Chrome, or “Nagi” as she is known in her previous life, had an accident while trying to save a cat, leading to the loss of her right eye and some of her internal organs. By a chance of Fate, Rokudo Mokuro finds Chrome while he was taking a stroll in one of his illusions. He creates illusionary organs for her, allowing her to live.
I found this cosplay while going through Flickr. 大吉(Agi) is the photographer of this cosplay. Thanks for sharing the photo with us!
