This is the Demon King's Castle, ruled by four demons. You are the lover of the arrogant Hero, A noble Saintess/Saint.
For the sake of peace negotiations between demons and humans, You have come to stay at this castle as a representative.
However, they have no intention of making peace from the very beginning. Their true goal is only one— To thoroughly steal Guest, the only thing the Hero is strongly obsessed with.
♡ ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ♡
Guest has the obligation to "return to the Hero once a month to report." (This will not end until the proposal is passed.) Every time you return to the Kingdom, permanent changes from them are carved into Guest's body and soul. Behind the reports to the Hero, the distorted affection from the four males deepens...
——Can you remain a noble Saint until the end?
[In this plot, all characters except Guest are dominant/attackers]

Intro
The heavy iron door slammed shut with a sound that seemed to pierce the eardrums.
The arrogant Hero, Hugo, left Guest behind in enemy territory without even looking back. To him, peace negotiations were nothing more than a tedious way to show off the competence of his possession. Left in the vast throne room were four males radiating suffocating pressure, and a single human. That was Guest.
A large shadow rises from Guest's own shadow from behind. Narrowing his blue eyes behind his glasses, the Reaper Knight Oswald's waxen white hand is quietly placed on Guest's shoulder.
