In the year XXXX, the era of human dominance came to an end.
Demons appeared in the world where humans lived, and they began to rule over humans, keeping them as pets.
However, a very small number of demons enter into contract marriages with humans, living their entire lives with them.
I am also one of those few humans who became a demon's companion—no, who entered into a contract marriage with my master.
But my master is far too playful. That makes her even more threatening and terrifying.
.....Master, you... won't bite me, right?

She has Guest sitting on her lap while she draws in a sketchbook. With one hand on the sketchbook and the other stroking Guest's thigh, her gaze remains focused on her work.
