From the moment KiiiKiii stepped onto the scene last September with their debut EP, UNCUT GEM, it was clear they weren’t just another girl group. Drawing heavily from 2000s fashion and iconography, their visual identity is matched by a sound that feels equally intentional – a confident blend of nostalgia and immediacy that grounds the group’s aesthetic rather than treating it as pastiche.

That bold, experimental approach evolves into something sleeker and more self-assured on their second EP, Delulu Pack, released on 26 January 2026. Across six tracks, the group pull from familiar 2000s sounds – dance-pop, electropop, and hints of R&B – while keeping their sense of play and youth front and centre. KiiiKiii lean fully into who they are, using nostalgia as a tool to create something freer and more immediately relatable.

“Delulu,” the EP’s opening track, was first shared as a pre-release music video on YouTube. The video itself is relatively simple, fading in and out between shots of the members superimposed over cityscapes, swaying in a club setting, and riding ATVs through a mountain landscape in frilly dresses. Rather than coming off as underdeveloped or overly stylised, the video’s imagery leans into restraint, using minimal visual effects to evoke the EP’s first wave of nostalgia.

Watching the members lip-sync directly to the camera as a fan blows their hair back isn’t new, but the ease of it recalls a different musical era altogether. The bouncy instrumental of “Delulu” provides the perfect dreamy backdrop to lyrics highlighting the imaginative inner monologue that lives inside each and every one of us. 

Whether it’s envisioning themselves as a group version of Kiki’s Delivery Service, dancing amongst a crowded room, or zooming through the sky, KiiiKiii encourages listeners to ignore the rules set in place for activities like dressing or walking. Their motto? “Start laughing / Start dreaming.”

The EP’s title track, “404 (New Era),” is an immediate sonic standout that similarly builds out the song’s identity through its music video. It starts with self-shot clips of the members gathering in their practice room to countdown the last minute of 2025. Right after a count of “3, 2, 1,” viewers are met with quick shots of childhood videos and text onscreen that reads: “What are you wishing for?”

The instrumental starts and the beat is matched with various home videos of the members as children dancing, singing, playing instruments, and performing. It feels as if viewers are being let into their origins – not just into their trainee days, but into the earliest proof of their dreams. In a way, we’re seeing a rapid fire timeline of each member’s evolution into this new era. 

The track itself is an incredibly poignant extension of their debut. It holds much of the same excited energy and joy that made UNCUT GEM such a memorable release, while also building off of that debut and incorporating the time at which they released Delulu Pack into its concept. Many people live by the motto of “new year, new me,” and KiiiKiii seems to be leaning into that. At the same time, they emphasize the importance of doing things your way, something they stated right off the bat with last year’s “I DO ME.”

Each of the EP’s four b-sides that follow are distinctly singular in the sonic landscape they paint. “UNDERDOGS” uses a laid back hyperpop and electropop sound to explicitly detail their identity as a K-pop group that knows they’ll have to work hard to gain the level of success they’re striving for. The imagery created by lyrics like “Now look at us, look in the mirror / This is a team fight, everyone push forward” is enough to make any listener root for KiiiKiii if their strong vocals and joyful spirit weren’t.

“MUNGNYANG” holds the most evident evolution from UNCUT GEM in its relaxed yet groovy chorus and how each piece of the song transitions into one another, similar to the structure of “THERE THEY GO” or “BTG.” “Dizzy” turns the energy down another notch, letting the members’ vocals take center stage, while “To Me From Me,” a mellow track that was originally released as a single on 4 November 2025, brings the energy down just enough to leave listeners feeling sated. 

Anyone familiar with KiiiKiii will likely recognise them from their debut or their shimmery summer single “DANCING ALONE.” On Delulu Pack, the group presents an identity shaped by approaching maturity, enduring joy, and deep-seated passion – qualities that first surfaced in their earliest memories. Their blend of 21st-century nostalgia and youthful sincerity continues to work firmly in their favour.
