A Spark (Aizawa x reader)

One of the Nine Demon Kings

"Alright then you ugly bastards, who's first?!" Rin yelled.

He stepped out of the circle and you shook your head with a smile.

"Don't get your tail pulled Rin." You smirked.

"Shut up!" He pouted.

Snickering, you ran your fingers along your blade then readied it, turning to Rin.

"Ready?"

"Ready." He nodded.

You turned back to the circle, Aizawa was just standing up, and you sent him a weak smile before turning to Yukio who was holding the phone in his hand.

"Anything?"

"Not picking up."

"Damn, looks like we'll have to do this ourselves Rin, Yukio."

Yukio pulled out his guns and stepped out of the circle.

"Like hell you are!" Bon yelled.

Bon stepped out of the circle a little to the left.

"Damn it Bon!" Shima whinned.

The Shima, a little to the left of him.

"Guys..." Konekomaru mumbled.

Then Konekomaru, who was silently followed by Izumo.

"I have to to help!" Shiemi nodded.

She filled the last gap, the circle was covered by exorcists. You grinned and huffed out a sort laugh shaking your head.

"You're all reckless."

"What does that make you?" Bon smirked.

"Insane. Let's do this. Exorcists, Mission, PROTECT CLASS 1-A!" You yelled.

"YES MISS!"

Everyone got to work, Rin drew his sword, his body becoming surrounded by Blue flames as he charged.

"The flames..." Uraraka whispered.

Gulping, you swallowed your emotions and ran head on into the battle. Slicing any lower level demon you could find. When most of them were down, you brought your attention to the higher ranked demons who prowled the edge of the circle, just waiting to attack.

"Leave them alone!" Rin roared.

He jumped and brought his sword down, only to get swiped away by the hounds paw. You clenched your jaw and went to attack but you were froze on the spot when Aizawa stepped out the circle, your heart dropped.

"NO!" You yelled.

He tried to attack but the demon pinned him down to the ground easy. Midoriya went to step out as did Hizashi but they were stopped instantly. Hizashi tried to use his quirk but it had no affect on the demon.

"Stay in the circle!" Yukio shouted.

"We can help!" Todaroki argued.

"Not against demons of this level you can't, only a demon king would be able to kill them."

"A demon king..." you whispered.

The was clapping and you tensed up.

"You want to save him, how very touching~" a taunting voice rang.

Your blood ran cold, your eyes stayed focused on Aizawa as you said nothing. You could see the crimson running from his body as the beast claws held him.

"Won't save him? Fine."

The figure emerged from the trees on the other side, his dark cloak hiding his face, but you didn't need to see it.

"Kill him." The man ordered.

The hound raised a paw, and before you realised what you'd done, you ran, in the blink of an eye you were stood over Aizawa, the demon hound exploding into a mass of black.

Blue flames danced around your body and sword, the horns on your head stood tall, your beanie landed on the ground showing your pointed ears, tail swaying slowly, and if course, the blue flaming crown over your head.

"You can hurt me... beat me... kill me even... but don't you DARE LAY A HAND ON HIM OR ANY OF THEM YOU SON OF A BITCH!"

Turning to the man, You snarled baring your sharp teeth, raising your sword you stood protectively over Aizawa. You couldn't bring yourself to meet his gaze.

"(Y/N) no..." Yukio whispered.

"You've come along way since being a child, I knew you were a demon of course but only one demon has blue flames as bright as those."

Stabbing your sword into the ground, you knelt down and nudged Aizawa towards the circle.

"Stay in the circle..." you whispered.

Picking up up with ease, your blue flames surrounded him as you handed him over to a bleeding Yukio who helped steady the pro hero on his feet. Your flames leaving his body when you let go, you looked away ashamed.

"Treat his wounds Yukio... please..."

"Of course..." Yukio replied gently.

No one else said anything, they were all in shock at seeing you covered in blue flames, the same blue flames Rin had.

"Who are you?" The man called.

"You know who I am." You hissed picking up
Your sword.

The man cackled and lowered his hood, letting you see his scared face.

"Of course I do, but they don't. Go on, tell them who you really are demon. You monster."

Taking a deep breath, you closed your eyes letting a few tears slip out.

"I am (Y/N) (L/N), one of the nine Demon kings. Demon queen of Earth, along with my brother Amiamon, daughter of Satan."
