"Think of it as a large maze which only you know the way around, and you lead the enemy inside and use that advantage to beat them no matter how strong they are"
"I don't get it"
"Hmmm, a domain is like a covered space that the caster controls. It is made with crystalline karma and used to cover the opponent in a space where the caster controls and it takes a massive amount of karma."
"If it takes too much then why do the supernatural use it?"
"Well,.. There is almost no supernatural that could use a domain, but upper-class demons have no problem using it. It gives them a huge advantage over the opponent and sometimes, a guaranteed victory"
"I don't think this is important" Kakashi pressed the play button on the remote.
"Once trapped in a domain, there's no way out. You can't burst out and in the two worst-case scenarios, it might have some negative effects on you"
"There must be a way to counter it, right?"
"Well, there are two options. Firstly, activating a karma shield, that way you won't be affected by the domain or secondly, waiting for someone with a higher karma capacity than the caster"
"But if I activate a karma shield would I be open to physical attacks and what if there was no one around"
"Then you just have to be faster and dispatch the demon before the domain is fully activated"
# END OF FLASHBACK
"That's it!, I just have to be faster and kill you before your domain fully activates!" Kakashi yelled running with a greater speed.
As Kakashi approaches Tomura he tries to charge his karma the his fist. _No, takes too much karma_ Kakashi gathered his lightning blast on his fist and tightened it, he was sure Tomura hadn't killed Kurumi yet. If he uses his lightning blast, he might also kill Kurumi too.
"Lightning punch!!!"
Kakashi yelled as he landed an unexpected hit on Tomura's stomach and made him spit up Kurumi, and Kakashi caught her in his hand. Tomura rolled up the floor before landing at the other end of the arena.
Tomura started vomiting blood as Kakashi walked to him slowly, the right side of his hair was completely black.
Kakashi bursted out with laughter, his malevolent voice made it more unsettling for Tomura.
"I did it!" He bursted out. "I'm finally back!. Get ready for me, ...huh?"
Kakashi tilted his head, facing Tomura - who was shaking.
"It's you again?"
Tomura stood up and staggered a bit before standing completely on his feet.
_The demon is currently in control of his body, I just have to stress him till Kakashi takes over again_
"Looks like you still want to fight?" The demon asked. "I don't have your time. So, I'll finish you up"
"This is the demon!" Tomura said under his breath. The force of the karma that he released was enough to make Tomura choke, the air was becoming too heavy for him to breathe. "St... Stay away from me!"
Tomura yelled but he didn't listen, each step he took made him look more intimidating. Tomura could sense nothing but murderous intents coming from him.
Tomura vomited another batch of transfigured humans which he had stored but when he tried to use his technique, he kept on vomiting blood.
_Damn it, I've wasted too much karma_
"I said stay away from me or else!..." Tomura tried to cover his fear but he was cut short as he vomited blood again. _What d... what did he just do to me_
"Or else what?" The voice sounded more muscular and more intimidating, he spoke each word with superior authority. "I didn't give you permission to speak"
Tomura froze, and he felt a sharp pain in his left arm. "Arghhh!!!" Tomura turned to notice that his arm had been severed from his body. _How?, How did he do that? I didn't sense any form of karma. It hurt, it hurts so much. I can't stop myself from bleeding._
"Come on," the demon that had taken over Kakashi's body said. "Stand up and fight. The fun just started"
Tomura shook his head vigorously and pushed himself backward with his feet. His eyes were filled with tears, his entire body was shivering and covered with sweat as he let out a yelp for help even though he knew no one was coming to his rescue.
_I can't die now, there was so much I haven't done yet. I don't want to die_
"How pathetic can you be? You are nothing but a disgrace to your clan and all demons out there" The demon stopped for a moment and squats in front of Tomura. "You call yourself a demon, but yet, you meet another demon and all you can do is cry"
"I... I'm... I'm sorry, please forgive me!" Tomura kneeled and bowed his head to the ground. "I'll not do it again. So, please forgive me!"
The demon leaned his head slightly to the right and rested it on his arm. He stood up and looked at Tomura, disgusted.
"Worthless maggots like you are not meant to be called demons. People like you are the reason why demons are looked down upon" He turned his back to Tomura. "I'll just let you go today because this isn't your real body, so torturing you would be a waste of time. But there won't be a next time"
Tomura's body exploded as soon as the demon stopped talking.
"Now, let's see how much fun I can have" The demon said with a mischievous smile on his face.
"I'm sorry, but I can't let you do that" Someone spoke up from behind him.
The demon turned to the person and saw him himself standing face to face with Yaze.
"And who are you?"
"The boy's body you're in right now is one of my students, and I can't let you use his body like that" Yaze said without an expression on his face.
"You sure have the guts to challenge me?" The demon laughed. "So tell me, what's your name?"
"It's doesn't matter" Yaze said and adjusted his headset on his head. "But, since you asked so nicely. I'm Yaze Hitonomi, and I know you're Kenshin, the demon king"
"I..." Kenshin was about to speak but Yaze punched him, sending him backwards for a few meters before he finally landed on his feet.
"I'm here to fight, not talk"
Kenshin smiled and clothed his fists with karma. "You're speaking my language!"
In a flash, Kenshin darted towards Yaze and launched himself to the air and landed with an attack from above. Yaze dodged the attack as Kenshin landed in front of him, he kicked the demon, sending him rolling till he used his arm and pushed himself to the air and landed on his feet.
"You have Kakashi athletic build, and also his speed" Yaze complimented. "But, you can't defeat me at your current state"
"Shut up!" Kenshin yelled and launched himself towards Yaze again, as soon as he was about to attack.
"Just give up" Yaze said. Kenshin tried to stop himself but it was already too late, Yaze was standing behind him.
Yaze caught his shirt and threw him against the wall.
The demon suddenly coughed out blood, he covered his mouth and coughed out more blood before looking at his hand.
"It's not even five minutes yet" he smiled. "Damn you, brat"
Ayaka came running to the scene. Yaze was not there.
"Kakashi, are you okay?" She asked as she hugged him. "I sense a sudden burst of dark karma, a very powerful one"
_She must have sensed the domain_ Kakashi thought, he didn't know what happened but he was glad it was now over.
"The demon opened his domain"
"A demon powerful enough to use domain expansion, we should report to Yaze-sensei"
Ayaka seemed scared although her voice was calm.
"Don't worry, I took care of it...." Kakashi suddenly coughed out blood. He looked at the blood on his palm. _This feeling?, Just like that time at the lab_
"Are you okay?" Ayaka helped Kakashi to sit on the ground. "Don't move, I'll heal you"
"Don't worry about me. Heal the kid first" He said pointing at the boy who was said to be the flame sage.
Ayaka nodded and ran to the boy, Kakashi stood up and walked after her.
"Ouch!" The wound on his knee hurt, but it didn't stop him. He continued, hopping with one leg and dragging the other one behind him.
"I did it again"
