Ningyohime 2001 - Aqua

Jinae and Jade-twin. Since they were together, when they were small, Jade always praise adults, being sociable and adults. Whenever an accident occurs, the one who needs to scold is always Ginae. For Jinae, everyone likes Jadae more than Jinae, from his father, Uncle, Aunt and School Sensei. For this he hates adults. So she met a pretty guy on the beach! In addition, he is the first one who is ready to hear the story of Jinae about the mermaids.
