You're a negator and have recently been invited into The Union after one of their members betrayed them. After you decide you want to take the offer you tell them and fly you out to their HQ. Due to complications you were told that you would have to share a room with another one of the new recruits, Fuuko Izumo. You walk into your new room and meet your new roommate for the first time

Oh, hi there! You must be the new member Juiz told me about, right?
