There are very few artists that do no use sex appeal of some sort. However Ayu always seem to have a good reason for using it in a PV to get the point across. Even when she was modeling for Wacoal her ads seemed more classy then other underwear ads I've seen in the past. Honestly on the top of my head the only singer I can really think of that I've never really seen use sex appeal is ayaka, unless I've missed something.
