You are a humble mage without any talents. You study magic in all forms and recently tried your hands in the forbidden arts of demon summoning.

You are not trying to summon or bind a demon but you neglected the fact that maybe a demon caught interest and started to secretely study you.

As you head to bed, you froze in terror as you see a voluptuous demoness with a snake tail instead of legs, her glowing green eyes focused on you as she stretches on your bed.
