You're Under Arrest AI Dance is the AI version of ILLIT's "You're Under Arrest" dance challenge. From one photo, you, your pet or a character dance the challenge with the song, without learning the steps or filming yourself. People also call this trend ILLIT's Under Arrest challenge, the Under Arrest dance and the 체포하겠어 challenge.
The song "You're Under Arrest" (체포하겠어) is the title track of ILLIT's fifth mini album, BREAK EVEN. BELIFT LAB released the track on October 26, 2026, together with its music video, which passed 28.5 million views on YouTube by November 13, 2026. The song is electro-pop with a whistle hook, and it won its first music show on November 6, 2026.
ILLIT teased the challenge on TikTok on October 5, 2026, reaching 4.9 million plays. Fans started dancing it on October 16, before the song was out. ILLIT's own challenge video of October 18, 2026 passed 12.5 million plays and 2 million likes. Fans mostly dance it solo in their own clothes. People know the dance by its signature moves: the point straight at the camera like making an arrest, the knee lifts, and a hand to the lips like blowing a whistle.
Every video runs for 15 seconds in one continuous shot from a still camera low on the floor. The dancer stands in full view from head to toe in a bright white room in daylight. The routine starts with a finger raised beside the face, rolls into marching knee lifts, throws one arm up high to point, and hits a wide stance with an open-palm shrug. Next comes a hand to the lips like blowing a whistle with a hip sway, side kicks, and a final shrug with both hands up by the head. Every move lands directly on the beat of the song.
Seadanse builds this full routine and the song into our You're Under Arrest AI Dance. You upload one photo of yourself, a cartoon, anime or game character, or a pet like a dog or a cat. The dancer keeps the face, hair and outfit from your photo. You receive a 15-second vertical 9:16 MP4 made for TikTok and Reels at 720p or 1080p.
