K-pop girl group Billlie dropped its first full-length album, "the collective soul and unconscious: chapter two," Wednesday, delivering a dark, polished identity unlike anything the team has shown before.

Composed of seven members — Moon Sua, Suhyeon, Haram, Tsuki, Sheon, Siyoon and Haruna — the group has built a devoted following since its 2021 debut through standout tracks including "GingaMingaYo" (2022), "DANG! (hocus pocus)" (2023), "BYOB (bring your own best friend)" (2023) and "remembrance candy (prod. IU)" (2024).

"The collective soul and unconscious: chapter two" marks the group's first full-length release in five years of activity. Siyoon, Moon Sua and Haram contributed to the album's lyrics, adding a deeper personal layer to the project.

"Working on our first full-length brought back memories of our debut days. I hope we can show everyone how much more we have grown," she said.

"The members were deeply involved in the overall production process, and I think that really comes through. This album captures who we truly are," Moon Sua added.

The lead single "ZAP," premiered at the event, living up to its name. The track pairs a heavy, metallic bass with layered synthesizers, and the members' vocals cut through with relentless high notes.

The group described the song as a celebration of confidence, one that is "about shutting out the flood of external noise and returning fully to who you are," according to Moon Sua.
