Reincarnated Nezuko in MHA (Season 1)

#6 All Might vs Dark Oni

Nezuko's POV

I woke up to find that it was already dark. I prepared for my vigilante work and after 30 minutes, I headed to the city to start my patrol.

A few minutes in, I spotted a criminal attempting to rob an elderly woman. I approached them and delivered a swift chop to the criminal's neck, knocking him out. I grabbed the criminal and brought him to the police station, leaving him at the door with a cardboard sign that read, "I am a criminal." After a minute, a police officer found him and took him to jail.

I continued my patrol and after about 30 minutes, I sat atop a building, surveying the city. Suddenly, I heard fast footsteps approaching my direction. I saw a fist aiming to hit me and managed to dodge the punch. When I looked at who it was, I saw it was the number one hero, All Might.

"Surrender now, villain," he commanded.

"I'm not a villain, I'm a vigilante," I retorted.

"Regardless, you still need to surrender. We can do this the easy way or the hard way," he said.

"How about the hard way?" I replied with a smirk.

"Very well then," he said, rushing at me with a punch.

I summoned a sword and blocked his attack. I then placed my hand on the ground and used my blood spike technique. Numerous spikes made of blood emerged from the ground. All Might dodged them and closed the distance between us, delivering a punch. I was hit and sent flying, crashing into a building. I got back on my feet and saw All Might preparing to punch me again. This time, I managed to dodge it and punched him, pushing him back a bit. I then delivered a powerful kick. All Might managed to block it, but it pushed him a few meters away.

"I have to say, you are very strong," All Might said.

"Thanks for the compliment, but we're still in the middle of a fight. Let's save the compliments for when we're done. And it looks like the civilians have all left, so now we can't hold back anymore," I said to All Might.

"I agree. Now, I WILL NOT HOLD BACK, SO YOU BETTER GET READY!" he said, charging towards me.

"I CAN SAY THE SAME THING TO YOU, ALL MIGHT!" I retorted, charging towards him.

Our fists collided, creating a powerful shockwave. We exchanged punches, and I jumped back.

All Might then spoke, "I have to say, you are very strong. May I ask what's your name?"

"You don't need to say that I'm strong, and you can call me Dark Oni," I answered.

"So you're the Dark Oni. I have to say, you are my strongest opponent in a very long time, as expected from the number one vigilante," he said, getting into a battle stance.

"Same here, All Might. But I am not your strongest opponent that you have faced for now. But we still have to finish this. There should only be one winner in a fight," I said, taking a battle stance.

"I agree. Let's finish this, DARK ONI!" he said, charging towards me.

"Already ahead of you, ALL MIGHT!" I said, charging towards him.

All Might delivered a Detroit Smash, while I turned into my demon form. We were both going all out at 100%. We exchanged attacks, All Might delivering a series of punches and me using my martial arts with both punches and kicks. But I was getting overpowered by All Might.

"If this continues, I will lose. I need to find a way to beat this guy... Wait, I know! It won't knock him down, but it will paralyze him for a while to recover," I thought.

I used my Blood Demon Art: Explosive Blood on the ground, causing a giant pink explosion. It set some of All Might's blood, paralyzing him and weakening him without killing him. But this drained me as well.

"That was a very powerful attack," he said, on his knees and in his skinny form.

"Well, I win. You can't fight anymore, All Might. You can't even stand," I said.

"It looks like it... But don't get ahead of yourself. Next time, I will beat you," he said with a smile.

"I'm looking forward to that. But I have to say, if I hadn't used that attack, I would have lost badly... But the public can't know about you losing to me. And they can't know about this skinny form of yours. So let me just carry you away from here," I said.

"Alright then," he smiled.

I took All Might to the other side of the city and left him there.

"Well, All Might, I think this is far enough," I said.

"Yeah, it is. Well then, until next time," he said

"Yeah, until next time... But before that, I'll try to heal your injury," I said.

"Wait, you can do that? And why would you?" he asked.

"Because the world still needs you, All Might. Until he is ready, the world needs you. I will also help until then. Let's make sure that we weaken the evil so that when he arrives, he can cleanse this world," I answered.

"Who are you talking about?" he asked, looking nervous.

I smiled. "You know exactly who I'm talking about, All Might," I answered.

"How did you know about him?" he asked.

"I have my ways, All Might. Well, let's not waste any more time. Let me heal you," I said. He just nodded, and I used my flames to burn the poison in All Might, and then he returned to his buff form in an instant.

"Thank you, Dark Oni," he said.

"No problem, All Might. Until next time," I said.

We then went our separate ways.

I returned to my house, and when I got there, I collapsed to my feet.

"That was a fight. I don't know how I managed to get home without collapsing on the way. If I hadn't thought of that, I would have lost. I know in an actual fight, I wouldn't stand a chance. Thank God I used my brain that time, or I would have lost. And now that All Might is healed, he will become five times stronger or more than when I fought him earlier because he's back to his prime after healing him. I need to train to get stronger, strong enough to keep up with Izuku when the time comes... But before that, I need some rest," I thought. I then went to my bed and fell asleep.

Total words: 1107

Well, before we end this, I have to inform you guys about why All Might didn't recognize Nezuko. It's because Nezuko has the ability to manipulate her own body, like changing her size. So what Nezuko did was she changed her own body to make it look like she is 25 years old, even though she is just 15 (yes, she is 15 now; she has been in this world for 11 months now, and she was 14 when she was sent to the MHA universe).
