Eriru (エリルEriru) is one of the Dark Lovers.


Another Dark Lover of Gaito. She is the most talkative Dark Lover.She likes to spin a lot and works hard to capture the mermaid princesses even though she doesn't often succeed.She isn't exactly very harmful usually when she is relaxed and happy.When she gets angry, her eyes glow red, her voice changes and becomes a bit deeper. and her hands are almost shaped like claws.

When she hears a mermaid's song like Legend of Mermaid, she spins around constantly, holding her ears in displeasure, and because she is spinning, her face emotion constantly changes, and so does the scream of her voice. Super Love Songs! can have an interesting effect on her.


Eriru acts in a very taunting but silly manner towards everyone. She can be quite evil sometimes.But she tends to be silly most of the time.

Eriru has a multiple personality disorder,when she spins, she changes to a different personality. Eriru's usual personality is very cute,she would have pink blush marks on her cheeks and is not very harmful.

But when she is fighting with the mermaid princesses or angered,she changes to her evil personality.Her eyes turn red,her voice deepens a bit and her nails become more sharp,basically getting claws.

She also has another personality that doesn't appear very often in the show.Her eyes look more normal,and she acts more serious and is more observant of her surroundings.


She wears a brown tank-top that covers only her chest, a brown skirt, a yellow bandana on her head and purple high-heels. She has cat-like ears, brown hair, pink blush, and black wings. The color and shape of her eyes depends on what phase or personality she's in.

Human Form

One of Eriru's forms are her Human Form which she and all the other Water Demons and Mermaid Princesses use to travel on land. She needs her human form in order to look natural without any of her unusual hair or eye color being noticed. However, as a human, she can still use attacks.

Water Demon Form

Eriru's Water Demon Form is her main form which she uses to attack the mermaids. In this form , she has black wings and brown cat-like ears. She wears a tank top that only goes to her chest and a miniskirt with a belt, along with purple high heels and a yellow bandana.


In her Water Demon Form, Eriru attacks with black, wavy, energy arrows. She can also manipulate solid objects with her shadow-like powers and create whirlwinds with her spinning. She can control fish and use them as spies to spy the mermaids and know wherever they are too. If she spins in sand she can dig 4 meters down.

The rag or bandana on her head can be used to protect her cat-like ears from the mermaids' songs. However,this was only done in episode 2.
