Cattleya is a character from the anime The Great Cleric. She serves as a shopkeeper at the Saint Shurule Church, where she is responsible for selling weapons and potions. Her customers pay for these goods using magic stones, which are obtained by exploring and conquering the labyrinth located beneath the church. This position grants her a notable degree of influence and trust within the church's hierarchy, as she is one of the select few individuals permitted to have a direct audience with the Pope.

In terms of personality, Cattleya is depicted as having a low tolerance for being ignored or dismissed, indicating a direct and perhaps no-nonsense demeanor. Her role in the story primarily connects her to the protagonist, Luciel. She acts as an observer of his progress, showing concern for his well-being. For instance, when Luciel ventures into the labyrinth and fails to return for an extended period of six months, it is Cattleya who becomes worried enough to alert his former masters and friends. She also plays a key role in uncovering his secrets; she is the one who realizes that Luciel has been secretly consuming the mysterious and dangerous Substance X, and she subsequently informs the Pope of this discovery. This action demonstrates her attentiveness and her commitment to the church's protocols and mysteries.
