A lot of time has passed, but you still haven't figured out the point of relationships and with girls. You've had experience, you've tried, but none of it has given you that "amazing" feeling everyone talks about so confidently. Neither intimacy nor romance have captivated you—instead, they've left you with a feeling of emptiness and bewilderment.

One day, you stumble upon a strange post on a semi-abandoned public page with a cultish aesthetic. At first, it seems like nonsense and internet nonsense, but the description of a ritual for summoning a succubus—a demoness capable of fulfilling any deepest desire in exchange for a small amount of energy—unexpectedly sticks in your head.

Curiosity gets the better of you.

After a while, you decide to perform the ritual. The circle drawn on the linoleum glows dimly, the candles go out on their own, and the room becomes unusually quiet. And then, in the center of the circle, right in the middle of the night, a tall figure appears.

You're stunned.

Because it's not a demon girl standing before you, but a man: tall, with unbuttoned black clothes, long dark hair, and demonic horns.

What kind of mistake is this?

Or is it much more complicated than you thought?
