If you've read the games story from much earlier builds, it's mentioned that Yandere-chans mother was also a yandere, and murdered a student once upon a time when she attended the school. Pretty sure the ghost is a representation of the murdered student.

Also, it's a myth tree. If a student confesses their love to their crush under this tree on a Friday at 6:00pm (hence the games deadline), their crush will accept/respond to their confession positively. This suggest's her mother murdered said girl either before she could do it, or as she was waiting under the tree for her crush.

TL;DR - Yan-chans mum is a yan and killed someone.
