What happened with Chiharu and Etsu, Ayu´s coreographers???

[ETERNAL KAMIJO]

When I watch the makings from the promotional videos, I always found Chiharu and Etsu, Ayu´s coreographers, laughing or preparing some steps for diferents songs..... but in GUILTY DVD they don´t appear at all, what is more in "TALKIN´2 MYSELF" making the coreographer is ZIN, one of Ayu dancer (the one who teaches in CDL 07-08 how to dance "MY ALL"). Then in "MARIONETTE" the coreographers are Zin and Maroka (the last is the one who makes that spectacular jump before Ayu stars singing "LADIES NIGHT" in CDL 07-08) or even in "(DONT) LEAVE ME ALONE" the coreographer is Kayano (The girl who wears pink dress in that video).... Where are Chiharu and Etsu????..... I hope they are preparing all the coreographies for Asia Tour 2008!!!!!!
