My interest in the song skyrocketed thanks to help from DMX and Sean Paul:
Fukui is right outside what's considered the borders of the Kansai region, so that's probably what leads to confusion for some people. I'm a bit of a geography nerd so stuff like that tends to catch my attention.
As for the song, I love the dancehall-inspired beat used during the verses (which served as inspiration for the mashup I made), and Tsunku's little "dadada" parts add a nice touch to it. Ai-chan did a great job taking the lead vocals, establishing her status as a more than capable replacement of Nacchi in that role. The lyrics have contributed to my desire to learn a Kansai dialect (especially with Yossy's monologue intro), though I probably should focus on getting a better grip on standard Japanese first.
The PV was somewhat interesting with the red overtones, low lighting, and names spinning around each member, though beyond that nothing much remarkable about it. The fairy theme of the costumes and single cover didn't really fit the theme or sound of the song, although it would've been a lot more interesting if they ever tried to really force the combination.
Looking at the history of things, this song can be considered the end of H!P's second major transitional phase that started a year prior with Nacchi's graduation, Minimoni disbanding, and Berryz Kobo debuting. With Rika departing for v-u-den, Mari laying low due to scandal, and the pending arrival of a 7th generation member, both Morning Musume and Hello Project looked like very different landscapes compared to the way things were not too long beforehand.
Also, Tsunku did his own version...but it sounds like some random guy doing karaoke:
