Pichi Pichi Pitch

Noel and her younger twin sister Karen are twins, both born on either side of midnight between Thursday, February 13 and Friday, February 14 in 1986. However, they were born on opposite sides of the world, with Noel being born in the Arctic Ocean and Karen being born in the Antarctic Ocean. Noel lived a calm life until the day her kingdom was destroyed by Gaito and his minions. Noel escaped, leaving her kingdom behind. While escaping, Noel met the mermaid princess of the North Atlantic Ocean, Rina Toin, whose kingdom had also been destroyed. For a while, they traveled together, until Gaito and one of his minions, Yuri, caught up with them. Gaito tried to trap Noel and Rina, but Noel sacrificed herself and told Rina to escape. For a long time after that, Noel was trapped in the depths of the ocean in Gaito's castle, locked away in a large glass tank. Karen went out to search for her sister after hearing of this.

In episode 50 of the anime, Lucia, Hanon, Rina, and Karen all went to Gaito's castle to rescue the captured Mermaid Princesses. Noel was rescued along with the Mermaid Princess of the South Pacific Ocean, Coco. After that, Noel and Coco joined the group and battled against Gaito with the song Kodou. Together, they all helped the Mermaid Princess of the Indian Ocean, Sara, realize her true feelings, and Sara joined them. With the help of Kaito and Hippo, the Mermaid Princesses defeated Gaito with the song Kodou and Noel safely returned to her now-being-restores kingdom.


In the second season, Noel is seen to be a gentle, kind girl who is much more mature than Karen and Coco but is still immature at times. She also seems to be a strong volleyball player, and likes to play matchmaker as well. Noel is seen as having knowledge of magic objects and places, such as the Miracle Bay.


Noel has a gentle and kind nature and is a bit shy. She loves to read books and is a good friend of Rina. At times she can be a bit bold, as when she clung to Nagisa in order to make Hanon jealous.


Noel looks a lot like Karen. She has the same height as with the same hairstyle; however her hair is dark blue instead of purple and has opposite side bangs with dark blue eyes. Her birthmark also is on the other cheek. She occasionally wears glasses. Early in the both the manga and the anime Noel had a different hairstyle the right side of hair went over her face

Forms and Aspects

Noel has three forms. Those are her human, mermaid and idol form.

Human Form


Noel's Human Form

In Noel's Human Form, her eyes are slightly darker than other forms. Her hair is navy blue and wavy, with a right parted fringe. In the second season, Noel is shown wearing glasses at times.

Mermaid Form

Mermaid Noel

Mermaid Form

Noel's Idol form

Noel's transformation form

Her mermaid form follows the trend of all the other mermaid princesses, with a deep blue strapless seashell bra, two white colored pearl bracelets around her right wrist and a band of the same color around her upper arms and two pearl bracelets around her tail. Her hair is in the same style as it is in human form, though it is far longer and her hair color becomes pale blue.

Idol Form

Noel 's 2 Idol form

Noel's idol form

Her Idol form, her Indigo (Aiiro) Pearl Voice is a short strapless blue dress with purple ruffles on the one side, it is above the knee with a light blue trim on the top. She also has white gloves and high heel boots with pale blue pearls on the wrist and ankles and Indigo cuffs that extend to her mid-arm and slightly below the knees. Adorning the back of her waist is a light blue bow on the back with dark blue ribbon to match the dress. A blue and purple barrette partly holds back her hair. Her idol form is very similar in appearance to Karen's idol form, which is because they are twin sisters.

In the anime, Noel shouts "Aiiro (Indigo) Pearl Voice" to transform.

In her idol form, like Lucia and the others, Noel can use her singing voice to get rid of enemies. Noel's voice matches her personality, calm, and soft. She is not shown to have her own song in the manga or anime, but instead she is usually seen singing along side Coco and Karen. In the manga, Noel has two different hairstyles. In arc one, her hair is middle parted, long and wavy. But when she makes her entrance in the second arc, she has a side fringe resembling Karen's, but on the opposite side.

  • Along with Coco, Noel is the only Mermaid Princess that doesn't have an image song, but many like to believe that 'Tsubasa', sung by her seiyuu (Ryoko Nagata) is Noel's image song.
  • All Arctic Mermaids – Noel included – are born on a Thursday. Noel is older than Karen by the minute separating Thursday, February 13 and Friday, February 14 – the years in which these two days are on Thursday and Friday respectively are 1975, 1986, and 1992. The first year is too early, and the last year is too late, so it is obvious the shared birth year for the sisters is 1986. That having been said, since the series starts in 2003, this means the translation is incorrect in the manga where Karen states in her monologue that she (and thus Noel) are eighteen; as such, when we see Karen for the first time, she and Noel are around seventeen and a half years old.
  • Noel doesn't have an episode centered around her like Coco and Karen do.
    • Coco had a major role in episode 12 of Mermaid Melody Pure (episode 64) while Karen has made multiple appearances in the original series.
  • Most people – especially translators – mistake Noel’s name as being “Noelle”, which is the female variant of the name, but "Noel" has also been used for females.
  • Noel, along with Coco and Karen (the latter only in the manga), are the only mermaids to have been a prisoner of Gaito.
  • Noel and Karen have many similar features due to them being twins, albeit these are mirrored.
    • Karen has a mole under her left eye and her bangs tend to part to her left, while Noel has a mole under her right eye and her bangs tend to part to the right. They also have similar idol forms.
