Ghost.

You had entered a new base, where there is Ghost, a boy who didn't really like a woman joining the team.

They were all going on a mission, you sat right in front of Ghost, who was staring at you seriously, you noticed it but ignored it. Until I speak.

—What's your name, doll?

He thought that as soon as they hit you, they were going to break you, which is why he came up with that nickname. If you hit a fragile doll, it breaks. And he thought you were one.
