Kamado Blood! Fury at 100%

*THIRD PERSON*

Alyx fell to his knees, tears started to stream down his face. The Super Quirks were closing in on them.

"Kid, come on, get up!" Hawks shouted.

"What will it be, Leonidus?" The President asked.

Alyx stayed quiet, then, red and black smoke came off of his body. Wind started to circle around the room, the door leading into the room flew open and more wind whirled around the facility.

"Is there a draft in here or...?" Hawks started to speak until he noticed Alyx.

The winds grew fierce, and the smoke emanating around Alyx increased around his body. Mt. Lady and Hawks stared on as Alyx slowly rose to his feet. The President turned and looked at Leonidus' Mother, who was smirking.

"What is he doing? What is this?!" She demanded an answer.

Leonidus' Mother spat blood at her, "You've made him maaad..."

The President quickly turned around; the wind had blown out nearly every light in the room. Alyx's tears turned into red smoke.

In a voice as still as water, Alyx spoke, "I will not... Spare you any mercy."

The entire room shook, a horn burst out of Alyx's upper left forehead. Four crimson red arms burst out of his back. His body contorted and twitched; his scar grew larger over his face. Mt. Lady and Hawks stood back and watched; they couldn't believe their eyes! Unbeknownst to them, Alyx had accessed a deeper level of his bloodline, a level beyond mental return! The President looked on in fear as Alyx took on a gruesome form!

"H-He is... He really is related to that demon!" She thought.

"Hurt... Them... KILL YOU!!!" Alyx screeched.

Alyx had finally snapped, he was truly angry, and everyone in the room felt his intensity! Back in the Seventh Plane, Nezuko watched as Alyx entered this state of anger.

"Tanjiro, this isn't good! He's... He's using Demon Transformation with his Rage Quirk!" Nezuko exclaimed.

Back in the facility, Hawks and Mt. Lady looked mortified, they never seen such a Quirk in action before! Alyx was twitching rapidly, his mind and spirit were all but gone. Alyx let out a high-pitched roar that shook the facility! He took off after the President on all fours, like a feral hound. One of their Super Quirk creations stepped out in front of him. Alyx growled and slashed at the creation with his shadow hands.

"We're coming, Leonidus!" Mt. Lady shouted.

Alyx turned around, and as Mt. Lady & Hawks ran towards him, he smacked them backwards. The President took this time to climb out of a hatch, she made her way to the surface and rushed to a car. Alyx followed her up the hatch, jumping up and bursting through the hatch door. The car the President was in took off and Alyx pursued her! Deku and the others arrived on the scene. Hawks and Mt. Lady emerged from facility with Liz and Marie.

"Deku, Creati, Red Riot, Uravity, with me! We don't have much time!" Hawks shouted as he flew off towards Alyx's direction.

Without hesitating, they followed Hawks, the rest of the class watched on as they ran down the street.

"What's going on?" Kaminari asked.

"Aly... He... He's a monster! A scary one! He's gonna kill that mean lady!" Liz exclaimed.

Everyone was shocked, what caused this? Just then, a figure appeared out from behind a wall, dressed in a pink and white kimono.

"Take me to him, please!" Nezuko shouted.

"W-Who are-" Mina tried to ask.

"We don't have time for questions, are you wanting him to go on a rabid killing spree?" Nezuko interrupted.

Everyone looked at each other before returning their eyes back to Nezuko. They nodded at her and hauled ass down the street, following Hawks and the others.

"Hawks! What's happening?!" Deku shouted up to him.

Hawks pointed down to a car, "That's what! He's completely snapped!"

Alyx was ripping and tearing through the roof of the President's car. She swerved left and right, trying to knock him off of the roof. Alyx crashed his head down through the car roof, and bit the neck of an HPSC Officer! The officer was pulled out of the car and torn in half by Leonidus! He tore the roof of the car off, which caused the car to roll over three times! Hawks, Momo, Deku, Uraraka, and Kirishima stopped a few feet away from the accident. The President crawled out from the smoking car, bloody and bruised. She somehow managed to survive! But, Alyx tore through the car, and rushed over to her. He pounced on her and was about to strike until Momo called his name.

"Alyx, please! Stop!" Momo shouted.

Alyx looked over at Momo and the others. He tossed the President aside and stared at them. They slowly approached him, Alyx started growling, and he flared his teeth. The veins on his forehead became prominent as he got angrier.

"Hey, it's alright, it's us!" Deku cheerfully reassured.

Alyx lunged towards them, but before he made contact with them, Nezuko flew in and kicked him in the face! Alyx slid backwards and looked back up at Nezuko.

"W-Who...?" Hawks questioned.

"A relative. Let me handle this." Nezuko responded.

Nezuko had manifested out of the Seventh Plane! She only had 10 minutes before she was transported back there.

"Alyx, listen to me! Control it! I know it's hard, but you can't let it take control of you!" Nezuko yelled.

Alyx screeched and ran towards Nezuko. Alyx's shadow hands fully wrapped themselves around his arms. He slammed the ground in front of Nezuko, which shot her up into the sky. Nezuko kicked a huge chunk of debris straight into Leonidus! Momo jumped into action, she created a staff and sent Alyx flying back! She charged towards him but Alyx quickly rebounded! He tackled her down to the ground and he bit down on her staff. He pushed down, trying to get at Momo's neck, while Momo was pushing against him!

(Immersive Read Point: Listen to Mewsic's cover of "Nezuko's Theme"!)

Deku used his Blackwhip to try and pull Alyx off of Yaoyorozu, but it wasn't working! He had a firm stance on the ground. Kirishima and Uraraka both grabbed onto Deku's Blackwhip and pulled with him. Hawks helped Momo out by pushing up on her staff. Nezuko jumped on Alyx's back and tried to pry him off of Momo.

"A-Alyx, please! Stop!" Momo begged through her tears.

"Remember who you are, Alyx! Remember your family!" Nezuko shouted.

Alyx's eyes widened, he blinked and was standing in a place completely white. In brief flashes, he saw his childhood friends, they were playing on a playground. Smiling, laughing, and even hugging. His mother and father walking with him, he saw Momo and the others. Voices from his past flooded his memory. A hand touched his shoulder, he turned around and saw Momo. An almost angelic aura surrounded her.

"It's alright, my love. It's alright." Momo cooed.

She embraced him, Alyx's eyes widened, and he let out a shaky breath.

"Mo... Mo..." Alyx muttered as he started to tear up.

The vision of Momo faded into a swarm of beautiful gold & white butterflies. Alyx turned around and faced his grandfather, who welcomed him with a warm smile and open arms. Alyx stumbled forward, ignoring the feeling of anger and savageness. Tanjiro disappeared, and in his place, stood Alyx's father. Alyx looked in awe as more tears streamed down his face. Almost as if he broke out of his shell, Alyx seemingly returned to normal! He hugged his father tightly, burying his face in his chest. His father smiled and patted his son's head. Alyx opened his eyes and stared at Momo. Tears filled his eyes and fell down his face. Momo silently gasped as she realized he was finally back! Alyx burst out of their grasps and Deku's Blackwhip.

"That's right! Kill them!" The President shouted with glee.

Her voice echoed in Alyx's head. He stood in front of Momo and looked down at her. He quickly dropped down to her. Momo closed her eyes, thinking he was going to attack her, but to her surprise, he instead hugged her head.

"I... Sorry... Love..." Alyx muttered.

The rest of the class and Mt. Lady arrived on the scene. They stood back as they saw Alyx holding onto Momo. Alyx looked up and faced the others, realization and his memories finally hit him.

"Leo... nidus... Fa... Ma... Lee..." Alyx whispered.

Nezuko's words and the efforts from Tanjiro and Darren worked! Alyx let go of Momo and stood up. He faced the President, who had a huge Super Quirk creation walking towards her. Leonidus finally snapped back into reality!

"Wake... Up... Mode... Three!" Alyx shouted.

*LEONIDUS' P.O.V.*

I felt the rush of my Overdrive hit me, which woke me up. I don't know what happened, but everything was in disarray! I felt my head and touched... A horn?! My Rage Quirk was active too, I must've gotten pissed and blacked out! My right arm had three spikes jutting out as well! I watched as this hulking abomination picked up that President chick, and it absorbed her?!

"Now, I can finally eliminate you, Leonidus!" She roared.

I looked down at my arms, I think I'm finally understanding how my Rage Quirk works! As long as I kept myself from pushing my anger too far, I can control it! All I need... Is just one full power shot straight into that bitch's head!

"Overdrive: Full Control!" I shouted.

My Rage and Overdrive aura ignited and exploded outwards!

"Do you really think you have enough power to stop me? Don't make me laugh!" She scoffed.

She swung her fist at me, which I narrowly dodged! I took a deep breath in and then back out. Grandpa Tanjiro told me about all of the breathing styles, Sun Breathing was the most powerful, which is what I'm gonna have to do!

"Sun Breathing: First Form, Phoenix Dance!!" I roared.

A bright, fiery Phoenix burst out from the flames created by my breathing technique. It rammed right into that giant's face! In a matter of seconds, I went right through her head! She collapsed to the ground and dissolved. What in the hell were they making those Super Quirk freaks out of? I landed hard on the ground, the horn on my head wasn't there anymore, but there was quite a bit of blood around that spot. Those things on my arm weren't there anymore either. Everyone rushed over to me.

"Holy fuck! What was that?!" Kaminari shouted.

"He accidentally accessed his Blood Demon Art and Demon State. That's why he acted so feral and savagely. Don't worry, he only can do it, none of you can." Nezuko explained.

"Blood Demon Art? All of that's real?" Tokoyami questioned.

"Yes, I used to be a demon, actually. I obtained those abilities after surviving an attack. How he's able to use it, I'm not quite sure." Nezuko replied.

"Oh, right. I almost forgot what Ms. Shinobu told me." I said to myself.

"Woah, what? First off, who even are you?" Jiro asked.

Nezuko turned and face everyone, "I am Nezuko Agatsuma. I'm Alyx's Great Aunt. Or, well, in his grandfather's words, Great-Great-Great-Great-Great-Great-Great-Great-Great-Great Aunt. I assume he's told you about Tanjiro, yes?"

Everyone sat there and tried to process what was going on. I got back up and walked over to Nezuko.

"How are you even here, Aunt Nezuko? Not to mention, how can anyone besides Deku and Tokoyami see you?" I questioned.

"Oh! I'm simply projecting myself from the Seventh Plane, it's quite simple honestly!" She responded.

Nezuko soon returned back to the Seventh Plane. My head was pounding, plus my lungs were on fire! And again, we cleaned up the area, I looked at an overturned car that was ripped in half!

"Holy hell, who did that?" I asked.

Hawks and Mt. Lady looked at me, their eyes narrowed and mouths agape.

"You did, Alyx." Hawks told me.

"Woah? Really? Cool!" I shouted.

[Later That Night...]

Momo ran her fingers through my hair as we laid in her bed, I held my hands up in front of my face, I noticed that I had claws!

"Woah, holy shit! I guess I still haven't kicked my Demon Transformation." I showed Momo my hands.

Momo shook her and smiled, "You're making me jealous, Alyx. I wish I could have nails like that."

I laughed at her sarcasm, "Well, if you'd like to become a demon for about 20 minutes, feel free!"

I was already super excited to see what I'd do at Mt. Lady's agency tomorrow! Momo and I fell asleep rather quickly, I guess we both were exhausted after what all happened today.
