KiiiKiii, the girl group launched by Starship Entertainment in 2025, released the video for “404 (New Era)” on the label’s YouTube channel in January 2026. The track comes from the group’s second EP, Delulu Pack.

Internet slang as an album title

Two of the words attached to this release come straight from online English rather than from Korean. “Delulu” is a clipped, deliberately silly form of “delusional” that spread through fan communities before reaching wider social media; “404” is the HTTP error code a browser returns when a page cannot be found. Korean agencies have grown comfortable naming releases with this kind of borrowed net vocabulary because it needs no translation — an overseas listener recognises it instantly, and the hashtags work identically in every market. The Korean title 뉴에라 is simply “New Era” written phonetically in hangul.

About this release

“404 (New Era)” belongs to Delulu Pack, KiiiKiii’s second EP. The video was published on the STARSHIP channel, the agency’s main upload point for all of its acts rather than a group-specific account. The official description lists only hashtags — the group name in Roman and Korean script, the song title in both, and the EP name. No production or writing credits were given there.

Watching from outside Korea

키키 is the Korean spelling of KiiiKiii, though the same syllables can also be used as a laughing sound online. The artist and EP or song title distinguish the group’s release; watch the clip on this page.
