OVA
Description
Kyusaku Natsume is a genius inventor specializing in robotics and high-tech devices. Formerly employed by Mishima Heavy Industries, a company owned by his estranged wife Akiko Natsume, he designed robots, weapons, computers, and other advanced technologies during his tenure. He resigned upon discovering his latest creation, the MK android, was intended for destructive applications. Kyusaku subsequently left both the company and his wife, taking their young son Ryunosuke Natsume and the MK android prototype.
During a Christmas Eve car crash while fleeing Akiko's henchwomen Arisa and Kyouko, Ryunosuke's cat sustained fatal injuries. To save it, Kyusaku transplanted the cat's brain into the stolen MK android body, shaping its appearance into a teenage girl. This created the android Atsuko "Nuku Nuku" Natsume. Kyusaku considers himself a responsible father despite his eccentricities and trusts Nuku Nuku to protect Ryunosuke.
Kyusaku exhibits a laid-back and careless demeanor, though he is not without seriousness. He experiences chronic insomnia and becomes intensely focused when developing new inventions, often creating specialized gadgets to enhance Nuku Nuku's capabilities during her battles against Mishima Heavy Industries' forces. He takes pride in Nuku Nuku's loyalty and his own engineering work. While Akiko's personality contributed to their separation, Kyusaku retains underlying affection for her, albeit with no desire to cohabitate.
In the alternate continuity of *Nuku Nuku DASH!*, Kyusaku is not Nuku Nuku's creator but a friend of her actual creator, Professor Higuchi. The Natsume family encounters the memory-deficient android Atsuko Higuchi (Nuku Nuku) after she escaped Mishima Corporation. Kyusaku shelters her and later discovers her android nature, secretly investigating her origins in his hidden home laboratory. He withholds this truth from his 14-year-old son Ryunosuke, who develops romantic feelings for Nuku Nuku. Kyusaku's role shifts to supporting Nuku Nuku as she confronts Mishima's schemes and her own past, including a twin android designed for destruction.
Across all media iterations, Kyusaku consistently provides technological support during conflicts with Mishima Heavy Industries. His relationship with Akiko involves ongoing tension over Ryunosuke's custody and Nuku Nuku's ownership, often escalating into comedic or large-scale confrontations. Despite varying narrative contexts, his core traits—inventive brilliance, paternal dedication, and a casually eccentric personality—remain central.
