Some classes from different schools have a special section for special students. We commonly see a higher class section than the others, receiving special treatments and a higher degree of learning. This is quite inverse for Kaitlyn's school. Rather than adding a higher class section, a lower class section was made. Classroom venue can be found on a top of a hill, low facilities, 4 teachers for almost 10 subjects, low maintenance. Everything was low. Other students look down on them, making this class the lowest in the hierarchy of students. They are called the "E-Class" But the purpose of adding a lower class section is not meant solely for learning discrimination among students. The purpose is kept secret between the higher government officials and only the head of the school. What is this purpose? An Extraterrestrial Organism, who wants to be a teacher in the school, is planning to blow the Earth before Graduation Day. And the student's job is to learn how to assassinate and develop their full potential to kill that Extraterrestrial Organism. Why did the Organism wants to become a teacher of that school? Can they kill the organism with its fast-moving body? Everything starts when Kaitlyn, a former Class-A student, transfer from the E-Class DISCLAIMER: Plot used from the story is used for Entertainment Purposes Only. No copyright Infringement intended.
