Musical style and influences

Aoi's musical style has been influenced by her love of anime, as well as artists such as Evanescence, Slipknot, and Tomiko Van of Do As Infinity. She initially did not show her mouth on physical release images, only revealing her full appearance during a Niconico livestream in June 2012. According to her, this was to give her a "mysterious aura" and because she wanted to emphasize her eyes, which she described as "powerful". Speaking to the website J-Pop Go before her London concert in 2015, she explained how she believed she would have never been discovered had it not been for the internet, and how she believes that it can be used as a tool for her to "connect the world" and "make dreams come true".

Aoi's songwriting style is that, when producing a song that would be used in an anime, she would first read the original source material or the anime script, and for songs that would be used in games, she would first play the game or discuss the story with a producer. After this, she would write song lyrics that would take into account the feelings of the characters.

Aoi related the development of her singles "Memoria" and "Innocence" in an interview with Animate Times. She detailed how she always wanted to perform "light-conscious songs" even before she made her major debut, and that the theme of her early songs would be about "letting the light shine through your heart, even when times are difficult". "Memoria" was released at a time when she did not perform live as she still hid part of her face, and taking this into account, she wanted to make a song where emotions could be expressed through her singing as opposed to her mouth. For "Innocence", she wanted to produce a song that could express the growth and experiences that Sword Art Onlines main characters Kirito and Asuna were encountering.

For her first album Blau, Aoi wanted to express varying emotions such as "real sadness" or "fun expressions", as opposed to her previous releases, which described as mainly focusing on "singing with strength or sorrow". For example, with the song "Yume no Owari", she sang it with a thick voice to "allow her to sound like an adult".

For her single "Accentier", Aoi wanted to produce a song that had a theme of "seeking the light, no matter how dark it gets". The title of the single comes from the word "accent", as she wanted the song to be a song to "cheer people on" and give people "an 'accent' of happiness". Aoi had been a long time fan of the Digimon franchise and was very happy to be chosen to perform a song for it.
