Lucia's Clothing #3 (Mermaid Form)

Lucia has dirty blond hair tied in pullbacks in her human form and bright blonde hair tied in pigtails while as a mermaid or in her idol form. She also has brown eyes in her human form but blue eyes while as a mermaid or an idol. She usually wears a Pink Necklace shaped like a winged sea shell that contains her pearl.

Forms And Aspects: As a mermaid, Lucia has to transform into a human in order to stay on land. When she is facing a sea demon, she transforms into her idol form Pink Pearl Voice and uses her voice as offensive attack. The Sea Demons and enemies are hurt by the frequency in her voice as well as emotions the song contains, which are generally of hope and love.

Human Form: Lucia’s mermaid form and her human form contrast the most out of all the mermaid princesses. She has short dark blonde hair and brown eyes while on land and long lighter blonde hair in pigtails and light blue eyes as a mermaid. She's mostly seen wearing a pink and red sailor style school uniform. Also, her human form is differnt from Hanon and Rina: She turns human because of her dream of being human, but Hanon and Rina only turn human to escape from the demons.

Mermaid Form: Lucia’s mermaid form is the same as every other mermaid princess, with a bracelet around one of her upper arm and double pearl bracelet around one of her wrists and her tail. Their all different colors. Lucia's mermaid princess form is first revealed in chapter 6 of the manga and episode 13 of the anime. Her hair is loose and barely in pigtails the tips of which have been loosely curled. There are also glittering pearls and flower petals strewn throughout her hair. She wears lacy elbow length gloves, and her dress has three bows in the center as well as three layers of cloth, all centered in the front. Lucia appeared two more times in this form, in chapter 14 and chapter 19 of the manga with minor differences, such as adding a choker of laces and changing the petal flowers into roses.

Idol Form: When facing the enemies, Lucia transforms into her idol form, Pink Pearl Voice. In her idol form, she sings with the rest of the mermaid princesses to defeat the enemies by singing songs that convey their true emotion. Her first outfit is complete with a pink dress with short skirt, lacy pink gloves, and boots. Lucia, along with Hanon and Rina, gains her second outfit in episode 28. The trio was upgraded by the sea goddess, Aqua Regina. Her second outfit is very noticeably different from her first one. Her dress now is complete with a double layer and a long pink bow on the back. Her gloves and her boots now have a second layer. She also gained accessories such as a jeweled headpiece, a more intricate bracelet, and pink accents alongside the top part of her dress. Lucia and Hanon have a similar with slight changes to the design. It should be noted that their transformations are based off of the general format of their school uniform. As it is true with all the mermaid princesses, Lucia’s second transformation is more powerful than the first one and enables her to defeat the Black Beauty Sisters with her new songs.

Age Ceremony: When Lucia returns to her kingdom for her ceremony in episode 13, her long blond hair is wavy and curly and still in pigtails. Her shell bra is pink with red gems on it and a triple layer skirt with three red bows in the front.


Like the rest of the mermaid princesses, Lucia needs her pearl in order to transform into her idol form. Her pearl is also needed in order to summon Aqua Regina. When in her idol form, her voice was transmitted by a microphone like object called the e-pitch, in order to defeat the enemies. Her voice is shown to be very powerful. She is also shown wearing Aqua Regina's outfit in the last volume of the manga. Her hair is loose. She also holds Aqua Regina's staff. Legend of Mermaid was a song that she would sing as child, so this is one of her image songs.

Her character songs are 'Splash Dream', 'Legend of Mermaid and 'Koi wa Nandaro'. She ends attack songs with the phrase 'Love Shower Pitch' in both the anime and manga followed by 'Encore wa ika ga' which can be translated as 'How about an encore'?


First Transformation: Edit

Lucia calls out "Pink Pearl Voice" indicating the initiation of the transformation. Her pearl begins to glows and it comes out of her pendant, turning into her microphone. Then Lucia's pink boots and gloves appear. She takes her microphone in her right hand and twirls around and strikes a pose.

Second Transformation: Edit

In the second transformation, Lucia calls for her pearl again, but this time, it shows her whole self, and is 30 seconds long. She glows, changing shape, and after that, when the light stops glowing showing her newly transformed self, she sometimes does the upgrade, but she sometimes doesn't. The upgrade in the second transformation shows the added parts glowing when they are seen added.

Upgrade: Edit

After Aqua Regina gives Lucia, Hanon, and Rina the upgrade in outfits, Lucia can transform into her second idol form. Her new top appears then her skirt, each with an extra layer. Her boots and gloves appear, also with a new layer. A notable new accessory is her long, dark pink bow tied at her waist and her headpiece.
