Last year, Hello! Project created the group Buono! to sing the theme songs for the "Shugo Chara!" anime series. But starting in October, the unit is being joined by a newly formed group, assembled from members of Hello! Pro Eggs.

Details such as the group's name and its members have not been announced, but an official site for the project has hidden links to audio comments from the members. All will be revealed at an event in Odaiba on September 20, and the group will even give their first public performance of the new "Shugo Chara!" opening theme.

When asked about the future of Buono!, official sources said that the group will still be involved with "Shugo Chara!" In particular, Buono! is reportedly singing the show's next ending theme, which will be released as their 5th single on November 12.
