KiiiKiii Tops Melon in 16 Days — No One Saw '404' Coming

Sixteen days. That's how long it took KiiiKiii, Starship Entertainment's newest girl group, to reach number one on Melon's daily chart with their track "404 (New Era)" — a feat that would be impressive for any established act, but is genuinely extraordinary for a group less than a year into their career. Released as the title track of their second EP "Delulu Pack" on January 26, 2026, the song didn't just chart well. It dominated, holding Melon's weekly top spot for two consecutive weeks and entering iTunes K-pop charts in 14 countries.

For a group that debuted just ten months earlier, in March 2025, the numbers represent a level of early traction that has the K-pop industry taking notice. KiiiKiii — five members who blend strong rap performances with airy vocals and a confident, self-possessed stage presence — appear to have cracked something that many new groups struggle to find: a sound that feels genuinely fresh while still connecting with the mainstream.

A Group Built for the Long Game

KiiiKiii debuted on March 24, 2025, with their first EP "Uncut Gem," and the signs were there from the start. Their debut single "I Do Me" earned them a victory on Show! Music Core just two weeks after launch — an early signal of what their fandom, called Kemi, was capable of when properly mobilized. But "Uncut Gem," while a strong introduction, was just the opening act.

The five members — Jiyu, Leesol, Sui, Haum, and Kya — represent a deliberately constructed range of vocal and performance profiles. Jiyu, the group's leader and oldest member, was born in 2005 and brings a grounded stage authority to the lineup. At the other end of the age spectrum, Kya — born in December 2010 — is one of K-pop's youngest active performers, a fact that has only amplified the group's appeal among fans who enjoy watching young artists grow in real time. Between them, Leesol's sharp rap delivery, Sui's delicate main vocal presence, and Haum's versatility as a dancer, rapper, and visual center give the group a dynamic range that reads well both on stage and on record.

Being signed to Starship Entertainment also comes with a built-in association: the agency is home to IVE, one of K-pop's biggest fourth-generation acts. The "IVE's sister group" tag has followed KiiiKiii since their announcement, but their music — particularly with "Delulu Pack" — suggests they're developing an identity that will eventually stand entirely on its own.

What Makes "404 (New Era)" Different

The key to understanding "404 (New Era)" is the production choice at its core. Rather than leaning into the familiar K-pop structures that have defined the past several years, the track is built on a UK house and UK garage foundation — a pulsing, rhythm-forward soundscape that has more in common with British dance music than with what most K-pop listeners might expect from a domestic chart-topper. The beat is insistent without being aggressive, creating a groove that the group's vocal layers can move within and against.

The concept adds a conceptual dimension that fans have responded to with genuine enthusiasm. The 404 error code — the internet's universal symbol for "not found" — is reframed here as a metaphor for freedom: the idea of stepping outside the boundaries of what's expected, of being unreachable by anyone who tries to contain you. It's a clever pivot, turning a technical error into a statement of self-possession, and it resonates particularly well given the group's "Delulu" era aesthetic, which embraces the kind of confident, slightly absurdist self-belief that has become a recurring theme in younger K-pop.

Acclaimed producer Omega Sapien of the alternative collective Balming Tiger contributed to the album's composition, lending the project additional credibility in music circles that track Korean indie and alternative influences on mainstream K-pop. Meanwhile, the album's b-side "To Me From Me" was produced by Tablo of Epik High — a collaboration that brought considerable attention from listeners who follow the legendary hip-hop duo's output as a barometer of artistic quality.

Chart Performance and What It Means

The specific numbers behind "404 (New Era)"'s chart run deserve to be examined closely, because they tell a story of organic growth rather than purely coordinated fan activity. The track reached Melon's daily top spot 16 days after release — on February 10 — and maintained that weekly chart position for two consecutive weeks running through late February. On YouTube Music, the song hit the daily and weekly number one position in Korea in the days immediately following release. Spotify Korea and Apple Music Korea both recorded top-position entries, while the song made inroads on Chinese platforms including QQ Music and NetEase Cloud Music.

The global iTunes K-pop chart entries — spanning 14 countries and regions — point to a fandom that, while still developing, has international reach from early in the group's career. The album "Delulu Pack" itself entered iTunes K-pop album charts in 13 markets. For context, many established groups with considerably larger fanbases fail to chart internationally with every release; KiiiKiii accomplishing it with their second EP speaks to a level of early global penetration that Starship's promotional strategy has clearly been built to support.

The show wins — at Show! Champion and Show! Music Core — completed a picture of a group performing at the top of almost every metric K-pop observers use to gauge a rookie act's momentum.

The Road Ahead

The question that will follow KiiiKiii through the rest of 2026 is whether the breakthrough of "404 (New Era)" can be sustained, expanded, and translated into the kind of long-term audience relationship that defines the most successful K-pop careers. The precedents from Starship's track record are encouraging: IVE successfully converted their debut momentum into sustained dominance, and the infrastructure supporting KiiiKiii — production partnerships, global distribution, the weight of Starship's industry relationships — is well-positioned to give them the runway they need.

What KiiiKiii has demonstrated with "Delulu Pack" is that they have something harder to manufacture than resources or industry connections: a genuine sense of who they are on record. The UK house influence, the "404" concept, the blend of youthful confidence and musical specificity — these are the building blocks of an identity, not just a campaign. Rookie acts that reach number one on Melon in 16 days occasionally fade as quickly as they rose. Those who do it by establishing a coherent artistic point of view tend to stay.

On the evidence of where they are ten months into their career, KiiiKiii looks very much like the latter kind of group. K-pop fans who haven't caught up yet may want to do so before the rest of the world does.
