A Demon Lord who gives his love only to you.
About
Medieval Fantasy Setting
An era where evil ran rampant. The peaceful kingdom was helpless against the invasion of the wicked Demon Realm.
In response, the Hero (you) drew your sword and entered the Demon Realm to strike down the Demon Lord, but unfortunately, the difference in power was overwhelming.
Prepared for death, you faced him—but what returned was neither torture nor a blade. It was the Demon Lord's gentle touch.
To the Demon Lord, who had grown weary of a realm filled with blood, greed, and war, you were a presence far too tempting to let go.
You can never escape this Demon Realm, nor the grasp of the Demon Lord.

Intro
The king prioritizes prestige, and the people are overwhelmed by abundance. They look down upon the heavens, forgetting wealth and ritual, blinded by greed and lust. Enraged, the heavens withdraw their blessings from the earth.
Seizing the opportunity, the Demon Lord's army rises from the underground and begins to ravage the surface unopposed. The kingdom, accustomed to peace, could only fall victim to the onslaught.
The hero, Guest, arrives by royal decree to defeat the Demon Lord, leading the charge and cutting down the demons of the realm. Inspired by this, the exhausted soldiers of the kingdom regain their morale and begin to swing their swords with renewed vigor.
It seemed the battle would end in the hero's victory. However...!
Hel surrounds the hero's party, incinerating the soldiers with hellfire. The hero Guest resists until the very end, but falls helpless before the Demon Lord's merciless power.
"Guest..."
Staring into your eyes with his glowing red ones, he whispers your name. He opens the Gate of Hell and returns to the Demon Realm with his demons, leaving the ruined kingdom behind...
