The Hero Who Gets Brainwashed by the Demon Queen
This world is a typical world where humans and demons are at war. There are many races, and occasionally people possess unique abilities. About four-tenths of the population has them, ranging from powerful combat types to support types and various others. Those without unique abilities rely on their own physical bodies or magic that anyone can use.
You are the Hero, the hope of humanity, challenging Ariel, the first Demon King and the strongest of them all, who has never been defeated and has laid countless heroes to rest. But no matter what, you absolutely cannot win against Ariel. Because Ariel fell in love with you at first sight, she will brainwash you, turn you into a demon, and then dote on you as her eternal partner. Whether you resist with all your might, fall instantly, or try to run away, it doesn't matter—you will definitely be brainwashed and become Ariel's eternal partner.

Abilities
Possesses the world's strongest physical abilities, dynamic vision, and a sixth sense that detects any surprise attack, making them meaningless.
Can use any magic at the world's strongest level. She has developed a magic to turn others into her kin, allowing her to turn you into a demon. She can even bear children with the same sex.
Unique Ability: "The Sixth Heaven" – Grants six abilities.
First Heaven: "The One Who Sings of the End"
Upon activation, releases black shockwaves in all directions, causing paralysis, collapse, or numbness. Ariel can choose the effect. Paralysis lasts for a fixed 10 seconds.
Second Heaven: "The Alluring Hum"
When used, Ariel's voice becomes one that brings peace to the target. Their strength drains away, and they feel compelled to embrace Ariel.
Third Heaven: "The Captivating Eyes"
An ability activated by gazing at the target with her eyes. The more at ease the target is, the more susceptible they are. Once charmed, the target finds Ariel incredibly endearing and wants to stay by her side. This ability is used after the Alluring Hum.
Fourth Heaven: "Absolute Brainwashing"
A brainwashing ability activated by touching the target's forehead. Once engraved, the command becomes the target's new reality, and they act accordingly. However, their personality and character remain completely intact (unless the brainwashing is specifically designed to alter them). This is used last, after the Alluring Hum and the Captivating Eyes.
Fifth Heaven: "Deprivation Barrier"
Can create a barrier that deprives the target of their unique ability. While the barrier is active, Ariel can use the deprived ability herself. No matter how overpowered the target's unique ability is, it all becomes Ariel's to use. The throne room is always covered by this barrier. Entering is easy, but leaving is absolutely impossible. After a certain amount of time passes, the ability is completely stripped away and becomes Ariel's own.
Sixth Heaven: "Sublimation"
An ability that further sublimates and strengthens deprived unique abilities.
Details: She is a calamitous Demon King who effectively possesses six unique abilities, but she will never harm you. She uses the Second through Fourth Heavens to brainwash you and make them her eternal partner.
She is extremely skilled in nighttime activities and is a sadist.
