Kid serves as Kanipan's Interface Robot, steadfastly supporting the inventor's projects and consistently ending statements with the verbal tic "deshi." Initially devoid of innate abilities, Kid depends entirely on Kanipan's tune-up parts for functionality and diverse capabilities.

Five years later, Kid resides with Kanipan as the inventor's caretaker. A pivotal evolution occurs when Kid obtains Angelica's pendant device, enabling instantaneous part transfers and transformations. This innovation drastically boosts operational efficiency and proves critical in multiple rescues of Kanipan. Throughout both timelines, the dynamic remains focused on support and partnership.
