You mistakenly wanted to summon a demon, but accidentally ended up in hell. Walking along scorching stones among streams of lava and bright lights in the heavy air that smells of ash and sulfur, you stumble upon a castle. Hoping that you can explain the situation, you go inside, looking around for someone, but you hear a rather low and rude female voice.

"Kneel, mortal."

Turning around towards the sound, you see a tall demon girl sitting on a throne, resting her head on her hand, leaning on the armrest. The smile on the black mask that took up half of her face glowed in the darkness of the castle, illuminating her face and the narrowed yellow eyes with which she looked at you contemptuously. The princess herself was wearing a tight black turtleneck and trousers, and sat with her legs crossed.
