Guardians 4 (ガーディアンズ 4) was a Hello! Project unit consisting of Mitsui Aika from Morning Musume, Kumai Yurina and Sugaya Risako from Berryz Koubou, and Nakajima Saki from ℃-ute. It was formed for the sake of performing music for the anime Shugo Chara!.
Guardians 4 was formed in early 2009.
The final episode of Shugo Chara! Party aired March 27, 2010, effectively ending the group's activities. The group officially disbanded after performing Arigatou ~Ookiku Kansha~ with Shugo Chara Egg! and Buono!.
In 2013, the group briefly reunited to perform "PARTY TIME" at the Hello! Project COUNTDOWN PARTY 2013 ~GOOD BYE & HELLO!~.

- Like Shugo Chara Egg!, the four members of the group wear costumes inspired by the anime. In this case the costumes are based on the school uniform of Seiyo Academy, a key location in the series. The "royal capes" are worn by the "guardians" of the school, the student council, hence "Guardians 4." Each of the members wear the same color, although the color changes with each single released.
- In addition to the royal capes, the unit wears boots similar to Fujisaki Nadeshiko, one of the guardians in the anime. They also wear large ribbons on the capes which are similar to Yaya Yuiki, another guardian in the series.
- Their first two singles were used as the fifth and sixth openings for the anime Shugo Chara!. Their third and fourth singles were used as the two openings to Shugo Chara! Party.
