Reality

He had debated whether to tell Gojo of the visions he had but ultimately decided against it. Only having done one mission and already having 'mental breaks' wasn't the best look. But that wasn't the case. He knew what he had seen. It wasn't a hallucination or a figment of his imagination, it was there. And it was real.

He was thankful for the sound coming from Itadori and Nobara exiting the building that broke him out him out of his thoughts, as they celebrated the completion of their first mission. As the duo made their way over to the rest of their group, a blaring noise came from Gojo's phone which he quickly took it out of his pocket and scrunched his face up in disgust after reading the contact name. Taking the phone to his ear, Gojo's listened quietly to the person on the other end of the phone before nodding and ending the call as soon as possible.

"Aizen, you have a mission. The higher-ups need a grade 1 sorcerer for it apparently but anyways you have to wait here as a driver is coming to take you to the location of the mission." He said as he turned to Aizen, his tone heavy with annoyance. Turning back to the rest of the first years, he told them that they needed to go back to Jujutsu Tech. With that and quick goodbyes, Aizen was left alone with only thoughts to accompany him in his solitude.

Wind tickled his face in a gentle way and brushed through his golden hair. Looking around, he took the time to think through how he would go about things from this point on as the canon had finally started.

At first, he had thought it a bad idea to intercept with the mission that 'killed' Itadori but then he was reminded. Reminded that the canon events weren't going as planned as Sukuna as of this point is supposed to be at two fingers but he is at three. Secondly, Megumi never ended up injured in the original story which frightened him. To think that his knowledge of this world was unreliable. And the only way to deal with that gap in knowledge that he relied on so closely is to gain an edge, and that edge was in power. He needed to understand his technique first.

Straying him away from his thoughts was another attack from the violent wind that punched against his face. In frustration, he turned the other way and was now facing the same building that Nobara and Itadori had completed their mission in but it looked different. Rather than being rundown, it looked to be decaying and melting. In a stupor, he arose from his seated position and steadily approached with his hand placed tightly on the hilt of his sword.

Suddenly, the grey clouds started to darken and lightning tickled the clouds.

'Weather doesn't change that fast.' He internally noted.

Rain started to pour like bullets wounding the concrete floor and the wind regained it's strength.

'What the hell. I need to get out of here.' Just as he was about to slow time and speed out of the vicinity, he picked up a disturbance from behind him. With a rapid spin he locked eyes onto an obscure figure into the distance but in that exact instant waves of murderous intent came crashing down onto his shoulders. It was only then he had noticed the black crows in the distance soaring and circling the figure in a ritualistic type of way.

His body wanted to still in fear but his resolve fought against it and he sped towards the figure with cursed energy enhancing his feet and his blade. Blitzing through the wind, he felt no resistance from the wind that worked against him as he charged towards the silhouette. He looked towards his sword that held a purple tint and saw how the wind parted when it made contact with it, like a hot knife cutting butter.

Im a fraction of a second, he reached his target and sliced through the shadowed person, only to cut through nothing. Eyes widening, he quickly glanced around his surroundings to find himself back in his prior position, sitting against the wall. The weather no longer was in a chaotic state and had reduced to only the waves of the wind.

'Something's trying to play with my mind. I'm sure of it. Everything I saw, from the weather to the outline of that person, it was all so real. And then it disappeared like it was nothing. Merely a vision….' A black car appearing in the distance stopped his train if thought for a second. 'Or maybe an illusion.'

"Gojo-Sensei how comes Kusakabe was personally requested for a mission on his own?" A young female voice spoke belonging to a girl with ginger hair cut at shoulder length.

"Because he's a special case. You guys should get used to this now better than later." The white haired man responded, a smile gracing his pink lips.

"And why's that?" Megumi was curious as to why his friend would be requested for many missions.

"Because he's a grade 1 sorcerer." Nobara and Megumi eyes widened in surprise whilst Itadori held a confused expression on his face, asking himself what's a 'Grade 1'. "He'll rarely ever be on missions with the three of you due to the higher ups already taking an interest in him. From now, think of him like those cousins you see once-every month rather than an actual classmate because his attendance will definitely be rare."

"He certainly does seem strong." Itadori inputted. Though he didn't know much of Aizen, he knew that the boy possessed strength that far surpassed his own and he could tell that by just the way he stood. "Anyways, so where are we going right now?"

"To celebrate with some pizza." The trio, mainly Itadori and Nobara burst into cheers before Gojo muttered a little," and some fingers."
