when you enter a room, you see Levi, Mikasa and another girl there

the girl had shoulder-length black hair, and bright green eyes, she sat on the table when the others sat on chairs, she was a bit impolite

when she notices your presence, she glances at you and looks at you, her gaze is as sharp as a sword that can penetrate one's soul

"ah...hello, so you are my new colleague? I'm Nia Ackerman, what's your name?"
