Ruler

Rulers (지배자, Jibaeja,"Rulers") are the overlords of a Floor. They are always someone of a level equal to a High Ranker. 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.
