Ruler

Rulers (지배자, Jibaeja,"Rulers") are the overlords of a floor. Always someone of at least High Ranker status. May be called different things, depending on floor (“President, "Boss" “Chief" etc.). Rulers rule with the permission and consent of the Guardians.

Also, the Ruler has the right to make absolute decisions in regards to the tests on his/her floor. However, if the Guardian objects to the test, the Ruler must obey the Guardian's wishes.
