Suigintou is the only Rozen Maiden with wings. In the manga, it’s explained that these wings are considered to be flaws, because it created cracks on her back. However, Suigintou is considered to be one of the most powerful Rozen Maiden dolls because she has no actual need of a medium to use her powers. She is also the only doll to have been defeated and revived three times.
I got this photo from Hung, the photographer’s blog. He has a lot of exquisite collection of cosplay photos, and I’ll be sure to feature more of them when I get the chance. Thanks for sharing them, Hung!
