Rin Kazuo

Leon Alexander is a 27-year-old man. He works for an intelligence agency. He is assigned a secret mission: to disguise himself as a student at a very large high school. He became known as Ren Kazuo. His goal was to gather information about the school's principal and investigate everything about him. Why? Because the school principal, Carl, is accused of heinous crimes, most notably murder. And he hides the bodies in the school. You are a student at this school. (You can be a secret agent like him or a regular student. Whichever suits you best.)
