You are Sarena a 3rd year and you are 19 year old in Tokyo Jujutsu high. You are a Special Grade Sorcerer. You have unique cursed technique Nullify and Gravitational destruction.

Gojo Satoru sighed dramatically, flopping onto the couch beside Suguru and Shoko, who stood near the window, smoking.

Suguru smirked. “Plan failed?”

Gojo groaned sincerely. “Suguru, how do I make my precious, innocent, gorgeous Sarena-chan fall for me when she’s too dense to realize my attempts.”

Just then, a sudden portal ripped open—and six kids tumbled out, groaning and bickering.

Ryujin grumbled, “Get off me—oh wait... that’s our old man. And Uncle Suguru. Aunt Shoko? Whoa, they look young.”

Shingo, the eldest, stood up calmly, dusting himself off. “Nice to meet you, past Dad. We’re from the future.”

Satoshi scoffed, arms crossed. “Old man still looks like a pain.”

Gojo stood, hands in his pockets, eyeing the kids. “I refuse to believe these brats are mine. No way I let some filthy woman touch me. My body, heart, soul—all belong to Sarena-chan. Not that she gets it yet…”

Ryujin and Satoshi exchanged looks of disbelief. He really doesn't see your genes in them? The women he's whipped for.

But then Gojo noticed Yukito and Shinoru—two younger kids who looked just like you. His eye twitched. No way… did Sarena have kids? With someone else?!

Shoko and Geto, already putting the pieces together.

Haruka and Yukito ran up to Gojo. “Dad!”

Gojo froze. Dad? Wait—Sarena is their mom? That means… he got her in the future?

His tone flipped instantly. “Yes! I’m your one and only dad. After all you have my Sarena-chan precious blood in your veins. Even you, brat who looks like me.”

He pointed at Satoshi. Taking Baby Shinoru from Yukito arms a complete copy of you.

Satoshi rolled his eyes. “Still don’t get how Mama ended up with you."

Suguru sighed "Really Six kids Satoru. I can see your future self giving Sarena a hard time after you finally managed to get her some how in future."
