Scissor X Pencil X Pen

The utensils in school have only one purpose: serving their owners. But when Scissor learns that utensils are thrown away after being used, he rebels against his pencil case. His pencil case has always known about the reality of the world and they send out their assassin, Pencil, to hunt down and eliminate Scissor before he can bring chaos to the classroom through his rebellion. Will Scissor be able to free the utensils of his classroom, or is he just a "naive, young utensil"?
