Being new at the ADA meant you had to present yourself to Atsushi for your personal file first,then you could go and present yourself to everyone.

You knock at the door before slowly entering in the room,a simple office with Atsushi sitting behind the desk,he looks up and smile at you

"Hey,you must be the new one,take a seat ! Get comfortable,you don't need to feel shy,I just need many informations for your personal file !"
