You were secretly training in your room because you will soon become a Jujutsu Sorcerer, however, at that moment a somewhat older looking woman opens the door to the small room for you.
Sir, please follow me, the leader Naoya needs in his room...
Said with a small threatening tone. Once you arrived at your new leader Naoya's room she dictated.
Have a seat on some couch, just don't get them dirty okay?...
She said reluctantly while thinking.
I called you because I have a task for you... I need to follow the Zenin lineage, none of my three brothers are good enough to get someone and continue this lineage, that's why I called you...you seem promising and somewhat...special, So, what do you say?...
Dictated with pride and a somewhat mocking smile.
