Chapter Two:

The Sharingan is bullshit in the right hands. Many people use it to memorize Jutsu, copy Taijutsu styles, and place illusions on their enemies. But that barely scratches the surface.

Sharingan is God-like analysis taken to the extreme.

No more memory limitations. No more forgetting facts. No more making dumb mistakes after missing an obvious left hook because you were too horny to pay attention.

The ability to analyze anything and everything under your gaze. Down to the cellular level. Instantly.

His Sharingan could see every muscle twitch. Could see through the man's chest. And he was mildly impressed. Mildly.

'50% loss of function in lungs, no stomach, and increased strain on his entire body. His Quirks are Stockpile, Endure, Bio-Augmentation, and Shock Energy Reversal.'

Yes, I could now see quirks. Probably cause this world didn't have chakra. Aside from me. My chakra flowed through me if rather weakly. If I had to guess, I had the same levels as when I was four. Four! Oh, Izuna would be laughing at me.

"Who are you?"

'His hair style, his eyes, and his jaw remind me of All Might. The extensive damage has some implications however. If he's All Might, than I have some troubling thoughts for the near future.'

"I'm Yoshinori. All Might's assistant. He believes you are worthy to invest his time in. Maybe even inherit his quirk. Since it can transfer between individuals."

'He doesn't appear to be lying. However, my Sharingan detected a very slight hesitance upon saying assistant. So either he is All Might or related to him. However…"

"I'll happily accept his time for training but I'm afraid I'll have to decline on accepting his quirk. I hardly even know my own quirk's limits. Trying to learn and master both of them would be incredibly difficult, if not impossible."

The tone was respectful and calm, but Toshinori looked like someone had slapped him.

"Maybe after a while you might change your mind, Izuku Midoriya. There's a beach not far from here that is full of junk and has been a trash heap. Part of being a hero is public service. We can train while you clean the beach."

I paused. I wondered if I really wanted to deal with this. Dealing with trying to regain my former strength on my own for secrecy or learning the secrets of All Might as well as the Hero Program as a whole. Decisions. Hmm.

Well, I never specified all of my Sharingan's abilities and I did need to test them out. There are already significant differences between this one and his previous set.

For instance, his hypnosis no longer required direct contact. Simply tapping his chakra into the Slime Villain had allowed him to control him. Not to mention that the most he could've done previously was severely injure or confuse his opponents. The brain is very resistant to kill itself and was the main reason the Kurama Clan was so feared.

Not to mention his Sharingan can now see and analyze quirks and didn't cost him chakra. His eyes were passively active. As if they no longer required chakra to turn on. He didn't feel the slightest drain from it as he used to even in his youth.

This world was so different. 80% of the population has quirks of some variety. All of them with varied utility, skill, and experience. This world had technology that his people would only dream of. This world was both so much greater and weaker than his.

But, I realized quietly, it was also my world too. I was both Madara and Izuku. They were one and the same, a quantity greater than the sum of their parts.

"I'll accept the training. I also might like some more time to get used to my quirk."

I winced at the hesitance in my voice. And slightly scowled at the burning frustration. A part of me really wanted to become All Might's successor, but that was tempered by two giant factors. That being that I dont know the full limitations of my Sharingan and that my chakra is interacting differently in this world.

I needed to grasp my footing on what I can and can't do. That, and I silently acknowledged that I could always use the Eight Inner Gates to boost my physical power much like the Stockpile Quirk.

"I can accept that. I'm curious what you can do with it. Any hints?"

The not-All Might asked and sounded curious.

"So far, my Sharingan let's me see quirks, analyze what they can do to a certain extent, and slows down the perception of time by a factor of four, as well as letting me see everything down to the cellular level. So I'm curious how a man who says he's not All Might happens to have multiple quirks identical to the man himself."

My eyes narrowed as I looked at him. The moment of truth. I can see his jaw gaping slightly, the eyebrows widening in surprise and alarm, and the slight opening of his palms. His neck's very slight movement having jumped indicates a higher heartrate from the accusation.

He's All Might. I should get a sticker for surprising him like this.

"Holy hell, Izuku. That's incredible. From what I read in your journal, you already have quite the analyzing skills, and if what you said is true about your Sharingan quirk, then-."

Fast!

The man's fist blurred into motion, the Stockpile Quirk glowing like lightning through the man's body. I had less than a second to react, but my chakra and body responded automatically.

Using chakra to switch places with my pillow from behind me, and then simultaneously using my other hand to push back against the headboard of the hospital bed, launching my body slightly higher into the air from its current position, and then drove my foot about three centimeters above the pillow.

The end result was All Might found himself hitting a pillow, and then immediately seeing the pillow give way to a flying kick to the face. He gaped as he was launched back a few feet on to the ground. He looked up to see Izuku land on his feet on the bed, his legs crouched slightly, and his Sharingan gazing ominously back at him.

'This is a boy without training. A boy who clearly hasn't gained any muscle mass. A young teen who just dodged my fist at roughly 5% One For All.'

All Might was stunned and awed. Endeavor himself would have a hard time reacting to a punch like that within two feet and while laying down on a hospital bed. All Might himself could do it with One For All but certainly not in his base form.

'Izuku Midoriya. Your going to be a terrifying hero by the time I'm done training you. I sincerely think you can be my successor even without One For All.'

He still wanted to pass on his quirk, as his teacher had done, but he had no qualms in the fact that Izuku in his prime could probably give any One For All successor a run for their money. Easily.

"HAHAHA! IZUKU, YOU ARE MAGNIFICENT! I CANT WAIT TO SEE YOU AT YOUR PEAK! LETS GET STARTED!"

I grinned in agreement. My chakra had fallen below half in that one motion. Let's get started indeed.

I was less amused to find myself in front of a huge trash heap of a beach.

All Might had been quiet on the way to said beach but now he was grinning wildly at me. "These days, heros love to go around saving people, gathering glory and fame. But before all that, heroes had to learn that being a hero isn't for yourself."

He crushed a refrigerator into pieces.

"Heroes do community service. Both big and small. Acknowledged or unrewarded. Because it's the right thing to do. Many heroes do the little things in the background that are never really noticed. Like my parents who instilled these values in me. Everyone knows All Might, but no one ever asks who inspired All Might."

The man was in his inactivated form now, a silent serious tone in his voice.

I found myself agreeing to his reasoning.

"For the next ten months, you will clean this whole beach. We will train your physical body to its peak, and I originally had a training plan for you but that goes out the window since we'll also be learning your quirk and how it changes you."

"Let's get started then." I declared quietly. I took out a paint brush and some ink pots.

"What're you doing, Izuku?"

The man's tone sounded puzzled and I decided he didn't need to know what every seal was going to do. Just the basics.

"I am going to write seals on my body."

The man's confusion rose silently and I chuckled a bit. He'll see in ten months. They all will. My eyes narrowed in burning silent anger as Katsuki popped into my head.

They will see what 'quirkless' Deku can really do.
