Is there any story reason why Peridot has Mandark Tech?
Yup,
First i was thinking that she would be working with dexter at Dexlabs. Then i was thinking about how Peridot and Pearl kinda have a rivalry, which led me to the idea of one of them would be at Dexlabs and the other would work with Mandark. So i made Peridot work with Mandark instead of with Dexter, since it feels more right for Pearl to work with Dexter.

I tried coloring and shade a sketch i did of Anais
