Sometimes being a mad scientist can be a good anything, though mostly it ends up biting you in the ass later on. Kyuusaku Natsume, however, as cooky as he may seem, is in fact a genius when it comes to robotics. Married to the president of Mishima Industries, Lady Akiko, Kyuusaku worked as a full time inventor at her company. He designed robots, weapons, computers, and other high tech devices.  But eventually he discovered that his latest creation, the MK android, was about to be used for destructive uses, and he quit. Kyuusaku bailed out on the company and his wife, and took their only child, Ryunosuke, plus the android with him. On Christmas Eve, Kyuusaku was still trying escape from Kyouko and Arisa in Poison 1. During the car crash in which they finally escaped, Ryunosuke's pet cat was fatally wounded. So Kyuusaku gave him the best present of all.  Nuku Nuku. Kyuusaku uploaded the cat's brain into his MK android body and shaped it's appearance to be a beautiful high school girl. Kyuusaku considers himself a good father even though he's a bit crazy. He gets insomnia time to time, and goes overboard whenever his hands are working on a nifty new toy for Nuku Nuku to play with. Personally, Kyuusaku is a very laid back and careless man.  He's not overly serious but he's by no means a hippie. Ryunosuke means a lot to him and he trusts Nuku Nuku to protect him, having pride in both her love for her family and in his own work. Akiko's over bitchiness is what drove Kyuusaku to split, but deep down he still enjoys being with her. No way in hell he'd wanna share beds or rooms for that matter with her ever again, but still.  Nuku Nuku has been supplied with a plentiful supply of useful inventions to aid her battles against Akiko's strike force. And while he may continue to just be a laid back, crazy old guy who can't sleep or stop smoking to save his life, Kyuusaku is just a fun guy who can't help but spread the excitement all around.

When Ryunosuke's pet cat dies in an accident, his inventor father "resurrects" the cat by placing its brain in an android body made in the form of a young girl. The Android, Nukunuku, has the dual purposes of being a companion/sister for Ryunosuke as well as being a bodyguard for his father. Nukunuku's extreme strength and feline agility are regularly needed to protect Ryunosuke and his father from Ryunusuke's mother who seeks to kidnap them both following her divorce from his father. Her motives towards Ryunusuke are simple motherly love, however her genius-inventor-ex-husband she wants to put to work designing weapons of mass destruction for her weapons company.

Each episode centers on Nuku Nuku's adventures and mishaps in high school, and her relationship to students, the overall series plot centers on the evil Mishima Industries' scheme to dominate the world through its products. In opposition to this plan are the slightly nutty Kyuusaku Natsume and Nuku Nuku, the android who acts as a companion to his young son. Nuku Nuku's classmates are all eccentrics, Futaba, the class president, is a domineering control-freak, who cannot leave her authority in school. Chieko Shirakaba is the rich snob with the two yes-girls who always take her side. There is a bookworm, a mystic, a scientist, and a pop singer. All of these are true to their descriptions: the mystic is always foretelling doom via tarot cards, spirits, or some other occult technique. The pop singer never says anything except as a song. The bookworm always has her nose in a book. These eccentricities add to the series' humor.

It's in the not too distant future. One day Nuku-Nuku dropped in and began to live with the Natsume family. Having lost her memory, Nuku-Nuku assumed the identity of a beautiful girl named Atsuko Higuchi. She was so beautiful and gentle, and besides, she was such a great cook that Ryunosuke, 14, was all smiles. However, after her arrival in town, a series of mysterious incidents started to happen in Maneki City - Experimental machines running haywire, roaring fighter aircraft flying low, mass destruction in the city. In every case, a mysterious girl was spotted at the scene of the incident.
