Katsuo turned and saw a man dressed in black with a cheeky grin on his face, floating in the air.

He was tall, had spiked-up white hair, and had a white bandage blindfolding his eyes.

'Gojo Satoru!!'

There was no doubt in Katsuo's mind anymore, his early theory about an existing organization was correct, and the universe he was in was indeed Jujutsu Kaisen.

"So? Cat got your tongue?"

"... Tetsuo Katsuo."

"Oh, Katsu-chan then. I have to say, you are very powerful, at your age I wasn't as impressive as you, the way you broke through its domain expansion with a [Black Flash] from the inside was very cool, not many people can do the same."

Katsuo continued to look at Gojo, if he didn't watch the anime he wouldn't know what Gojo was talking about, so he didn't know what to say without sounding suspicious, but he didn´t need to say anything because Gojo continued.

"Ah, I still haven't introduced myself, have I? My name is Gojo Satoru, 23 years old, a sorcerer like you, I'm from the Gojo Clan. I haven´t heard about the Tetsuo Clan before, do you belong to any clan?"

Katsuo shook his head.

"You don´t belong to any clan? Then how did you become so powerful?"

"Self-study and training."

Gojo remained silent for a moment before chuckling, he could tell that the kid in front of him wasn't lying.

"Self-study and training? That's hilarious! Hey, Katsu-chan, do you want me to trai..." *BZZ BZZ*

Gojo took his phone from his pocket.

"Hmm, just a second, katsu-chan. Moshi, moshi"

Katsuo took this time to calm down, he could feel the fatigue caused by the fight, if there was a bed in front of him, he would be snoring in it, but now there's something more important to think about.

Gojo Satoru, the most powerful sorcerer of the jujutsu society, was in front of Kastuo and if he wasn't wrong, Gojo was going to ask if he could train him and, of course, he wanted that even though the Gojo Satoru in front of him was a stranger. If he was anything like the Gojo Satoru from the anime then he could be trusted, and from what he has seen until now they are very similar.

However, he has a family. His mother, father, and four-year-old sister were waiting for him at home, and now, more than ever, he didn't want them to leave his sight. This world was dangerous but he has been treating it too lightly because he hasn't had a real challenge until now.

He really wanted to be trained by Gojo, but he didn't want to be away from his family, so it seems he would have to refuse.

Gojo Satoru POV

Today has been full of surprises.

I was resting when I received a mission to exterminate a special grade curse that has seems to be responsible for the disappearance of shikigamis sent to a city for quite some time, an easy mission like always.

Using [Limitless], I teleported to the highest perch of the city where I was supposed to find it and lifted the corner of my blindfold, to increase the amount of information received by the [Six Eyes] and immediately noticed the domain expansion used in an alley, it was still primitive but showed that the curse had already taken the first steps to become a true menace to society.

But I also saw a kid, around 13 years old (Katsuo is tall for his age), next to it, the kid had an absurd amount of cursed energy, almost half of mine, but I wasn't familiar with him and I knew almost every descendant of jujutsu society clans.

I saw as he ignorantly entered the curse's domain expansion and was going to help him when I saw him enter a battle-ready state after he noticed the curse and the pile of corpses, a thing every sorcerer has to get used to because we have to know that we can't save everyone.

Then I saw his battle against the curse, and the more I saw the more interested I became.

Those mysterious pills, his unstoppable fighting spirit, high physical strength, expertise in martial arts, and splendid cursed energy manipulation.

I had to admit, at his age, without using [Limitless], I couldn't do as well as he did.

Then when he shattered the domain expansion with a [Black Flash] and, probably using his innate technique, turned the special grade curse into a pill, I knew I wanted to talk with him and so I did.

Man, what a surprise it was, he trained himself to such a degree, it's actually scary, it seems that we are indeed in the golden age of jujutsu, if nothing happens, he can become almost as powerful as me, now that's exciting.

(AN: Gojo has very high pride and arrogance, doesn't he? But that's natural, as he is the epitome of Jujutsu)

I was about to ask if he wanted to be my student when I received a call.

They needed me for another mission, and I don't really want to go, after all, there's nothing more exciting than what is in front of me but they seemed to be panicking so it's probably important.

I looked at the absent-minded kid, most likely tired from the battle.

"Hmm, Katsu-chan, I need to go but I need to ask a question first. Do you want me to train you?"

The quiet kid looked at me before lightly bowing his head.

Gojo Satoru POV ended

Katsuo heard the question that he was waiting for and gave the answer he thought of.

"Gojo-san, I don't really know who you are but you seem honest and strong, at least stronger than me, so I would like to be trained by you but I don't want to separate from my family, so I will have to decline"

Gojo made a surprised face before smiling.

"I think you're misunderstanding something, you don't really have to separate from them. I'm always very busy so I can only give you lessons from time to time, so you only need to give me your address and I will drop by when I can."

Katsu understood the misunderstanding, he thought he would have to go with Gojo but it seems that he was thinking too much, the anime poisoned his reasoning, but he still frowned a little, how could he explain a strange man appearing by the house to, supposedly, teach him.

"Giving my address is a bit..."

Gojo stared at his face and "understood".

'Silly me, how could a teenager give a person he just met his home address, not that it's hard for me to figure it out.'

Katsuo looked at Gojo and nodded.

"Katsu-chan, how about we meet at the park? Every Friday at this hour, go see if I'm there."

"Alright Gojo-san, thank you very much"

'I can work with that'

Thought Katsuo.

"It's a promise, I have to go now, bye~"

Said Gojo while waving and teleporting.

Katsuo looked at the spot where Gojo formerly was and then looked at his bloodied clothes slashed in strips.

He thought for a while.

'Should I inform my family about this? My parents deserve to know. I'm determined to continue my curse hunting life and I don't want to lie or hide it any longer, not to mention it would be easier to do things if they know.'

Katsuo took a deep breath and started hopping through the rooftops, to return home away from the public eye while contemplating about his life and what he wants his future to be.
