Kilala & Ulala (キララとウララ (Kirara to Urara)) was a Japanese idol duo characterized by their fast-paced techno kayo sound and flashy costumes. It was comprised of Kanako Ohtani (大谷香奈子) and Nagisa Amano (天野なぎさ). Their performances of their first single "Senti Metal Boy" (センチ・メタル・ボーイ) (1984) became some of the first in Japanese pop to utilize headsets. The duo broke up in 1986 after only three years of activity.
