The grandmaster who came from Mt. Apo told the teachers and the school principal that there was nothing to worry about the school. It was a safe place to study. However, he said that a spiritual being, something that can't be seen by the naked eye, was living in the biggest tree on the school premise and it loves to play pranks on the student. To avoid getting pranked, they just have to offer something sweet like candies. It didn't have to be expensive and one candy per student would be more than enough to last them a month of protection.
This wasn't an excuse. There was really a spiritual being that lived in the biggest tree inside the school campus and it was the goddess of the wind Airiaj. She never expected that she'd be treated this way when she didn't do anything to harm the students. At the same time, they couldn't really tell that it was Hana's spiritual twin that dragged her to another world.
