I haven't met the teacher yet after roaming floor 45 and 46. I searched part of 47 and still haven't seen her.i think you just got new mission after meet ponytail girl , after that go to deeper new dungeon (45) and you will meet teacher
Edit: Nevermind. I found her two floors down on the far NE end of the floor.
Edit 2: How do you unlock floor 48? If I recall, You can't simply defeat the boss on the 47th floor, but remove the "seal" on it. but with what again?
