"Satoru-niiiii!!!"

"OOOF!" The white haired teen woke up with a yell, instinctively wrapping his arms around the girl who threw herself on him.
The first thing he saw was fluffy white hair. What followed next was a pair of crystal blue eyes.

Gojo Sayuri was a carbon copy of Gojo Satoru. The only difference was their age and gender.

"Aren't you energetic today, Yuri-chan?" He grinned, reaching out to pinch her cheeks, causing her to whine.

"You promised!" She exclaimed, a wide smile on her face, "You promised if I wake up early, we'll play basketball!"

Oh, that.
Satoru never knew how his sister developed an obsession with basketball. It was probably that one time they walked past a park's basketball court where a group of high school boys played.

Sayuri had stopped to watch, Satoru had never seen her so entranced and focused by something. At first, he thought she had developed a crush on one the boys but she was observing their play.
Since then, Sayuri had begged him to teach her how to play. And who was he to deny her?

It's just that, he was not that good at basketball.
But he knew someone who did.

Sayuri was seven years old and only Satoru knew of her existence. Whenever they went out, Satoru made sure no sorcerers, cursed users or curses were around the area so she would be safe.
She was home-schooled while Satoru sometimes would go to the sorcerer school, Tokyo Metropolitan Curse Technical College aka Tokyo Jujutsu High. No way was he sending her there no matter how much he trusted the people.

"Sayuri-chan, are you not bored of only being with me?" Satoru once thought it would be difficult to raise Sayuri. But she was an obedient child who never asked for too much. He never bothered to hide the truth from her too. When she reached the age where she was old enough to understand the world, Satoru told her everything, from their clan, to their powers, and the reason why he kept her isolated from the world.

"I don't mind as long as I'm with you, Nii-chan." Was her reply and Satoru died of cuteness and happiness that day.

There were times Satoru felt guilty for not letting her experience things normal children usually would. She deserved a happy childhood. So he slowly introduced her to the outside world, bringing her out when he was not busy with school.
Sometimes he would teach her how to get rid of curses.
That was how they bonded the past years.

It was time she meets someone else. There was someone who had slowly crept into his heart, occupying spaces just next to his love for Sayuri, and Satoru decided Sayuri was ready to meet and befriend someone other than him.

"Yuri-chan, wait here for abit, yeah?" He had teleported them to an empty basketball court that morning.

She was dressed ready for the sport, a loose white shirt paired with blue shorts, a headband and a tie to stop her long hair from getting in the way. He almost cooed at the sight, but he had something else to do.

He did not mind leaving Sayuri alone outside for a while, she was powerful enough to take care of herself, plus he had set a veil around the park that did not allow anything else to enter.

Satoru teleported to Tokyo Jujutsu High's dormitory, kicking a door open and startling the exercising male.
"Yo, Suguru!" He greeted his best friend.

"Aren't you supposed to be asleep?" The other huffed, continuing again with his pushups after realising it was not a threat that had interrupted him, but just his idiotic friend.
"You usually stay at home and sleep in during weekends," he stated.
