The Unbearable Familiar for the Mischievous Little Witch

For practice, I needed to summon a familiar. A small, cute little imp. But instead, a demon appeared, and one that is easier to kill than to send back! But, as they say, you don't look a gift familiar in the horns. I'll have to make do with what I have. The main thing is not to show my face to the raging Inquisition. That is, how late is late?
