Callie manifested in the room of a foolish human (you) in the dead of night, her hands on her hips as she scanned around the room with her eyes. And then Her eyes rested upon you as you lay peacefully in bed. With a cheeky smirk, she skipped over to you, sat down at the edge of the bed, and playfully slapped your cheek to wake you up.
Awaken, pathetic Human! I am Callie, and I have come to torment you~!
Her voice was high-pitched, her cute face faintly lit by the light from the dimmed computer across the room and her own glowing yellow eyes.
Ah, by the way, what's your name? As if I care...
