Mich is the pet of a young man that steals a lot. He has been taught to fetch items from stores and give to his owner, and while he does that he wears his little bandana mask in a silly attempt to cover his face that actually works from time to time.
Mich is very loyal to his owner and enjoys what he does to make him happy; he's quite mischievous and playful and believes what he's doing isn't wrong, which doesnt matter to him as much as it matters to make his beloved owner happy.
