Karas OVA

Summary: 

    Karas is set in a fictional version of Shinjuku, Tokyo.[1] The show initially showcased larger areas of Tokyo, but the production team felt other animations have featured these areas too many times.[2] Art designer, Hajime Satō (佐藤　肇, Satō Hajime?) created a modern version of the ward infused with a mixture of East Asian cultures. Chinese characters bearing the curves and stylings of the Korean language fill the billboards and signs. Western gargoyles and Singapore's Merlion statues decorate the streets, and the buildings are modeled on Shinjuku structures of 2003 while blending influences from the Shōwa period.[3][4] This Shinjuku is populated by humans and Japanese folklore spirits, yōkai. The humans have become indifferent to the yōkai's presence, and fail to see them as they go about their lives.[5]

The production team envisioned Japanese cities as entities, who require physical agents to execute their will and regulate the activities within them. The concept behind the health of a city is based on traditional Chinese medicine in which the smooth flow of a body's fluids nourishes its internal organs. The team equates yōkai with qi, humans with water, and agents of the city (karas) with blood. They integrated Celtic mythology into their concept for further symbolisms, treating the city as the male (yang); and Yurine (ゆりね, Yurine?), the manifestation of its will as female (yin). In contrast, their theory treats the humans and agents as the children of the city and its will, and classifies them as the reproduction system's five major organs. Following the team's vision, the mikuras (evil yōkai) represent the five elements in this system. This idea forms the basis of the relationship between cities and their inhabitants in the show.[6]
