Potential Man (Megumi SI/JJK/WC Fic)

Megumi P.O.V.

Jokes aside, I will not summon Mahoraga for obvious reasons. Even if my hand is itching to do it...

One of the things that I want to change is this loser mentality of giving up and self-destructing.

Now that I'm Megumi, I understand that he doesn't see himself or his own life as something important. He doesn't mind that much dying for someone else.

He is a good guy.

Better than me... Sorry, Megumi. I'm not that much of an altruistic dude.

But I think this is what makes this world good for me.

Selfishness here is rewarded!

Nanami dies and Mei Mei went to Malaysia after all... Just saying.

I will fit just fine.

Now, I rise from the bed. I know that I'm a 13-year-old, still in Middle School. I live with my sister, who must be making breakfast right now. Today is Sunday, so no school.

Normally I would practice with Gojo-san on weekends, but today she is on a business trip...

Wait... She... Gojo is a woman here!!

"Haah~ [Universal Calibration]..." Sincerely, not totally unexpected.

And female Gojo is hot. And she likes to tease me a lot about my puberty. Nice~

Aside from that, I don't have any contact with the other cast members...

I went to Jujutsu High sometimes and met Principal Yaga and Ieiri-san. But it was rare.

The principal is still a man, so not everyone becomes a woman here. So probably no female Todo, thank you Company.

Hmm~ I remember seeing some female Sukuna fanarts... But I accepted the mission to kill him. It will be such a waste if he is a woman now. Those arts made him very breedable.

And I like the ones that can crush me.

Anyway, Megumi jogs frequently so let's do that till I find a secluded spot to adjust to my new powers.

After all, even though it looks strangely normal to have these powers now, I was a normie in my last life.

"Oho~ Nice abs~" I whistle after checking my new body.

[Body Tune-up] did a good job in awakening Daddy Toji's genes.

I'm really a 13-year-old in anime. Like Gohan...

....

A good smell assaults my nose when I enter the kitchen.

My, now, sister is cooking something for us.

Now I'm conflicted... Normally, I would be disgusted by incest as much as the next guy, but...

I'm not totally Megumi.

And Megumi and Tsumiki are not blood-related. Famous magic words that make those strange scenarios okay here in Japan. You know how it rolls.

Some memories come to mind... Our relationship is a little strained now.

Megumi was in his rebel phase. Puberty and Tsumiki being a good two shoes that people take advantage of while I(Megumi) beat the bullies led to disagreements between us.

So we are at odds now. A little awkward...

Maybe I should've taken the [Communication Talent]...

What to do? What to do?

"Good Morning~" I was taken from my thoughts by her greeting me brightly while looking over her shoulder from where she was finishing her cooking.

She is making like all my previous thoughts are nothing.

She is smiling at me like always

"...good morning."

Okay, Megumi. You suck.

Why push away such a good sister, you tsundere?

I'm not any love guru, but is not like I need to be one to mend the rift left by childish tantrums.

Making use of that [Covert Talent] I sneak behind her and envelop her in a hug.

"M-Megumi!?" She says startled

"Tsumiki... I'm sorry for being awfully cold to you lately. You don't deserve none of that." I say. Against women always apologize.

"..." I can feel her body stiffen in my embrace.

I'm taller than her, my chin touches her ear.

"It's not your fault. I simply disagree with your way of doing things and at the same time I don't want to fight, I couldn't accept it... So I put my distance."

That was Megumi's true feelings.

My feelings are on her soft body. I was 17 before coming here, so it's legal. (Declaring to the Multiversal FBI)

"I noticed that I was being childish, but it was awkward to act like nothing happened... Wouldn't be fair without apologizing but I took too long to take courage to do that." I squeeze her tighter, my hands innocently caressing her stomach and hips.

I think she is squirming a little. [Sticky Fingers] huh? Very reliable...

"W-why this sudden change?" She asks with a trembling voice.

Would be too much narcissism to think she is suppressing a moan?

"Hm... It's silly..." Now [Covert Talent] comes into play. My voice is a little bashful while I lie easily "Well, remember that Avengers movie? The Civil War one." I can't say that I'm not Megumi anymore and my objective is to live a better life than the original Megumi.

"Yes..." In truth, the movie is Captain America: Civil War, not Avengers but whatever.

By the way, there are those things in this world too.

"That scene where Tony Stark doesn't say goodbye to his father and his father dies... They parted on bad terms. Forever in bad terms." I say slowly "I simply don't want to be on bad terms with you... My future job will be dangerous and..."

Suddenly she flips around and is face to face with me.

"Nothing gonna help with you!" She grabs my face and says strongly "Or me."

"..." Well, that's not true at all...

In canon, at least. I will try changing it. I have a plan.

She continues to stare at my eyes with a determined expression, a rare expression on her gentle face.

Oh, is she waiting for me to nod at her words?

"...I will protect you and I will not die." I nod.

She finally smiles and hugs me. Obviously, I hug back, my hands roaming her back a little too close to her butt.

We stay like that for a long time because I see no problem with it at all.

"Hng~" Now she finally moaned! I'm sure of it!

"Tsumiki?" I separate from her and ask "worriedly", that's why I took [Covert Talent]... to lie my way till I changed Megumi's personality to mine.

"I-It's nothing... A sneeze!" She says flustered and gets off me and turns around to hide her red face

"..." This is gonna be easier than I thought.

....

After eating breakfast, I said goodbye to my beautiful sister and left the house, I'm liking having a sister already, I was a single child back then.

The house is good, especially for only two teenagers. Gojo-sensei is taking care of everything apparently, she is stacked. Wait... Is she my Sugar Mama? I hope so.

Anyway, after some stretches, I go full sprint in the direction of a park that I know is nearby. My objective is the forest close to the park.

*Swish*

Ohoh~ That's some good speed~ And I'm not even using cursed energy to strengthen my body.

Anime Character bodies, especially from One Piece, are awesome.

The talents must be helping too.

I zoom through the streets, jumping a fence easily to arrive on the sidewalk where people usually jog.

I'm still holding back and I'm faster than anyone, moving the wind and raising some skirts by the sheer pressure.

Normally when you jog, you only go full sprint for some seconds before you continue at a moderate pace.

But I do not get tired at all.

All the way to the park I move at this constant speed, that is not my max by the way.

Finally arriving at my destination, I brake by putting my feet to the side, sliding through some distance on the ground till I finally stop.

"Hah~ That's great! Having such a healthy body is a damn blessing!" I can't help but exclaim in amazement

Damn, I should've hit the gym harder on my last life. Or practice some sport.

Now if I jump that fence I will enter the forest and I can practice some exaggerated mov- Hm?

I turn around to see a Cursed Spirit chilling close in a swing.

"..."

It's ugly but somewhat cute... Look harmless. Round like an egg, green, and with small limbs.

If not for how his orifices leak some black liquid it would've been cuter.

It's a good target.

"Divine Dogs." I make the designed handsign and two dogs emerge from my shadow, a black and a white.

Hm? They're bigger than I remember... If before they are like big wolves, now they are like direwolves from Game of Thrones.

"Anyway, I will analyze the changes later... Boys, I know that is overkill, but this is Jujutsu Kaisen, so..." I pat their heads and point to the poor cursed spirit minding his business "Jump him!"

With a growl, the two really jump the helpless cursed spirit. The white one steps on it, his claws digging into the spirit while the black one takes a huge chunk of the spirit's body with a bite.

Okay, that was really easy, as expected.

It must be a Grade 4, mostly harmless. I thought of going myself, but I need to start from below to be sure.

"Good boys." I praise while I approach and watch the cursed spirit dissolve in some black smoke miasma-like thing.

No body or any other vestige left.

Yeah, Sung Jin-woo Template would have a bad compatibility here, glad I didn't take it. Well, I plan to take it in the future, when I go to another world.

I'm going all in on the Dark Edgy Lord style in the future.

It's not cringe if it's real!

"Let's go boys, keep it up." I say to my shikigami before dashing to the small forest.

I will keep them summoned to test and study my ability.

...

After skillfully jumping and running around the forest, thanks to [Ahletic Talent], I finally arrive in a small open space, the shore of a small river.

"This will do." I say before sitting on a rock nearby. "Now, let's use the calming sound of nature to organize my memories and thoughts..."

Megumi/My life was pretty much as expected.

He only has a mindful relationship with two people, Tsumiki and Gojo...

Gojo-onee-san now... Her name is Gojo Satooru, putting more emphasis on the "RU", so is a more feminine name.

Whatever, my name is very feminine too because my shitty father didn't even care about my gender before naming me.

Megumi/I have no friends. That's good. Looking through my memories, with the help of my metaknowledge, I can remember the time I saved Angel's host.

That dirty girl with blonde hair.

And that's pretty much it... What a boring life...

The only other interesting thing to notice is that it appears that I influenced Megumi even before I woke up this morning.

First, is the personality. Megumi is not that ball of edginess and annoyance like in Canon, I can remember me and Gojo playing around. A good banter where I make the role of straight man.

I'm not that serious as Megumi and it appears that this was shown. It would suck to hold my sarcastic tongue.

Now second, and more important, it appears that Megumi benefitted a little of the Talents that I brought.

He was much better at fighting and in any other physical activity overall, even without using Cursed Energy.

Stronger too... I remember Gojo looking at me strangely after seeing some of the things I did.

Now I can understand that he is muttering under her breath and wondering if I inherited some of my Father's strength without the drawbacks.

That's a good cover.

And I think the Talents are suppressed but are there even before today.

I raise my hand and watch how easily I can move my Cursed Energy. A flame-ish purple glow covered my fist... Megumi wouldn't have made this that easily before.

So the Talents awakened fully with me today.

Makes sense, Megumi didn't use anything of the Template's power either.

Both he is advanced on the Ten Shadows. He already tamed Toad, Nue, Orochi, and Max Elephant.

Divine Dogs are the default.

I think he only tamed Max Elephant on his training arc to the Goodwill event when he was 15.

So 13-year-old Megumi with the talents I brought is stronger than the Starting of the Canon Megumi.

I think I can tame all others, with the exception of Mahoraga, after getting used to my new powers.

Maybe I can even tame Mahoraga before the start of the canon, I have two years after all.

"He made progress with the little boost in talent but..." I murmur before putting my hand on my shadow.

After some seconds I can sink it into my shadow and I can feel an open space on it.

"...He has no creativity with his power." I click my tongue at the guy.

How did he never think about that?

He only used the Ten Shadow Technique as the textbook said!

That's why people called you Potential Man!

Even Sukuna is confused as to why he ran from that finger-bearer. You're stronger than you think, idiot...

From the top of my head, I can think of many other uses for the Ten Shadows. Incorporating it into what Sukuna showed later...

"Now that I have this body and [Soul Talent], I will not waste it."

I can feel it... How versatile this power is! I can feel how can I mold it to my desires!

I almost want to scream to the sky because of how unidirectionally Megumi used it.

"Haah~ Forget it... I will practice later. Let's see what I can do with this new body and how much of the Templates strength I can bring." I say before rising to my feet and stretching my back.

...

With a boom and a crack sound the huge rock I just punched is reduced to smaller rocks and dust. And beyond an itchy feeling on the skin of my knuckles, I feel no pain.

"I should be stronger than Itadori, right? And this is without reinforcing my body with cursed energy"

This is the result of a peak fit body together with the Blackbeard Template. Well, the Darkness Devil should be physically strong too, even though it was not shown because there's no need.

The guy solo'ed the entire cast and killed half of them without even saying a "Hi. How are you?" first.

And remembering that the Templates are only on the Tier 4 for now.

I will be much stronger later. The physically stronger in this verse.

To keep things in perspective Captain America is a Tier 4 character. This shows how little of the strength of my templates I can bring to the surface.

Miles Morales is a Tier 5! This shows how big is the jump from tiers.

From Super Soldier Serum to Radioactive Spider Bite! It's a huge leap!

It shows how big my potential is and how much I need to work to level up templates.

This is also why I can only use so few options of the powers of my templates too.

I can't use the Tremor Fruit powers, no matter how hard I try.

It will probably unlock it when the Blackbeard Template is Tier 5.

On the other hand, I can use the Darkness fruit a little.

I look at my hand enshrouded in darkness and raise it.

A small vortex is formed and many small rocks, branches, and leaves are sucked into my palm.

After that, I put the same hand on the ground...

"Black Hole, right?" I say the name of the technique and the ground is engulfed in darkness.

But only in a radius of two meters around me. A little pathetic I would say.

Blackbeard can engulf an entire city, albeit a small, pre-time skip.

But I smile nonetheless... This shows how far I can go. Translating it in terms of physical strength, proportionally I will really be a fucking unit.

"I can also use the two types of Haki, but barely..." I comment while I look at my hands again and I can feel some "invisible armor" coating it. Very weakly, but is there.

I can also feel some presence nearby with Observation Haki.

I don't know if Blackbeard knows advanced forms of Haki, but it doesn't matter. He looks like the type of guy that focuses on his devil fruits.

With [Soul Talent] I can train beyond what he accomplished!

The only problem is that there's no signal of Conqueror's Haki... I tried, but I can't manifest it.

"C'mon Blackbeard... You're a 'D.' too, right? Don't disappoint me." I say before letting the matter rest for now.

In the worst case, I will buy [Added Potential] and spend 5 credits on Conqueror's Haki.

"If I can't manifest it before Canon..." I promise to myself, ignoring how I will acquire the said credits for now.

Time to focus on my other template powers.

The Darkness Devil is a mystery. He showed almost nothing of his power because he was too strong.

He blitzed through everyone. Unclear if he teleported or if he is just that fast. Probably the former.

But I can guess he can move on the shadows.

He has some sort of telekinesis and shadow/darkness manipulation.

And that's it.

Oh, he has that cool sword too. The templates give iconic pieces of equipment and I didn't receive it. So the sword probably is a conjured weapon.

Beyond that, he must have the standard devil package. An incredible healing factor, immortality, and all physical stats boosted.

And that's it. That's all that is shown. I will need to discover for myself the rest.

I raise my two hands this time.

In one, a ball of darkness is slowly conjured and the other looks empty.

Thrusting my hands in opposite directions I see the ball of darkness flying and taking a huge chunk of a tree, and an invisible force hits some trees too, breaking it in half.

The Darkness Devil and Makima appear to have something similar to the Force of Star Wars. Some Devil-based telekinesis.

Sounds handy.

The Darkness Devil is a Tier 8. Stronger than even Sukuna and Gojo.

He is my assurance that I will be the strongest eventually.

My assurance to defeat Mahoraga, so that I can defeat Sukuna.

"Tier 4 is very weak... 4 tiers till Tier 8. An abyss of training ahead. Even with the Talents will take years." I comment, noticing that I am not much above the average sorcerer now

I can't let the possibilities go to my head.

I don't have that much power now. Till I'm really strong I'm only that... Potential Man.

Let's change that!
