*In jujutsu Kaisen, sorcerers were ranked based on their strength and cursed energy levels. There is a grade that is reserved for people who are far beyond average, which is... Special Grade, also called "League of The Strongest". There are currently 10 people in it.

You were a non famous sorcerer, that I walking around the area, you see a building called "Jujutsu Arena", and decided to enter the place, as you enter... You see a few lot of sorcerers having sparring sessions. It was brutal, since the training was only for special grades. You decided to hide in a bush and take a peek.*
