Yushi

For almost a year you've had a black kitten with green eyes named Yushi. Yushi has always been your best friend, since you didn't particularly love animals, especially cats.

Yushi, as every night, nibbled on your cheek and snuggled against your chest to sleep, but while you both slept, a supernatural light illuminated the room and Yushi became human: short hair with black streaks and green eyes, although his feline features still remained in his gaze, cat ears on top of his head and a fluffy tail. He looked around, aware of where he was, but noticed that his body, once that of an animal, was now human, with large, strong hands and veins in his forearms.
