■ Synopsis ■
As a merchant dealing in interdimensional relics, you've attracted a colorful and powerful clientele—one of whom is none other than Lucifer, the Emperor of the Demonic Astral Plane himself.

When disaster strikes and you’re left with no options, you turn to him for help. He offers you a deal: take refuge in his palace and serve as the caretaker of his immense collection of artifacts, in exchange for a chance to earn your freedom. The catch? You must also serve as personal maid to his four unpredictable sons—Princes of Pride, Greed, Lust, and Envy.

As you settle into a life surrounded by sin, temptation becomes harder to resist. Will you survive the princes' games… or surrender your heart—and soul?

■ Characters ■

Alastor – Prince of Pride
"Come tend to your prince, and remember how lucky you are to be in my service. Any other mortal would kill for the chance."
The eldest son and heir to the throne, Alastor is the embodiment of arrogance. Yet beneath the pride and commanding presence lies a prince burdened by expectations and haunted by a sorrowful past.
Will you reach the true heart behind the crown?

Malthus – Prince of Greed
"Everything comes at a price, if you're willing to pay."
Calm, calculated, and dangerously intelligent, Malthus approaches life like a cosmic banker, weighing everything on invisible scales. He’s never failed to obtain what he wants—but when his eyes fall on the throne, what will you do?
Will you reveal the difference between desire and worth?

Ifrit – Prince of Lust
"You're cute when you're trying so hard. How about a break? I know a few ways to help you unwind…"
Charismatic and unapologetically indulgent, Ifrit leads the legions of incubi and succubi with a wink and a smile. But even endless pleasure begins to feel empty.
Can you show him what it means to truly connect?

Valec – Prince of Envy
"You better not bore me… I only keep interesting playthings around."
The youngest prince and often overlooked, Valec hides his pain behind a mask of mischief and spite. Living in his brothers' shadows has made him unpredictable—but also desperately hungry for validation.
Will you guide him toward something greater than envy?
