Cursed Technique is a power system utilized by Jujutsu Sorcerers to combat and confront Cursed Spirits that threaten humans.
The Cursed Technique is activated by pouring Cursed Energy into it, using one of two processes: Lapse or Reversal.
If Cursed Energy is likened to electricity, Cursed Technique is the apparatus that harnesses that power to function. Cursed Energy is processed through a procedure similar to mathematical formulas within the user to activate the Cursed Technique.
Hence, before Eiji could learn the Gojo Family's Inherited Technique, Limitless, he had to study advanced mathematics.
He needed to understand convergence, divergence, gravity, and more to master the Limitless Technique.
Eiji is not Satoru, born with Limitless.
He began his studies at the age of 4. The Gojo Family taught him starting from elementary school subjects, and currently, he is studying middle school subjects.
After studying, Eiji also practices martial arts until evening.
In essence, there's no playtime for him.
At 5 p.m.
In the Gojo Family dojo.
"Hah... Hah... Hah..."
Eiji lies on the wooden floor, gasping for breath, his forehead wet with sweat, and bruises covering his body.
"Amazing, Eiji-sama. Your martial arts skills improve rapidly every day. You're a martial arts prodigy."
The martial arts instructor praises while holding his sore face after being struck by Eiji.
If his friends find out he took hits from a 4-year-old boy, his dignity would be lost.
"Let's continue tomorrow; I take my leave. Eiji-sama."
After bowing, the martial arts instructor hurries to treat his face.
"Eiji-sama, drink some water."
Naomi comes with a bottle of cold mineral water and a dry towel.
*Glup... Glup... Glup...*
As Eiji drinks, Naomi helps wipe the sweat from his forehead.
Seeing bruises on Eiji's soft and white skin, she can't help but scold the martial arts instructor in her heart.
(Does that muscle-headed man have no restraint? He doesn't need to train a 4-year-old so intensely! Poor Eiji-sama)
In the past year, Eiji's body has always been bruised after martial arts training. Fortunately, Heavenly Restrictions grant him superhuman strength and endurance, and he'll recover the next day.
Nevertheless, Naomi feels sad seeing him seemingly enduring torture every day.
"There's still time before dinner; let's watch Doraemon."
"Um."
Eiji nods in agreement with Naomi.
Leaving the dojo, the two head to Eiji's room.
Under Naomi's guidance, Eiji often watches various anime to pass the time. After all, he's not allowed to leave the Gojo Family, and his entertainment options are very limited.
"Look, Eiji-sama, Nobita is doing something silly again."
Pointing to the TV screen, Naomi hopes to make Eiji laugh with Doraemon's anime comedy scenes. Unfortunately, it doesn't work.
Eiji doesn't even smile; he watches with a flat expression.
(Sigh... I've never seen Eiji-sama smile.) Naomi thinks disappointedly.
After that, they both watch TV without speaking.
.....
June 24, 2006.
Today, Eiji has a day off.
No studying or martial arts practice.
It's a rare holiday, but Eiji just sits on the balcony, gazing at the clouds.
He has no specific hobbies or interests, so he doesn't know what to do on his day off.
"This is boring."
After staring at the sky for a while, Eiji stands up, takes a few steps, and then jumps onto the roof.
With inhuman physical strength, it's easy for him to jump to the 10th floor of a building.
He jumps from roof to roof until reaching the outer edge of the Gojo Family area.
Others who happen to see him don't intercept. As long as Eiji doesn't leave the Gojo Family area, they won't stop him.
The architecture of the Gojo Family building is a traditional Japanese house. The area is vast and can easily accommodate dozens of people. Moreover, the Gojo Family headquarters is far from the city, so no outsiders see Eiji standing on the roof.
"School, huh..."
Eiji watches a group of students heading to school, feeling a slight envy.
As a Six Eyes bearer, he can easily see things from several kilometers away and with clarity.
In addition to long-distance vision, Six Eyes have other abilities such as their vision being comparable to high-definition infrared cameras, extraordinary perception, enhanced senses, and providing supercomputer-like thinking abilities.
All these are additional abilities.
The true abilities of Six Eyes are:
Allowing precise manipulation of Cursed Energy down to the atomic level.
The amount of Cursed Energy lost when a Six Eyes bearer activates a technique is almost zero, making it impossible for them to run out of Cursed Energy as they recover more than is expended.
A Six Eyes bearer can see the flow of Cursed Energy, giving them the ability to read and determine the function of someone's Cursed Technique.
With all these advantages, it's no wonder Six Eyes bearers are always at the top of the Jujutsu world whenever they appear.
"Yo, Eiji, what are you looking at?"
Suddenly, a playful voice of a man interrupts Eiji's thoughts.
No need to look, based on the vast ocean-like Cursed Energy, he recognizes the other party.
Eiji only knows one person with such Cursed Energy.
Gojo Satoru!
"Nothing. Just taking a look around. Welcome, Satoru Nii-san."
"Don't lie~ Let me guess. You must be peeping at the women's bath, right? Don't be shy; you're at the age to be curious about girls. But it's too early for you, at least wait a few more years, okay?"
"Eat this candy to suppress dopamine hormones."
Satoru takes out a candy from his pocket and puts it into Eiji's mouth.
As fellow Six Eyes bearers, Satoru knows how exhausting and burdensome it is because Six Eyes cannot be deactivated and are passive.
"Satoru, don't say weird things; you're a bad influence on Eiji."
Another man stands beside Satoru, helpless: "Don't listen to him, Eiji. Everything he says is pointless."
"Oi, Suguru, your words are harsh. I'm just guiding my young cousin onto the right path."
Satoru doesn't accept being accused by his friend.
"Do you think your previous words are suitable for a 4-year-old boy? If that's not a bad influence, then what is?"
"What did you say!"
Satoru bumps his forehead against Suguru's, and they glare at each other.
"Eiji-chan!"
Suddenly, Eiji is lifted and hugged by a young woman with brown bobbed hair.
"Let's leave these two perverted men, Eiji-chan. Don't become a man like both of them, okay?"
"Long time no see, Shoko-san."
Lifting his head from Shoko's chest, Eiji greets her.
"Eiji-chan is so cute!"
Seeing his childish face, Shoko takes him away.
"Hey, Shoko, don't equate me with Satoru!" Suguru protests.
"In reality, we can't be the same. My handsome face easily makes girls cheer with joy."
Taking off his glasses, Satoru displays the Six Eyes that look beautiful, biting his glasses on his lips, and winking with one eye.
"You're as narcissistic as ever." Suguru shakes his head and follows Shoko.
"I'm just stating facts." Satoru casually replies while putting his sunglasses back on.
