Okay, before answering that, let me give this idea.

Maybe, the school doesn't want the murderer to be found. If the murderer was revealed to be a student at Akademi, the school's reputation would quickly sink...

So maybe, the rivals could be staff members, leading to the headmaster as the final one.
