It is a copy of Sailor Moon, which came out 15 years before Shugo Chara (SM- 1992, SC- 17).
Basically about some girl who transforms and fights x eggs and monsters (second season) episode after episode after episode.
The people who created this piece of junk obviously have no creativity.
Anime Executive #1: Damn, we're losing a lot of revenue due to the economic downturn.
Anime executive 2: Oh hell just copy Sailor Moon and release it under the name Shugo Chara it will sure get all the wapanese fanboys excited.
