Time skip.
After a few weeks of working on his later project in his house basement, he was finally able to finalize his new project.
A pill that temporarily boosted a sorcerer's stats, giving them access to 120% of their potential during a fight for a short time.
It's basically the amp someone gets from using a black flash. Anyway, he had helped the jujutsu sorcerer live as much as he could.
He also helped Nanami enter that grade one threshold, if he was being honest, apart from maybe Clan heads, that were elite grade one, Nanami was now way stronger, Keitaro had helped the man with a couple of dozen binding vows.
He wrote a little book and gave it to the man. The book was mostly about how binding vows seem to work on the law of equivalent exchange, but at the same time, that law could be exploited.
Nanami's Ratio Technique divides his target into a ratio of 7:3, creating a weak point that amplifies his strikes. To enhance it, Keitaro went to the trouble of thinking of good vows, for it.
Possible Binding Vows:
"Absolute Ratio"
Condition: Nanami must always attack the identified weak point. He cannot strike any other area of the target.
Benefit: Amplifies the destructive power of his strikes significantly, potentially one-shotting even special-grade curses or fortified defenses.
"Limited Targets"
Condition: Nanami can only use his Ratio Technique on a single designated target at a time, chosen before combat begins.Benefit: His Ratio Technique becomes unblockable, ignoring protective barriers, armor, or defensive techniques.
"No Retreat"
Condition: Nanami must remain within a set radius of his opponent (e.g., 10 meters) once his Ratio Technique activates. He cannot retreat until the enemy is defeated or disengages.
Benefit: His attacks gain exponential power with consecutive strikes, and his precision increases to near-perfect accuracy.
"Shortened Lifespan"
Condition: Using his Ratio Technique causes accelerated aging, shortening his lifespan by a specific amount (e.g., 1 day for every strike).
Benefit: The 7:3 weak point now applies to all forms of defense and offense, such as barriers, domain expansions, or projectile attacks.
The last thing technique was more of a last resort than anything, if Nanami used it, let's say he sacrificed like 1 year, Tada, he can now one-shot a special grade, and there would be nothing left.
So yeah, apart from Keitaro and Satoru and Maki, Nanami had the hardest-hitting punch of any sorcerer.
Maki is a heavenly restriction user, who has been learning under Keitaro for quite a while now, matter of fact she started jujutsu high next year, she was practically a special grade in all but name, Keitaro felt maybe, just maybe, he had tipped the balance of the world to the side of the sorcerer.
Probably didn't help that Megumi had practically tamed all of his shadow except Marahoga, it probably didn't help that he had removed that mentality that the boy had, guess having your ass handed to you by a clone truly built character.
Wonderful, he felt like he was creating little monsters, maybe he might bring the golden age of jujutsu back, he wasn't that greedy.
And thus once in a while, he would publish a book about curse energy and make it available for any sorcerer who might want to read it.
So stuff like basic curse energy reinforcement, to very enhanced curse energy reinforcement was covered, the quality of sorcerer has gotten better, to the point that the average sorcerer in the modern age was sitting somewhere in grade 2.
They were barely any grade 3 or 4, Keitaro had found out of the way the elders would pray on the weak, and thus, he made stuff like simple domain and curse energy reinforce common knowledge and just to piss the elder off.
He created a new fighting style that put the new shadow style to shame, basically an upgraded version of it.
With that, their old sorcerer was quite small, and the sorcerer they had now, would eventually leave them at some point or just die out as well his stuff was better.
He didn't think of what he did as much, all he did really was help the average sorcerer achieve strength, now anyone jujutsu sorcerer regardless of their technique could at least achieve grade-one level strength if they worked hard enough.
The books were there for the taking.
Strangely enough, The Inumaki clan reach out.
He never expected people from the clan to reach out to him, or even let him study curse speech from up close, well granted they had something they had to gain from it so there was that.
For his help, he had them go under a vow, basically, it was something along the lines of, they would help his students if need be, as in protect them from the other higher up, or just a favor from them really.
The reason he made the vow to begin with was quite simple.
He didn't trust the higher-ups much, and the best way to get them to cooperate with him was simply by having their lives on the line.
They all knew that not abiding by a binding vow did so.
Anyway, after studying curse speech for like a month.
He had some light solution.
"Voice of Command"
Condition: The user can only use their Cursed Speech on a limited number of commands per day (e.g., 3-5 commands).
Benefit: Each command becomes exponentially more potent, allowing the user to enforce absolute obedience or affect multiple targets simultaneously without splitting power.
"Echo Effect"
Condition: Every command issued with Cursed Speech also inflicts a physical backlash on the user's body (e.g., pain, exhaustion, or internal injuries).
So the damage would now affect their whole body instead of their throat alone.
Benefit: Commands echo repeatedly in the target's mind, making them deal a lot more damage as you know, the user gets hurt by using it.
"Life for Power"
Condition: The user sacrifices a portion of their lifespan (e.g., days, months, or years) with each use of a command.
Benefit: The cursed energy imbued in their words becomes so overwhelming that it can compel even special-grade curses or Jujutsu sorcerers with strong resistance.
"Truth in Silence"
Condition: The user must remain silent for a set period (e.g., 1 minute, 10 minutes, or an hour) after issuing a command.
Benefit: The next command gains absolute, unbreakable enforcement for a short duration, regardless of the target's resistance.
"Single-Target Focus"
Condition: The user can only affect one target at a time.
Benefit: The effectiveness of the technique is greatly amplified, allowing the user to impose commands even on beings immune to cursed techniques.
"Death of voice"
Condition: The user would be unable to use curse speech for a long period after the command.
Benefit: Curse speech gains a huge buff due to the user practically sacrificing the use of their technique for a long time.
Example: Inumaki could use the don't move command on Sukuna while he was fighting Gojo and instead of instantly dying due to the sheer gap between them, Inumaki would simply be unable to use curse speech for a long time afterward....Ie a month.
The clan seemed quite happy about the news, Keitaro even had Mai make a curse tool for the boy, while wearing it, he could speak normally, and the curse tool practically just removed the curse energy from his words.
Thus practically allowing the boy to speak normally.
Fun, construction was truly a goated technique, granted he was hard carrying Mai through her journey right now as her Ce level was low.
The sister usually had the seal active, which fixed her low Ce problem, he had her go to England to train with Edgar for a whole year.
That was nice.
Eleanor had practically become the head of her house as her husband was still well....special....Tldr, he was in a state that people would be in with an extra chromosome, or like being left in Satoru unlimited void for 3 hours.
He was brain dead... like 25% of his soul had been destroyed, Keitaro did offer to heal him, but Eleanor's response was basically, that he was better like this.
Well good on her, though Keitaro could tell she had something for him, but kept it professional, her soul would sometimes give off a pink color anytime he was around.
He doubted she would stop him if he tried to make a move on her, and probably wouldn't even be against getting pregnant.
Though Keitaro did not entertain that thought for long, he was engaged, there was no way he would be seen clapping some noble's chicks.
Speaking of which, he meant Yuki, she was quite fun to be around.
She had quite a bumbly personality, and he had a lot in common with her, they met while he was in Greece, and her personality could be summed up to, Kushina but without any restrain, but she was smart, and with her help, he further his research of the soul.
He felt like the heaven themself were tempting him, however, he kept on going with his morals, maybe if he had met her earlier things could have been different.
Apparently, she was in Nepal around the same time as him, she left about a day before he came. {A/N fun fact, She was supposed to be there on his first trip as she was the original love interest}
Anyway, he share notes with her, had a spar with her, and she hit like a fucking truck, and blew his hand right off with one singular hit.
Thank heaven for Rct.
When he asked her, why her soul was so similar to Riko, she said it because she was once a tar plasma vessel.
So much news, and holy jeez.
He felt like his brain was going to explode, but it was so fun.
Over the years, his rivalry with Satoru got fiercer.
The score currently stood at...
{99-99}
They were tied, in terms of win. When a match ended in a tie, Keitaro nor Satoru counted it, it just went toward the tied category, which currently sat at a comfortable.
{200}
Ok....so maybe, there were a lot more equal than he thought, 200 fucking ties.
Well, name the game and chances are, they already played it, they were once that time they played soccer, was fun, may have left the kids traumatized but oh well.
Satoru had grown a lot, now.
So much in fact, that he could now have a relationship with other people...granted, Keitaro had to beat it out of him...not literally, but slowly, like a first having a lot of group hang out, slowly over time let him chat with someone else.
Very slowly, letting him be....himself, letting him be Satoru.
Shit took him 3 years...he wonder what the Gojo clan head was thinking messing the man mentally so badly.
Keitaro had made it, his little mission to have little notes about curse techniques on how to optimize them.
He sure hoped those notes would not be used by someone in order to commit mass genocide.
His first ever one was about his friend's curse technique.
Geto's Cursed Spirit Manipulation
Geto's ability to control curses is already immensely versatile. To strengthen it, he could take vows that enhance his control, expand his army, or increase his synergy with the curses.
Possible Binding Vows:
"One Life, One Curse"
Condition: For every curse he absorbs, a portion of his own life force is sacrificed permanently.
Benefit: Depending on how much of his life he gave away, the curse would gain a significant boost upon being under his command, and the curse limits on strength would be lifted, Ie, the curse can still grow stronger, only during the time period this vow active, Ie, the amount of his own life he decides to sacrifice, so one day mean the curse has one day without the limiter.
The stronger the curse the more of his life he would have to sacrifice, Ie a special grade curse would require one year in order to grow for one day.
As in a grade four with the same amount of time, can grow until it reaches semi grade one level.
"Cursed Overload"
Condition: Absorbing a curse causes Geto immense physical pain and damage. Overusing this ability could lead to fatal injuries.
Benefit: The curses he absorbs temporarily enhance his physical capabilities, granting him curse-like traits (e.g., regeneration, enhanced durability) while they are under his control.
There was another vow in there, where the life of the grade four curse would be sacrificed kind of like Meimei bird strike in order for their attack to have more hmph behind it.
There was also the fact that he could murder a sorcerer without curse energy, create a vengeful curse, and have that on his team.
Possibly were quite great.
As far as the jujutsu world was aware, Keitaro was the most knowledgeable about curse technique and the most versed in stuff related to curse energy.
Though Keitaro himself thought he ranked lower than Tengen and the killer of his parents, in terms of knowledge alone.
In terms of power, he ranks best or second best depending on the time of year.
Anyway, currently, Keitaro could be seen adjusting his sunglasses, yup he was on vacation, he was currently in Sydney, Australia, with his best friend.
"You feel that, Keitaro?" Gojo said, grinning wide and spinning in place with his arms outstretched. He wore a gaudy Hawaiian shirt and khaki shorts that made him look more like a tourist than the strongest sorcerer alive. "That's the freedom of being far, far away from all the drama of Japan. Just us, the sun, and—"
Keitaro cut him off with a raised hand. "And you gambling away all your money again, probably."
Gojo gasped dramatically, clutching his chest like he'd been shot. "Excuse me, *sir*, I am a refined man of taste. Gambling is a *sport*, not a vice."
"Didn't you lose like 400k last time"
"Pocket change really," The man said shrugging his shoulder...Keitaro felt like he was losing his grip on reality...400k yen was pocket money for this guy.
Granted, he could spent that much money without blinking an eye, however, he used that money to gain more knowledge about curse energy.
In his little research, he found stuff, like legends about gods and demons, stuff like that.
Humanity seems to have been cursed a while back, like a long ass time back.
He did ask to speak to Tengen about stuff like that, with Tengen, he learned quite a bit, it was fun speaking about the best barrier user ever.
When he presented the idea of a barrierless domain, Tengen asked him what gave him the idea, he said a note he found in a book.
The good news, a barrierless domain existed, The bad news, was Keitaro had no idea how to make one, the best he could do was make his domain exterior shell harder so it could withstand the attack for longer.
Even more bad news is that Ryomen Sukuna's domain was barrierless, worst news, someone named Kenjaku has a barrierless domain.
Good news, he lost to two Six Eyes users in the past, and considering Satoru was basically the strongest Six Eyes Limitless user to have ever lived, this man was practically fodder to him.
Bad news, Tengen was slowly turning into a curse.....Good news, Keitaro managed to stabilize her with a seal, using some of Yuki Dna as she was once a star plasma vessel and whatever remained of Amanai's soul, and the seal was made.
Tengen no longer was a thumb.
Even more good news, Tengen offer to teach him.
Even more good news, his barriers have gotten a lot better.
Good news, Akane now had 9 tails, she was still a Kitsune, not a Kawai fox girl, which was good.
Gaining her 9 tail seems to grant her even more buffed states, alongside buffing her illusion ability to hum, busted levels, though the illusion can be shattered if the sorcerer is very good with curse energy and is a good fighter in general.
For example, against someone with no clue about her illusion...They like Kyoka Suigetsu, you are cooked, against someone like Satoru, it is still like Kyoka Suigetsu but with the small fact that due to Satoru's six eyes and his eyes for detail, he knows the weakness and thus can break out.
Alright enough about how busted everyone became and how a certain king will be getting fucked raw no rubber later on, lets get back to the vacation.
Keitaro shrugged Satoru's arm off, though he couldn't help the small smirk tugging at his lips. "Someone has to keep you in check. Who else is going to stop you from buying a kangaroo and trying to bring it home as a pet?"
Satoru gasped again, his eyes lighting up. "That's a *great* idea! I could name it something cute, like... Kanga-chan!"
"Absolutely not," Keitaro said firmly, there was no way on God-green earth, he was letting this shit happen.
---
The duo made their way to the heart of Sydney, where Satoru insisted on visiting every tourist trap imaginable.
They took selfies in front of the Sydney Opera House, with Satoru striking increasingly ridiculous poses until Keitaro refused to take any more photos.
They wandered through Darling Harbour, where Satoru spent an absurd amount of money on souvenirs, including a stuffed koala he immediately declared as his "travel buddy."
"This little guy is gonna bring me luck at the casino," Satoru said, holding the stuffed koala aloft like a trophy.
Keitaro arched an eyebrow. "You realize it's just a stuffed toy, right? No magic, no cursed energy—just fabric and fluff."
"That's where you're wrong, my friend," Satoru said, wagging a finger. "This koala has the *spirit* of a winner. Trust me, Keitaro. Tonight's gonna be our night!"
---
Satoru then proceeded to go 30-0.....No win at all, none, nothing at all.
Keitaro made sure to savor each and every second of it.
Satoru was not lucky at all, Keitaro enjoyed every second of it.
"23 on Black"
"23 on red"
And just like that Satoru lost 150 thousand US dollars while Keitaro got a bit richer.
By the end of the day, the so-called good luck plushie was gone.
A lapse blue took care of it.
Keitaro had expected to see strong curses...all he got....was nothing. All the curses within a 10-mile radius of them, fled at the mere smell of them...well guess that's what happens when you are too strong.
Oh well, still had fun watching Satoru wrestle with an Alligator
"Satoru, I don't think we are meant to ride those," Keitaro said looking at the Ostrich.
Satoru with no care in the world jumps aboard.
"Stop being a wimp...what is the worst that could happen"
....
....
Being fined 500$ for traumatizing an Ostrich was not in his Bingo card for the year, nor was Satoru beating an ostrich to submission but here we are.
"You punch it..."
"It deserves it"
"...."
....
...
His friend may be a special grade.
A/N...Yes, This chapter was basically a sum up of everything that has happened in that time skip.
