Rina Toin

Rina Toin is the third mermaid princess to appear in the anime. She was a transfer student and is the most mysterious of the three.

Personality
Rina has a very serious and fearless personality. At the beginning of the anime, she is seen as a loner, but later warms up to Lucia, Hanon, and Kaito. Because of her "cool attitude" and beauty, she is admired by all her classmates. She is haunted by the incident of her palace being destroyed and Noel being captured, and has trouble telling people about her problems.

Unlike her two friends, Rina's love is focused on the T.V., specifically on comedy shows. Rina always shows that she is not interested in love, considering she turned down a group of college boys in episode 16. Up until the pure season, Rina is prone to blushing and stuttering around her boyfriend Masahiro. In the end, Rina blurts out that Masahiro is the most important person to her.

Appearance

 * Human Form: Rina has waist-length dark green hair and grey eyes. Rina is hardly ever seen wearing anything girly or short and is first noticed for wearing the boy's school uniform instead of the girl's uniform. Rina's wardrobe is plain and casual, yet elegant and cool.
 * Mermaid Form: Rina's green hair appears to remain the same color and length and her eyes are green. She wears a green shell bra and her tail is green.
 * Idol Form: Rina wears a long green dress with an opening on the left side of her dress. She has frilly green gloves and heels and her dress has a green bow and sash around her waist. She gains a beaded headband and her microphone.

Powers
Like the rest of the mermaid princesses, Rina 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. She has two image songs from both seasons of the anime: 'Star Jewel' and 'Piece of Love'. In the italian dub, her song is 'Stella Preziosa'.

It is currently rumored that Rina has been loosely based on real world superhero, The Bird (Halifax, Nova Scotia, Canada).
