Am I the only one that thinks it looks alright? I like it better than her straight across bangs she had earlier this year. And besides, it's not like having long hair was a majorly defining part of her image. Maybe if Sayu went and chopped her hair, I'd be shocked.
I think it kind of reminds me of around 1998-1999 when Morning Musume had about half of its members with short-cropped hair. At least she picked a more mature hairstyle instead of going backwards to her 12-year-old pigtails.
