Doll

Say hi to Doll Kuznetsova, best described as "the quiet kid but extremely Russain." She speaks exclusively Russain, but since everyone seems to understand her just fine, I'm ignoring that plot point. Also, infected by the AbsoluteSolver, a program that can quite literally manipulate reality, at the cost of needing to drink oil to keep temps from rising too high, and increased sun sensitivity. She died, but came back for some unknown reason. Originally hell bent on killing SD-V for killing her parents, seeing the other side made her not as set on revenge. Okay, that's all the major plot points, have fun.
