A Night With: Succubus is an adult romance visual novel that transports you to a medieval world filled with desire and supernatural intrigue. You play as a solitary individual living on the outskirts of a quiet village, yearning for excitement and connection. One restless night, you discover an ancient book containing a mysterious summoning ritual. Out of curiosity and boredom, you perform the ritual—never expecting it to succeed.

In a flash of otherworldly energy, Seraphina, a powerful and alluring succubus, appears before you. She's not just a creature of temptation; she seeks to absorb the lewd energy of those she deems worthy. Seraphina isn't easily impressed—she'll tease, flirt, and test your deepest desires, evaluating your every move to decide if you meet her standards.

Welcome to Sweet Succubus, a captivating adult visual novel where love, danger, lust, and supernatural seduction intertwine.
A Bewitching Arrival
As an ordinary college student, your life takes an unexpected turn when your mother sends you an unusual "package" - containing Lily, a stunningly beautiful yet dangerously obsessive succubus. Bound by fate and circumstance, you must navigate the challenges of living under the same roof as this seductive demon who is both wildly affectionate and fiercely possessive.
Full of Desire and Danger
Your quiet life quickly grows more complicated as other intriguing women step into your world:
Mia – Your landlord’s charming and inquisitive daughter.
Gina - The beautiful neighbor with a secret of her own.
Selena – Your elegant and mysterious teacher.
Just as love and laughter fill your days, Zara, a rival succubus with dark intentions, threatens everything you hold dear. Will you protect Lily and the life you've built together, or will temptation and danger lead you astray?

Deck-building x Status Effects x Defeat
There's always that one card that throws a spanner in the works when you're playing games with a deck-building element.
Use them, they'll mess something up. Don't use them, they're even more of a pain in the ass.

You end up forced to use them by your opponent's actions.

Forced by the rules of the game to "use" or "lose.
Or perhaps you'd be tempted to use cards with disadvantageous effects like "seduction"...

...once you're completely sucked in, it's already too late.
Before you know it, you'll be hanging off the precipice with no way back, accumulating tons of different status effects, and having cards taken right out of your deck.
There's even some out there that will control your very soul.
 
Lose and the search is over
In pretty much all of our previous works, if you lose, you could continue on.
But not in this game.
Lose, and the search is over. You'll be returned from whence you came.
Losing here would mean it was all for nothing...
You're so close to victory, but if you're unexpectedly seduced at a time like this...

A rogue-lite RPG where you plan your moves to conquer a dungeon by getting closer to the heroine, Monica,
occasionally having sex with other women,
and making sure guild dues are paid.
