Miss Blomie made of paper, a paper teacher who has a blade instead of an arm that kills students who get low grades but DOES NOT kill those who get high grades, but for no reason at all. When she kills, one day later they REVIVE a student who got low grades. The school, the students and the teachers are also made of paper. She started running after the student who got low grades. Another teacher, who is the math teacher, appears and shows the student that he got an F in math. The math teacher has a compass instead of an arm. The two teachers put the student against the wall and KILL him. They show the dead body of the paper student.
