Her top is composed of a matching blue, black and white Yukata which is a kimono made with straight seams and wide sleeves, a traditional black Obi, and high black Geta which are sandals with an elevated wooden base held onto the foot with a fabric thong to keep the foot well above the ground.. She owns two fins on the sides of her head and a fish tail to her back, as the original Jinmengyo's myth, she wears on her head a mask that take the form of a fish face.

In Real Life

The jinmengyo (じんめんぎょ jinmengyo, lit. human face fish) is a Japanese cryptid characterized as a carp which has the face of a human. While the concept had existed much earlier in art, the cryptid experienced brief popularity in 1990[1], when a photograph of a supposed jinmengyo was sent in to the Japanese tabloid magazine Friday (フライデー furaidē), starting a minor fad. The fad caused many to visit the location of the sightings, which allowed the area to capitalize on the fad and sell jinmengyo-themed merchandise and food. During this fad, jinmengyo were also supposedly found in Korea. Later, in 2005, Jinmengyo were supposedly spotted in China and Korea, with Korea even reporting the sightings on television.

Though true jinmengyo are merely fantasy, the phenomenon of carp having the appearance of a human face is real. Some varieties of koi have been known to have the appearance human-like facial features when seen from the front, despite lacking a true human face. In nearly all cases, this is not due to a facial deformity, but caused by the arrangement of the markings on the carp resembling human facial features such as front-facing eyes, a nose ridge, or a mouth. In fact, this occurrence is not only possible, but far from rare. In 2010, woman spoke to the Daily Mail, a UK-based tabloid magazine, who published an article on a human-faced ghost koi, which lead to a response by Practical Fishkeeping, an aquarium-focused magazine also based in the UK.[2]
