heading towards him at full speed.

In one fluid motion, he hurled Gray away causing him to tumble a few times on the ground before he swiftly turned around with his furry arms crossed in an X shape above his head as the swords struck with a deafening boom, black blood trickled down Jack's hands as he grit his fangs and was being pushed back slightly, causing deep fissures to run across the ground.

Finally, the swords dissipated and Jack huffed and puffed as he tried to place his hands down when he saw Jay in front of him with a smirk on his face and his hands transformed into mechanical giant fists.

"Have a taste of your own medicine." Jay hissed as he swung his mechanical fists forward causing them to slam straight into Jack's face and therefore hurl him across the battlefield with a broken tooth and blood spraying from his mouth.

He came to a skidding halt and was about getting up when he saw Jay appear in front of him after boosting his speed using his transformed legs and then unleashed a powerful uppercut with his mechanical hands again causing Jack to get lifted off the ground a bit.

But before he could go flying, Gray quickly whipped his hands around and a Qi whip shot forward grabbing Jack's legs and then with a heavy tug, Jack was sent crashing back down with a deafening boom as the ground quaked loudly, a deep crater formed beneath his body and dust along with debris were kicked up.

"AWHOOO!" Jack howled again and from the dust that obscured the view, four laser beams shot towards Jay who didn't expect it and at the last moment, he tried to transform his hands into a shield as the beams approached rapidly.

The beams were mere inches away when he finally got his shield out and right on cue, the beams slammed into it, sliced through the shield and the force of the beams also sent Jay hurling back.

And just in time as Gray launched forward with Qi swirling around his feet and fist which he swung towards Jack's face but the werewolf quickly leapt back and then whipped his legs out slamming it straight into Gray's face and also slamming him into the ground.

'Damn it! My Qi. Is all gone.' Gray thought as he struggled to stand up when he saw Jack lift his furry foot and was sending it hurling towards Gray's head.

'Is that it? Is this the end? Is this how I really die? Is this how I will die without seeing the end of this war? Damn it! I'm sorry Jake, I failed you.' Gray thought in disdain as the foot rapidly approached him when he heard…

"Thunderbolt Technique: Fifth form!" Harry said, his sword in its sheath as it was glowing soft yellow from the outside, the crackling lightning around Harry intensifying and then…

"Spark of a thunderstorm." Harry muttered and then he disappeared.

Looking he teleported as he suddenly blinked in front of Jack who was unable to react quickly and then his foot got sliced off.

"Arghhh! AWOOOH!" Jack howled as he tried to steady his footing when…

"I'm sorry dear friend. I hope you rest well and get reborn as a human with good parents." Harry muttered as he suddenly blinked again then he appeared behind Jack who could be swaying left and right before slumping to the ground in a thud, his head decapitated, blood gushing out of his neck like a fountain.
