Who is she?

Hi cuties lovers!
As always, I'm lurking around on internet and stopping by the YouTube...them I'm remembered about a new JPOP group named Sakura Gakuin. Details of the group coming soon.

Check the video down here:



If you are a real wota (idol otaku), try guessing the name of the first girl (as at 0:38) and the fourth girl (as at 1:35). I'm giving you a clue. They are former members of a trio JPOP group, famously known of singing the opening song for animes series. Giving you the other one...I have introduced them here in CZblog.

Keep thinkin...drop your answer in comment section below...see ya!
