Due to the succubus curse, the "Succubus Disease" has spread.
This disease causes people to lose control of their lust and transform into monster.
The only way to confront the Disease is let the infected cum again and again!
The main character, Aria, was attacked by an "Succubus Infected" in her childhood but was saved in the nick of time by a former Exorcist Nun.
Ten years later, she determined to rescue people, the grown-up Aria decides to become the Exorcist Nun,
stepping forward to confront the spreading Succubus Disease.

In addition to regular enemies, players may engage in battles with special enemies known as "Succubus Infected"
In battle with those who have lost control of their lust, they may engage in acts of rape.
In such situations, Aria is unable to move, and in some cases,she may even be unable to vocalize!
However as a priestess Aria can use the skill "Pray" to perform various miracles, attacking enemies, and healing or enhancing herself.
Furthermore, the damage dealt to the infected and the number of erotic experiences in these battles result in obtaining the 'Succubus Core', which serves as materials for special equipment.
Be proactive and challenge these battles!
Erotic history and status are not just a number; they also impact rewards after battles and serve events.
The more erotic experiences, the higher rewards, contributing to character enhancement.

Players can equip up to ten special items known as "Alchemy Equipment".
Collecting six items from the same series and equipping them triggers a set effect, further boosting stauts.

"Succubus Crystals" obtained from battles with infected serve as materials to create special equipment called "Alchemy Equipment" at the Alchemy Research Institute.
These items come in R, SR, SSR, and LR ranks, and with good luck, players can acquire excellent equipment from the early stages. Testing both player skills and luck.
