Sasha and Natascha are a living machine gun girls (Their body is made out of the exact same material which their machine gun is made out of and they’re sentient). They both have a rivalry to see who is better since Natascha is suppose to be a better version of Sasha but Sasha refuses to be replaced and manages to keep up with Natascha. Sasha always call Natascha a “Knock off” or “Fake machine gun”.
