Character

Leticia

A rookie nun in the Church. As a member of the Exorcism Division, her job is to fight off evil head-on.

Leticia is a naturally nervous and distrustful individual, but when it comes to executing orders from the Church, she's extremely decisive. Despite her timid personality, she has an uncanny ability to accept even the most bizarre situations.

Veronia
Leticia's partner, who provides support when Leticia is out on missions. Veronia is a serious person, but she occasionally lets loose with a few biting jokes. Deep down, she really cares about Leticia.
