I want to know who is the 담홍색, 핑크 mermaid..?

LUCHIA:Lucia is the Mermaid Princess of the North Pacific Ocean, keeper of the 담홍색, 핑크 pearl, and the main character of the story. She goes up to land to 검색 for her pearl which she used to save a boy seven years ago. She is unaware of the danger in the marine world and of her real mission until she is told of them 의해 her "older sister", Nikora. She is characterized 의해 her simplicity and naïveté, but with having a strong will, typical traits of shōjo 망가 heroines. However, in the 아니메 she is portrayed as an almost defeneseless, helpless, weak and dependent girl, always needing help. Her idol form is 담홍색, 핑크 Pearl Voice. Of all the 인어 in the series, Lucia's mermaid form and human form contrast the most (Lucia has short dark blonde hair and brown eyes in the surface while having long lighter blonde hair and light blue eyes while at sea).

My answer is Nanami Luchia She is the leader and the 담홍색, 핑크 mermaid
