Shugo Chara Egg! (?????????!, Shugo Kyara Eggu!?) is a Hello! Project unit originally consisted of four Hello! Pro Egg members: Ayaka Wada, Yuuka Maeda, Kanon Fukuda and Akari Saho. The group was announced on September 20, 2008 and debuted with a live performance. Shugo Chara Egg's purpose is to sing the opening theme songs for the anime Shugo Chara! Doki—, the anime that Hello! Project group Buono! had previously performed opening and ending songs for. Even though Shugo Chara Egg! performed the anime's opening songs, the ending songs were still sung by Buono!. Additionally, each of the four members wear costumes based on the "character transformations" (a key element of the series' plot) of Amu Hinamori, the main character of the series. Shugo Chara Egg's debut single was titled "Minna no Tamago" and was used as the first opening theme for Shugo Chara!! Doki-. It was released on the Pony Canyon label on October 12, 2008. The unit S/mileage has the same lineup as the original Shugo Chara Egg!, with the exception of Ayaka Wada being leader, and in which Saki Ogawa is a member instead of Akari Saho. A new second generation Shugo Chara Egg! was created in August 2009 adding Mizuki Fukumura and Irori Maeda to replace Yuuka Maeda and Kanon Fukuda respectively. An audition is being held to decide the replacement for Ayaka Wada.[1]
