Shugo Chara Egg! will release a new single on February 25th called Shugo! Shugo!. This has been confirmed by member Fukuda Kanon on her blog. The song will be used as the new opening theme for the anime Shugo Chara Doki!!.
Great news. Loved their last single (will write a review on it soon) and I hope this one will be just as good.
