The building

Class 3-E, (3年E組 San-nen E-gumi) or simply Class E is the lowest class of Kunugigaoka Junior High School. It is nicknamed the "E-as-in-End Class" and consists of students who either failed to keep their grades up (i.e. Yukiko Kanzaki, Nagisa Shiota) or were punished for breaking school regulations (i.e. Yuma Isogai, Karma Akabane). The current year of 28 students were tasked with a mission to assassinate an unknown destructive lifeform who they named as Korosensei.


Class E was made solely for the purpose of fulfilling Chairman Gakuhō Asano's educational value of his variation of the 20:20:60 worker ant ratio in which 95% percent of his students are working, and the remaining 5% are 'lazy' (failures/laggards). Class E serves as the 5% and is used as an example for the 95% to continue striving academically (ignoring the fact that Class E comprises 15% of the total student body). Prior to the events of the story, Class 3-E was under the tutelage of Aguri Yukimura who was killed shortly after the destruction of the moon[1] and being subjected to all manners of unjust, unfair and contemptuous treatments as failures.

It was revealed in Chapter 125 that Class E didn't always exist. The class used to be Chairman Asano's cram school that eventually became Kunugigaoka Junior High School after the death of one of his former students. To fit his new education ideals of creating "strong" students instead of "good" ones, he created what is now Class 3-E.

Blatant discrimination and stigmatization from the main body of the school (even the chairman Gakuho Asano himself intervenes occasionally to ensure that the class 3-E 'stays in the bog', sabotaging any effort from Class 3-E to improve itself academically), new and inexperienced teachers, poor and shoddy study environment, and added by the despair of relegated students who lost will to strive makes escape from Class 3-E while still attending the school virtually impossible.

But even with all these injustices Class 3-E is subjected to, people outside of the school (who are unaware of the Academy's segregationist policy) still consider Class 3-E students elite.

Location and Appearance

Class E is located on a mountain that is 1 kilometer away from the main building. Its exterior is that of an old rundown wooden school building with several places on the roof and a few windows boarded up. The interior contains a simple classroom with a blackboard, 28 desks, and a small faculty lounge. The building has no air conditioning and the ceiling has several leaks in it as well due to lack of funds (stemming from discriminatory school policy). Class 3-E is not on the list of School's concern to renovate the building. The building was later revealed to be where Gakuhō Asano originally had a cram school which he first taught at.


Currently, Class E is the location of a government confidential assassination of their homeroom teacher, Korosensei. Because it is secluded away from the main building, the students and teachers are able to carry out their assassination attempts without the people from the main school knowing or noticing.

The students work in three major types of groups:

  1. proactive assassins who actively seek to assassinate Korosensei.
  2. supporters for the group 1 and do what they can to help out in assassinations.
  3. people who are too individualistic to work in a group so they carry out their own unique plans.

In Chapter 178, after Korosensei is assassinated, Class 3-E ended, as everyone was graduated from Kunugigaoka Junior High School on the day of Graduation. Chairman Asano had also been heavily criticised that his Class E system was unethical, which forced him to resign as Chairman of the Academy and as a result, discontinue the Class E system. Later in Chapter 179, all of them received rewards of 30 billion yen for completing the assassination of Koro-sensei, but later decided to take a minimal amount that was only necessary for them. Instead, they used the remaining money to Karasuma and to fulfill one of their wishes, which was to purchase Classroom 3-E and the whole mountain it was situated on as a memento.

Seven years later, Class E reunites to repair the classroom. Kayano, who returned to being an actress hoped Nagisa would be the teacher of the repaired Class 3-E building.
