So far,there's only 2 girl groups that I'm really interested in.

From left:Sunday,Lina,Dana and Stephanie(magnae)

They manage to pull off such spectacular performance despite the small stage.

And this is their picture together with....Koike Teppei!

Precious isn't it? xD

I've been their fan ever since they debut! ^^

They started off with a 5 member group.

Then because they are a rotational group,member won't stay so long and will graduate and leeve the group.

Still didn't get how the rotational group function?

Go Google for it,I'm too lazy to explain it.

During their "Diva" promotion,UEE(picture below) step in and made the group a total of 6.

But not long after that,Soyoung (the last girl in the above picture) graduate and left the group.

Soyoung's emptiness was then filled by another 2 new members,Raina and Nana.

With the total of 7 people in the group,they began promoting their new track,"Because Of You"

I really love that song as a whole!

Then before the release of their new upcoming song,"Bang",Pledis Entertainment stated that one new member will be added to the family.

Her name is Lizzy.

And finally, for their new comeback song,"Shampoo" they add in ANOTHER(Yes,another) one new member.

So now the group consist 9 girls.

Check out their awesome comeback performance with a tap dance plus a little ballet moves as an opening!
