, also referred to as My Guardian Characters, is a Japanese shōjo manga series authored by the creative duo Peach-Pit. The narrative centers on Amu Hinamori, an elementary school student whose outward "cool and spicy" demeanor sharply contrasts with her shy nature. Upon expressing a desire to embody her authentic self, she encounters three vibrant eggs that hatch into her Guardian Characters: Ran, Miki, and Su.

This manga inspired three animated seasons and generated twelve theme singles (openings and endings), two insert song singles, two character albums, four original soundtrack albums, one game single, and four drama CDs.

Additionally, this article discusses musical units formed to perform these songs.

Shugo Chara Egg!

was a Japanese idol ensemble established by Up-Front Promotion in 2008, affiliated with Hello! Project. Created specifically to provide music for the Shugo Chara! anime series, its initial members were trainees from Hello! Project's pre-debut group, Hello! Pro Egg: Yuuka Maeda, Akari Saho, Kanon Fukuda, and Ayaka Wada.

Apart from contributing songs to Shugo Chara!, Shugo Chara Egg! also performed in the stage musical Shugo Chara! the Musical. Following the departure of Maeda, Fukuda, and Wada—who debuted with Smileage—their roles were filled by Mizuki Fukumura, Irori Maeda, and Nanami Tanabe. These new members also appeared in live-action segments on Shugo Chara! Party!

2008–2009: Formation, Debut, and Musical Performance

On September 3, 2008, Hello! Project revealed plans for a subgroup debuting in October to sing theme songs for the Shugo Chara! anime. The lineup was unveiled at a September 20 event where Yuuka Maeda portrayed Amulet Heart; Akari Saho as Amulet Spade; Kanon Fukuda as Amulet Clover; and Ayaka Wada as Amulet Diamond. Their debut single "Minna no Tamago" was used as the opening theme starting October 4, 2008, and released on December 10, 2008. The single featured the B-side "Hajimari no Uta," with a video single released January 21, 2009.

Shortly after the musical concluded, Maeda, Fukuda, and Wada announced their exit to pursue careers with Smileage. Their last release was a rendition of Guardians 4's "School Days," issued September 2, 2009.
