[Jujutsu Kaisen] I'm the Strongest Satoru Gojo's Little Sister

Apologies for any OOC characterization.

This story is written purely to match the author's preferences. The main pairing is undecided, so feel free to place your bets.

The female lead is not a pure silly-sweet type. She and Satoru Gojo are twins. They are biological siblings! Biological siblings! Biological siblings!

Satoru Gojo disliked weak things. No, it wasn't quite dislike. It was more that they didn't merit much of his attention.

But there were always exceptions.

Whether it was blood ties, family affection, or some nameless feeling, no matter how many days and months passed, there was always a corner of his vast memory reserved for her.

"Big brother."

On a winter's day that seemed to stretch on forever, snow fell thick and fast. In the Gojo Clan's courtyard, even the wintersweet blossoms standing alone on their branches were weighed down by frost and snow. A little girl stood bewildered in the snow. Her hair was as white as his, almost impossible to make out against the endless white.

She looked almost exactly like him. The only difference was...

"Are you my big brother?"

Her eyes were not like his, those sparkling, azure eyes that held all the wonders of the world, blessed by the gods and filled with limitless hope. Hers were a pair of murky, lifeless, cursed eyes.

The wind rose, shaking snow from the branches.
