[GM4A] [LFG] [Custom] The Ruby Knight

One name sparks a wave of emotions when their name is uttered. Whether it be fear in the hearts of villains or hope in the innocent, the name is the same: the Ruby Nightmare. Each country in the land of Arclent has their own system for dealing with the demonic portals - but when needs must, Agnes Flarebyte of Ardoheim is dispatched to the crisis - alone.

And she is always, ALWAYS, successful. So what ever could she need your help for?

You receive a few knocks on your door. At this hour it could only be Agnes, yet you almost sense that something is wrong. The lighter, slower knocks... Perhaps it is simply something else, yet you look to your weapon regardless.
"Come in." You declare, trying to stay as neutral as possible.
The figure of Agnes appears in the open doorway. You ease up only ever so slightly, until your eyes meet the trail of blood across her body. Is she hurt?? No, you've never known her to be hurt. So the blood must be-
"I've killed the prime minister."
Agnes states plainly, answering your inner monologue. Your mind immediately races to how you can assist, with thoughts of treason or whether or not you were next never even entering your mind. Agnes was the highest paragon of justice, which is why you endlessly looked up to her. You were ready to listen for her orders.
"He attempted to draw me into some type of ploy. My mana has been drastically drained from my body, and doubtlessly he took to his grave the method of getting it back. I did get one hint before he died, however. Some demonic magic was used to turn me into a succubus of sorts. At least, that was the attempt. But he implied that sexual desire would help me refill my mana, and I am inclined to believe him, based on what he was feeling before I died. You will hide the body, and then draft plans to increase sexual desire around me. I will clean myself. Goodnight."
The door closes, leaving you momentarily bewildered - but resolved to complete this odd, yet monumental task.

=========================================================

Hello! Hope you liked my little summary/introduction. Before I get into the full prompt, I'd like to say that the "A" part of "GM4A" is that I could be convinced to let you take the reins of Agnes if you are so inclined. Now, for the prompt specifically:

Agnes Flarebyte holds the lofty title of demon annihilator, a soldier of the crown sworn to defend the country from rifts that spawn dangerous demon en masse. So powerful is she, that the favor of lending her out to support other countries holds significant political sway. While seemingly mostly devoid of emotion, Agnes has shown herself to be a great paragon of justice. For this reason, you look up to her endlessly, and are grateful to be her chief advisor.
After going through some of the details of the succubus curse that's afflicting her, you discern a few things:
For one, this is extraordinarily powerful magic. An ordinary person would've crumbled and transformed into a succubus. Agnes can hear the thoughts of desires that are centered around her, and any sexual acts towards her restores her power by a tiny amount. You need to devise ways to get as much sexual desire projected onto her as possible, and you have to get her to agree to do it. Naturally, all of this has to be done discreetly.
To gamify this a bit, Agnes will have stats such as sexual appeal, sexual knowledge, agreeability, all of which is to be improved over the course of the rp. Whether or not she "succeeds" at certain proposals you give her will be based on these stats. Agnes is too strong of character to become "corrupted" necessarily, but she will change given time.
Speaking plainly in sex terms, Agnes could be convinced to let herself get taken advantage of in an alley, work in a brothel, prowl the slums, turn the charm on her soldier subordinates, and anything else of the like you think would be hot.

If you're interested and would like any other details, feel free to message me. This will take place over discord, so I expect for you to eventually give me your username.
