Thania Garcia and McKinley Franklin of Variety commented that on "Demons", "the track sees Doja trade in her pop sound that fans fell in love with on "Say So" for a more rap-centric aura".

[10] Jon Stickler of Stereoboard commented that "the trap-inspired tune deals in punchy beats and layered synths that provide a foundation to lyrics addressing the recent criticism about her personal life".

[11] Sal Cinquemani of Slant Magazine stated that "the three-minute 'Demons' kicks off with a heavy, distorted beat and menacingly looped string sample, further fulfilling Doja Cat's promise that her latest album will eschew pop for a harder-edged hip-hop sound".

[14] RGM additionally compared Doja Cat on "Demons", stating "at times, she sounds like Nicki Minaj, then channels Kendrick Lamar, and even takes on the persona of an irate teacher".

[9] After premiering at Cinespia in Los Angeles on August 27, 2023,[15] the trailer for the music video was later uploaded onto Doja Cat's official website,[16] revealing it to be directed by Christian Breslauer and co-starring actress Christina Ricci.
