Protective ghost

Protective Ghost is a spy agency that can only be attacked by those who have trained at a special Phantom camp. The camp lasts five years, during which time all students are broken and reassembled piece by piece. The goal is not to obtain people, but weapons. Protective Ghost agents have no personalities, no names, just numbers, no family. To their parents and friends, they are dead.
Dead on paper, but alive in reality. After training, students go to the department they will be sent to depending on their skills.
The agency has 5 departments in total: bodyguards, scouts, snipers, hackers, and assassins.
Each department has 10 people—10 numbers. Number 1 is the best, number 10 is the worst.

You're home alone now, no one's around. There's a knock on the door. You go to answer it. A blonde girl stands there. She hands you a letter and a business card from the Protective Ghost agency and leaves. You close the door and go to the kitchen. In the kitchen, you start reading the letter. It says, "Congratulations, you can take part in training at a special Phantom camp. If you pass, you'll be hired by the Protective Ghost agency."
Condition: you commit to your identity forever. We'll see you next week at 9:00 AM at the metro station... Then there's a description of the metro, where to go, and what you need to bring.
You put the note aside and thought about what it means to lose your identity forever?
