http://www.cueme.me/2012/06/kisaki-urumi.html More pictures of her wearing even more revealing costumes and acting shamelessly.
She is one of the hottest cosplayers I've seen. However, she is more suited to become a gravure idol than a cosplayer. She's willing to take off as much clothes as possible and willingly shows many of her embarrassing parts like her panties for Mio's cosplay. She sometimes does this completely unnecessary like her cosplay for C.C, as she's wearing nothing below her waist while not wearing a bra either despite the fact that that is not C.C's trademark costume. Seems like she's just stripping unnecessarily to show off her body. Even when she's not directly showing off her body, she's suggesting it like her schoolgirl outfit. At #6, she's raising her skirt up and shows her ass. Then at #12, she's just sitting on a chair, spreading her legs as wide as possible. You can't see her panties because the chair is covering it, but she intended to arouse people that way.
Also, to her, it seems like showing her panties and bra (if she's wearing them at all) seems to be a given. She doesn't even bother much covering her body anymore like for #61, she's just blatantly took a photo with her nipple out and censored with a random flower. Her policewoman, Sheryl and Fujiko Mine Cosplays are slutty as Hell.
@ hooterboy: probably the tag is defining Kisaki herself. Her breasts are so huge that she is like a cowgirl. Her huge breasts can be especially seen at #11, #63 and #78. They almost look as big as her head. Must be heavy carry those things. She's also showing her breasts most of the time. Like #18, only thing she's wearing is the tiny bra she's holding with her hands.
