When the Son of the Sun Becomes the Strongest Older Brother

On December 7, 1989, a major event sent shockwaves through the world of jujutsu.

A child with the Six Eyes was born to the Gojo family!

And that's not all.

Mrs. Gojo gave birth to twins!

One of them was born with the power to bring clear skies across all of Tokyo and raise the temperature by ten degrees, like a walking sun!

During an interview with a jujutsu reporter, the mother, who wished to remain anonymous, said with happy tears in her eyes, "Having such wonderful children is a blessing I've received over three lifetimes. My partner and I will do our best to raise them."

.

Years later, the Gojo boys enrolled at Jujutsu High, and their classmates were left utterly aghast at the difference in their heights.

"Gojo Satoru, you're the older brother! How could you be so mean as to hog all the nutrients in your mother's womb?"

"Are you idiots? I'm the younger brother!"

.

Later, the younger brothers met, and the haughty (or are they?) siblings kicked off a love rivalry.

"You, the short guy with dark skin, stay away from my brother!"

"Watch your mouth! Only a perfect man like me is worthy of him!"

Karna: "..."

Little Gil:

Ever since my Master saved humanity, Chaldea has been in a bit of a lull. We either do events to collect the Saint Quartz maintenance gifts and summon Servants, or Master takes us out to grind.

Yesterday, Karna and Arjuna, those two unlucky guys, were taken to grind at the same time.

Archer Arjuna promised Master he'd be more useful than his brother (crossed out) rival, then charged off to battle without hesitation, with a Berserker following behind him.

But Karna ended up on the reserve team, and ran into a wild Holy Grail. The malicious power of the fanfic multiverse kidnapped him~ Leaving three clueless adults fretting in a panic: D

Sigh, never mind. My older self and my elderly self are fighting again. Adults really are one more troublesome than the next...

I own the OOC.

I wrote this for myself because I just wanted to read a Karna fic.

This FGO story is based purely on the game and has nothing to do with the official plot. (I've only played the game. I haven't watched the anime or read the novels.)

Theme: Karna, could you please stop talking like Tomioka?
