As the 2 went to the backyard, denki charged up his body with 500k volts, and got into a battle stance, while barry prepared himself amd activated his sharingan. Denki first rushed at barry using full speed, and because his whole body was charged up, his speed was insane, but still barry managed to catch every move he did using his sharingan.
(changing name from barry to Alex, idk it sounds better, and i found that the name Barry sucks)
Seeing a punch coming straight to his face, he instantly appeared behind him, getting a kunai, he placed it on his neck and said in a low creepy voice "dead." after he said that, they parted again, and this time denki wasn't planning on holding back, he immediately charged up his body up with 1 million volts.
After images were left every where as he rushed at alex at super speed, his speed almost broke the sound barrier, thankfully it didn't, not because alex would have lost, no. Denki's body isn't strong enough to handle the after math of breaking through the sound barrier.
Even though denki's speed was inhumane, who said the sharingan was something a normal human will wield. Alex's sharingan kept up, but still he had trouble keeping up, thankfully, denki can't keep going for long, so it was a battle of attrition at this moment.
As denki appeared behind Alex, he caught him of guard, and managed to land a kick on his back, alex was sent flying hitting a wall before getting back up. He spat out a bit of blood before charging even more Chakra into his eyes, his sharingan started changing, from the 2 tomoe, the third tomoe slowly appeared in his right eye, it had only appeared in one eye, his sharingan wasn't perfect yet, so only one eye got a 3 tomoe.
As he looked up, denki was on his limit, but he didn't want to win simply because his opponent ran out of stamina, looking straight into denki's eye, he was going to use one of the most famous techniques of the sharingan, "genjutsu" he muttered silently.
As soon as he said that, denki fell down simply like an idiot. After he was happy with the results, he released the genjutsu and denki quickly looked up before saying "waaah, that was sooo cool, howdya do it teach me nie-san"
As alex looked at him, he merely smiled as he pointed at his eyes.
"nie-san your e-eyes, t-t-they're bleeding" denki said as he pointed at his eyes.
Alex was first confused, after thinking about what happened, he merely smiled before going inside to wash up, 'i really should stop pushing my self, i still have lots of time, though that mysterious figure didn't say it, i can still kinda tell what our meeting in a hundred years will be for, it should be a battle between us, the candidates, or something like that. ' alex concluded to himself, he didn't know just how right he was.
--------------------------7 years later-----------------------------
*denki's house, Alex's room*
"Tommorow is UA's acceptance exams, i really wanna awaken the mangekyou sharingan before going to school tomorrow, from what i know, it will be extremely painful, but the results should be amazing, since even a 4 tomoe sharingan holds around 3/4 the power of a normal mangekyo, im excited, just imagining how powerful it will be makes me excited, man, I've been waiting 5 years for this day, ok according to the system, all i need to do is inject Chakra into my sharingan, then use that Chakra to fuse the 4 tomoes together, though i can't control what the final result will be, i still hve a hand in how it will come out, and how powerful it will be, so in the end it all comes down to this, let's do this."
After saying that, he sat in a lotus position on his bed, he used his sharingan, he slowly started inputting Chakra into his sharingans, at first, there was little to no pain, but soon the pain started adding uo, and he felt like someone had just poured lava straight into his open eyes, and that lava started melting his eyes, his body's tempruture skyrocketed, he started sweating before even that sweat turned into vapor, his body's temperature was still increasing, the pain in his eyes kept increasing to the point where he felt like his eyes had already melted off, and there was millions of ants crawling there.
"AAAAAHHHHH" he screamed at the top of his lungs before passing out with blood leaking out of his eyes, thankfully, he surrounded his room with Chakra to act as a soundproofing wall, or else the whole neighborhood will be jolted awake because of his screaming.
The next morning, he slowly got out of his bed before going to wash his face, looking into the mirror, he saw two trails of blood close to his eyes, washing it up, he activated his mangekyo to see how it looked, of course he was interested on how his mangekyo sharingan will look like.
(how his sharingan looks like)
Of course he was happy looking at his sharingan, it was a really cool sharingan, looking slightly like how itachi's own looked like, and it also looked kinda scary, he could use it to scare people without even putting them under a genjutsu.
Looking at the clock, something suddenly hit him, he was going to be late to the acceptamce exam, he only had 5 minutes before the dead end for arrival was, and his house was more than 2 kilometers far from the academy.
Quickly, he put on a black shirt, putting on some clean gray shorts, he quickly dashed out of the house's front door, running at unimaginable speed towards to the academy, without realizing it, he activated his 4 tomoe sharingan on his way there.
Thankfully he managed to reach the academy just before the dead end. Entering the class, or something like a stage room, he heard mic guy starting to speak.
*skipping the speech cuz i forgot what the f*** it says, and it kinda of a waste of time*
Standing with the crowd, he heard mic guy shouting "ARE YOU READY!!"
"YEAA"
The students replied in unison, before any one started moving, alex directly ran to the gate which was still opening, some students looked at him as if he was a student idiot, but he didn't mind. Soon after, they all heard mic guy saying jow there was no 1,2,3 in real life situations.
All students ran into the lifeless city while aled had already got his head start, without realizing it, he had activated his 4 tomoe sharingan. Killing the robots left and right, until he noticed lots of students running in one direction, looking uo, he saw a 0 pointer running around the city, looking at, he felt like it could be fun fight, he had already left his brother in the dust long ago, and he hadn't found a challenge in a long time.
Looking at it, he rushed at it, he didn't run full speed or else he would have broke the sound barrier, unfortunately for him, as he looked up, he saw a giant fist was just about to land on his head, it was merely 2-3 milemeters away from his head, looking at it, he muttered in a low voice.
"susanoo"
