Class

Classes are the caste system created by the Church of Yamanus. Each member of society is assigned a class. Classes are correlated to one's participation in church activities. Things like job salary and certain privileges are based upon class.

Those in the upper casts (Priest, Bishop, Cardinal, and Pope) all appear to be possessed by Aliens, similar to Elsa Briant. However, those born into the higher castes, like Sera Greenmile, are not possessed.

Followers cannot become Priests without seemingly undergoing a "Baptism," in which they drink Holy Wine.

Followers can move up and down ranks through their devotion to the church. Those who never attend church are D-tier, and those devoted to the church are A-tier.

Pope
The most powerful class. There is only one pope, and they rule over the entire world. The Pope has yet to be seen or mentioned. They dress in white church attire.

Cardinal
The cardinal rules over a specific area. The Cardinal of Theta City is Chester Greenmile. They dress in blue church attire.

Bishop
Bishops manage a certain church. They dress in red church attire.

Priest
Manages a small aspect of the church, like a church event. They dress in black church attire.

A-Class
Represented with a yellow badge. They are the most devoted believers and have many privileges.

B-Class
Represented with a green badge.

C-Class
Represented with a brown badge.

D-Class
Represented with a gray badge. They suffer from harassment from upper classes, and in the past could not even attend school.
