Amu meets a super-peppy transfer student at Seiyo Academy Elementary School named Hiiragi Rikka at school one day. Not only can she see Guardian Characters, but it seems she has some other, mysterious powers as well. When she sees the work that Amu and the other Guardians do at school, she's awestruck. Each 24-25 minute episode consists of a series of variety show style shorts (including Shugo Chara! Pucchi Puchi) totaling approx. 9-10 minutes, followed by the main 11-12 minute animation titled Shugo Chara!!! Dokki Doki which is the actual continuation of season 2 and comes with it's own opening animation. The remaining time is occupied by live action padding between each section and capped off with the opening/ending themes at the beginning and end of the episode. (Source: AniDB)

At Kaimei High School there is a special club dedicated to helping others known as the SKET Brigade. The brains of the group is Kazuyoshi "Switch" Usui, a tech-savvy otaku who speaks through speech synthesis software, while the brawn is provided by Hime "Himeko" Onizuka, the hockey stick-wielding girl once known as "Onihime." And last but not least, their leader is Yuusuke "Bossun" Fujisaki, whose latent ability is evoked by his goggles, allowing him to summon the awesome power of extraordinary concentration. However, most of the school only know them as the club that handles odd jobs. Many of their days are spent in the clubroom slacking off, but when there is something to be done, they give their all to help others—usually in sincere, but unintentionally hilarious, ways. The SKET Brigade do all they can to provide support, kindness, encouragement, and troubleshooting to any students crazy enough to ask for their services. [Written by MAL Rewrite]
