[OP: ]
There are twelve main homeroom classrooms in the great academy each being big enough to fit nearly four hundred and fifty students at a time and that's just the homeroom classes.
The academy has many places that could hold thousands of people at a time and thanks to the spatial expansion magic, many places have the capacity to hold tens of thousands of people at a time in the inner area of the academy.
But, the twelve homerooms are the places where the students start each of their days, and that is also the place where they take their first compulsory class from their homeroom teachers.
