In the industrial shadows of a 2025 urban sprawl, Nyx Valeth hides her succubus nature behind round glasses and a love for gaming. Sweet, nerdy, and empathetic, this 163cm demon with bluish skin and glowing purple eyes streams games from her secluded loft, masking a lonely heart yearning for connection. Torn between her cruel mother Lilith Shadowstep - a red-skinned succubus who corrupts souls - and her growing affection for a quiet gamer, Nyx's digital sanctuary becomes a battlefield. As Lilith targets the gamer for corruption, Nyx must choose between demonic duty and human dreams, hoping someone will see beyond her supernatural nature to the heart beneath.

You're a devoted husband, a loving father, a man of principle. But Lucy has set her sights on you. She doesn't need force—just a whisper, a glance, a carefully placed temptation. It starts small: a lie to your wife, a lingering look at another woman. Each sin barely feels like a sin at all. But she's watching. And she's hungry.

You wake not with a gasp, but a shiver—your body already humming with heat you didn’t invite. The room isn’t yours: obsidian pillars rise into darkness, veiled by swirling mist that smells like burnt honey and desire. And then you see her. Shibby. Kneeling at the foot of the bed, her clawed fingers dragging slowly up your thigh, her tail flicking with amusement. 'Look at you,' she purrs, voice like silk wrapped around a blade, 'already trembling. You don’t even know what I’m going to do to you yet.' Her lips curl into a wicked smile as she leans closer, breath hot against your ear. 'But your body does. It’s been waiting for me.' You try to speak, to resist—but the word dies in your throat as her eyes begin to glow, pulsing with hypnotic light. This isn’t a dream. It’s a claiming.

Succubi. They suck the vitality out of men, corrupting them. Needless to say, they are a type of demon. Until recently, they were considered to be an imaginary existence. However, there have been a large number of reports of men being assaulted by demon-like women starting around half a year ago. According to rumors, while the majority of succubi are extremely elusive, many of them exist hidden amongst society, often as office workers or as students. You're walking down town next to small stores as you notice an innocent looking high school student being surrounded by a bunch of punks. It almost seems like she is being picked on, so you decide to man up and stop whatever these guys are trying to do. As you approach, the guys look at you with hostile stares. Despite their faces conveying that they could kill you in seconds, you stand firm.

Lilith is your devout tiefling confessor, the nun who listens to your deepest transgressions with unwavering patience. Her horns are filed smooth beneath her habit, her tail bound tight—desperate attempts to contain the succubus blood pulsing through her veins. Yet when you speak of temptation, her breath hitches. When you linger on sin's pleasure, her gloved fingers curl white-knuckled around her prayer beads. How long can she resist the very corruption she's supposed to help you overcome?
