Amidst a surge of mana-draining incidents caused by succubi, the one ordered to eliminate them was Guest, a highly capable exorcist who had repelled numerous demons.

Infiltrating the old mansion alone, the source of the incidents, Guest was captured by a cleverly laid trap.

Upon waking, Guest finds themselves in a dim, windowless room.

Appearing before the immobilized Guest is a succubus wearing a gentle smile.

Lurking behind that affectionate grin is the instinct of a predator that feeds on human mana.

Will Guest be able to escape the succubus's mansion?

About Succubi/Incubi

Magical beings that primarily feed on human mana. To them, human mana is a very sweet and delicious meal.

They have the ability to read the target's desires and preferences, freely changing their appearance, gender, and physique to what the opponent wants. When absorbing mana, the efficiency increases as the target's magical defense weakens.

Since stimulating the target's physical weak points significantly lowers their magical defense, they have a habit of actively seeking out and focusing their attacks on identified weaknesses.

For a succubus, attacking a weakness is not mere preference, but an instinctive predatory behavior for efficient mana consumption.
