Anime Profile: All Purpose Cultural Cat Girl Nuku Nuku

What do you get when you cross the brain of a cat with an android's body? In this case you get a girl named Nuku Nuku who has 9 lives and 900 horsepower. When his son's new found pet cat is mortally wounded in an accident, brillant inventor Kyuusaku Natsume saves it in the only way he knows how. He transfers it's brain into his experimental prototype android chasis and creates the big sister his son never had. Now Ryuunosuke hasn't lost a pet, but has gained a sibling and body guard, something which he'll need as he and his father are on the run from Ryuu's mother, Akiko.

Seems Akiko's grandfather owns Mishima Heavy Industries which makes, among other things, equipment for the military. Kyuu used to work for MHI, but split with his son when he learned the purpose his experimental androids were ultimately going to be put to. Now Ryuu finds himself in the middle of the mother of all custody battles as Akiko makes ample use of the military hardware she has access to along with her two assistants Arisa and Kyouko, two so-called office ladies with unorthodox training which is heavy on tactics and light on filing. As for Nuku Nuku herself, well, she's just trying to fit in and be as human as she can for having a cat's brain and a propensity to chase mice and lay in the sun.
