Cristina turned into a mermaid, and Esther who was left to raise her alone, had to release Cristina into the sea, because of the superstitious villagers.
Cristina became known as Marina amongst the mermaids. Still remembering her human years, she dreamed of being human again. Marina traded Istah necklace for her legs with a sea witch Dugong. However, Marina soon discovered that when the moon is full, she becomes a mermaid again and that only true love's first kiss can free her from the curse.
