The Cube Entertainment girl group also lands their first entry on Heatseekers Albums.

CLC said "No" and U.S. fans responded with a resounding "Yes!" when it came to the K-pop girl group's latest music.

The female outfit's new EP titled No.1 debuts at No. 5 on Billboard's World Albums chart, the group's highest entry yet. No.1 sold 1,000 copies in the week ending Jan. 31, according to Nielsen Music, marking their best U.S. sales week to date. The EP is also the highest debut on this week's World Albums chart.

CLC also make their first appearance on the Heatseekers Albums chart with No.1 starting at No. 19 on the chart. The Heatseekers tally sees far fewer K-pop acts bow and CLC is the first K-pop girl group since Red Velvet's RBB debuted back in December 2018.

Previous to No.1, CLC had landed three entries only World Albums. The act made two bows in 2017 with Crystyle (their first World Albums entry, which peaked at No. 6 in February) and Free'sm (which hit No. 14 in August). The girls also landed one more entry last year with their Black Dress EP which hit No. 7.

Notably, all of CLC's albums to enter the Top 10 or higher on World Albums have all seen the group showcasing a fiercer side of their image. The girl group initially debuted with a funky, fresh and innocent style (seen in the first single "Pepe") and played with that style until their dramatic revamp in 2017 with their hard-hitting "Hobgoblin" off their Crystyle EP which led to their first-ever Billboard chart entries. A quick switch back to a retro-influenced innocence with the citypop-inspried single "Where Are You" off their Free'sm knocked them down to No. 14, but their powerful image returned for Black Dress and, now, No.1 for continuing growth on the charts.

Elsewhere on Billboard's World Digital Song Sales chart, CLC's new single "No" debuts at No. 4 as the highest new entry on the chart, selling 1,000 copies in the week ending Jan. 31, according to Nielsen Music. "No" ties CLC's previous best on the chart when 2017's "Hobgoblin" also hit No. 4.

Celebrate the group's return by watching their CLC Comeback Showcase special, hosted by Korean broadcaster Mnet, that includes interviews, behind-the-scenes clips and performances of new No.1 tracks "Like It," "Show," the title track, plus "Black Dress."
