~Noel (ノエル Noeru?)~

Noel (ノエル Noeru^?)

Voiced by: Ryōko Nagata

Noel is the Mermaid Princess of the Arctic Ocean and keeper of the deep blue (i.e. 藍色, ai-iro) pearl. She helped Rina escape from the sea monsters, which led to her capture. She is calm, gentle, caring, and studious (as she sometimes wears glasses on land later in the second season of the anime). She is Caren's older twin sister by about a minute at the most. Noel cares deeply for Caren, the one that she had always wanted to meet. Her idol form is Ai-iro (Deep Blue) Pearl Voice.

• In the third volume of the English manga, ai-iro was translated as indigo, but deep blue makes more sense regarding the character's colour scheme; the colours may be based on the rainbow, but Lucia is pink, not red.
• Some refer to Noel's name as Noelle, because originally Noel is a male name, while Noelle is the female form, but the official English translation as well as the official Japanese romanization uses Noel.
