In the Dimensional Gap
"Mmm… seems like an interesting being has been born," said Great Red as he wandered through the Dimensional Gap.
Who knows where he was heading, but meanwhile… POV: Ophis
"It looks like someone's about to turn this world upside down… ufufufufu." Said a small loli with black hair—none other than Ophis, the Infinite Dragon God herself.
In the Underworld
The Four Great Satans, or Maous as they're casually called, were in their monthly meeting when:
Sirzechs (Lucifer): "Well, that wraps up today's meeting, you may all—" He suddenly froze as he felt a terrifying presence. "What the hell was that?" The Ex-Gremory was stunned.
Serafall (Leviathan): "Sirzechs-chan, you felt it too?" said the young Sitri girl, equally shocked.
Ajuka (Beelzebub): "Sirzechs… that presence was terrifying," muttered the young Astaroth.
Falbium (Asmodeus): "We need to prepare for the future. Whatever gave off that aura might be a threat to the Underworld," said the bald one, looking unusually serious.
Sirzechs: "Calm down, everyone. Let's think this through. That presence lasted only a second before disappearing. We need to investigate whatever just awakened."
Everyone nodded quickly.
In Grigori
Over in the Fallen Angel faction, poor Azazel was buried under a mountain of paperwork, anime-style teary eyes and all, when something interrupted him:
"Mouuuu, I need a vacation. They've got me working like a slave here," Azazel whined when— "Huh? What the hell was that?" The little crow looked startled.
"AZAZEL! You felt that, didn't you?" said Cadre Penemue (N.D.A. BEST WAIFU EVER, FIGHT ME) as she barged into his office, clearly shaken.
"Heyyy, Penemue! Don't just barge in like that!" Azazel complained. "And yeah… that presence wasn't normal," he added seriously.
"Sorry about that," Penemue said apologetically.
"Don't worry. Just stay alert from now on. Whatever that was… it was a monster," he muttered, gazing out his window.
POV: Yuu
(Mmm… what the heck? Did I reincarnate already? But why can't I see anything… Wait, shouldn't I be coming out of my mother's belly by now?)
A sudden light interrupted my thoughts. (Looks like it's time to be born… here begins my cliché adventure. Yeah, cliché, but it's mine.)
Third-Person POV
In a hospital in Kuoh City, a stunningly beautiful woman with silver-gray hair, almost albino, and bright lime-green eyes was giving birth to a baby with pure white hair.
A few hours later, the delivery was over. Baby Yuu had been born.
"Congratulations, Mrs. Gojo. It's a healthy baby boy," said a nurse with a bright smile.
"So this is my little one… what a beautiful baby," Mrs. Gojo said gently, holding him close.
"KAORIII!" shouted a nervous man who nearly fainted at the sight of his son's birth. "How's the baby?!"
Like any mother, Kaori's killer instinct never disappeared. Poor Mr. Gojo trembled in fear.
"Yujiro, can't you see the baby's sleeping? Stop yelling like a maniac," she snapped.
He knelt, forehead to the floor, whispering, "I'm sorry. I swear as Yujiro Gojo I won't do it again."
"Alright, can I see him?" he asked softly. Kaori handed Yuu over, and Yujiro smiled warmly. "So you're my little champ."
POV: Yuu
I opened my eyes just enough to see a tall, handsome man with white hair and crimson eyes. (Heh, looks like I inherited his good looks.)
"You've inherited our ancestor's eyes," Yujiro said, astonished. "That eye color hasn't appeared in the Gojo clan for over a hundred years."
(So I've got the Six Eyes… This is awesome.) I thought excitedly. (Looks like this will be a family that actually loves me, huh?)
Flashback
A young boy sat in a small room, solving advanced-level tests in math, history, and other subjects. A tall man and a woman watched him closely.
The woman spoke coldly: "Listen, Yuudai. You're a genius among geniuses. Failure isn't tolerated in the Gojo household. Remember that… Don't be a failure like someone else I could mention."
The man added: "Understand this, Yuudai. Winning is everything. No matter the method, no matter the sacrifice. As long as you win, nothing else matters. Don't disappoint us."
End of Flashback
"Have you decided on a name?" the nurse asked with a smile.
"Yes, we'll name him after my grandfather. From today onward, you are Yuudai. Yuudai Gojo," said Yujiro proudly.
"It's a beautiful name for a beautiful baby," Kaori said, smiling.
Time Skip no Jutsu (Sharingan)
Some time passed after my reincarnation… and man, this sucks. Why? Because I'm stuck in a baby's body! All I do is eat, poop, and sleep. That's it.
I'm in the crib all day. No phone, no tablet. Just some crappy plushies and a rattle or two. (Ahhh… this is going to take forever. Guess I'll just wait until I can walk and talk.)
Time Skip: 4 Years
By the time I could walk and talk, I started training Chuuya's powers and Infinity. First, I reduced the density of small objects to make them float. Then heavier stuff, even myself. After that, I worked on increasing gravity on small objects in our yard.
Then I focused on Infinity from the Limitless—super useful. It was tough at first, but with the Six Eyes and understanding Achilles and the Tortoise paradox, I nearly mastered it.
When I went to the park with Mom, I secretly drained time from small bugs and birds. Not much energy, but it added up slowly. I also started some basic physical training—pushups, sit-ups, squats, running—but nothing too crazy for a four-year-old body.
One day, during lunch with my family, Mom said:"Yuu, kindergarten starts in just a few months."
"Really?! WOW, AWESOME, MOM!" I shouted excitedly.
"Save that enthusiasm for later, kid. I'm sure you'll make lots of friends," Dad said, ruffling my hair.
"Sure, Dad," I answered, though in my mind I thought: (Kindergarten, huh? That leaves about two years until the Himejima attack… I'll be ready for it if I need to intervene.)
Time Skip
So yeah… I turned five and started kindergarten. Annoying brats everywhere, but hey, I'm one of them now.
By this time, I'd nearly mastered S.E.D.C (Corrupted Pain) without triggering Corruption itself. I also began training Blue Rotation from Limitless, pulling small objects like stones and leaves toward me.
It's insanely hard to master—just a few uses leave me wiped out—but hey, progress is progress.
(Now I'm just waiting for the Himejima incident… Hehehehe. Killing a few of them will give me a LOT of time to practice… Just wait.)
