Lunar Edomae (江戸前 留奈 Edomae Runa ) is a childhood friend and rival of Sun. She has used the powers of her mermaid voice to become an idol singer.
Lunar is a beautiful looking young girl with pink hair and eyes. She is commonly seen wearing her Isono Junior High School uniform and just like Sun, if she were to get water spilled on her legs, she will turn into her mermaid form, needing to be dried off to return them to normal.
She seems to suffer from a superiority complex, and she never passes up an attempt to overshadow Sun. Lunar has a trademark laugh that can be heard before she enters the scene. Despite the rivalry that she has with Sun, the two really are friends. Lunar became a pop idol partially due to a sense of rivalry with Sun caused by the above-mentioned nature, but her true feelings was that she wanted her mother, who abandoned her when she was 5 years old, to see her on television.
An interesting aspect of Lunar's personality is that she often refers to herself using plural pronouns. She even does this while talking to herself inside her head, though why, exactly, is unclear.
Lunar controls her own personal body guards made up of the boys of Isono Junior High school, she often calls them in to defend her. She uses her personal body guards like her own personal army. They are currently at war with Sun’s body guards.
She initially thought that Sun was boasting Nagasumi to her, and in an attempt to outdo Sun she decides to steal him away from her by making Nagasumi her servant, since Nagasumi has also seen her mermaid form. Later she decides to live in Nagasumi's house until his servant status is over. It was unclear if she has developed a liking to him (since she has decided to learn how to cook and make him a packed lunch, although still in an attempt to beat Sun). However, it is then revealed that she does in fact have feelings for Nagasumi, and planned on marrying him, but this is stopped by Sun. Even after her wedding was canceled she continued living with Nagasumi.
Powers and AbilitiesEdit
Like all mermaids, she has a fear of cats (ailurophobia). Lunar also uses her mermaid singing voice to gain popularity as a singer. Just like Sun she can also manipulate others depending on what song she chooses to sing, her song of war can move people to turn against one another and fight anyone in their path. She also has an ultrasonic scream (similar to Sun's) that is powerful enough to cause damage to anything around her and stun her opponent. She can transform between her mermaid and human form to blend in with humans.
