Atsuko Natsume  Atsuko Natsume, known as Nuku Nuku (English: "snuggly-wuggly"), is the main protagonist of the "All Purpose Cultural Cat Girl Nuku Nuku" OVA, TV series, and DASH OVA. In the DASH series, Atsuko is named Atsuko Higuchi, rather than Atsuko Natsume, but retains the Nuku Nuku nickname. In all three, her Japanese voice actress is Megumi Hayashibara and her English voice actress is Allison Keith. In the OVA and TV series, Nuku Nuku is shown as a green-eyed, magenta-haired young girl of around fourteen to sixteen with a large bust, while in DASH, she is depicted as a nineteen-year-old girl, with green hair and golden eyes. In all three incarnations, Nuku Nuku will often have robotic cat ears pop out of her head. Atsuko Natsume is an alias that Nuku Nuku was given to pass as a real girl; she prefers to be called Nuku Nuku which is considered her true name. In truth, she is a biotech-type android of sorts with the brain (or nervous system as some sources claim) of a cat inserted inside. She was originally a cat until an incident (differs depending on each series) caused her brain to be transferred into the body of a war robot built by Mishima Industries. In the OVA and TV series, Nuku Nuku was created by Kyusaku Natsume, while in DASH, she was created by a friend of his. Regardless of which series, Nuku Nuku lives with Akiko, Kyusaku and their son, Ryuunosuke, who she considers her family. In the OVA, Nuku Nuku acts as the protector for Ryunosuke while he's in the middle of a custody battle between Kyusaku and his wife, Akiko, the granddaughter of the weapons-producing Mishima Industries. They parted when they argued about the usage of his NK-1124 android (who would become Nuku Nuku), and Kyusaku took their son with him. In the TV series, Nuku Nuku's role as protector changes, since Akiko and Kyusaku live together (albeit dysfunctionally and always arguing). Instead, she's protecting her family and her classmates from the machinations of Mishima Industries (whose president is different in this series).
