Karas: The Prophecy

In a futuristic Tokyo, humans and spirits are sharing the same living space without realizing it, thanks in part to the guardian raven Karas and his masters, who maintain the precarious balance between both dimensions. But when a former Karas named Eko decides to challenge the system by seizing control, it's up to the entity Yurine, who represents the will of the Japanese people, to secure the future for humanity.
