Demidevil (stylized in all caps) is the debut mixtape by American singer-songwriter and rapper Ashnikko.

Ashnikko first teased the mixtape in a series of videos in which she is gradually turning into her "demidevil" alter ego.

[6] In early 2021, Warner Music Group's merchandise team accidentally shipped out orders including physical copies of the mixtape earlier than its February 19th release.

[7] A deluxe edition CD, adding two bonus tracks ('Tantrum' and 'Daisy 2.0'), along with a sixteen-page booklet, is due for release on September 6, 2024.

[15] The lead single from Demidevil, "Cry", was released on June 17, 2020, and features Canadian musician Grimes.

[19] "Slumber Party" featuring American rapper Princess Nokia was released as the fourth single on April 23, 2021, after achieving viral success on TikTok.

[24] El Hunt of NME wrote that Ashnikko's "first real body of work builds on the early hype, and draws from a far wider pot of musical influences than before: Nu-metal, pop-punk, The Neptunes-esque production tricks and campy musical theatre", and concluded that the record "shows that [she is] far more than a two-trend wonder – with a tank full of intriguing bangers that evade living under 'Daisy's formidable shadow.

"[12] Reviewing the album for AllMusic, Fred Thomas stated that "The project's ten tracks nicely mix Ashnikko's enormous personality and brazen confidence with infectious pop-trap production and hints of early-2000s nostalgia that range from subtle to overt.
