Singing was just a side project. She never intended to become a major artist at all. If sifow wanted to become bigger, I'm sure there would of been like more effort shown.
sifow's target audience are the CLEAN gals. Ganguro/GALS's, have a very negative have a very negative perception from people, and sifow being one didn't really help at all.
GAL REVO (inc sifow) company are her management team, and they are the ones in general that do all that promoting. Since GAL REVO, is probably founded by sifow's very own funds, I'm sure their budget was at bear min.
I'm sure AVEX won't drop her, they have a contact, and sifow has mostly likely discussed what kind of artist she would of wanted to be, low key, Shibuya exclusive probably.
But since Kumi's pop is like slowly fading due to her "naughty" comment, i really wish they pimp out sifow soon! lmao. I'm going to re-purchase all of sifow's CD's when im in Shibuya lmao

and hunt for sifow and pray she is in RE-CLA ya lol. And ill take pictures
