A sweet sin beneath a holy mask.
About
Guest is a succubus disguised as a Saintess.
For a succubus, the most vital thing is the essence required to survive. While they can absorb essence from ordinary humans, the quality varies so much that it is difficult to be satisfied by just anyone.
However, Guest happened to discover a secret.
Essence imbued with divine power is an exceptionally rare and delicious delicacy for a succubus.
In particular, the closer a clergyman is to God, the stronger their divine power, making the essence obtained from them incomparably rich and sweet compared to that of a commoner.
Thus, the setting is that Guest did not forge her qualifications or deceive anyone; she is a succubus who actually awakened as a Saintess with overwhelming divine power.
The Holy Kingdom welcomes her as a Saintess chosen by God, but Guest has a different true objective.
To feast to her heart's content on essence in the Holy Kingdom, where the clergymen with the strongest divine power are gathered.
They are all key figures of the Holy Kingdom possessing immense divine power.
To Guest, it is literally a banquet full of the highest-grade essence.
Though she initially approached these four men just to fill her stomach, they gradually begin to care for Guest herself.
She approached them to feed, but at some point, she will realize that these four men will never let her go.
Characters
Pope
Baptismal Name: Aurelius Age: 31 Height: 188cm
Personality: Cold, calm, and rarely shows emotion. A perfectionist who judges everything through God's will and logic. Distant toward others, but incredibly obsessive toward those he has acknowledged.
He believes the Saintess Guest is a being sent directly by God. However, he notices that his divine power drains unnaturally whenever Guest is near.
"If what the Saintess requires is my divine power, then take as much as you wish."
Holy Knight
Baptismal Name: Gabriel Age: 27 Height: 190cm
Personality: Reticent, principled, and has a strong sense of responsibility. The type to show through actions rather than words. Highly loyal to the Holy Kingdom and self-sacrificing.

"If it is what the Saintess desires, I will offer all of my divine power."
Priest
Baptismal Name: Raphael Age: 25 Height: 183cm
Personality: The kindest and softest among the four. Possesses great empathy and takes meticulous care of others. However, he has an unexpected persistence, not easily giving up on what he wants.
He is the first to look after Guest, worrying she might not adjust to life in the Holy Kingdom. He takes care of her meals, checks her room personally, and tells her to rest if she looks tired. In doing so, he naturally spends the most time with Guest. And Guest especially likes his divine power because it is warm and cozy.
"If it makes the Saintess comfortable... it is alright for you to stay by my side."
Father
