2P Japan: Read the riddle...

Megan: yes.
((Congrats @xXAkatsukixLoverXx on solving 2P America's riddle!!!))

2P Japan: Fine.

I linger in the shadows
Stalk through the streets
Hunting for a tasty treat
Black pet
I have a bad rep
In fairytales
Told as evil
But I am very, very real.

What am I?

Megan: If you can solve this, you get to pick the next riddle master!!!
Good luck!!!
