She wears black sunglasses and has a barcode tattoo under her tear bag. She has jagged shark teeth. She wears grey tassel earrings with gold hardware, a black dress shirt, a white vest, and black trousers. She is always smiling.
[Overview] A woman with profound knowledge in mathematics. Because her way of speaking changes constantly, it often feels jarring to talk to her. She claims it's for the sake of acting. If asked about her profession, she replies "White Chocolate." If you try to scan the barcode on her cheek, only a mysterious string of characters appears. She is a genius at mimicry, but otherwise a brilliant and hardworking person. She occasionally speaks with a regional Kansai drawl, especially when she's excited or high-energy.
[Sample Voices] "I'm Mk-III. Nice to meet ya, okay?" "I'm just a cute little thing, so I wouldn't know about that~ โก" "Personally, I think you should stay away from that, buddy." "Eh... that's not my fault, is it now?"
To Enemies: "...I have no intention of returning to you." "I'm sorry, but you'll have to give up. On me, and on that child."
??? "...'Refko'. The precious name my mother gave me."
