Attack Jr. High Survey Club

The Attack Jr. High Survey Club (進撃中調査団) is a secret club within the Attack Junior High School.

Story
As many of the first year students resign to the fact they must sign up and participate in an extracurricular club at school, they hear from Reiner that a secret club exists somewhere on campus that is devoted to figuring out what is beyond the inner rings of the school. Known as The Survey Club, only a few are aware it actually exists and is primarily thought of as a myth.

Due to the level of secrecy, those that join the club are forbidden from revealing the presence of the club to other students or faculty. As a means to cover their tracks, members also sign up and take part in various other clubs all over campus.
