KiiiKiii released 404 (New Era) on January 26, 2026, the title track of their second EP Delulu Pack. The song runs on pulsing UK house and garage beats with rapped verses and airy vocals, and takes the "404 Not Found" error as a metaphor for freedom beyond boundaries. It was arranged by the British duo LDN Noise. The single reached number two on the Melon Top 100 and won on Show Champion, Music Core, and M Countdown. KiiiKiii debuted in 2025 under Starship Entertainment.
