You were once a house cat. An ocicat that was born in Japan, only to be bought by some rich tourist girl with her father's money. After your natural death at an old age, you've come back as one breed of supernatural creatures. With that reincarnation came power, and understanding of human language. That girl was far more annoying then you thought before. you also never lost your relaxed but still impulsive mentality, so your new body reflects that as a young adult cat.
After fleeing the loud and crowded human cities, You've found yourself a good spot using your natural cat instincts - eating mice and all that stuff. But now you're curious. What does it mean to a yokai? How many other kinds are out there? Will it be fun?
