Karna watched as the two demons began to come towards him not speaking anything. They appeared as if they are mindless beings that only targets destruction.
'Looks like the flute like demon was the consciousness, I guess. So, one demon uses music, the other uses the wind as the source of medium and the last injects the aspect of death into it. All combined form the music that kills anyone who listens to it. But now sensing their aura's I can say that they are not that strong. Ability wise they are but when it comes to the matter of power
They are weak
So, a wizard using his magic as a cover around their body might prevent the effects, but they need to be strong as a higher A rank wizard"
Karna began to speculate every aspect of the demons he was about to face. The demon with the element of death was killing every plant life that he was steeping on the ground and the one with the wind element seemed to be charging up for wind strikes.
"alright here goes" Karna said as he readied his bow. He knew he can defeat them easily, but the target is making sure they stay down till he can adapt to their powers.
The wind demon threw fast wind slashes at him. But as he dodged Karna had only one thought in his mind.
'slow' with his more than average perception combined with the dynamic vision of the sharingan allowed him to easily see the trajectory as well as the attacks themselves easily and was able to calculate the amount of power in them. Seeing that he can handle it, he made the bow disappear and activated his slayer magic and tried to absorb the attack into himself.
"ouch" the pain was not that much but the curse energy itself began to cause a bit of sting in him.
Magic was an energy that is created by the power of emotions within a person and is used by the said person. But the fact about cursed magic is that it is the amalgamation of negative emotions creating power that is not created within the curse user itself but from others that surround him. Magic comes from the being itself while curse is taken from other beings.
There are methods to take ethernano from the atmosphere directly while in battle. But taking it from others is an entirely different concept as each person has an entirely different signature. And if he is right the curse energy expelled by a person has no direct relation to magic other than being derived from emotions. So, if his calculations are right, the cursed energy from others at first is filled with different signatures while the demons are able to absorb them and turn it into their own form of curse which is same for all demons.
Demons are not naturally born, and all are created artificially by Zeref so the signatures of curse energy being same makes sense. And the humans who are made into demons must also have the same. But looking back Karna made another theory. What if the energy released by others is different but the curse energy itself is same. Not because Zeref created all demons but because the property of cursed energy is that its uniform after being converted.
If this Karna's theory was correct, as long as he absorbs the cursed energy, he will get the ability to convert the energy released by others during their negative emotions into cursed energy. making his battle with pissed off and assholes easier.
He managed to absorb the cursed energy within the wind. He can feel his slayer magic trying its best to adapt to the cursed energy. He was feeling pain that was increasing little by little. But when he looked at the demons again, he saw something that he did not expect.
He spread out his senses to where his friends were dealing with the flute demon and found out that the demon seem to be in a very bad shape.
'looks like that made them speed up'
As Karna watched, the wind demon and death demon combined quickly in front of him
'death with wind huh, absorbing curse energy and death energy became many times harder now. But hey those guys did not even take 5 minutes to make that demon this weak. Looks like I have to make this more quickly if I don't want to lose my image.
As he looked, he saw the demon make more powered wind strike and this time it seems like the death aspect is mixed into it as well.
Karna winced 'damn it, it became more harder to absorb now' but he knew what he needed to do. He felt the sting of the cursed energy he had absorbed before but when the next strike was thrown by the demon, he activated his sharingan at full power as everything slowed down.
As soon as the demon threw the big ball of swirling death wind, Karna materialised his bow and brought out an arrow he never had the chance to use before. The Nagastra, the arrow capable of paralysing any sentient being.
As the arrow hit the demon essentially paralysing it, Karna made sure to absorb the entire attack thrown by the demon. He felt the death energy as well as the curse energy trying to kill him as his magic tried its best to absorb and adapt to both.
He took mana potions from his inventory and began to chug them one by one, thereby increasing his magical level as much as he can. The demon at the time was trying its best to move but the paralysing effect of the arrow seems to be holding it down easily.
Karna could feel the curse and death energy trying to overpower him right now.
'not now, I still got a lot left to do goddamn it. This is just the beginning'
"AAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"
Suddenly the energy within Karna calmed down. And he became silent.
He closed his eyes and if people looked at him right now, they will see that he looks to be monotonous, almost dead looking.
Suddenly patterns began to spread around his body, they seemed to represent runes that seemed to be focused on the essence of death and negativity. Karna opened his eyes and looked at his body.
'looks like I got a new transformation. Let's call it DEATH DEMON SLAYER FORM'
He looked at the demon squirming while in paralysis. He materialised his bow and began to channel his magic through an arrow.
The colour of the arrow changed to deep violet with black coloured sparks spreading out of it. Karna gently released the string at the demon.
As soon as the demon got hit with the arrow, it stopped moving and suddenly it got covered with a black colour from head to toe and it turned into powder which disappeared almost immediately.
Karna then released the form as he sensed his friends coming to his location quickly.
"well looks like I gained a lot today" he said with a smile while looking at his friends running towards him.
At the time in Tartaros
A book in the library suddenly turned into powder.
Mard Geer deep within the building turned suddenly.
'a demon vanished. But how, is it END"
In another deep forest
"a demon of my creation has disappeared"
A black wizard walking aimlessly suddenly stopped and looked towards a direction. His eyes devoid of any life seemed to have a spark of hope which immediately disappeared in the darkness. And he kept on walking.
