...And the Rise of REAL Heroes! This is... One For All!!

I woke up on my back, and saw nothing but white. The ground I was laying on was flat and cold. I looked down at my right arm, it was there now! I slowly got up and noticed a man floating in the air, or was he sitting on something?

"H-Hello? Who are you?" I asked.

"Ah, Leonidus, you're awake. I was wondering when you'd wake up. I am Ubuyashiki Kagaya, 97th leader of the Demon Slayer Corps." He announced.

"S-So, you're like the leader of the Hashira?" I slowly stood back up on my feet.

"Indeed, that's correct." Ubuyashiki nodded.

"Am I... Dead?" I questioned.

Ubuyashiki chuckled and shook his head, "Not necessarily, allow me to explain."

Two portal doors opened up on each side of him. He lifted his right hand.

"On your left, you'll pass on into a new life. Your memories will be erased, and you'll be born with a new soul and body. Whoever you are and wherever you end up will be dependent on fate itself." He explained.

Ubuyashiki lifted his left hand, "On your right, a chance to begin again. We are allowing you one chance to correct your mistake. You'll be back where you were just a few seconds before Izuku Midoriya attacked All For One. Whichever you choose, may the god's guide you to glory."

I stood there and looked at each portal, my mind was already made up. I walked to my right and looked at the portal.

"Okay... Just a few seconds... That's all I need!" I said to myself.

I activated both Mode Three and Boost Fire. I ran through the portal and the rush of air hit my face. I saw Deku begin to jump up towards All For One.

"THEN GIVE UP!" I heard him say again.

Right before he made contact with All For One, I quickly rammed my fist directly into All For One's face. All For One went crashing into the ground, and my arm was steaming!

"A-Alyx?" Deku could tell that the look on my face was different.

After everything I just witnessed, I couldn't let it happen again! All For One got up and brushed himself off. I stayed in the air and looked down at All For One.

"I'm not letting you do that... Not again!" I shouted.

All For One looked confused, "Oh? What might you be talking about?"

All For One melted, it was another one of those body doubles! We looked up and saw him, he ran down those claws at us! One of them pierced my left shoulder, rendering my entire left arm useless! I grabbed Deku and threw him away from the attack. I fired off my Stardust Shoot.

"S-Stardust Shoot: Five Fingers!" I fired off and broke through some of those claws!

Momo created a huge barrier that shielded the others. The claws cut me up quite a bit! I hit the ground hard, and All For One made a move. He rushed towards us and somehow exploded the area around us! He made his way towards Deku as all of us had been scattered by his attack. Deku fought valiantly against All For One, he hit him with a 100% Detroit Smash but the impact was reflected back onto him. Deku went flying into me and we both rolled across the ground.

(I.R.P.: Listen to "Might+U" by Makayla Phillips)

I tried to move, but it was like my body was weighing me down. I looked over at Deku, then at the other Pros. They were trying their best to fight off against All For One. I saw Annie struggle against him as well!

"Moshi Mosh!" I heard Shinobu from behind me.

Not only was it her, but the entire Hashira and Tanjiro! Also, the previous One For All users?! Great Grandpa helped me up, and so did Shinobu. All Might and Nana helped Deku up.

"This isn't how this ends Midoriya... Leonidus..." Nana told us.

"Just this once, we're lending you our strength!" Rengoku exclaimed.

"W-What...? How?" Deku asked.

"Simple! Like this!" Mitsuri smiled.

She split her spirit into two and phased into both of us. One after the other, they all did. Before Shinobu did, she told us that exerting our full power with their's might kill us. The last person that was left was All Might.

"Young Leonidus, Young Midoriya... Beat his ass, for me!" All Might yelled.

*THIRD PERSON*

All Might merged with both Midoriya and Leonidus, both the feeling of One For All and the energy of the Hashira's coursed through their veins.

"So, are they right...? We might die after this?" Izuku questioned.

"I'm not sure, but that's okay by me, If it's alright by you. There's nobody else I'd die fighting nobly with." Leonidus responded.

Midoriya looked at Alyx and nodded.

All For One looked behind him in shock, "W-What? How...?"

Izuku and Alyx looked at All For One, who quickly grew frustrated at the sight of the still living heroes.

"WHY WON'T YOU JUST PERISH?! YOU'RE JUST MERE CHILDREN IN A MAN'S WORLD!!" All For One shouted.

The area around him turned into a hellish storm of wind and fire. Midoriya and Alyx looked on as the storm grew larger.

"You feel it too, don't you? This really is it, isn't it?" Izuku wondered.

"Yeah, but that's fine. I'm sure the others would understand, we have to do this. We're trying to be the heroes we wanna be, right? No matter the cost? I'm sure everyone else will understand, Izuku." Alyx replied.

Both Alyx and Midoriya powered up to 100%.

"We'll protect everyone!" Izuku shouted.

"And we'll rid the world of your evil!" Alyx followed up with.

Alyx and Midoriya remembered their journey together, Izuku remembers what All Might has taught him as well.

"𝘐 𝘱𝘳𝘰𝘮𝘪𝘴𝘦, 𝘐'𝘭𝘭 𝘬𝘦𝘦𝘱 𝘺𝘰𝘶 𝘴𝘢𝘧𝘦, 𝘢𝘭𝘭 𝘰𝘧 𝘺𝘰𝘶!" Alyx remembered.

"...TO ALWAYS KEEP MY PROMISES!" Alyx shouted at the top of his lungs as his Overdrive ignited fiercely.

"𝘐'𝘮 𝘵𝘩𝘦 𝘋𝘦𝘬𝘶 𝘵𝘩𝘢𝘵 𝘢𝘭𝘸𝘢𝘺𝘴 𝘥𝘰𝘦𝘴 𝘩𝘪𝘴 𝘣𝘦𝘴𝘵!" Izuku remembered.

"...TO ALWAYS BE THE DEKU THAT DOES HIS BEST!" Izuku roared.

"YOU FOOLS! YOU CAN'T HOLD A CANDLE TO ME! NOW, DIE!!!" All For One unleashed the Hell Storm attack towards them.

Alyx and Izuku reel back their arms, "DETROOOOOOIT...!"

The two lunged their arms forward.

"...SMAAAAAAAAASH!!!!" They screamed in unison.

They created a powerful gust of wind that held the Hell Storm attack back, and with one last push of power, they break through! The area became surrounded in a blanket of wind and One For All energy! The boys were glowing a rainbow of colors! All For One, left unable to move, questions what they just did.

"W-What... What is this power?! HOW ARE YOU DOING THIS?!" He shouted to them.

They walked forward.

"THIS... IS HOPE." Izuku & Alyx yelled.

"THIS... IS PEACE." They screamed.

They both got closer to All For One. They reeled back their fists, and using the full power of the Hashira and One For All, they flew towards All For One! Their fists radiating multi-colored energy.

"THIS... IS... ONE FOR ALL!!!" Both of them roared.

The braveheart warriors, using the full extent of the power bestowed upon them, knew that this may be their last day alive. But to them, that did not matter, what mattered to them was the safety of the ones they love. Alyx & Izuku grit their teeth and clenched their buttocks for one last attack. Time seemed to stop, both Alyx and Midoriya felt a presence behind them. They turned around and saw Nana and All Might!

"Let's end this, once and for all!" Nana beamed.

"Yes! Let's end this!" All Might agreed.

Izuku and Alyx nodded in agreement and their focus returned to All For One, who was being held back by not only the force of One For All, but by the Hashira as well! Tanjiro glanced over at Alyx and smiled.

"𝘈𝘭𝘺𝘹, 𝘺𝘰𝘶 𝘩𝘢𝘷𝘦 𝘯𝘰 𝘪𝘥𝘦𝘢 𝘩𝘰𝘸 𝘮𝘶𝘤𝘩 𝘰𝘧 𝘢 𝘩𝘦𝘳𝘰 𝘺𝘰𝘶 𝘳𝘦𝘢𝘭𝘭𝘺 𝘢𝘳𝘦..." He thought.

Before time began to move, a memory resurfaced in Alyx's mind, one he didn't expect to see.

"𝘐'𝘭𝘭 𝘣𝘦 𝘵𝘩𝘦𝘳𝘦 𝘦𝘷𝘦𝘳𝘺 𝘴𝘵𝘦𝘱 𝘰𝘧 𝘵𝘩𝘦 𝘸𝘢𝘺! 𝘠𝘰𝘶'𝘷𝘦 𝘣𝘦𝘦𝘯 𝘮𝘺 𝘩𝘦𝘳𝘰 𝘴𝘪𝘯𝘤𝘦 𝘸𝘦 𝘸𝘦𝘳𝘦 𝘭𝘪𝘵𝘵𝘭𝘦, 𝘴𝘰 𝘐'𝘥 𝘭𝘪𝘬𝘦 𝘵𝘰 𝘳𝘦𝘵𝘶𝘳𝘯 𝘵𝘩𝘦 𝘧𝘢𝘷𝘰𝘳!" He remembered Laura's words.

Alyx closed his eyes and smirked, even though he couldn't remember who it was, the words felt like a warm send off. Both of the boy's eyes flared out the energy of One For All and time resumed once more. Behind them, Nana Shimura and All Might guided them to the path of victory, even though that path could've meant an ultimate sacrifice.

"𝘛𝘩𝘪𝘴 𝘪𝘴 𝘪𝘵... 𝘖𝘶𝘳 𝘤𝘩𝘢𝘯𝘤𝘦 𝘵𝘰 𝘸𝘪𝘯... 𝘛𝘩𝘪𝘴 𝘪𝘴 𝘰𝘶𝘳 𝘱𝘰𝘸𝘦𝘳!" They both thought.

"𝘎𝘰𝘰𝘥𝘣𝘺𝘦... 𝘈𝘭𝘭 𝘍𝘰𝘳 𝘖𝘯𝘦!" They thought again.

Both of them lunged their fists forward.

"𝘛𝘈𝘒𝘌 𝘛𝘏𝘐𝘐𝘐𝘐𝘐𝘐𝘚𝘚𝘚𝘚!!!" They screamed.

Leonidus and Deku made contact with All For One, as soon as they did, a flash of light covered the entire area. All For One was nowhere to be seen, incinerated in the full power Smash by Alyx and Izuku! The Heroes looked up, and a ray of shining light cast down upon a crater. The Heroes rushed to see the aftermath, and saw Izuku & Alyx, presumably unconscious! They rushed to the boys, hoping it wasn't too late...

*LEONIDUS' P.O.V.*

"Leonidus, sir! Please, wake up!" I faintly heard Sota's voice.

"Alyx, please!" Momo cried.

I slowly opened my eyes slightly and took a shaky breath in and out.

Momo signaled people over, "He's alright! Get over here, quick!"

(I.R.P.: Listen to "You Can Become A Hero")

"D-Deku... Is... Is he... Okay...?" I muttered.

I looked over and saw that he was right next to me, his left arm was missing! I looked down at my right arm, and so was mine. Luckily, he was breathing. Momo helped me sit up and the others ran towards us.

"S-So... Sota?" I asked.

"We all came as quickly as we could! I know we don't have our Provisional Licenses yet but we didn't want to sit and do nothing!" Sota exclaimed.

I looked around and saw all of the first years helping out with those that were injured. I remembered the question that news guy asked me, if the world would be safe with the next generation of heroes. I managed to smile a bit; I think we're in good hands.

"Oh my God! Alyx!" Annie yelled as she ran over to me.

She gave me a hug and looked at my missing right arm. I lifted my arm with all of the strength I had.

"T-There..." I muttered.

The piece of my arm was a few feet away from me and so was Deku's. Annie grabbed the lower half of my arm and brought it over. She healed it back on and it hurt like a bitch! I moved my newly reattached right arm. I looked over towards Deku who was just regaining consciousness. Annie moved over to Deku, and reattached his arm as well. Bakugo came over and knelt down beside me.

"Alyx, thank you. You don't know how much of a blessing you are... To all of us." He told me.

Those words carried weight to them, and I felt it in my heart. I don't know why they sounded so familiar, but I just started crying.

"T-Thank you... Thank you... So much... Bakugo...!" I wept while smiling.

Bakugo softly smiled and put his hand on my head.

"Damn, keep it up, you'll beat Deku's crying record." He joked.

We faintly heard Deku, "I... H-Heard that...!"

They all laughed, I would've but every part of my body hurt, so I just smiled.

"I think... I'm gonna... Take a nap now..." I told them before I passed out again.

Momo ran her hand through my hair, "It's okay, rest up, darling."

[The Next Morning...]

I woke up in the hospital, Deku was in a bed next to me. I was still in my hero suit, despite it being torn. I was wrapped in bandages and gauze around my waist, rib cage, and my left arm. I looked outside of the hospital window and noticed that the sun was rising, or was it setting? The clock on the wall said it was about 7:00 AM. Geez, I slept through the whole day! I almost went back to sleep until I heard someone open the door. Iida came in and so did Shoto.

"Good morning! We've brought you breakfast!" Iida cheerfully greeted.

I slowly sat up in the bed, "Hey! Thank you!"

I woke Deku up and all four of us sat and ate. I stopped eating as I realized something.

"Where's my sword?!" I frantically asked.

I looked on both sides of the hospital bed but only found my scabbard.

"Easy now, they've recovered the fragments of your sword. They've been placed safely in your dorm room." Iida informed me.

I sighed with relief, "Okay, thank you, Iida."

The doctor came in and cleared Deku and I to go. Wasn't it a bit early to do that? Then again, nothing felt broken, it just hurt like hell. We walked out with Iida and Shoto. Even though I slept for god knows how long, I was still super tired!

"Hey, Hey!" Nejire yelled over to us as she landed down in front of us.

"Hey, Nejire! Or should I say Nejire Chan?" I questioned.

"Either or works!" She beamed.

"So, did ya hear? People have been calling you two 'Japan's Demon Slayers!' Isn't that somethin'? Or was it another thing?" Nejire told us.

"Demon Slayers sound nice, I like that." I smiled.

Nejire stopped and tilted her head, "I've been wondering, where'd you get that scar on your eye? It looks so cool!"

"Oh, that? I hit my head there and lost my memory, I think? I guess that's what I've always thought. Hard to believe that happened a year ago!" I explained.

"Ooo, really? That's interesting!" Nejire exclaimed.

She sure still was that same bubbly girl! I couldn't help but laugh, she's definitely curious about everything!

"You guys need some help getting back to the dorms? I can do that!" Nejire quickly offered.

Before we could say a single word, Nejire shot out her Quirk and it circled around us. We flew into the air with Nejire and zoomed towards U.A.

"Nejire Chan, may we please land on the ground, I am starting to feel sick!" Iida yelled over to Nejire.

"Oh, come on, Iida! It's not that bad. I mean, just look at Shoto!" I pointed at Shoto.

"But Alyx, he's asleep." Iida noted.

I nodded my head, "Yep! Exactly!"

Iida sighed and closed his eyes. After a few minutes of flying, we landed at the dorms. We thanked Nejire for helping us out and she flew off back into the city. We quietly walked inside the dorms; everyone was still asleep.

"Alyx, you've never made breakfast for us, have you?" Shoto asked.

"Nope, if I did, at least half of us would be dealing with food poisoning." I admitted.

"So, you're telling me that Kirishima can cook better than you, and he almost burned this place down?" Deku questioned.

"Yeah, pretty much. But there's one thing I can do," I answered, "I'm pretty good at sleeping."

I walked upstairs to my room, but made a stop by Momo's room. I knocked on her door and entered her room. She woke up and looked at me, I smiled at her.

"I'm home!" I beamed.

I walked over to her, I gave her a hug and kissed her on her forehead.

"How are you feeling?" Momo asked.

I patted my chest, "Well, besides the rib pains and the stomach pains, I'm fine! I'm kind of surprised that my left arm isn't in pain though."

"What about your right arm? It did kind of get reattached, you know?" Momo grabbed my right arm and examined it.

"Oh, no! It's fine, since Annie healed it up, it's almost as if it never blew off!" I smiled.

Momo nodded, then she looked closer at my arm, "What's this?"

Momo pulled a long strand of hair off of my arm and looked at it. She handed it to me and I sniffed it.

"Alyx, what...?" Momo wondered.

"It's not Nejire's... Plus it's not the color of her hair, it smells like... Paper? No, some sort of blue-raspberry shampoo." I was focused on trying to figure out who it belonged to.

"I'm not sure, it definitely isn't anyone that I've met. They must've visited me while I was at the hospital." I guessed.

It did smell familiar though, I'm not sure why, however. I left Momo's room and went into mine. The sword fragments were laying on my desk, so I set my scabbard down next to them. I changed out of my tattered hero suit and into some sweatpants and a t-shirt. I laid down on my bed and took my well-deserved nap.
