Hanon Houshou is the secondary main protagonist from the Mermaid Melody: Pichi Pichi Pitch anime and manga.

Hanon is a flirty, carefree, all-around girly-girl that befriends Lucia on her first day of school. She's more serious than she looks, however, and has been watching Lucia for days and confronts her with her true identity at the end of the first chapter. Hanon is actually the Princess of the South Atlantic Ocean, otherwise known as Aquamarine Pearl Voice. With her strength and happy nature, she makes a great first ally for Lucia, even though they're always at each other's throats — in particular, Hanon doesn't approve of Lucia dating Kaito at first, even though she's all over a human man, who, at that, happens to be her own teacher. Again, though, despite her peppy, fluffy, hypocritical image, Hanon feels tremendous guilt for the fate of her kingdom, which was besieged with her as the only apparent survivor.

In the AWA fics, Hanon is a student at the AWA Academy and is part of Class 5.


Hanon has brown eyes in her human form, but she has aqua blue eyes in her mermaid form. Her human form has short dark azure hair, she has long light blue hair in her mermaid form. She always wears a blue shell necklace around her neck containing her Aquamarine Pearl.

Hanon's main form is her Mermaid Form. To stay on land, Hanon needs to use her Human Form and is able to switch from both forms back and forth by getting wet or drying herself. To transform into her Idol Form, Hanon shouts out Mizuiro Pearl Voice using the power of her pearl to ward off enemies.

Her human form is significantly different from her mermaid form. Hanon's long aqua hair has the same hair style, but becomes shorter and grows darker. She also has brown eyes in her human form. She usually wears a barrette shaped like an 'X' in her bangs, and she is seen in many outfits. She is the second shortest mermaid princess after Seira.

When in her mermaid form, Hanon has long, wavy, blue hair with two stars in her bangs. She wears an aquamarine clam-shell bra, and a bracelet around her upper left arm. On her darker blue tail, and on her wrist, she wears double navy blue pearl bracelets. She wears a shell locket containing her pearl around her neck just as she does in all her forms, and star earrings.

Hanon transforms into her Idol Form, Mizuiro Pearl Voice, so she can defeat enemies with her songs. Her idol form consists of a short light blue strapless dress, with gloves and boots to match it. The dress is light blue and the skirt is sky blue with three layers and ruffles. Her gloves and boots are baby blue with pearl bracelets on her ankles and wrists. She still wears her star barrettes, earrings, and like all the other mermaid princeses, her shell necklace. 

In the second-half of the series, Hanon, and get new upgrade outfits by the sea goddess, Aqua Regina, making them even more elaborate. Her boots and gloves now have an extra layer and there are ruffles on her top piece. The bottom two layers of her skirt are a lighter shade of blue and the top layer stays the same shade. Her hair grows longer, darker and much more wavier. Hanon does not gain another accessory like Lucia and Rina, but still keeps her star barrettes. 

Hanon and Lucia's Idol Form are very similar with a few slight changes. As it is true with all the mermaid princesses, Hanon's second transformation is more powerful than the first one and enables her to defeat the Black Beauty Sisters with her new songs.


Hanon is a kind and friendly mermaid, but acts much more different when it comes to boys. At first, she thought it was wrong to love humans, but after falling in love with Taro Mitsuki, she changed her mind. Hanon is a love expert when it comes to boys and is obsessed with fashion and make-up. She also loves to shop.


Like the rest of the mermaid princesses, Hanon 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 is transmitted by a microphone like object called the E-pitch and is used to defeat the enemies.

She says "Love Shower Pitch" in the anime, whereas in the manga she says "Pretty Sugar Pitch!" in order to defeat enemies.


  • Although Hanon is not the youngest mermaid, she is the second shortest one after Seira.
  • She was born on a Wednesday.
