I don't want to say goodbye...Until we meet again, stay well, Hippo-san!

–Yuri to Hippo, Episode 25

Yūri (ユーリ Yūri) is one of the antagonists in the first season of Mermaid Melody anime and Manga series. Her debut is marked on Episode 4.


Pichi Pichi Pitch

Yuri, was the third Dark Lovers hired by Gaito in order to capture the remaining mermaid princesses. She participated in the cataclysm of the following palaces: North Pacific, North and South Atlantic and Arctic Ocean castles.

Afterwards, Yuri, her teammates and Gaito attack in the city the mermaid princesses live either with help or individually. After some events, Yuri and Hippo accidentally start to have feelings for each other without knowing who they actually are. They drop their feelings for each other but these feelings slowly return in the end. Yuri and her friends sacrified themselves for Gaito in the last fight. She returns to her original form, a green fish and died with Gaito, her 3 friends and Sara.


After her death, she and all the dark lovers return by the wish Hippo did to see Yuri one more time. She also participates in the reunion of episode 91 and sings with everyone from the show.

Yuri has a childish personality. Although Yuri is loyal to Gaito, his continued treatment of her as a child leads her to a star-crossed relationship with Hippo, when in his human form. When Yuri hears a mermaid's song, she screams to stop. Her cry-baby/bratty attitude makes it sound like she gets tantrums listening to those songs. Yuri also has a tendancy to dress up like the Mermaid Princesses and imitate them as well, as seen in episode 21 and at the New Year Party episode. Yuri is overall devoted to Gaito and tries her best to capture the Mermaid Princesses in order to make him happy. Even though she sometimes argues with the other Dark Lovers, deep down she cares about them and considers them to be her good friends.

Forms and Aspects

Yuri has long green wavy hair with a red and grey frilly headband and bright green eyes. She wears a rather formal and long red dress with a lot of ruffles and black and gray trims.

Human Form

Yuri's Human Form is the form she takes to stay on land. She also uses this form to meet Hippo. In this form she has the same hair, eye color, and structure. Yuri seems to still be able to use her powers with ease in this form.

Water Demon Form

Yuri's main form is her Water Demon Form which she uses to battle against the Mermaid Princesses. In this form her outfit is almost always her default outfit, only changing once when trying to impress Gaito with a new look only to be rejected.


Yuri is a pianist and gets her powers from playing the piano, which does strange effects to her environment, such as hypnotizing humans who listen to it, or summoning sea creatures. Her music doesn't seem to have an effect to the mermaids, only that it is in bad taste to them. When her piano has enough volume, it can block out one or two mermaid's singing. It only works once, of course, during her first appearance, like with Eriru, but with the appearance of another villain is another mermaid to increase the volume of the mermaids' song.

But she mostly uses her piano to cause pain to mermaids and humans. Her piano can be used to cause pain or hypnotising humans and make them do everything she says (As shown in episode 4). She has also been shown singing some of the mermaid songs in episodes 39 and 91.
