Over the past few years, rumors have circulated in Japan about the existence of arctic Humanoid Lifeforms inhabiting the icy waters of the Antarctic. These so-called "Ningen (人間, "Ningen", meaning "human") are said to be completely white in color with an estimated length of 20 to 30 meters. Eyewitnesses describe them having a human-like shape, often with legs, arms, and even five-fingered hands. Sometimes they are described as having fins or a large mermaid-like tail instead of legs, or even tentacles. The only visible or identifiable facial features are the eyes and mouth.
