If you haven't noticed by now, I got a twin sister who goes by the name of Mariya Fleischer, a mercenary who works for some criminal organisation. No, I am not evil actually. I have no idea why people seem to like Mariya more than me. In fact, I think I am a better girl than her. If you compare my genius brain, my killer looks and great skills in bed against my wimpy sister, you know definitely agree. I know you will, don't you? Mariya claimed that Fleischer isn't even her real family name and she chose it randomly from a long list of names long ago, but that's not true. I will tell you right now that that's our family name, even though she cannot remember it. Do you want to know why? Well the price for knowing is to be my slave for a month, a fair deal isn't it?
