Delulu Pack

The record

Delulu Pack is KiiiKiii’s second mini album, released on 26 January 2026 with six tracks. The title track is ‘404 (New Era)’, and the earlier single To Me From Me closes the record.

The album introduction on Bugs, written by Starship Entertainment, presents the album behind the pre-release song ‘Delulu’ and the title track.

Reviews

Lee Jae-hun of IZM began his single review of the title track, dated 3 February 2026, with the way it reproduces an older sound. “The lead in making the time travel possible is LDN Noise,” he wrote, noting that the writing team behind SHINee’s ‘View’ and f(x)’s ‘4 walls’ reproduced a fragment of mid-2010s K-pop intact. Of the sound he wrote that “the intermittent arrival of a spacious bass over a plain house track is familiar and still sharp”, and closed: “widening their view and realising that a hint can be anywhere, only not found yet, KiiiKiii are advancing step by step into territory no signal picks up.”

Idology (아이돌로지) took the record twice, in the week of release and in that month’s page. In the ‘Weekly’ of 1 February 2026 Kwibi wrote of the pre-release song that “‘Delulu’, which dissolves dainty lyrics and a shy delivery into a sleek club sound, seems to show that KiiiKiii can put their own strangeness across without squaring their shoulders at all”, and Binunmul wrote that “the ‘Delulu’ narrative of girls building a world outside the system, ignoring plausibility and rules alike, declares a new generation with nerve as it passes through ‘MUNGNYANG’, varying on an odd beat, and ‘UNDERDOGS’, which attempts an aural overturning”.

In the ‘Monthly’ the same outlet published on 12 February, Yemi read the album as one continuous run. “The house beat that supports the soft vocal on ‘Delulu’ shows its full body on the title song ‘404 (New Era)’ and meets the members’ forceful rapping, and the passage up to ‘UNDERDOGS’, where that synth turns into high-register vocal chops and a hyperpop beat, keeps the listener dancing without a stop,” he wrote, and called it “a full album that rewards knowing the faces behind that identity — LDN Noise, Omega Sapien, Lee Seul-ah, Lil Cherry, Tablo”.

Jeong Ha-rim of IZM, reviewing the album on 7 February, set down why it drew attention from the pre-release stage. “The track film released ahead of it was already out of the ordinary,” he wrote, and of the record’s front half: “the refreshing tracks that put you in a good mood, and the visual devices behind them, met the message squarely.”

Billboard put the album on its staff list of the 25 best K-pop albums of 2026 so far, published on 20 July 2026. The entry, credited to Billboard Korea, says that “the group reaches for images and music from before its members were born, then translates them into a language native to the present”, and closes: “the voices remain loose and the sound slightly blurred, yet that haze renders their generation with unusual clarity.”

Among the tracks

‘404 (New Era)’ took the first place on Billboard’s staff list of the 25 best K-pop songs of 2026 so far, published on 15 July 2026. Jeff Benjamin wrote that “404 is the error that stops you in your scroll, but KiiiKiii heard something else in it”, and that “what earns the song our list’s top spot is that KiiiKiii doesn’t just imagine the new era; it pulls listeners fully inside it”. His entry ends: “‘404’ is no error. It’s a revolution.”

Of the same song Lee wrote that “Kiya’s solid low register, given room by the reduced share of melody, stands out clearly and works as a firm centre”, and noted that back vocals in falsetto widen the space even where the writing favours rhythm. Billboard Korea wrote that, arranged by LDN Noise, the song “plants garage swing inside U.K. house and pulls the force of classic club pop into KiiiKiii’s world”.

‘UNDERDOGS’ is the track Jeong picked out: “‘Underdogs’, which lifts a wistful melody to put courage into you, stands out for the vocal blend in its pre-chorus and bridge.” Of the pre-release song ‘Delulu’, Billboard Korea wrote that it “drains the tension from dreamy disco without letting it turn dated or obvious”.

Numbers

Takuo Matsumoto of Real Sound reported in a column of 22 March 2026 that ‘404 (New Era)’ reached number one on Melon’s weekly chart for 9 to 15 February and took the top of the service’s ‘TOP100’ on its sixteenth day out, holding that place day after day.
