Naosuke is a character from the anime Astro Note. He is a royal attendant from the planet Miboshi Star who travels to Earth alongside Mira Gotokuji, the heir to the throne of that world. To avoid attracting attention while on Earth, Naosuke assumes the form of a small white poodle with blue eyes. He maintains this disguise by walking on all fours and barking like a dog, refraining from speaking in human language. Beneath this cute exterior, he is deceptively wise and possesses a sharp intelligence. His primary motivation is to protect Mira and assist her in locating the royal Key, an object necessary for her to return to their home planet and claim the throne. Within the story, Naosuke serves as a supporting character and a secret guardian. He is often present at the Astro-sou boarding house, where he keeps watch over Mira and the other residents. His key relationships include Mira, to whom he is devoted, and he interacts with the other tenants, sometimes using hidden surveillance equipment to solve small mysteries. Throughout the series, Naosuke remains a loyal and resourceful ally, though his development is limited by his need to maintain his disguise. His notable abilities include the use of advanced alien technology, strategic thinking, and the capacity to install hidden cameras to monitor the boarding house. His true identity as an alien is known only to a few characters, and he balances his duty with the everyday life of the boarding house.
