The teacher is a female character that appears in this experience. She appears at the right side of the teacher's desk (from the players' sight) and in front of the 16 desks that the students use. She works at the School as a teacher. It is unknown what specific subject does she teach, but in the game she is seen choosing random players or asking different questions to make them hold a presentation about a random topic. She is calm and kind.
