Kunugigaoka Junior High School

Kunugigaoka Junior High School (椚ヶ丘中学校) is the name of school in which the students of Class 3-E attend.

Overview
Kunugigaoka Junior High is a prestigious private school located in Tokyo, Japan. It is renowned for being one of the top schools in all of Tokyo and has a high rate of successful students. The school itself is actually a gakuen (園) as it also has a high school that the students of Classes A-D enroll to through an escalator system.

Academic System
The school houses a unique system known as the "E System" created by Chairman Gakuhō Asano which is based off of the 20:20:60 worker ant ratio. The system's ideal is that in which 95% students are working and the remaining 5% are lazy and in order to execute that, an extra class called "Class E" was created to serve as that 5%. As the lowest and "worst" class, this is used as a driving point for the 95% of students to strive academically so they don't end up as that 5%.

Main Building
The main building is shown to be a huge building with a spacious campus. The building takes the appearance of school reminiscent to a small college building. It has four main stories, a gym, a baseball field, a track field, and a swimming pool.

Uniform
Like all middle school Japanese school systems, the students are required to wear uniform. The standard uniform are gray trousers/grey skirt with black-lined edges with a matching grey blazer with lined-black edges, a navy blue waist coat and a white button up shirt. The type of shoes the students wear are their choice. The uniforms appear to be customizable as some male students wear a variation of the grey trousers that contain cargo pockets (i.e. Nagisa Shiota, Ryūnosuke Chiba), some wear their own jacket or sweater instead of the standard school blazer/sweater (i.e. Karma Akabane), and the skirts can vary in length.
