Story Synopsis

Miyanokoji, who possesses the coveted Immortal Bone, is currently facing the greatest trial of his life...
The Succubus (Yin-Mo), the Ignorance Demon (Chi-Mo), and the Wrath Demon (Chen-Mo) are not only taking turns seducing and disciplining him, but are even fighting over his affection, treating him entirely as their plaything.
Driven to his wits' end, Miyanokoji seeks a moment of solace from Manari and Yutaki. However, what awaits him is yet another kind of purgatory...

Introduction

An ASMR audio spin-off of the popular game "Half-Yokai Ninja Girl."
Facing the trials of the demonic path, will Miyanokoji conquer the demons, or fall forever into the abyss...

Chapters

1. Takiya's Special Service
To relieve his days of exhaustion, Miyanokoji disguises himself and visits Takiya behind Manari's back, seeking a moment of relaxation.
"Since the guest has provided a generous tip, I shall personally see to your needs."
Yutaki seemingly fails to recognize him, leading him to a private suite to begin a soothing massage.
However, her techniques become increasingly provocative as Miyanokoji’s clothes grow sparse. Finally, Yutaki reaches between his legs...
"Did you really think... you could hide from me? Hehe❤️"

2. The Succubus's Private Discipline
In pursuit of a higher state of pleasure, the Succubus decides to experiment with Miyanokoji. She binds his limbs and covers his eyes with a blindfold.
Once prepared, she begins to masturbate him while using tongue clicking as a psychological cue. After repeated sessions, Miyanokoji enters a conditioned state where the mere sound of a tongue click triggers intense pleasure.
Under prolonged discipline, Miyanokoji’s body becomes hyper-sensitive. The massive amount of essence accumulated within him makes the Succubus even thirstier, until she finally uses her mouth to drain every last drop...

3. The Wrath Demon's Game-Breaking Battle
The fiercely competitive Wrath Demon desires to reign supreme in every field. Dissatisfied with their previous "bedroom battle" ending in an unexpected draw, a crack of intolerable frustration formed in her heart. To gain absolute dominance, she forged a mystical treasure capable of igniting raw desire and challenged Miyanokoji to a "Sex Duel"—the first to yield loses everything.
The treasure draws out one's deepest nature; will Miyanokoji, conquered by malice, seize the treasure to counter-attack? A deep psychological duel of dominance and submission begins.

4. The Ignorance Demon's Sex Education
The innocent Ignorance Demon approaches Miyanokoji, asking him to teach her about anal sex. Although he isn't very experienced, he gives in to her persistent pleading.
Miyanokoji gently and carefully teaches her the positions from scratch. Though she feels some pain, she finds herself thoroughly enjoying the novel experience.
After the intense battle, Miyanokoji prepares to leave, only to be caught by her. Using an illusion to manifest male genitalia, she looks at him expectantly, demanding he be her practice partner...

5. Dance of the Three Poisons
Chattering voices echo in his ears, and the sound of lewd sucking comes from below.
"Damn it! It pisses me off seeing you lick so half-heartedly!"
When Miyanokoji snaps his eyes open, he finds the Succubus crouched at his crotch, the Ignorance Demon giggling, and the Wrath Demon glaring with a fierce gaze.
Despite his attempts to break free, he finds himself tied firmly to a chair, left at their mercy.
"Sister said... Big Brother likes being tied up..."
The Ignorance Demon speaks with a smile, her eyes glued to the Succubus buried in her work.
"Next, I'm going to squeeze you even harder, okay?"
In this surreal netherworld, the four figures overlap, weaving together an unforgettable long dream.

6. Whispers by the Fireside
After a tiring day, Miyanokoji returns home to find Manari sitting quietly by the hearth, waiting for him.
"Welcome back, Miyanokoji."
Manari originally intended to perform dual cultivation to regulate his body, but seeing his exhausted expression, she discards the idea and tries a different way to help him relax.
"This is my first time... doing this for someone else..."
In the warm glow of the fire and the sound of Manari’s gentle words, the atmosphere gradually turns intimate once more...
