1. She probably doesn't chart because she's not heavily promoted like the big acts around. Also as evolusean mentioned her genre is outdated in Japan so few people are bound to buy the releases either.

Finally I believe she's not exactly seeking a heavy schedule in music due to the fact she has many more other activities. As Petit mentioned, sifow is more interested in spreading her lifestyle. She's planning to open a school, has a company and a clothes outlet. She's pretty busy so probably her avex career is just another of those activities to enhance her gal mission. For her getting with avex was pretty lucky since they rarely kick off artists like certain record labels.

3. I think her image probably doesn't help much as evolusean again mentioned. Many people don't consider gals seriously and are more bound to overlook her more. Plus the music industry is full of newcomers and most people would choose a "normal" artist over sifow's gal image.
