To be honest, I have no idea. I'm trying my diddly darn best to piece together clues of who she is. My ideas are that she is either the headmaster's daughter or the final rival. It may be that the final rival is the Headmaster's Daughter.

Headmasters's Daughter: There's no proof that she is. She did state that her father won't let her attend school. Could it be that he is her father? It was never mentioned if he had any children.

Final rival: It would make the most sense for why she is not in school for a while. Rivals, however, will never know you exist. Will this rival break the rule because of all of Yandere-chan's antics, or instead she was never a rival at all? The final rival's designs were never shown, so we can no clue what she even looks like.

Headmaster's daughter is the final rival: This is the combinationof my two theories, and it makes the most sense to me with what little evidence we have.

In conclusion: It is too little to make judgements now until there is more evidence provided.
