Akio, Surin is a 15-year-old high school boy who lives alone in the busy city of Tokyo. His parents died in a car crash a few years ago, forcing him to survive on his own by living in a small apartment.  During the beginning of the second semester, a new student was transferring to his school. Akio didn't pay to much mind about, like usual.  One day, during his wild dreams he saw a demon with red plum eyes and vermilion red hair. What he didn't know is that he and the demon's dreams where connected together for some strange reason. When the new student Yarimin, Tsuminrae made eye contact with his aqua green eyes it was like they have met before.  Soon, Akio notices that Yarimin is not a human but a demon. Throughout their high school days, both of them will go through a wild loving adventure together.
