Naga Girl

This is Yuna the Naga.As a baby she was found by a human couple who took the infant in and raised her as their own.Despite the fact she is half snake,she acts like an ordinary teenage girl.Strangely,she does not realize she is so different.Knowing their unusual foster child would never be accepted by human society,the kindly couple keep her safe on their private island,where none know of her existance.
Tragically,her foster parents are killed during a storm while out boating,and the lonely girl is forced to leave the island she had called home for so long and intergrate with humans.They reject and fear her,even try to kill her,but a kind human boy and his guardian older sister take the girl in and treat her as a member of their family.
