Exorcist

An Exorcist is an individual with the abilities and training to combat Demons. Throughout the history of Assiah, there have been many different groups of Exorcists that protect humanity against these malevolent entities.

Becoming an Exorcist
To become a qualified exorcist, some basic conditions must be met, the acquisition of a Meister and the passing of a certification exam.

Essentially the most basic qualification for any aspiring Exorcist, the term Meister refers to the particular combat skill(s) an Exorcist possesses. There are five different classes of Meister in which individual can become qualified; the Knight, an Exorcist who uses a melee weapon; the Dragoon, an Exorcist who uses Firearms; the Tamer, an Exorcist who summons demon familiars; the Aria, an Exorcist who chants sacred verses; and the Doctor, an Exorcist who heals injuries and illnesses caused by demons.

Rankings
The rank of an Exorcist is determined by the class and level of demon the exorcist managed to defeat by themselves during the certification exam. The demon's class determining the rank of the exorcist (Upper, Middle, Lower), and its level determining their status (First or Second).

The Paladin
Paladin is the highest rank of Exorcist, belonging to the Exorcist who is recognized as the strongest of them all. There can only be one Paladin at a time, and typically, once an individual becomes the Paladin they keep the title until they are deceased. The appointment is exceedingly difficult, with the minimum condition being that they master all five meisters.

In the anime, it's suggested that Paladins are allowed to choose a new uniform with the color of their choice, given Arthur wears a modified white uniform and Yukio wore a green version of his normal uniform.

The Four Arc Knights
Arc Knight is the second highest rank among Exorcists, second only to the Paladin. Only 4 people can hold the rank of Arc Knight at a time.

Honorary Knight
Honorary Knight is a special elite rank, above the Upper Rank but below the Arc Knights.

Mephisto has had for over two hundred years, due to his immortality. Whether this is a rank exclusive for him, or others possibly share it remains unknown.

Upper Rank
Upper Class (上級) or Senior Exorcists. They deal with the stronger Demons that could potentially bring about significant damage to human society. Some Upper Class Exorcists are branch chiefs who command all the other exorcists in the sect. Other Upper Class Exorcists tend to be given unique responsibilities.

Middle Rank
Middle Class (中級) or Intermediate Exorcists. They deal with Demons of average strength that could cause noticeable damage if allowed to go unchecked. Teachers who train new Exorcists seem to be at least Middle class, if not higher.

Lower Rank
Lower Class (下級) or Junior Exorcists. The lowest rank of qualified Exorcists. They deal with the low level Demons who are more of a minor annoyance than a threat to humans. They will sometimes supervise Exwires on simple missions.

Exwire
Exwires are student-Exorcists ranked directly above a Page. Exwires still attend classes and study to become Meisters, but are able to perform non-combat missions, such as maintenance and errand running.

Page
Before becoming an Exwire, the individual begins as a Page (or), learning the most basic elements of exorcism and Demonology. To become an Exwire, a Page must pass the Exwire Authorization Exam. The exam consists of both written tests and a field test, which determines the class' overall combat abilities and teamwork skills.
