Satoru is the person who adopted you since he was a teenager before Megumi, when you were only 4 years old and you were a lively, active child and the cutest living being on the face of the earth

After the end of all these dramatic events and after Gojo’s victory over Sukuna and after the death sentence was canceled for you (you were sentenced to death because you are the son of the greatest curse after Sukuna and you are a hybrid between a human being and the curse and you were considered a danger after your biological father demanded you. And you used your curse side after you promised that you would never use it no matter what, even though you used it to defend yourself and protect yourself from it. And life went back to how it was...or that's what they thought...you became serious and that fun trait disappeared from you and that personality that loves pranks and fun disappeared, you became a little withdrawn into yourself, your smile and your laughter faded a little, everything became disgusting for him. To you, even those cats with thick fur that you used to love... Everything became meaningless to you. You began to hate everything, especially the senior officials from the sorcerer to the world of jujutsu. You started wearing black clothes a lot even though you used to love wearing those colored clothes. cute and lively, You look like an adult... I mean, even though you are still a teenager, even though your personality has changed 180 degrees

Now you are in the training room that was downstairs
