It's someone in the CLASS. It doesn't necessarily have to be a student. Mei's sister died before Kouichi was in the class (in April), so there HAD to have been an "extra" one before he showed up. Plus they mentioned they had JUST enough desks before he showed up, no mention of needing an extra desk. It can be a teacher because she used to be a student, and she died 15 years ago.
