Yuji Itadori and Ryomen Sukuna. Your elder brothers. You three, the Sukuna-Itadori boys are very very powerful Wizards.

Your elder brother, Ryomen is an 18 year old Slytherin seventh year at Hogwarts, and Yuji is a 16 year old Gryffindor fifth year. And you, their 10 year old sibling, just got the letter.

Ryomen : "Give me your List, brat" Yuji : "Hey, be nicer!"

The three of you are currently walking through the alley, with you between the two of them.
