The Principal was sitting in his room, looking at the security camera footage of the first combat class of Class 1A.
As the recording ended, the Principal was rubbing his temples, trying to calm down.
This man, Blaze, assumed to be one of the strongest powerhouses of the world, was now debating on how to approach the black haired enigma called Ryomen Sukuna.
Besides him were two people, the vice-principal and a teacher, who were solemnly looking at the screen.
"The name 'Black Flash' is really fitting for that move, it's like naming a water spell 'blue' " Says the teacher, Mean.
"Well, I can't argue with that, Mean, but let's see what that does. Principal, please" says the vice-principal, Silvas.
Principal Blaze sighs before saying, "According to the medical reports, 6 of the boy's ribs were broken, by broken I mean shattered, there was also internal damage suggesting that there was a shockwave that damaged his body. The healing mage also said that it took longer than usual, precisely 32 minutes, to heal the boy, as the wound seemed to 'reject' his spell"
"That's quite deadly if used correctly" said Silvas
"The boy also seemed to be looking at his fist after performing the move, do you think that this is his first time doing this move, or maybe he can pull this off only rarely?" said Mean
"That is a good observation" said Silvas
"What do you plan to do, Principal?" asked Mean
"This boy seems to be much stronger than his peers, definitely stronger than all first-years, maybe even the second-years, though there might be a few third years that defeat him, but I also believe that he might be hiding more inside him, as he has always been nonchalant in his battles till now.
So, I will give him some 'special treatment', to test his capabilities.
I also have some suspicion about him being sent by villains, and being trained by them being the reason he is so strong" said the principal
Both Mean and Silvas thought for a few seconds and nodded in acceptance.
"I'll make sure to always keep an eye on him, not so much as to invade his privacy, but enough for us to get any hints of his strength and his . . . purpose" said Blaze before dismissing Mean and Silvas.
After the two left, Blaze sat there on his desk, seemingly in deep thought.

2 Weeks Later
Sukuna a sitting in a cross legged posture on a field inside the grounds of the academy. The air was fresh, and the sky orange, as sunset was closing in. The trees were swaying gently in the wind, while a fresh smell of flowers was spreading in the environment.
In this peaceful environment, was Sukuna sweating so hard that he made a lake under him.
He was trying to activate Reversed Cursed Technique, he had a little understanding of it from the anime, but he still couldn't achieve it.
He figured out that instead of repeating unlocked techniques, if he tries to achieve locked techniques, his Cursed Energy Proficiency will increase faster, as his body does have the ability to perform these techniques, but they have been forcibly blocked by the system.
He was close, like really close to unlocking Reversed Cursed Techniques, his Cursed Energy Proficiency was at 39.2%, he assumed that he would unlock it in the next 2 days.
In the last few days, he has been maintaining his neutral relationship with the main characters, Johan doesn't hate him for literally nearly killing him on the first day of the academy, but instead, he admires him for being so strong, as expected of a brute.
He dispelled some of Alexia's fear towards him, because it was REALLY annoying, he got some questioning glances from students, he also heard murmurs about him molesting here being the reason for her fear, and it was . . . weird, to say the least.
He also figured out that his 'pressure' that he emitted at the party works kind of like Conqueror's Haki, although it comes from cursed energy, not willpower.

Two days Later
[Cursed Energy proficiency +0.05]
[Cursed Energy Proficiency has reached 40%]
[Unlocking Reverse Cursed Technique]
[Reverse Cursed Technique Unlocked, current proficiency 0%]
A lot of information flooded into Sukuna's mind.
'Gojo was right, I really do feel like a God right now, [Unshakeable Heart] is ruining my narcissistic moment though, I WANTED TO SAY THE LINE MAN'
He took a kitchen knife from his room and cut his hand.
He focused on the wound and it started healing, it took 10 seconds for the shallow wound to heal, this greatly disappointed Sukuna, but . . .
[Reversed Cursed Technique Proficiency +1%]
.
.
.
After stabbing himself for a few hours . . .
[Reversed Cursed Technique Proficiency +0.5%]
[Reversed Cursed Technique Proficiency has reached 25%, subsequent acts of healing self-inflicted wounds will not increase proficiency]
'Bruh come on I was doing so well, no worries though, I can easily heal broken bones and such now, though deadly wounds are still a problem'
Sukuna now got really excited for the dungeon diving in a few weeks, the teachers would hold a class in which they throw students into low-ranked dungeons. At this time, the team of the main characters gets stuck in a wrongly ranked dungeon, it was supposed to be D-Rank, but it turned out to be a C-Rank with a high C-Rank boss monster.
He probably wouldn't be on the MC team, but he still can get injured by monsters being in other teams. His aim was to get Reversed Cursed Technique Proficiency to above 70% with this dungeon run, as he believed that that would be the point where he could regenerate deadly injuries and organ failures, he was not sure about ripping out the heart like the original Sukuna, but ripping out the liver was still an option, people say livers taste good, or is it just chicken livers, I don't know, I don't want to know, I need to calm down.

The Principal was sitting in his office, he got reports of Sukuna today, it said that he rarely went out of his room, and when he went out, he always went to a secluded place and sat down, the report said that he didn't do any movement but he used to sweat a lot, like a lot.
It was also seen that many of the clothes he gave for washing were drenched in blood, when the employees asked about it, he just smiled and walked away like a badass.
'Who wrote this report? Why are they fanboying over him?'
He has a decent relationship with the top scorers of the year, but didn't interact much with the other students.
'He doesn't seem to be physically training, well that checks out with his physique, but the blood stains . . . the people I sent to check on him were sure that he was not injured in any way, so it is possible that he has either healing capabilities or that is the blood of someone else, I sincerely hope that it's the former.'
'None of the other students reported of any injuries or such, neither are there any missing persons in the academy, so the possibility of it being the blood of someone else is low. It might be the blood of animals or rats or such, as he might be experimenting attacks on those'
'I need some coffee'
