In this world, there exists something that is called, Cursed tools.

To explain what Cursed Tools are and their origins in the most simple way, it's basically a byproduct when certain things were exposed in CE for a certain amount of time. It can be anything and the effect that each one carries greatly varies.

Now, given such a fact, Hiroyuki's body, after successfully performing the Core Reformation Technique, had obviously made some massive changes.

Well, just like how Curse Tools are made, his entire body, even though it only happened for just a couple of hours, was basked in a huge amount of extremely concentrated Curse Energy, and in the process, was forced to undergo an evolution.

Most especially speaking, his heart.

Since his heart is the one where he focused all his CE since the very beginning, making it the organ which was the most exposed, in the end, it stopped being a normal heart and changed into something that can only be described as, a Cursed Heart.

Or at least that's the name that Hiroyuki and Senjumaru decided on after days of careful observations. Because upon doing so, they found that, it does more than what they initially expected.

Core Reformation makes an Aura Core in one's body. And what the core does is basically Regulates and Refines Aura so the User would have a much easier time using and controlling it and when performing any kind of Technique or Arts, it would require less Aura.

But the Cursed Heart, which is supposedly just another version of that said Aura Core, does not only possess the usual Regulates and Refines function, but it also does more.

To give an example, thanks to the Cursed Heart, now, Hiroyuki's CEs are just constantly coursing throughout his entire body even if he likes it or not. Meaning, that even in its dormant state, his body will be always enforced with CE, making his overall performance always enhanced all the time.

Not only that but, since the original intention for the Cursed Heart is a core, it obviously keeps all the Curse Energies that Hiroyuki possesses and prevents a single amount of it from leaking outside of his body.

Practically making him undetectable in the process.

Cause everybody, be it a sorcerer or normal human, had an overflowing Curse Energy within them. Even the most talented Jujutsu Sorcerer cannot prevent their CE from leaking outside of their body. That is a process that no one can simply not do.

Not to mention that when using Curse Techniques or any Curse Related stuff, one has to even surge out their CE as much as possible for more efficiency. So hiding your CE inside your body is really not a thing that anyone would like to do in the first place.

Well, having an overflowing CE doesn't really mean that they would stand out all the time. Every Jujutsu sorcerer can use a technique that can make them not easy to detect despite this very fact.

Some can even make their CE vague enough that they would not be noticed even though they're already standing a few steps away from their target.

In the end, unless one possesses zero amount of CE in their body, there's no way they would not be detected by others who are sensitive enough.

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

However, according to the records, the inside of a human body is a domain of its own. To access it or peek through it, the shell has to be ripped out first. The very reason why the Kamo Clan, inheritor of the infamous Blood Manipulation Technique, can not just drain the blood out of their Target.

Now due to the regulation of Hiroyuki's Cursed Heart, his CE mainly operates inside his body. Unless he needs to perform certain Curse Techniques, his CE would perfectly stay still inside of him even though it's constantly circulating him.

Now given such facts, it's pretty understandable why Hiroyuki is practically undetectable if he wants to since, in his normal state, no CE will be sensed from him no matter how large his CE pool is.

It's all hidden by not only his body but by Cursed Heart as well.

Now these two functions, given how powerful their effects, are not the end of it, surprisingly enough. In fact, Hiroyuki can even feel that they haven't even found all the possible effects that his new heart offers.

There's literally more to unpack here.

But right now, that's not the most important thing anymore. What's more important is the next steps he now needs to take as well, and there are also the upcoming issues he has to deal with, issues that are mostly related to his newborn brother.

Things will be revealed as time goes by anyway. He even came out of it with almost no unexpected problems at that.

He simply couldn't be more grateful.

____ Next Scene Loading... ____

A couple of years now had passed and Hiroyuki is almost twelve years old now.

*Swish~*

*Swoosh~*

He is currently in his most favorite spot within the entire Clan, the Villa's Garden, all while doing some light training, as usual.

Given his current age and situation, it's not like there's much to do anyway. He can either move his body around or just slack off in the house doing nothing but some nonsensical stuff.

Well, he actually prefers the latter more.

But he doesn't have much choice right now since, he literally just finished his annual evaluation test a couple of moments ago.

Hiroyuki already received training from the clan a couple of years ago. The training is a mix of Curse Related Stuff and Basic Education.

Highlighting his learning with the Curse Related Stuff, since he started receiving it, he, or basically every youngling of the Gojo clan, is given an annual evaluation test, hosted by the elders themselves.

An event that is most likely made to witness the current generation's capability or potential. It is also a chance for the children here to be recognized so they can increase their status within the clan.

Well, although considered as the tamest one amongst the big 3, the Gojo clan is still run using hierarchy. So the better you are evaluated, the better you get treated.

And who would say no to that?

In any case, the Evaluation is basically just fighting against the instructors here. Those Instructors are the same ones who had taught the participating Children what they knew. The Children will then fight using all that was taught to them. They will then be graded in the end based on their performance. Simple as that.

On Hiroyuki's case on the other hand... Well, it started the same way as the other Children.

He fought his Instructor who supposedly 'taught' him everything he knew about Curses, even though at the point of his 'learning', Hiroyuki already knew everything there is to know about Curses thanks to Senjumaru.

Anyway, regarding the result of his test, not only did he manage to get the most perfect evaluation from the Elders, but Hiroyuki also managed to defeat his Instructor. Which, although still surprising, are not shocking for everyone at this point anymore.

Because this is Hiroyuki's fifth evaluation test already. And throughout those five evaluation tests, other than his very first test, he managed to defeat his Instructor and received the highest results as well.

He still received the highest result on the first one though, it's just that, he didn't defeat the instructor at that time due to a timeout. Resulting in a draw.

But giving credit where it's due, the Instructor that Hiroyuki fought is not really fighting seriously given that it's just an evaluation. He's even leaving some openings from time to time, just to test if Hiroyuki is keen enough to see it and take advantage of it.

Also, despite having an Innate Curse Technique, he only used some Curse Reinforcement Techniques throughout their fight. Nothing more even when he's about to lose already.

Plus, he was only defeated because he was thrown out of the designated ring. He is even happy when he is defeated, thinking that Hiroyuki managed to grow that much all thanks to his 'great' teachings.

And surely, things would've been so different if they were fighting for real and their lives were at stake. Well, Hiroyuki is still confident to come out on the top but the fight will surely be much harder than how it is normally for sure.

Overall, that's what just happened a couple of moments ago. And the very reason why Hiroyuki is currently in the Garden doing some training right now.

He simply cannot waste the adrenaline rush that the fight has given him. He had to take advantage of it before laziness started overtaking his body once again.

"Hmm?"

But, in the middle of doing that, he suddenly stopped because he started hearing some weird noises. The kind of noise that one would make when they are tired and out of breath.

Sighing heavily, as if he already knew what was happening, Hiroyuki started walking on a nearby bush where he felt the originator of that noise was.

*Rustle*

And upon pushing the tall bushes aside... There, he was met with a pair of blue eyes.

"... I see you escaped from Mom again, Satoru."
