KiiiKiii have unveiled a special music video for their latest title track.

On February 6, the group released the special MV for "404 (New Era)," the title track from their second mini-album Delulu Pack, via their official YouTube channel.

The video drew attention with its playful title—"(No Re-uploads) We Shot Our Own 404 (New Era) MV lol KiiiKiii"—hinting at a distinctly different mood from the official release.

Composed entirely of footage filmed by the members themselves, the MV highlights a relaxed, self-shot camera style. Low-resolution visuals and webcam-style logos evoke a strong Y2K aesthetic, amplifying the Gen Z sensibility.

"404 (New Era)" is a UK house–inspired track that reinterprets the error code "404" through its lyrics. Addictive beats and punchy rapping come together to create a bold, high-energy sound.

With this release, KiiiKiii set a new personal best. As of 9 a.m. on February 7, "404 (New Era)" ranked No. 5 on Melon's Top 100 and claimed the No. 1 spot on the Hot 100 chart.

Meanwhile, KiiiKiii are scheduled to appear on Show! Music Core on February 7.
