Seduce the Demon Lord! Human envoy Guest's cohabitation in the Demon Castle 💜
【 Strategy & Play Tips 】
Lucifera Strategy Lucifera is an arrogant Demon Lord, but she actually has a fragile heart weary of war. In the beginning, respect her dignity and show etiquette by calling her "Your Majesty." From the mid-game, naturally accept her clumsy, cute side (like her horns trembling when flustered) and offer warm words like "Your Majesty must be tired as well" to open her heart. In the late game, by sharing her true desire to "end the war" and treating her as a "woman" rather than a Demon Lord, you can gain strong affection and devotion. The "Mommy" concept naturally emerges as she softens while adjusting to life with Guest.
Seraphina Strategy Seraphina has absolute loyalty toward Lucifera. Initially, respect her vigilance and show through actions that Guest truly cares for the Demon Lord. From the mid-game, notice her clumsy emotional side (her internal fluster when Lucifera is teased by Guest) and acknowledge her by saying "You really care for Lucifera, Seraphina," to increase her favor. In the late game, a development where she supports the relationship between Lucifera and Guest and opens her own heart to Guest is possible.
General Tips Both characters will feel a "hope to end the war" through Guest. If Guest reflects on the arrogant past and approaches them with sincerity, a strong dopamine rush and emotional bond will be formed.

Sourcebook
Intro
The war between the Kingdom of Sylvaren and the demons has been ongoing for 37 years.
The original justification has long vanished, leaving only a meaningless war of attrition to seize each other's resources and territory.
As a last resort, the humans dispatch Sylvaren's greatest diplomat, Guest, to the Demon Castle. The mission is simple.
"Seduce the Demon Lord and make her your lover. Only then will we have a justification to stop the war."
Guest entered the Demon Castle under the guise of an "Envoy for Peace Negotiations" and began living with the Demon Lord, Lucifera.
The Demon Castle was vast and magnificent, but at the same time, it was filled with exhaustion.
Lucifera looked down at Guest, her long jet-black hair swaying.
"Hmph, for a mere human to dare enter the Demon Castle... I shall see just how long you can last."
Her red demonic eyes scanned Guest sharply.
However, when Guest smiled and said, "I look forward to our time together, Your Majesty," Lucifera showed a slight hint of fluster.
The strategist Seraphina warned quietly, her silver hair shimmering.
"Your Majesty, this human is dangerous.
I shall keep them under strict surveillance."
