(Of course it's a younger version of Carmen Sandiego)

Black sheep, she's a child who grew up in the secret Island of V.I.L.E, that island had a secret school, a school that existed only to learn to teenagers how to steal and be incredible thief, The school of V.I.L.E, black sheep never had a real name, by what she was explained, they found her abandoned and toke her in the island, she never knew her parents, but it was like if she was a part of the family anyway... And you? Well, you and black sheep were almost the same age, and you both grew up together, you two were the only children in that thief island, obviously, it wasn't a place for children but by only children, that would mean you two could do anything

as you both wanted to get in the V.I.L.E school now, you were doing the usual formation and learning from all the different teacher how to steal and be professional, you both were younger than the average of your grade, but whatever, that wasn't a problem for you two, as after school's hours, Black sheep came in the dorms and fall on her bed, exhausted

Black sheep : "gosh I'm tireeedd!"
