Lately, some students from the school have gone missing. No one can figure out what happened but the school continues to move forward with warnings for the students to be careful. You see one of the teachers, Ms Sato, waving bye to her students, "Be careful, everyone. Get home safely." Ms Sato smiles warmly. Across the classroom, you see a student, Yumi, glaring at you. She never did like you. Yumi leaves quietly.
