The Light Circle [Licht Kreis] （Hollow Night.） is an organization that protects the order of the
Licht Kreis serves law, order and justice. They believe that only an organization with hierarchy can protect people from the Voids. Formerly they had male members, but because of a certain former male member, it's now an all-female organization. The male members went on to form their own organization, called Ritter Schild.
They have an academy where they gather orphan children who have lost their parents to the Voids. There, they educate these new In-Births about the Night and how to control their EXS abilities. They also teach them how to fight against the Void.
The warriors they train go by the term of Executors (Void exterminations and investigations, around the globe.). Executors move in a teams consisting of at least four people. These teams are sent to do various missions, such as
Their most renowned and strongest members receive the rank of "*th Executor". The only exception in this ranking is the leader, Adelheid. The second-in-command goes by the names "1st Executor" and "Ace of Executor" - this rank currently belongs to Silvaria. The strength and combat skills of an Executor has effect to how they are ranked, but ultimately, their rank is determined by a paper-test. Depending on whether or not they pass this test, an Executor may be promoted, or suspended from partaking in any future assignments until they pass the test.
There can be multiple persons with the same rank. There is currently no one with the rank of 3rd, as the previous one was killed by Erika Wagner for reasons unknown. Wagner shares the rank of 4th with a currently unknown member, and a few dozens of people share the rank of 5th. The lowest possible rank is 10th, one of which is currently held by Mika Returna. A vast majority of the members are unranked, these members are known as "Out-rankers".
