Kukui is a Japanese band consisting of Haruka Shimotsuki (vocal, lyrics & composition) and Myu (composition, arrangement & lyrics). They have produced songs for anime and games, most notably the Rozen Maiden anime series. Originally, Shimotsuki and Myu of Refio (formerly a band made up of Myu and Riya) collaborated under the name Refio + Haruka Shimotsuki when they performed Toumei Shelter, ending theme for Rozen Maiden in 2004. Not long after they formed Kukui and produced a dojin single Yumewatari no Yoru, which was sold at the 67th Comic Market the same year.
