She did have some health issues (see Big Fox Festival), but I think she wanted out long before them. Her heart didn't seem in it anymore for a while. Maybe it was the direction the band was going, maybe it was hostilities between the girls, maybe she thought it was below her to play opening gigs after headlining the Tokyo Dome before, maybe she didn't like how Su was the main vocalist, who the fuck knows. I think the health stuff was more of an excuses to get out of her responsibilities in the first place, her first step on the way out.
