For gravure/idol fans only!
While the star in the video (Rei Amami) is certainly charming, bringing with her the typical naughty/playful persona that most idols have, it's certainly nothing new to those who know what to expect. The UMD contains a mini-game of sorts wherein you play rock/paper/scissors against Rei. There is also a short video of her where you choose what type of clothing/accessory you want her to wear.
To those who collect these type of movie/video this is, it's a worthy addition to your collection. For everyone else, though, I'd give it a second thought.
