After 5 long and extremely annoying years later canon has started I've seen Izuku cleaning the beach a few times that I go by and check. Am I going to help Izuku? Definitely not in my past life he was my least favorite part about the anime the fact that he get's nervous while talking to girls on the phone is just in one word pathetic. Also the fact that he really thought he had a chance in getting in UA without training your body or taking martial arts classes while being quirkless even people with quirks trained their body like Kendo from 1-B with the big fist quirk.
The only other thing that's changed in the past 5 years is my body, I now look exactly like Sasuke at the start of Shippuden which has gotten me even more fangirls which is extremely annoying the only girl I would even think about being with is Lady Nagant because she has the same ideology as I do, who knows maybe I'll even start my own version of the Akatsuki and recruit her.
In terms of training I managed recreate Naruto's Rasengan I also recreated Boruto's Vanishing Rasengan, but I still haven't been able to add my fire nature yet, maybe because lightning is my main element and fire is second. I also trained my senses other than sight much like Madara when he lost both his eyes and still somehow managed to fight off every tailed beast, that man truly did deserve to be the second Sage of Six Paths.
The most important thing I accomplished over the last 5 years is mastering my wind nature. Since the Rinnegan gives me all 5 natures I've been working on mastering all of them although the one I mainly focused on is wind to one day recreate the Rasen-Shuriken just incase I need some major explosive power one day.
With the UA exam only two weeks away I already decided that I'm going to set the all time record just so everybody knows their place, but I'm not going to use my EMS or Rinnegan only my chakra or normal Sharingan since I can't just show everybody that I can destroy a city without breaking a sweat, after all the hero commission would be crawling up my ass like the power hungry group that they are.
After I put on my clothes and leave my house I start making my way to the beach that Izuku's cleaning to "accidently run into him" and see if he wants help or if he's actually committed to his training and decline it.
(Regular POV)
Two people are seen standing and talking on a beach one is a skinny man with blonde hair name Toshinori Yagi AKA All Might. The other person is a semi-muscular green haired kid named Izuku Midoriya.
As there talking about the UA exam in two weeks they both hear somebody say "Yo Izuku".
(Sasuke POV)
After I announce that I'm here they both turn to see me while Izuku recognizes me and greets me "Hey Sasuke what are you doing here?"
"I've been coming here a few times since somebody has started cleaning the beach" I lazily reply. " Are you the one that's cleaned the beach" I ask him.
He nods his head while saying "I did it for my training for the entrance exams"
Honestly while I don't like him as a character it is impressive that he managed to clean the entire beach and follow All Might's exercise plan without messing up, I don't even think I would've been able to do that.
"Oh, and this is Toshinori Yagi he's been helping me he's kinda like a personal coah" Izuku says while nervously chuckling.
Toshinori looks at me and says " Yes, it's been a pleasure to help Young Midoriya complete his dream and go to UA."
I stare at him for a few seconds and eventually reply " Sasuke Uchiha, hmm you kinda look like a skinny all might" while inwardly smirking.
Of course after I say this they both start sweating and denying it while trying to play it off as a joke. Eventually I get tired of mentally torturing them and tell them that I'm going back home after wishing Izuku luck at the Entrance Exams.
After I get home after training for a few hours I start mentally preparing myself for everything that's going to come in the future "I'm going to act like a normal student until the battle between All Might and All For One and then when they're both weakened I'll go in and kill both of them and tell the world that the God of the New World has come to bring peace to this world by rebuilding it.
