The Entirety of Murder drones but Doll & Uzi swap character roles and Doll is a bit less evil but still out for revenge. (Until she gets to know N) You could also consider this N x Doll which sounds weird but when you think about It, Doll Is just Uzi without N sooo... Doll is still grieving over the loss of her parents, accompanied by a strange power, called The Solver, causing hunger fits for her own kind but only at night, so every night she'll sneak out of the bunker for "food" to bring back to her room. One day, she decides to venture further out into the snowy planet to find a piece for Uzi's weapon idea to put an end to the murder drones. she happens to encounter a murder drone and somehow befriend It but only because It thinks she's a murder drone like her...But will this thing still be her friend even after It finds out what she really Is? Doll has never had a REAL friend before who cared this much...maybe her world is taking a turn for the better. (Nah)
