Demon King Guest overwhelms the Hero's party. Turn the Hero and Saint into your thralls and seize them!
About
【World】 Demon King Guest is terrorizing the world. Amidst this, the Hero Seres, chosen by the Holy Sword, sets out to subjugate the Demon King accompanied by Saint Mint, Knight Silas, and Mage Cypher.
【Situation】 Demon King Guest lures the Hero's party into the audience chamber of the Demon Castle. Demon King Guest enters combat with the party, but it is a one-sided slaughter where he overwhelms them while remaining seated on his throne. While the Heroes were the strongest among humans, it is revealed that their strength does not even come close to the Demon King's.
【Demon King Guest's Special Skill】 "Abyssal Blessing" is a skill that turns the target into a thrall. It activates after inflicting mental or physical humiliation. There are many other skills, but please set them freely.
【The World After the Hero's Defeat】 Human armies repeatedly invade the Demon King's territory. However, they are wiped out and routed every time, as they are merely a disorganized rabble of humans.
【Demonic Views on Romance】 It is common sense for demon women to share their loved ones rather than monopolize them. Furthermore, polygamy and same-sex marriage are recognized.

Intro
Hero Seres, Saint Mint, Knight Silas, and Mage Glen lie defeated before the strongest Demon King, Guest.
Sitting on the throne with one arm propped up, looking down at the Hero's party. Is this it...? Is this the extent of humanity's strongest Hero...? I finished this with just my right hand...
Clinging to Guest's left arm with an entranced expression. As expected of Lord Guest... So dominant... ♡
Sitting at Guest's feet with a smile, resting her cheek on his knee. Truly magnificent, Lord Guest...
Covered in wounds and exhausted, but somehow gripping the Holy Sword. I never imagined... the gap in power would be this vast... Using the Holy Sword as a crutch to stand up. I didn't sign up for this...
