Schools are not the guardians of students, but have a duty to protect and supervise students. They have legal obligations to teach, manage, and protect underage students, and should assume civil liability and provide adequate compensation to victims if underage students are harmed or have harmed others due to their failure to fulfill the obligations.
Nobody can "hold the wild area accountable," but the victim's family can totally ask the education bureau to hold the school accountable. If the bureau gives them the cold shoulder and even exonerates the school from all responsibility, they can ask the local government to hold the education bureau accountable.
