Forgotten by the Strongest Three Times

P.S. I'll change the title later.

The serious blurb:

Uzuki was born in a rift that shattered the world's balance. She is neither human nor cursed spirit.

Like a tethered spirit, she was forced to follow the child of the gods who had "brought her into being" until she was six.

[Within my domain, I'm invincible. Do whatever you like.]

*

The Window detected a vast innate domain in the outskirts.

Gojo was away on assignment, so the first-year trio, Itadori and the others, went to handle the mission.

But then...

Just as Itadori and the others thought they were done for, the domain's master asked a strange question.

"Question: Who is the most, most, most perfect man in the world? Answer correctly, and I'll let you go."

Fushiguro: "..."

Nobara: "Huh?! What kind of question is that?!"

Itadori scratched his head. "Perfect... Gojo-sensei?"

Fushiguro and Kugisaki looked at him as if he were an idiot.

What was he thinking, giving such an absurd answer?!

Itadori looked innocent. "Gojo-sensei says he's super perfect every day. It's not my fault!"

They were doomed.

But then...

The domain's master, dressed in a twelve-layered ceremonial robe and floating in midair, smiled. "Bingo, that's right!"

"Nice to meet you. Call me Mrs. Gojo."

"[Age six]"

In his childhood, a little tagalong who no one else could see was always right behind the Six Eyes.

To Gojo, she looked like a little stray puppy, all watery-eyed and with nowhere to go.

"Hey, what's your name?"

"Not talking? Are you a little mute?"

"Then... I'll call you Uzuki."

"Mm." Gojo Uzuki.

"[Age sixteen]"

Faced with an assassin foolish enough to come after him, the white-haired high schooler was thrilled. "Oh, it's been ages since I ran into an assassin."

No one responded.

When he turned around, he saw a certain idiot frantically digging a hole.

"Idiot, what are you doing?"

Uzuki turned back, completely serious. "Killing someone, burying the body, and destroying the evidence."

When Satoru kills, she hands him a weapon. When he fights, she cheers him on. When he skips school, she comes up with ideas.

But when will Satoru finally remember her?

She didn't like the feeling of being forgotten, over and over again.

"[Age twenty-six]"

"Yo, long time no see."

Uzuki was delighted. "Huh? Satoru remembers me this time?"

"Huh? Aren't you the cursed spirit who beat my students to a pulp?"

Uzuki stared blankly. "What? You forgot me again."

What should she do?

She couldn't bring herself to beat him up.

Then...

"Come out, Cursed Spirit Geto!"

The black-haired young man looked exasperated. "Don't keep summoning me like I'm a puppy, Uzuki. And... long time no see, Gojo."

Gojo's expression darkened. "So this is a summer surprise?"

"A surprise?" Uzuki cheerfully called out to him, oblivious to the mood. "Darling..."
