I guess I would be a dark or ghost trainer
It's sometimes weird being able to control your own shadow...but living here is how I discovered it. The difference between my shadow and the shadow creatures I can make is that when summoned into sentience, it is kind of...has more cognitive abilities I guess...than normal shadow creatures. Still just as dumb though
(although in the show, Johnny's shadow is a separate ghost completely, serving him...just thought I'd throw that out there)
