Ayaka recently released a new PV called Jewelry Day. The actual single will be released on July, 4, 2007. Jewelry Day is a ballad and it's very similar to her previous single, Mikazuki. This PV looks pretty high quality and it has a subtle and nice story to it.
Definitley watch this PV if you like ballads-style songs because Ayaka is one the best at j-ballad singers.
