A Certain Unexplainable Dragon Slayer

Move Point

Y/n was in his dorm room with his 2 roommates. One of which was a necromancer named Esther Rosenthal the other is the library of 103,000 grimores Index Librorum Phuibitorm. While Y/n was on his bed reading some manga both Esther and index watching T.V. They were watching the news or more specifically the weather. Y/n couldn't care less about the Weather People since they always get it wrong, apparently they used to always get it right but that was when Tree Diagram existed.

Y/n unfortunately never got to experience that since the day before his memories were wiped Tree Diagram was apparently destroyed. He couldn't help but wonder if he had anything to do with it but it didn't matter to him. Either way right now the weather here is as unpredictable as everywhere else in the world.

'The Daihasei festival is coming up, I should start training.' Y/n thought. He Got up from his bed and started to walk to the door. "Be back later..." Y/n says to his 2 roommates and walked out the door. The 2 gave him a soft wave before he shut the door.

Y/n breathed a sigh before squatting slightly and then shooting up in the air like a rocket, now in the air, Y/n felt the wind push against his skin a couldn't help but feel slightly relaxed at the feeling. However, it passed when he felt his toes touch a buildings edge. He jumped once again, repeating the process, jumping from building to building until he reached his destination. It was a flat little land and far away from civilians so no one would get hurt.

'I most likely won't need to use them for the Daihasei Festival, not like I would even if I needed to, but I should figure out what's up with those white wings.' Y/n thought to himself.

The first time he used the white wings was during the Level 6 disaster, but he didn't even know what they were. In fact he didn't even know they were behind him. Esther was the one that pointed them out to him, he tried to ask Accelerator but he didn't see them either and apparently he had black wings on his back. Which Y/n also didn't see. 

The second time  was with Agnese, Y/n still had no clue they were there, all he did was use his negation power.

The only theory he had was that it was part of his Negation Dragon Slayer. After all, the first time his negation took a form was in the battle against Issac. And the same with the battle with Agnese, it usually was just a body part he had to choose at the time, to put the negation in.

But both times black energy-like substances surrounded his hand. Maybe this was a sign he was getting stronger? 

Who knows. Either way the white wings were a mystery and why Accelerator had black ones are just as much. But both times he felt rage bottled up inside him when he used it so he wanted to make sure he was able to control it. After all he got a major boost in power while using them. if he could control it, he could probably use his negation more effectively then just a couple of seconds on a certain body part.

"Alright time to test this out!" Y/n said and then a black aura surrounded him "Negation Dragon mode!" Y/n said and tried to power up a bit more, however, nothing felt... different. He then looked behind him and to his surprise there were 2 white tornado-like wings on his back. "Whoa." Was all he could say. He moved them around a little trying to get a feel for them until he thought he had some control over them 'Here goes nothing.'

Y/n brought a wing back and then hurled it at a boulder. Even Y/n's skilled and enhanced eyes couldn't keep up with the attack as the wing shot forward causing a slightly big explosion to occur where the boulder was. The wing came back and all that was left was a big pile of rubble. Y/n then decided to use them a little more and started destroying a bunch of the landscape.

'Time for the final test after all these are wings.' He thought while smiling to himself, he then focused a little bit more and to his surprise he actually started to get lifted off the ground 'This is amazing whenever I flew before it was thanks to my flames or wind propelling me by my feet.' Y/n thought he then flew up into the air to the point where he was at the level of a tall building 'I don't feel too much energy being drained either, this is awesome.' Y/n then got an idea and let his white wings disappear and he started falling to the ground. Y/n closed his eyes, he could sense the ground closing in on him. He smirked.
