Miku is a Spirit and an idol. She hates men to the point that Shido even had to cross-dress in order to interact with her. Her Angel, Gabriel has the ability to manipulate and brainwash people. She took an interest in the undercover Shido because he wasn't affected by her hypnotic powers and challenged him to a contest in which that if he lost, he would have to transfer to Rindouji. The challenge was for who would earn the title of being the best school. There was a singing contest which was later won by Miku, but the title of best school was won by Raizen High School.
Being defeated by Shido at her own game, she initially rampaged, using her powers to break the rules and simply take what she wanted, despite her being the one to first issue the challenge (and despite her frequently cheating to win). During the course of this, she took control of the other Spirits, discovered Shido's true gender, and tried to have the entire city to kill him. However, after Shido and Kurumi muscled their way to her and asked her to stay out of their way while they rescued Tohka from DEM, she took an interest in Shido (she had initially believed no man would ever save anyone for any selfless reasons) and asked his friends what their relationship was.
She then appeared to help Shido and battled with him against DEM, however, she claimed that her only intent was to add Tohka to her collection of Spirits. She repeatedly tried to prove that Shido was selfish, adherent to her view of all men, by trying to offer him all the girls he wants if he gives into his fatigue and gives up his rescue of Tohka. She's further shocked when he refuses and eventually is even visibly shocked when Ellen nearly kills Shido. It becomes evident that Miku can't give up her powers because that would mean she's returning to her human past, which is itself quite a tragic story, and because she is secretly scared of humanity, which caused the psychological trauma that made her unable to sing in front of people. She finally changed her mind when Shido upheld his earlier promise to protect her and shielded her from Dark Tohka's power. She is also moved, although initially shaken when Shido promises her that even if the entire world turns against her, he alone will remain her fan.
After this, Miku decided to let Shido seal her Spirit mana and move on with her life, even appearing openly in public as an idol. She has shown great love and affection towards Shido and constantly calls him "darling."
Miku, as an idol, is without a doubt a beautiful girl. She has a voluptuous figure and smooth skin that has never missed maintenance. She has long hair with a bluish purple color, while the color of her eyes is light indigo. Miku's height is stated to be 165 cm, and her three sizes are B94/W63/H88.
Her Astral Dress is mainly yellow with blue and white ruffles covering some parts of her dress. She wears a yellow moon hair clip with a flower connected to the curve ends of the moon. White flowers and petals can be seen next to the moon hair clip. She also wears a choker on her neck with a white lily attached on it.
While at school, she wears a deep blue sailor outfit as well as a yellow flower petal hair clip that resembles the one she uses when wearing her Astral Dress.
Miku harbors a strong hatred towards men and treats girls as servants fit to serve her, which is why she transferred to an all-girls school, Rindouji all-girls private academy. Due to her past, in which people that were once her fans (mostly male) accused her of scandals in the past that were not true, leading to her losing her voice from the pressure and caused her to almost commit suicide. Even her opinion of women was initially poor, seeing them as replaceable servants at best and not caring if they died, even believing they should be happy to die for her. Her coldness was to the extent that even Shido openly admitted he hated her.
She is very flirty, both before and after warming up to Shido, she expresses this towards most women who fit her type (and Shido) and is very blunt about it. After warming up to Shido, she doesn't hesitate to flirt with both him and the other Spirits and does not even mind Shido having a harem, in fact, she pretty much encourages it. Miku also does not show any more of her previous arrogance, while no longer hating men, she still prefers to be by her female fans more, and she no longer treats women as servants and effectively gave up her power to control people when she was sealed. Shido describes her current personality as being "very childish."
Just like Kotori, Miku was a normal human before she became a Spirit. Ever since she was little, Miku loved singing. She wasn't good at studying or sports, but she could sing better than anyone else around her. As an aspiring singer, she had always dreamed of performing on the big stage. That dream came true when she debuted as an idol singer at the age of 15 under the stage name Tsukino Yoimachi. It was the best thing that Miku could have wished for, doing the very thing she loved and being adored by her fans.
Her career, however, came to an abrupt end just after about a year when she refused to sleep with a hotshot TV producer. Before Miku knew it, false scandals about her began to appear and she soon fell out of favor with her agency along with her fans beginning to hate her. Miku thought that she could reconnect everything back with her singing, but then suddenly lost her voice.
As Miku contemplated suicide, Phantom appeared before her and turned her into a Spirit. Afterwards, she used her spirit powers, regained her lost voice, and debuted again using the name Miku Izayoi. She became famous due to her voice that was known as 'sound anesthetic' and released several super popular tracks. She also weaved her powers into her songs to make people who listened to them slowly forget the person known as Tsukino Yoimachi. However, she never appeared in magazines, television, or any public media. Miku held only private concerts and the only ones who were invited were her loyal female fans due to her hatred for men.

Powers and Abilities
Miku's "Angel" takes the form of an organ that can be used to hypnotize people as seen when she used her Angel to control the Yamai sisters, Yoshino, and the audience. It has been implied that she cannot usually hypnotize Spirits, as when she tried to hypnotize Shido and failed, she thought that he could be a Spirit like her. Likewise, both Ellen and Kurumi have also shown a resistance towards her mind control songs. It should be noted, however, that she managed to control the Spirits that Shido had already sealed without any difficulties. Miku can also fight using her voice as shown when she attacked Shido with a sonic wave. She can also use her powers defensively, as shown when she created a shield to protect Shido from Tohka. For her convenience, <Gabriel> could also manifest as smaller organ pipes, which she can use on smaller crowds.
Four different applications of her Army Breaker Diva have been demonstrated so far:
- March [行進曲（マーチ)] : Enhances the listeners' physical strength.
- Rondo [輪舞曲（ロンド）]: Primary method of defense and can be also used to restrain others as well. However, it failed against Tohka when she was in her Inverse Form.
- Solo [独奏（ソロ）]: Brainwashes the listeners. Solo does not appear to be capable of altering people's memories. Although it can mess with its victims' perception of Miku and make them extremely devoted to her, it doesn't affect their existing views on other people. Even under Miku's control, the Spirits still thought very favorably of Shido. But as long as they stayed brainwashed, they would prioritize their actions according to Miku's orders and well-being above anything else. Being sound-based, Miku's power works very effectively through speakers. Broadcasting her concert live was how she managed to put almost the entire city under her spell in Volume 7. But as shown with Tohka, a pair of ear plugs are able to block out the sounds and makes the wearer immune to Miku's powers.
- Requiem [鎮魂歌（レクイエム）] : A relaxing song that has an analgesic effect.
- (To Shido Itsuka) "I------Lost it. Once. Because of those ugly males, I lost my voice because of a psychological disorder-----the voice……the voice more important than my life………..!" 
- (To Shido Itsuka) "… You kept our promise. If it's you, there's no problem. Only you…I can trust." 
- (To Shido Itsuka) "Thank you…very much, darling…I love you!" 
- (To Natsumi) "Think about it, Natsumi--------about the fact that a girl can [Transform] without using an Angel." 
- (To Nia Honjou) “Then, let me show you Nia-san. The power of woman you didn’t know about. And be sure to carve this inside your mind. My name------Izayoi Miku!” 
- Her former stage name was Yoimachi Tsukino.
- Miku has the character for "Nine" in her name (美「九」). It refers to the ninth Sephira on Kabbalah's Tree of Life: "Foundation."
- Her angel Gabriel's name means "The Strong One of God" or "The Strength of God."
- Gabriel also represents the moon in the Sephira.
- Miku's Astral Dress's name is 'Shaddai El Chai' which means 'Almighty Living God'.
- The "Lily" in the title of Volume 6 cover means "yuri" in Japanese or "girl to girl relationship". This is referencing how Miku hates men and prefers girls, with Shido being the exception.
- Miku refers to Phantom as 'God'.
