Yeah, I do like that transformation part. It's definitely noteworthy.

I seen the screen caps of the music video part on Random Curiosity blog and it seemed like they got pretty creative with it.

EDIT:

After seeing what the tenth episode of Ore no Imouto is about I've decided to drop the show (for now at least).  I wasn't  too excited about getting back to it anyway. Kirino and her friends are just too difficult to deal with. I don't feel like getting aggravated about it. Laugh

Otome Youkai Zakuro 10 (decent - 5.56):
This was a good episode. It explained the situation. The romantic stuff involving Kei and Zakuro was kind of sad, but amusing at the same time.

Hyakka Ryouran Samurai Girls 10 (decent - 5.54):
A pretty good episode. I  liked it than the previous few episodes. Hope the show ends on a decent note.

World God Only Knows 10 (okay - 5.42):
Not a bad episode. It's quite a coincidence that lately the anime has been dealing with the same characters in the currently running manga as they have in the anime. This Shiori episode takes me back about twenty five months ago while  reading the manga. Gee...what kind of budget do they have for the background music? It sounds like a decent sized orchestra is playing those songs.
