Five years ago

Steve Ray had become the World's youngest hero at the age of 13, and it had now been about a year. However, today was a day he was dreading the most.

His sensei was a few months ago diagnosed with a terminal illness that they didn't know about. Right now he was on his death bed as All Might stood next to Steve. 

Steve's sensei, Sir Hellfire was a person very close to All Might's master Nana Shimura and his old school teacher Gran Torino. Right now, they were going to hear something which only a few knew.

"Steve, people believe that Quirks have come around the 2020s, with that glowing child," he began as Steve nodded, crying.

"Well, that is not true. For a long time before that, there have been powers that could classify as quirks. The cursed techniques embedded in sorcerers, different abilities of a person's Chi, and so on. For us Chakra users, there exists something called Kekkei Genkai meaning bloodline limit," he said as a crying Steve nodded.

"Well, one of the strongest ones among them is called Sharingan. It is a red-colored eye with three black tomoe, you could say comma-looking things connected by a black ring. It allows the user to cast Genjutsu or illusions, since Toshi and Sohariko aren't familiar with our terms. And it also gives you extreme perceptive abilities, reflexes, and an ability to copy enemy's jutsu," he said.

"Y-yeah. But why are you telling me all this right now?"

"First listen to me. Now when you experience extreme sorrow and guilt, you unlock the next stage, the Mangekyou Sharingan. It enhances the powers of Sharingan and the user itself even more and gives you a few additional powers. And when you exchange it with someone, or give someone else, they unlock the Eternal Mangekyou. Mangekyou harms the user's eyesight the more it is used, but Eternal doesn't. You'll find the abilities in the scrolls I left behind for you.

Now you know that I have a fire quirk. However... I also have Sharingan," Sir Hellfire said as he activated his own Sharingan as Steve and others' eyes widened.

"For me, the incident that got me Mangekyou was Nana's death. Now... Steve, I want you to have this."

"... What! NO! I can't have that! I-I don't need that, it would be a dishonor to yo-"

"Steve, listen. I want you to have this as a present for reaching the top 10 on the International charts so soon. You're a natural-born prodigy, much like the legendary ninja Itachi Uchiha. I want you to go to even newer heights, I want you to save everyone with everything you've got. 

The ninja I mentioned is very special. You see, Uchihas, the clan I descend from, and the ones that have this bloodline limit were the misguided ones. None of them used the Mangekyou for good things, at least not from the start. 

The ninja I mentioned, however, was different. He did everything to protect, not to destroy. I want you to become like him, I want you to save people like I never could> I don't want you to lose someone like I lost Nana. So take it, and use it to protect your precious ones."

Present

Sukuna inside Deku was impressed. Even Gojo didn't emit such an aura. He was sure that this kid, if not on his level now, would soon surpass him. Both Steve and Izuku. All they lacked was experience.

Each step Steve took stuck fear in the hearts of the villains. Steve was walking slowly. however, his steps... they had a crushing implication.

"NOMU KILL HIM!"

The Nomu went forward to attack Steve, only for a translucent blue skeleton-like shell to cover Steve.

Imperfect Susanoo: What Steve used right now is the ability of Mangekyou Sharingan. It gives the user to make a gigantic humanoid which is used by the user to fight. It is considered the ultimate defense when in perfect form, and parts of the imperfect Susanoo are used to cover the user when attacked. Steve is using the chest of his Susanoo.

As the Nomu's punch hit the shell, shockwaves were released, however, there wasn't even a scratch on the armor.

Steve proceeded to grab the Nomu's face as he repeatedly punched it multiple times in the stomach, causing the stomach to explode.

"HUH!" yelled Shigaraki, confused.

"It has shock absorption, not nullification," yelled Izuku cheerfully from behind.

Steve tossed the Nomu to the side as he walked towards Shigaraki.

"N-nomu! DO SOMETHING!" he yelled as the Nomu once again healed and shot towards Steve.

"So regeneration too huh? Well, carbonized cells don't regenerate, so... AMATERASU!"

As soon as he said that Steve's eyes started to bleed as the Nomu was set on fire. Except... these were black.

Amaterasu: Named after the Goddess of sun, Amaterasu is another ability of Mangekyou Sharingan, which lights the thing which it was used on a fire that continues to burn for seven days and seven nights no matter what. Only the user can extinguish it.

"W-WHAT! NOMU! JUMP INTO THE WATER!" The nomu did as he was told but it didn't work as the water started to smoke and the flames spread.

"WHAT IS THAT!" yelled Shigaraki as he stepped back scared.

"MASTER WE NEED TO LEAVE!" 

"WHO ARE YOU?" yelled Shigaraki, irritated.

"Steve Ray, also known as Nightwatch," said Steve as he shot towards Shigaraki only for Kurogiri to cover him.

"YOU CHEATED YOU BASTARD!" yelled Shigaraki with wide eyes as Steve once again used Amaterasu, only to miss as Shigaraki's hand on the face lit up.

"I'LL KILL YOU NEXT TIME WE MEET!" 

The students just looked in awe. They had heard of the international number 4 hero, who was also quirkless, and thought that he got his position due to his popularity rather than power. Right now, however, they were just in awe of his power. If all Might went against him... they didn't want to admit it, but All Might would take a big L.

Kaminari meanwhile was just staring at Steve in awe. Steve since his debut had been his favorite hero. He still remembered seeing him walk onto the stage with his small size and small costume, his cute voice saying words of thanks to the world when he reached No. 2. Steve was 15 then, and Kaminari was 11. He always wanted someone to look up to, and Steve was that person.

Right now, seeing him in person, he felt out of the world. While Steve's Aura was threatening to others, as they were almost scared, to Kaminari, it was welcoming. He, like Izuku, felt safe around him.

As for Steve, he had noticed Kaminari and his reaction, but his mind had been occupied by the villains who were still there.

"Who is next?"

Hello everyone, so I hope you all liked this chapter. Do comment about your views about how the Sharingan was obtained by him. Though for those who aren't familiar with Naruto, this is how Kakashi got his Sharingan, so it is actually quite correct canonically.
