"Even if I lose my "voice". Even if everyone else doesn't turn up to hear me sing — as long as you're there, then, that's enough. If it comes to that… I will sing, just for you.” - Miku Izayoi, to Shido Itsuka
Miku Izayoi (誘宵 美九いざよい みく, Izayoi Miku) is the sixth Spirit to appear who was, like Kotori, originally a human that gained the power of a Spirit around the same time Shido first met Tohka.
Appearance[]
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.
Personality[]
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."
Relationships[]
Shido Itsuka[]
Due to her past, when Miku first met Shido, she has great dislike towards men, seeing all of them as depraved and perverted who only hypocritically liked her and sees Shido as no different and would attack Shido on sight. Because of this, Shido was forced to crossdress as a girl (renaming himself as Shiori) to get closer to her which piqued Miku's interest.
However, upon finding out that that "Shiori" is actually a guy, Miku was extremely angry towards this and her hatred towards Shido worsened. Eventually, when confronted by Kurumi and Shido, Miku remained stubborn and could not believe Shido truly cares about Tohka and she even mockingly offered Shido a harem of girls with her powers if Shido admits that he was just pretending to be a hero.
Miku's attitude towards Shido (and men later on) soon changed when Shido revealed her past and even defended Miku from Inverse Tohka's attacks, and Shido's promise to protect her and be her fan no matter any circumstances ultimately fell in love to him and allowed him to seal her.
After being sealed, Miku clings to Shido at every opportunity and calls him "darling" affectionately and would often try to flirt with Shido even at public places. Although Shido reciprocates the feelings, he nonetheless noticed that Miku has been behaving a little bit childish when they interact. Miku also actively tries to make Shido crossdress as Shiori as well much to the latter's disapproval.
Tohka Yatogami[]
After being sealed, while taking a liking to all the Spirits, Miku took a particular liking towards Tohka, taking every opportunity she can to hug her, much to Tohka's annoyance and embarrassment.
Natsumi[]
Miku was initially scared of Natsumi because she was intended to seal her away into Haniel and separate her from Shido. However, she still came to her aid when Ellen attacked her and later helped with her makeover. After being sealed, Natsumi became a regular target of Miku's yuri tendencies.
Origami Tobiichi[]
Out of all the AST members, Origami caught Miku's eye due to her looks. However, she was disappointed by how she immediately tried to attack her. Still, Miku kept having a liking to Origami. Even after she tried to kill her, Miku didn't seem angered by it, although she did claim there were a few "things" she wanted to do to her. After Origami was sealed, Miku was the only Spirit who wasn't shocked by her uncharacteristic gratitude and immediately welcomed her.
