The story revolves around Juuzawa Juu, a notorious delinquent at his school. Then suddenly out of the blue, a quiet girl calls Juu out and tells him that he was a king in his previous life and she was his faithful knight.
[Spoiler]
As the story progresses a scene is shown at the end of the first episode in the OVA, indicating a memory of Juu when he was a kid. In this memory, Juu was probably in grade school. He seems to be all beaten up like he had just got out of a fight. Juu saw a girl crying in a park. Juu approaches her and pat her on the head as a sign to comfort her. He then sat next to her and pulled out a toy that is dress as a king. This strongly indicated that Ame's memories of this "Past Life" must have been caused by Juu himself when he was a boy.
